Dear community,
I had the following problem with my lvm raid:
Jan 22 10:51:08 sky kernel: jfs_lookup: iget returned bad inode, inum = 249888
Jan 22 10:51:08 sky kernel: jfs_lookup: iget returned bad inode, inum = 229376
Jan 22 10:51:08 sky kernel: I/O error: dev 08:41, sector 40845696
Jan 22 10:51:08 sky kernel: I/O error: dev 08:41, sector 19874184
The LVM (LVM 1) consists of six SCSI disks, each one 36Gb size.
I decided to reboot the machine and see what happens. The reboot was the
first one since I configured the LVM a few _months_ ago.
After the reboot the system can't bring the LVM back online and reports:
[root]sky: ~>pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/sdb1" is associated to unknown VG "softraid" (run

and

vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of volume

vgscan -- WARNING: This program does not do a VGDA backup of your volume group
vgcfgrestore reported success, but no change to pvscan and vgscan .
/dev/softraid/ disappeared after the reboot
/etc/lvmconf/softraid exists and has size of 1375404 bytes .
/etc/lvmtab and /etc/lvmtab.d are empty.
I have valuable data on the raid I do not want to go through restoring
from a backup again.
Any advice how to recover and reconfigure the volume group?
Thanks in advance,
Roman.
