Hi, I have a disk /dev/hdb that appears to be physically damaged. It is in a volume group vg1. At some stage it was so bad that I could not see it raneb:# fdisk /dev/hdb Unable to open /dev/hdb I ran raneb:# vgreduce vg1 --removemissing but could not restore the volume group to run, it kept complaing that /dev/hdb was missing. I read http://www.novell.com/communities/node/1502/recovering+lost+lvm+volume+disk and tried to apply the procedure described in the section "disk permanently removed". I first had to order a new disk. A new 500G disk arrived today. After a long shutdown, today the disk appears visible again, miraculously. raneb:/etc/lvm/archive# fdisk -l /dev/hdb Disk /dev/hdb: 200.0 GB, 200049647616 bytes 255 heads, 63 sectors/track, 24321 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/hdb1 1 24321 195358401 83 Linux So I try to see it in lvm raneb:/etc/lvm/archive# pvdisplay Warning: Volume Group vg1 is not consistent --- Physical volume --- PV Name /dev/hdd1 VG Name vg1 PV Size 186.31 GB / not usable 3.69 MB Allocatable yes PE Size (KByte) 4096 Total PE 47694 Free PE 47694 Allocated PE 0 PV UUID vy3MOc-47sl-zUal-nhdO-FFX3-ispO-Rl0h8p --- Physical volume --- PV Name /dev/hdc VG Name vg1 PV Size 465.76 GB / not usable 4.02 MB Allocatable yes PE Size (KByte) 4096 Total PE 119234 Free PE 119234 Allocated PE 0 PV UUID NxRIE1-ROxx-pfjJ-QHzh-7B80-F7wt-kRCmSK I try to recover the metadata. The correct one is in vg1_00026.vg, because this is the version before the "vgreduce vg1 --removemissing". But raneb:/etc/lvm/archive# pvcreate --uuid v3HXpi-d5QN-OGiW-VFBG-TNIY-qTun-bFhlVd --restorefile vg1_00026.vg /dev/hdb uuid v3HXpi-d5QN-OGiW-VFBG-TNIY-qTun-bFhlVd already in use on "/dev/hdb1" I am puzzled. pvdisplay does not see the uuid value but pvcreate says it is is use?? What am I missing here?
