xfs-2.5.6 as installed according to "Beyond Linux From Scratch" don't have this problem. However, it's impossible to compile them, because their ./configure script detects sizeof(char, int, pointer, long) to be 0 and then compilation of xfs-2.5.6 crashes.
I thnk this is due to a bug in xfsprogs-2.3.9 in libdisk/md.c line 73 where the clean state test is incorrect: if (md.state) { ... } Should be: if (md.state & (1 << MD_SB_ERRORS)) { ... }
Has there been any resolution to this issue with xfsprogs-2.3.9? Is xfsprogs-2.3.9 going to be patched to fix this or is the stable version going to be bumped to xfsprogs-2.6.0? I ran into this same problem when trying to setup a raid-5 partition
2.6.13 is now stable
