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



Just had my machine lock up after CPU Fan failure.  Anyway, after repairs, a
reboot (and subsequent vgscan's) gives the following response:

[root Voyager /root]# vgscan -v
vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d"
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- scanning for all active volume group(s) first
vgscan -- found active volume group "vg02"
vgscan -- reading data of volume group "vg02" from physical volume(s)
vgscan -- inserting "vg02" into lvmtab

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"


How screwed am I?

I've got reiserfs on the LV's, so recovering the data from the LV's should
not be too big an issue.  What I need to know is how to rebuild the VG.

TIA

Justin Hamilton.
