and why xfs_repair didnt repaired it ?

xfs_repair doesn't check the free space btrees, it simply rebuilds them from scratch. Hence it won't warn about a corrupted AGF btree during repair. However, after a repair they should be consistent.

OTOH, xfs_check will actually check the AGF btrees for corruption
and consistency. Can you run xfs_check on the filesystem after one of
these errors both before and after you run xfs_repair, and post
the output?

i can't run it so often, because to run it i think i have to unmount my filesystem. and of course this means longer downtime for my users, which for now i just can't do.


Maybe there is some kind of bug with this situation, because i forgot to tell you one thing: i have one more XFS partition that is inside this one big XFS partition.


guess it's not. it crashed again after i removed loop-mounted XFS partition - so that's not it. i also ran xfs_check on unmounted system, but output was empty. it just didn't say anything, and finished checking after like 10-20 minutes with no output. is it normal? i did xfs_check /dev/md0 1>>logs 2>>logs. And it finished with file logs with 0 bytes. Should i run it with -v ? -v generates a lot of output though.
