Hi, When I try to access my lvm group (for example, running vgdisplay) I get the following error: Couldn't find device with uuid '5VBBLW-70Dj-fwjf-Xvzc-7VZr-icQa-l9XQ2N'. Couldn't find all physical volumes for volume group data. Couldn't find device with uuid '5VBBLW-70Dj-fwjf-Xvzc-7VZr-icQa-l9XQ2N'. Couldn't find all physical volumes for volume group data. Volume group "data" doesn't exist It happened just right after I deleted a /dev/hda6 (a *non-lvm* partition) and created two partitions in the space that the deleted partition was occupying (/dev/hda6 and /dev/hda8) (my idea was to shrink /dev/hda6, and that did work). Here's what the partition table looked before and after the change: before: Device Boot Start End Blocks Id System /dev/hda1 * 1 1459 11719386 8e Linux LVM /dev/hda2 1460 3891 19535040 83 Linux /dev/hda3 3892 14593 85963815 5 Extended /dev/hda5 3892 5107 9767488+ 8e Linux LVM /dev/hda6 5108 14225 73240303+ 83 Linux /dev/hda7 14226 14471 1975963+ 8e Linux LVM /dev/hda8 14472 14593 979933+ 82 Linux swap after: /dev/hda1 * 1 1459 11719386 8e Linux LVM /dev/hda2 1460 3891 19535040 83 Linux /dev/hda3 3892 14593 85963815 5 Extended /dev/hda5 3892 5107 9767488+ 8e Linux LVM /dev/hda6 11796 14225 19518943+ 8e Linux LVM /dev/hda7 14226 14471 1975963+ 8e Linux LVM /dev/hda8 5108 11795 53721328+ 83 Linux I looked up (in /etc/lvm) the uuid lvm was complaining about and found out it corresponds to /dev/hda7. This seems odd, /dev/hda7 should not have been affected by the partition deleting & creation... its start and end cylinder remained the same throughout the process and there was no partition overlapping. I thought maybe changing the uuid for /dev/hda7 in the /etc/lvm files, but I couldn't find how to get the correct uuid for /dev/hda7. What course of action do you suggest? Is it possible to get the data back? Thanks a lot, Oscar. _______________________________________________ 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/
