There was new kernel built. /usr/src/linux pointed to new kernel source. But machine was not rebooted. So kernel version before kernel built was loaded. I rebooted machine. i renoved logical volume i created logical volume i tried to mount it and get: Aug 25 18:43:15 backupserver kernel: md4: unknown partition table Aug 25 18:43:15 backupserver syslog-ng[1417]: Internal error, alarm_set() called while an alarm is still active; Aug 25 18:43:56 backupserver kernel: md4: unknown partition table Aug 25 18:44:01 backupserver kernel: XFS (dm-2): Invalid superblock magic number pvdisplay shows: # pvdisplay --- Physical volume --- PV Name /dev/md4 VG Name VolGroup01 PV Size 2.69 TiB / not usable 1.25 MiB so what is XFS missing? _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
