XFS internal error xfs_trans_cancel at line 1138 of file fs/xfs/xfs_trans.c

[Wolfgang Karall <spiney@xxxxxxxxxx>]

Hello,

today I ran across above error, resulting in an unaccessible FS,  
after remounting once xfs_repair didn't show any signs of errors. At  
the time of the error the machine and also the concerned FS was under  
rather high I/O load (doing test restores of some SVN repositories).

The FS is now working again without a hitch (and did before for close  
to a year), latest operation on the filesystem was an xfs_growfs a  
couple of days ago. I read a couple of reports about similiar errors  
(with differing line numbers), but didn't find conclusive  
information, so I'm asking here what the problem might be.

For details see below, if anything is amiss, please let me know. And  
please CC me on the replies, since I'm not subscribed to the list.

Kind regards
Wolfgang Karall
