Hi!
I have find myself in a troublesome spot. After a disk failure, with
lots of IDE bus timeouts etc i managed to get the disk in error replaced
and my raid5 set in full operation. But i can't get the volume group
active any more. The volume group in question is VG1.
I have read one year worth of messages in this list archives, and i
still can't se how i can recover my VG1.
Please find the details below

Martin,
based on the error (vgscan -- ERROR "lv_read_all_lv(): number of LV" can't
get data of volume group "vg1" from physical volume(s)), it looks like
vgscan counts a different number rather than 1 LV scanning the on-disk table
of LV structures.
Could you send the output of "vgscan -d" to me in private email
(mge@sistina.com) and attach the file Martin_md0.vgda you created with
"dd if=/dev/md0 of=Martin_md0.vgda bs=1k count=1024" as well for further
investigation.
Regards,
Heinz -- The LVM Guy --
