Синопсис (Synopsis)

xfs_logprint [ options ] device

Описание (Description)

xfs_logprint prints the log of an XFS filesystem (see xfs(5)).
       The device argument is the pathname of the partition or logical
       volume containing the filesystem. The device can be a regular
       file if the -f option is used. The contents of the filesystem
       remain undisturbed.  There are two major modes of operation in
       xfs_logprint.

       One mode is better for filesystem operation debugging.  It is
       called the transactional view and is enabled through the -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.

       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.

Параметры (Options)

-b     Extract and print buffer information. Only used in
              transactional view.

       -c     Attempt to continue when an error is detected.

       -C filename
              Copy the log from the filesystem to the file filename.
              The log itself is not printed.

       -d     Dump the log from front to end, printing where each log
              record is located on disk.

       -D     Do not decode anything; just print data.

       -e     Exit when an error is found in the log. Normally,
              xfs_logprint tries to continue and unwind from bad logs.
              However, sometimes it just dies in bad ways.  Using this
              option prevents core dumps.

       -f     Specifies that the filesystem image to be processed is
              stored in a regular file at device (see the mkfs.xfs(8) -d
              file option).  This might happen if an image copy of a
              filesystem has been made into an ordinary file with
              xfs_copy(8).

       -l logdev
              External log device. Only for those filesystems which use
              an external log.

       -i     Extract and print inode information. Only used in
              transactional view.

       -q     Extract and print quota information. Only used in
              transactional view.

       -n     Do not try and interpret log data; just interpret log
              header information.

       -o     Also print buffer data in hex.  Normally, buffer data is
              just decoded, so better information can be printed.

       -s start-block
              Override any notion of where to start printing.

       -t     Print out the transactional view.

       -v     Print "overwrite" data.

       -V     Prints the version number and exits.
