Please read these release notes carefully. + +Major Changes from Hammer +------------------------- + +- *General*: + + * Ceph daemons are now managed via systemd (with the exception of + Ubuntu Trusty, which still uses upstart). + * Ceph daemons run as 'ceph' user instead root. + * On Red Hat distros, there is also an SELinux policy. + +- *RADOS*: + + * The RADOS cache tier can now proxy write operations to the base + tier, allowing writes to be handled without forcing migration of + an object into the cache. + * The SHEC erasure coding support is no longer flagged as + experimental. SHEC trades some additional storage space for faster + repair. + * There is now a unified queue (and thus prioritization) of client + IO, recovery, scrubbing, and snapshot trimming. + * There have been many improvements to low-level repair tooling + (ceph-objectstore-tool). + * The internal ObjectStore API has been significantly cleaned up in order + to facilitate new storage backends like NewStore. + +- *RGW*: + + * The Swift API now supports object expiration. + * There are many Swift API compatibility improvements. + +- *RBD*: + + * The ``rbd du`` command shows actual usage (quickly, when + object-map is enabled). + * The object-map feature has seen many stability improvements. + * Object-map and exclusive-lock features can be enabled or disabled + dynamically. + * You can now store user metadata and set persistent librbd options + associated with individual images. + * The new deep-flatten features allows flattening of a clone and all + of its snapshots. (Previously snapshots could not be flattened.) + * The export-diff command command is now faster (it uses aio). There is also + a new fast-diff feature. + * The --size argument can be specified with a suffix for units + (e.g., ``--size 64G``). + * There is a new ``rbd status`` command that, for now, shows who has + the image open/mapped. + +- *CephFS*: + + * You can now rename snapshots. + * There have been ongoing improvements around administration, diagnostics, + and the check and repair tools. + * The caching and revocation of client cache state due to unused + inodes has been dramatically improved. + * The ceph-fuse client behaves better on 32-bit hosts. + +Distro compatibility +-------------------- + +We have decided to drop support for many older distributions so that we can +move to a newer compiler toolchain (e.g., C++11). Although it is still possible +to build Ceph on older distributions by installing backported development tools, +we are not building and publishing release packages for ceph.com. + +We now build packages for: + +* CentOS 7 or later. We have dropped support for CentOS 6 (and other + RHEL 6 derivatives, like Scientific Linux 6). +* Debian Jessie 8.x or later. Debian Wheezy 7.x's g++ has incomplete + support for C++11 (and no systemd). +* Ubuntu Trusty 14.04 or later. Ubuntu Precise 12.04 is no longer + supported. +* Fedora 22 or later. + +Upgrading from Firefly +---------------------- + +Upgrading directly from Firefly v0.80.z is not recommended. It is +possible to do a direct upgrade, but not without downtime. We +recommend that clusters are first upgraded to Hammer v0.94.4 or a +later v0.94.z release; only then is it possible to upgrade to +Infernalis 9.2.z for an online upgrade (see below). + +To do an offline upgrade directly from Firefly, all Firefly OSDs must +be stopped and marked down before any Infernalis OSDs will be allowed +to start up. This fencing is enforced by the Infernalis monitor, so +use an upgrade procedure like: + +#. Upgrade Ceph on monitor hosts +#. Restart all ceph-mon daemons +#. Upgrade Ceph on all OSD hosts +#. Stop all ceph-osd daemons +#. Mark all OSDs down with something like:: + + ceph osd down `seq 0 1000` + +#. Start all ceph-osd daemons +#. Upgrade and restart remaining daemons (ceph-mds, radosgw) + +Upgrading from Hammer +--------------------- + +* All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only + then is it possible to upgrade to Infernalis 9.2.z. + +* For all distributions that support systemd (CentOS 7, Fedora, Debian + Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd + files instead of the legacy sysvinit scripts. For example:: + + systemctl start ceph.target # start all daemons + systemctl status ceph-osd@12 # check status of osd.12 + + The main notable distro that is *not* yet using systemd is Ubuntu trusty + 14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.) + +* Ceph daemons now run as user and group ``ceph`` by default. The + ceph user has a static UID assigned by Fedora and Debian (also used + by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE + the ceph user will currently get a dynamically assigned UID when the + user is created. + + If your systems already have a ceph user, upgrading the package will cause + problems. We suggest you first remove or rename the existing 'ceph' user + and 'ceph' group before upgrading. + + When upgrading, administrators have two options: + + #. Add the following line to ``ceph.conf`` on all hosts:: + + setuser match path = /var/lib/ceph/$type/$cluster-$id + + This will make the Ceph daemons run as root (i.e., not drop + privileges and switch to user ceph) if the daemon's data + directory is still owned by root. Newly deployed daemons will + be