1.) I unloaded the xfs modules, removed the selfcompiled xfs- module rpm and
installed the binary package from devs.centos.org. It was loaded with:
Apr 25 21:15:30 sz-linux02 kernel: SGI XFS with ACLs, security attributes, realtime, large block numbers, no debug enabled
Apr 25 21:16:46 sz-linux02 kernel: SGI XFS Quota Management subsystem
2.) I created with "mkfs.xfs /dev/md10" a new filesystem on the softraid mirror and mounted it
Apr 25 21:16:46 sz-linux02 kernel: Filesystem "md10": Disabling barriers, not supported by the underlying device
Apr 25 21:16:46 sz-linux02 kernel: XFS mounting filesystem md10
Apr 25 21:16:46 sz-linux02 kernel: SELinux: initialized (dev md10, type xfs), uses xattr
3.) I'm able to reproduce the same behaviour of corrupted XFS filesystem as I got
with my self compiled package by just copying bigger files onto the xfs volume. The
copyied files are corrupted (the md5sum gives a different result) and hava size between
10 MB and 3 GB. Finally "xfs_logprint /dev/md0" results in:
