Bug#834416: Acknowledgement (xfs_growfs: XFS_IOC_FSGROWFSDATA xfsctl failed: Invalid argument)

[Marcel Meckel <debian@xxxxxxxxxxxx>]

Just had a chat in #xfs on freenode and it might be that a
previous xfs_growfs under an older kernel didn't zero enough.

When I recall it correctly the XFS filesystem in question was
resized in the past under then stable Debian Wheezy (might even
have been resized under Debian Squeeze).

Chat for reference:

< bfoster> strange, seems like it is running a verifier on the
           secondary sb's
< bfoster> e.g., commit 1375cb65e, but that fix seems to go way back
< bfoster> did growfs run and fail prior to the run with these
           reported errors?
< thermoman> bfoster: never had problems before
< thermoman> but the FS might have been created with an older
             xfsprogs and it has been definately be resized before
< bfoster> or hmm, perhaps its remnants from a previous growfs
< bfoster> ok, I think that makes more sense, you went from 109 ags
           to 160 some odd ags
< bfoster> and grow/repair is complaining about ags below that
           109 threshold
< bfoster> which suggests the previous grows didn't zero enough,
           or whatever that old problem was
< bfoster> I think the kernel you're on now should "do the right thing"