created with data owned by user ceph and will run with + reduced privileges, but upgraded daemons will continue to run as + root. + + #. Fix the data ownership during the upgrade. This is the + preferred option, but it is more work and can be very time + consuming. The process for each host is to: + + #. Upgrade the ceph package. This creates the ceph user and group. For + example:: + + ceph-deploy install --stable infernalis HOST + + #. Stop the daemon(s):: + + service ceph stop # fedora, centos, rhel, debian + stop ceph-all # ubuntu + + #. Fix the ownership:: + + chown -R ceph:ceph /var/lib/ceph + chown -R ceph:ceph /var/log/ceph + + #. Restart the daemon(s):: + + start ceph-all # ubuntu + systemctl start ceph.target # debian, centos, fedora, rhel + + Alternatively, the same process can be done with a single daemon + type, for example by stopping only monitors and chowning only + ``/var/lib/ceph/mon``. + +* The on-disk format for the experimental KeyValueStore OSD backend has + changed. You will need to remove any OSDs using that backend before you + upgrade any test clusters that use it. + +* When a pool quota is reached, librados operations now block indefinitely, + the same way they do when the cluster fills up. (Previously they would return + -ENOSPC). By default, a full cluster or pool will now block. If your + librados application can handle ENOSPC or EDQUOT errors gracefully, you can + get error returns instead by using the new librados OPERATION_FULL_TRY flag. + +* The return code for librbd's rbd_aio_read and Image::aio_read API methods no + longer returns the number of bytes read upon success. Instead, it returns 0 + upon success and a negative value upon failure. + +* 'ceph scrub', 'ceph compact' and 'ceph sync force are now DEPRECATED. Users + should instead use 'ceph mon scrub', 'ceph mon compact' and + 'ceph mon sync force'. + +* 'ceph mon_metadata' should now be used as 'ceph mon metadata'.

There have been some +major changes since Hammer, and the upgrade process is non-trivial. +Please read carefully. + +Getting the release candidate +----------------------------- + +The v9.1.0 packages are pushed to the development release repositories:: + + http://download.ceph.com/rpm-testing + http://download.ceph.com/debian-testing + +For for info, see:: + + http://docs.ceph.com/docs/master/install/get-packages/ + +Or install with ceph-deploy via:: + + ceph-deploy install --testing HOST + + +Known issues +------------ + +* librbd and librados ABI compatibility is broken. Be careful + installing this RC on client machines (e.g., those running qemu). + It will be fixed in the final v9.2.0 release. + + +Major Changes from Hammer +------------------------- + +- *General*: + + * Ceph daemons are now managed via systemd (with the exception of + Ubuntu Trusty, which still uses upstart). + * Ceph daemons run as 'ceph' user instead of root. + * On Red Hat distros, there is also an SELinux policy. + +- *RADOS*: + + * The RADOS cache tier can now proxy write operations to the base + tier, allowing writes to be handled without forcing migration of + an object into the cache. + * The SHEC erasure coding support is no longer flagged as + experimental. SHEC trades some additional storage space for faster + repair. + * There is now a unified queue (and thus prioritization) of client + IO, scrubbing, and snapshot trimming. + * There have been many improvements to low-level repair tooling + (ceph-objectstore-tool). + * The internal ObjectStore API has been significantly cleaned up in order + to facilitate new storage backends like NewStore. + +- *RGW*: + + * The Swift API now supports object expiration. + * There are many Swift API compatibility improvements. + +- *RBD*: + + * The ``rbd du`` command shows actual usage (quickly, when + object-map is enabled). + * The object-map feature has seen many stability improvements. + * Object-map and exclusive-lock features can be enabled or disabled + dynamically. + * You can now store user metadata and set persistent librbd options + associated with individual images. + * The new deep-flatten features allows flattening of a clone and all + of its snapshots. (Previously snapshots could not be flattened.) + * The export-diff command command is now faster (it uses aio). There is also + a new fast-diff feature. + * The --size argument can be specified with a suffix for units + (e.g., ``--size 64G``). + * There is a new ``rbd status`` command that, for now, shows who has + the image open/mapped. + +- *CephFS*: + + * You can now rename snapshots. + * There have been ongoing improvements around administration, diagnostics, + and the check and repair tools. + * The caching and revocation of client cache state due to unused + inodes has been dramatically improved. + * The ceph-fuse client behaves better on 32-bit hosts. + +Distro compatibility +-------------------- + +We have decided to drop support for many older distributions so that we can +move to a newer compiler toolchain (e.g., C++11). Although it is still possible +to build Ceph on older distributions by installing backported development tools, +we are not building and publishing release packages for them on ceph.com. + +In particular, + +* CentOS 7 or later; we have dropped support for CentOS 6 (and other + RHEL 6 derivatives, like