Ok I am now getting somewhere with this: I reinstalled LVM (but I am not sure what version I was running I think it was 1.0.5 - will this make a difference?) "pvscan" told me remaining LV and the VG they belong to: pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/sdc1" of VG "vg02" [9.85 GB / 0 free] pvscan -- inactive PV "/dev/sdc2" is associated to unknown VG "vg01" (run vgscan) pvscan -- inactive PV "/dev/sdd1" of VG "vg02" [19.54 GB / 0 free] pvscan -- inactive PV "/dev/sdd2" is associated to unknown VG "vg01" (run vgscan) pvscan -- total: 4 [64.35 GB] / in use: 4 [64.35 GB] / in no VG: 0 [0] vg02 was comprised of /dev/sdc1 and /dev/sdd1 which was /sw and /tmp so it can be rebuilt as sdc and sdd both still exist I tried to rebuild it: vgimport vg02 /dev/sdc1 /dev/sdd1 and recieved the error: vgimport -- error: physical volume "dev/sdc1" doesn't belong to exported volume group So I tried: vgimport -f vg02 /dev/sdc1 /dev/sdd1 vgimport -- physical volumes "/dev/sdd1" and "/dev/sdc1" are in different volume groups Run vgscan: [root@astro melinda]# /sbin/vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- found inactive volume group "vg02" vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of volume group "vg01" from physical volume(s) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume groups Obviously vg01 is going to be the biggest problem but as both lv's from vg02 still exist - how do I make it active? I then tried to mount it but it creates an error: /dev/vg02/lv02 is not a valid block device but it is there. So I am getting somewhere now at least but I presume I need to make everything active.
