Previously an IMSM array would only -be assembled if it was attached to an IMSM controller. - -In 3.3 this was relaxed as there are circumstances where the -controller is not properly detected. Unfortunately this has negative -consequences which have only just come to light. - -If you have an IMSM RAID1 configured and then disable RAID in the -BIOS, the metadata will remain on the devices. If you then install -some other OS on one device and then install Linux on the other, Linux -might eventually start noticing the IMSM metadata (depending a bit on whether -mdadm is included in the initramfs) and might start up the RAID1. This could -copy one device over the other, thus trashing one of the installations. - -Not good. - -So with this release IMSM arrays will only be assembled if attached to -an IMSM controller, or if "--force" is given to --assemble, or if the -environment variable IMSM_NO_PLATFORM is set (used primarily for -testing). - -I strongly recommend upgrading to 3.3.4 if you are using 3.3 or later. - -NeilBrown 3rd August 2015. |
