hello.

I had problem with raid5 on my system.
after recovering of the array, I can not mount XFS that resides on it.
I've run xfs_check and xfs_repair (which fixed some errors) and now I can
run them all day long without any errors.

but, when I try to mount that partition, I get:

mount: /dev/md0: can't read superblock


and there's

Filesystem "md0": Disabling barriers, not supported by the underlying device
attempt to access beyond end of device
md0: rw=0, want=123024384, limit=123023488
I/O error in filesystem ("md0") meta-data dev md0 block 0x75533f8
 ("xfs_read_buf") error 5 buf count 4096
XFS: size check 2 failed



in the dmesg.


is there any way to "fix" this wrong size of XFS ?

thx.
