Unable to mount or check XFS filesystem
Issue
-
A XFS filesystem hangs and running
xfs_repair -nv /dev/sda1
the following error is returned:# xfs_repair -n /dev/sda1 ERROR: The filesystem has valuable metadata changes in a log which needs to be replayed. Mount the filesystem to replay the log, and unmount it before re-running xfs_check. If you are unable to mount the filesystem, then use the xfs_repair -L option to destroy the log and attempt a repair. Note that destroying the log may cause corruption -- please attempt a mount of the filesystem before doing this.
NOTE: Older
xfsprogs
releases used to ship thexfs_check
tool, however it was very slow and did not scale well for large filesystems. As such, it has been deprecated in favor ofxfs_repair -n
. -
In the above scenario, the filesystem would also not mount:
# mount /dev/sda1 /mountpoint/ mount: Structure needs cleaning
-
The last resort is running
xfs_repair -L
, which will clean the entries in the transaction log journal and ultimately allow the filesystem to be mounted.kernel: XFS internal error XFS_WANT_CORRUPTED_GOTO at line 1572 of file fs/xfs/xfs_alloc.c.