Scientific Linux 6). +* Debian Jessie 8.x or later; Debian Wheezy 7.x's g++ has incomplete + support for C++11 (and no systemd). +* Ubuntu Trusty 14.04 or later; Ubuntu Precise 12.04 is no longer + supported. +* Fedora 22 or later. + +Upgrading from Firefly +---------------------- + +Upgrading directly from Firefly v0.80.z is not possible. All clusters +must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only +then is it possible to do online upgrade to Infernalis 9.2.z. + +User can upgrade to latest hammer v0.94.z +from gitbuilder with(also refer the hammer release notes for more details):: + + ceph-deploy install --release hammer HOST + + +Upgrading from Hammer +--------------------- + +* All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only + then is it possible to do online upgrade to Infernalis 9.2.z. + +* For all distributions that support systemd (CentOS 7, Fedora, Debian + Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd + files instead of the legacy sysvinit scripts. For example:: + + systemctl start ceph.target # start all daemons + systemctl status ceph-osd@12 # check status of osd.12 + + The main notable distro that is *not* yet using systemd is Ubuntu trusty + 14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.) + +* Ceph daemons now run as user and group ``ceph`` by default. The + ceph user has a static UID assigned by Fedora and Debian (also used + by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE + the ceph user will currently get a dynamically assigned UID when the + user is created. + + If your systems already have a ceph user, the package upgrade + process will usually fail with an error. We suggest you first + remove or rename the existing 'ceph' user and then upgrade. + + When upgrading, administrators have two options: + + #. Add the following line to ``ceph.conf`` on all hosts:: + + setuser match path = /var/lib/ceph/$type/$cluster-$id + + This will make the Ceph daemons run as root (i.e., not drop + privileges and switch to user ceph) if the daemon's data + directory is still owned by root. Newly deployed daemons will + be created with data owned by user ceph and will run with + reduced privileges, but upgraded daemons will continue to run as + root. + + #. Fix the data ownership during the upgrade. This is the preferred option, + but is more work. The process for each host would be to: + + #. Upgrade the ceph package. This creates the ceph user and group. For + example:: + + ceph-deploy install --stable infernalis HOST + + #. Stop the daemon(s):: + + service ceph stop # fedora, centos, rhel, debian + stop ceph-all # ubuntu + + #. Fix the ownership:: + + chown -R ceph:ceph /var/lib/ceph + chown -R ceph:ceph /var/log/ceph + + #. Restart the daemon(s):: + + start ceph-all # ubuntu + systemctl start ceph.target # debian, centos, fedora, rhel + +* The on-disk format for the experimental KeyValueStore OSD backend has + changed. You will need to remove any OSDs using that backend before you + upgrade any test clusters that use it. + +Upgrade notes +------------- + +* When a pool quota is reached, librados operations now block indefinitely, + the same way they do when the cluster fills up. (Previously they would return + -ENOSPC). By default, a full cluster or pool will now block. If your + librados application can handle ENOSPC or EDQUOT errors gracefully, you can + get error returns instead by using the new librados OPERATION_FULL_TRY flag. + +Notable changes +--------------- + +NOTE: These notes are somewhat abbreviated while we find a less +time-consuming process for generating them. + +* build: C++11 now supported +* build: many cmake improvements +* build: OSX build fixes (Yan, Zheng) +* build: remove rest-bench +* ceph-disk: many fixes (Loic Dachary) +* ceph-disk: support for multipath devices (Loic Dachary) +* ceph-fuse: mostly behave on 32-bit hosts (Yan, Zheng) +* ceph-objectstore-tool: many improvements (David Zafman) +* common: bufferlist performance tuning (Piotr Dalek, Sage Weil) +* common: make mutex more efficient +* common: some async compression infrastructure (Haomai Wang) +* librados: add FULL_TRY and FULL_FORCE flags for dealing with full clusters or pools (Sage Weil) +* librados: fix notify completion race (#13114 Sage Weil) +* librados, libcephfs: randomize client nonces (Josh Durgin) +* librados: pybind: fix binary omap values (Robin H.

The most intrusive change is an internal (non +user-visible) change to the OSD's ObjectStore interface. Many fixes and +improvements elsewhere across RGW, RBD, and another big pile of CephFS +scrub/repair improvements. + +Upgrading +--------- + +* The return code for librbd's rbd_aio_read and Image::aio_read API methods no + longer returns the number of bytes read upon success. Instead, it returns 0 + upon success and a negative value upon failure. + +* 'ceph scrub', 'ceph compact' and 'ceph sync force' are now deprecated. Users + should instead use 'ceph mon scrub', 'ceph mon compact' and + 'ceph mon sync force'. + +* 'ceph mon_metadata' should now be used as 'ceph mon metadata'. + +* The `--dump-json` option of "osdmaptool" is replaced by `--dump json`. + +* The commands of 'pg ls-by-{pool,primary,osd}' and 'pg ls' now take 'recovering' + instead of 'recovery' to include the recovering pgs in the listed pgs.
