i rebootet the machine and created a new logical volume.
i formatted the lv with mkfs.xfs
i tried to mount it on the new kernel:
Aug 26 00:47:17 backupserver kernel: XFS (dm-2): Version 5
superblock detected. This kernel has EXPERIMENTAL support enabled!
Aug 26 00:47:17 backupserver kernel: Use of these features in this
kernel is at your own risk!
Aug 26 00:47:17 backupserver kernel: XFS (dm-2): Superblock has
unknown read-only compatible features (0x1) enabled.
Aug 26 00:47:17 backupserver kernel: XFS (dm-2): Attempted to mount

mounted read only.
Aug 26 00:47:17 backupserver kernel: XFS (dm-2): SB validate failed

this happens with the newly created logical volume.
the other 2 lvm partitions with xfs are fine.
any idea?
Clearly you have a kernel too old to read the on-disk format that
mkfs.xfs has written - as I pointed out originally.
Would you please tell us what the versions of the kernels
you are using, as well as the mkfs.xfs version?
Kernel vanilla-sources 3.14.51 (longterm support)
xfs-progs 3.2.4 (gentoo)
mkfs.xfs 3.2.4
AND HEY! Eric, your hint worked:

dave, so the latest lts kernel 3.14.51 does not support to mount lvm2
partitions formatted with mkfs.xfs 3.2.4?
marko
Cheers,
Dave.
