Thanks for your reply.
Is there some points I should notice about when using xfs_repair? I
used to encounter some cases in which xfs_repair complete successfully
but some errors like "Corrupt in memory detected" occured when the
filesytem is put into online for short time.
Should I reboot the machine and use xfs_repair before the damaged
filesystem is used, or some other options I should use?
In addition, I googled some information and found that some people say
xfs_check should be used before xfs_repair, is it right?
