Phil, I thought it was fixed, but every time I do a reboot it disappears again. I did the: pvcreate --restorefile 'simons-lvm-backup' --uuid 9fAJEz-HcaP-RQ51-fV8b-nxrN-Uqwb-PPnOLJ /dev/md0 and the vgcfgrestore the only piece of your advice that I didn't follow was "zero the superblock on the removed drive" as I thought re-adding it to the array would do that anyway. Did this cause me problems ? proxmox:~# mdadm --assemble --scan -v mdadm: looking for devices for /dev/md/0 mdadm: cannot open device /dev/dm-2: Device or resource busy mdadm: /dev/dm-2 has wrong uuid. mdadm: cannot open device /dev/dm-1: Device or resource busy mdadm: /dev/dm-1 has wrong uuid. mdadm: cannot open device /dev/dm-0: Device or resource busy mdadm: /dev/dm-0 has wrong uuid. mdadm: /dev/sdo1 has wrong uuid. mdadm: no RAID superblock on /dev/sdo mdadm: /dev/sdo has wrong uuid. mdadm: /dev/sdn1 has wrong uuid. mdadm: no RAID superblock on /dev/sdn mdadm: /dev/sdn has wrong uuid. mdadm: /dev/sdm1 has wrong uuid. mdadm: no RAID superblock on /dev/sdm mdadm: /dev/sdm has wrong uuid. mdadm: /dev/sdl1 has wrong uuid. mdadm: no RAID superblock on /dev/sdl mdadm: /dev/sdl has wrong uuid. mdadm: /dev/sdk1 has wrong uuid. mdadm: no RAID superblock on /dev/sdk mdadm: /dev/sdk has wrong uuid. mdadm: /dev/sdj1 has wrong uuid. mdadm: no RAID superblock on /dev/sdj mdadm: /dev/sdj has wrong uuid. mdadm: /dev/sdi1 has wrong uuid. mdadm: no RAID superblock on /dev/sdi mdadm: /dev/sdi has wrong uuid. mdadm: /dev/sdh1 has wrong uuid. mdadm: no RAID superblock on /dev/sdh mdadm: /dev/sdh has wrong uuid. mdadm: /dev/sdg1 has wrong uuid. mdadm: no RAID superblock on /dev/sdg mdadm: /dev/sdg has wrong uuid. mdadm: /dev/sdf1 has wrong uuid. mdadm: no RAID superblock on /dev/sdf mdadm: /dev/sdf has wrong uuid. mdadm: cannot open device /dev/sdc1: Device or resource busy mdadm: /dev/sdc1 has wrong uuid. mdadm: cannot open device /dev/sdc: Device or resource busy mdadm: /dev/sdc has wrong uuid. mdadm: cannot open device /dev/sdb1: Device or resource busy mdadm: /dev/sdb1 has wrong uuid. mdadm: cannot open device /dev/sdb: Device or resource busy mdadm: /dev/sdb has wrong uuid. mdadm: cannot open device /dev/sda2: Device or resource busy mdadm: /dev/sda2 has wrong uuid. mdadm: cannot open device /dev/sda1: Device or resource busy mdadm: /dev/sda1 has wrong uuid. mdadm: cannot open device /dev/sda: Device or resource busy mdadm: /dev/sda has wrong uuid. I'm getting frustrated now. It seems like it's fixzed, then next reboot, BAM, it's gone again. I'm so out of my depth here. Please can you help me fix this once and for all ? cheers Simon On 20 February 2011 23:39, Phil Turmel <philip@xxxxxxxxxx> wrote: > On 02/20/2011 06:17 PM, Simon Mcnair wrote: >> Phil, >> You are a god amongst men :-) > > Heh.
