[linux-lvm] It never rains...




Hi All,

Had a bit a disaster, lost 1 disk from a 3 disk VG and the root partition! All  on fully patched RH 9 system.
I realise that I need to attach the 2 remaining PV to a LV and VG but if I do the usual vgcreate, lvcreate & pvcreate I'll end up with two dataless disks.
I luckly do have backups of some of the more important data but there not a recenct as I'd like and don't contain all of the data or the root partition.

Outputs from:

vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of volume group "datavg" 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 group

pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/sda1"  is associated to unknown VG "datavg" (run vgscan)
pvscan -- inactive PV "/dev/hdc1"  is associated to unknown VG "datavg" (run vgscan)
pvscan -- total: 2 [45.75 GB] / in use: 2 [45.75 GB] / in no VG: 0 [0]
