Hi, The following is on an Ubuntu 7.04 server running LVM2 that I have remote access to. I have put the output of vgscan, vgdisplay etc, various logs and a copy the archive and backup directories at http://www.dubh.id.au/lvm/ with more details of the problem in 00-notes. I had a lvm volume that held a cryptsetup encrypted volume[1]. The server was rebooted without unmounting the encrypted volume. On reboot the lvm volume wasn't present in /dev/mapper. Vgdisplay displayed an error saying something similar to "UUID Z1tlHa-60OU-iymQ-nQJu-z9OD-abno-PkxUC5 not found" (sorry the original error wasn't recorded, but the UUID string is correct). At the time it was noted that the boot order of the drives had changed and was thought we were just missing a small partition off one of the disks. 'vgreduce --removemissing lvm_vol_grp_1' was run. This stopped the error from occurring but the volume still wasn't present in /dev/mapper. We have since realised that one of the drives (/dev/sdd) isn't being recognised on boot. All other drives and partitions are shown correctly in the output of pvscan. Would someone be able to please look at the information provided and point me in the direction of a solution. Many thanks, Nigel [1] I mention this in case cryptsetup is somehow involved.
