Hallo :) When shutting down my PC yesterday I saw something from LVM complaining, but that scrolled to fast... When booting it today all my LVs were inaccessible. Problem seems to be some error in some metadata (?) this is the first error message: -------------------------------------------------------------------------- Apr 22 08:17:34 [lvm] WARNING: Duplicate VG name vg0: Existing K0qKAk-Ph5i-BcAX-y4yp-SPF3-TZgj-DufR3L (created here) takes precedence over K0qKAk-Ph5i-BcAX-y4yp-SPF3-TZgj-DufR3L -------------------------------------------------------------------------- I googled for somebody with a similar problem, but found nothing... After successful scanning for my LVs (they are all there :) I tried some renaming of the PVs UUIDs, which worked, but never removed that old reference to the VGs UUID (K0qKAk...) I even renamed the VG (vg0 -> vg1), exported it, imported it... now all PVs and the VG have different UUIDs than before, but I still can't get my device-nodes, so that I can access my data. Original UUID of the VG is "K0qKAk-Ph5i-BcAX-y4yp-SPF3-TZgj-DufR3L", an "vg0" was it's original name. Now it's "vg1" and "JtUveN-SL2N-cTrH-X2GI-NVux-3kYH-NJwRt5". Sorry... maybe I was a bit desperate to get to my data when fooling around with the LVM-tools... -------------------------------------------------------------------------- akira ~ # lvm version Logging initialised at Sat Apr 22 09:54:11 2006 Set umask to 0077 LVM version: 2.02.04 (2006-04-19) Library version: 1.02.03 (2006-02-08) Driver version: 4.5.0 Wiping internal VG cache akira ~ # pvscan -u Logging initialised at Sat Apr 22 09:46:30 2006 Set umask to 0077 Wiping cache of LVM-capable devices Wiping internal VG cache Walking through all physical volumes WARNING: Duplicate VG name vg1: Existing JtUveN-SL2N-cTrH-X2GI-NVux-3kYH-NJwRt5 takes precedence over exported K0qKAk-Ph5i-BcAX-y4yp-SPF3-TZgj-DufR3L WARNING: Duplicate VG name vg1: Existing JtUveN-SL2N-cTrH-X2GI-NVux-3kYH-NJwRt5 (created here) takes precedence over K0qKAk-Ph5i-BcAX-y4yp-SPF3-TZgj-DufR3L PV /dev/sda7 with UUID ZKdlL6-18Z7-YX8T-bH2J-IS3u-azbG-bUMLel is in exported VG vg1 [4.66 GB / 4.66 GB free] PV /dev/sda8 with UUID ezIhm5-iaCJ-YhCl-Mtdg-2m66-z35A-9OdFJW is in exported VG vg1 [4.66 GB / 4.66 GB free] PV /dev/sda11 with UUID n8POw9-c8fg-E39z-whvX-9lgA-P2ls-8n1jMa is in exported VG vg1 [56.76 GB / 20.76 GB free] Total: 3 [66.09 GB] / in use: 3 [66.09 GB] / in no VG: 0 [0 ] Wiping internal VG cache akira ~ # vgscan -v Logging initialised at Sat Apr 22 09:47:30 2006 Set umask to 0077 Wiping cache of LVM-capable devices Wiping internal VG cache Reading all physical volumes.
