I recently had a lvm crash from which I now have to recover. So now I need= =20 your help ... The system is a SUSE 10.1 system with actual patches. # uname -rio 2.6.16.21-0.25-default i386 GNU/Linux # lvm version LVM version: 2.02.02 (2006-02-07) Library version: 1.02.03 (2006-02-08) Driver version: 4.5.0 # There was the unenlightened crash and before there was a volume goup spanni= ng=20 two physical partitions (sda2, sdb2), each on one physical disk (sda, sdb). The system froze (maybe in coincidence with some snapshot-handling) and I h= ad=20 to press the reset button. When rebooting lvm told me he could not open the= =20 volume group because one pv was missing. The partition looked OK when=20 checking the partition table. I tried several things - and to do a=20 vgcfgrestore but it did not help. The volume group (system_vg) contained the root partition, so I installed a= =20 new system on a third disc and tried to recover the old volume group. Unfortunately when doing the pvcreate for the two physical volumes I did NO= T=20 choose the "--zero n" switch. =46act is: I now have the volume group containing two physical discs and tw= o=20 physical volumes with the correct PV UUIDs. But the first sectors are zeroe= d,=20 aren't they? Any way to recover the LVs of the old volume group? A vgcfgrestore (YES, th= ere=20 was a vgcfgbackup before!) does not work ... bad luck. Ah - and all logical volumes contain Reiser Filesystems V 3.6 - they MUST=20 still be there ... So - what could be my next steps?
