RE: [linux-lvm] Ut-Oh! - I need MAJOR help.



Thanks for the info, gave it a go, but am still getting:

vgscan -- found inactive volume group "vg01"
vgscan -- reading data of volume group "vg01" from physical volume(s)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get
data of volume group "vg01" from physical volume(s)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" creating
"/etc/lvmtab" and "/etc/lvmtab.d"

Is there any hope?

Thanks

Justin

Hi Justin,

are all PVs of your vg01 online and accessable after your repairs?

If so, your VGDAs got screwed somehow (maybe heat problems screwed date)
and you need to use vgcfgrestore(8) to restore the recent consistent VGDA
backup
from /etc/lvmconf/ to your PVs like:

   vgcfgrestore -n vg01 -f /etc/lvmconf/vg01.conf /dev/PhysicalVolumeDevice

Repeat this step for all your PVs and try vgscan/vgchange again.

If none of your PEs got screwed too, you should be fine after this.
Nevertheless I am afraid that you will most likely face filesystem damage as
well, if you run your machine with seriuos CPU heat trouble for a longer
period
of time.
