Package: linux-source-2.6.26 Version: 2.6.26-21 Severity: normal Hi,
I just experienced an XFS corruption on one of my machines during a remote run of rdiff-backup. No indications of I/O errors or hardware problems. The XFS volume runs on top of a encrypted loop-aes device, on top of lvm, on top of software raid 1. I've been using this setup for years without any problems. After this, xfs refuses to mount again, and xfs_repair only runs with -L to ignore the log. The filesystem is up now again and I'm trying to figure out the damage. I still have the original corrupted one as an lvm snapshot. Here are the syslog messages and the xfs_repair output. | Feb 11 23:46:07 marvin kernel: XFS internal error XFS_WANT_CORRUPTED_GOTO at line 1650 of file fs/xfs/xfs_alloc.c.
