After root filesystem failure my "/" was all messed up so i had to install system from scratch (Debian Unstable). /home is on separate LVM partition and (i hope so) intact. However pvscan and vgscan gives no result. According to fdisk partition is marked as "8e Linux LVM". I have LVM metadata backup which you can find here: http://pastebin.com/m5a13d266 At line 23 there is: 'device = "/dev/dm-7" # Hint only ', but there is no such device as /dev/dm-7. I think it should be rather /dev/dm-6 (I'm using dmraid), again according to fdisk - the size and type is correct. Should I change dm-7 into dm-6 or simply ignore it and do vgcfgrestore? And what does ' #Hint only' mean? Or maybe there is other way to recover LVM config? Thanks for any help.
Check dmraid. Twice. If *scan can't find a lvm pv, than there is something wrong. (unless you are filtering out /dev/dm* - check filter= in lvm.conf) Did you (or the Debian installation) change the partition layout? Where did you install the system to? I assume not to the old "lvroot" logical volume. Partition type (fdisk) means quite nothing. If the device/partition is a lvm PV, then there should be an lvm label at the beginning. That's what vgscan is looking for (see -vvv). If there is no label at the beginning, then: - we are looking at the wrong place - partition layout changed or perhaps dmraid changed it's mapping - we are looking at the correct place, but the label is not there You could try looking for the label at other places - man pvck. Either way provide some info: "lvmdump -m -a" can automate that or at least post dmsetup table, vgscan -vvv dmraid information Regards, Jaroslav Stava _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
