用xfs_check检查xfs文件系统
[root@atyu30 ~]# xfs_check /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.

清除xfs文件中日志

[root@atyu30 ~]# xfs_repair -L /dev/sda1

[root@atyu30 ~]# mount /dev/sda1 /data/data027
