The +.I device +can be a regular file if the +.B \-f +option is used. The contents of the filesystem remain undisturbed. +There are two major modes of operation in +.BR xfs_logprint . +.PP +One mode is better for filesystem operation debugging. +It is called the transactional view and is enabled through the +.B \-t +option. The transactional view prints only the portion of the log that +pertains to recovery. In other words, it prints out complete transactions +between the tail and the head. This view tries to display each transaction +without regard to how they are split across log records. +.PP +The second mode starts printing out information from the beginning of the log. +Some error blocks might print out in the beginning because the last log +record usually overlaps the oldest log record. A message is +printed when the physical end of the log is reached and when the +logical end of the log is reached. A log record view is displayed +one record at a time. Transactions that span log records may not be +decoded fully. +.SH OPTIONS +.TP +.B \-b +Extract and print buffer information. Only used in transactional view. +.TP +.B \-c +Attempt to continue when an error is detected. +.TP +.BI \-C " filename" +Copy the log from the filesystem to the file +.IR filename . +The log itself is not printed. +.TP +.B \-d +Dump the log from front to end, printing where each log record is located +on disk. +.TP +.B \-D +Do not decode anything; just print data. +.TP +.B \-e +Exit when an error is found in the log. Normally, +.B xfs_logprint +tries to continue and unwind from bad logs. +However, sometimes it just dies in bad ways. +Using this option prevents core dumps. +.TP +.B \-f +Specifies that the filesystem image to be processed is stored in a +regular file at +.I device +(see the +.BR mkfs.xfs "(8) " -d +.I file +option). +This might happen if an image copy of a filesystem has been made into +an ordinary file with +.BR xfs_copy (8). +.TP +.BI \-l " logdev" +External log device. Only for those filesystems which use an external log. +.TP +.B \-i +Extract and print inode information. Only used in transactional view. +.TP +.B \-q +Extract and print quota information. Only used in transactional view. +.TP +.B \-n +Do not try and interpret log data; just interpret log header information. +.TP +.B \-o +Also print buffer data in hex. +Normally, buffer data is just decoded, so better information can be printed. +.TP +.BI \-s " start-block" +Override any notion of where to start printing. +.TP +.B \-t +Print out the transactional view. +.TP +.B \-v +Print "overwrite" data. +.TP +.B \-V +Prints the version number and exits. +.SH SEE ALSO +.BR mkfs.xfs (8), +.BR mount (8). |
