[linux-lvm] Changing PV position

[linux-lvm] Changing PV position

[Benoit]

Hello,

I'm currently using lvm on my box and one disk just died.
Then the second disk (hdb) became the first one (hda). The problem is that now 
I can't get back the physical volume which is on it. Is it possible to tell 
lvm to force the reading of a PV even if it isn't on the same disk as 
before ?

Thank you for your help.
Benoit

I'm currently using linux 2.6-test9, with lvm2 tools. 
The missing volume was created with lvm1 tools.

[linux-lvm] Question: Fstab

[Stuart Felenstein]

[-- Attachment #1: Type: text/plain, Size: 477 bytes --]


After reading the docs and searching the archives I'm still a bit confusied on the issue of how to mount the logical volume I've created, upon bootup.

I can use the mount command and that seems to work fine.  vgscan detects it on boot.

Currently (and I've just really set up the system) is to issue

mount -t ext3 /dev/video_stor/logvol1 /mnt

then I can cd to /dev/video_stor

while I'm posting here in the dev/video_stor directory I see group and logvol1

Thanks

Stuart

I found the problem, my lvm.conf had a filter to dsable the scan of the first 
drive. So now vgchange -ay works. 

Thank you for your help and sorry for bugging you.
