Hello, two days ago i installed a new HDD and added it to my VG 'vg1' (partition id '8e' + 'pvcreate /dev/hdb1' + 'vgextend vh1 /dev/hdb1'). A bit later I erroneously formatted '/dev/hdb1' by 'mkfs.xfs /dev/hdb1'. I ran 'vgscan' and 'pvscan' and the made a smiliar output like it is shown on http://lists.sistina.com/pipermail/linux-lvm/2002-August/011947.html - but i have only two PVs in my VG 'vg1': '/dev/hdc1' and '/dev/hdd2'. I don't remember what i exactly did with '/dev/hdb' after that (it was late...), but as a result I 'fdisked' the partition table away... There was no data on '/dev'hdb' (except the LVM metadata), so no 'real' data needs to be recovered (at least i hope so). All in all, I can't access the VG 'vg1' (PVs: '/dev/hdc1' + '/dev/hdd2') with the 3 LVs 'root', 'storage' and 'swap' any more. Now you could advise me to run 'vgcfgrestore', but i regretfully must say that i rebooted my box and as the name of the LV 'root' implies, my root-filesystem was on it, so the system doesn't boot anymore *doh*... Summary: - 1 VG: 'vg1' - 2 (3) PVs: '/dev/hdc1' + '/dev/hdd2' + for a short time (see above) '/dev/hdb1' - 3 LVs: 'root', 'storage' and 'swap' - Filesystem on all LVs: XFS Fortunately i have a separated 'backup system' on another HDD, which doesn't use LVM nor XFS, but simply ext2, so i can work with it temporarily to fix this disaster. I think the problem is, that the VG 'vg1' still thinks, it would consist of 3 PVs, but only 2 are there. But because no VG is found by 'vgscan' (see link above), i can't remove '/dev/hdb1' by 'vgreduce vg1 /dev/hdb1' and so on... Is there any way to generate metadata for '/dev/hdb1' to make it known by 'vg1' or remove '/dev/hdb1' from 'vg1'?! I'm very despaired and would be gladdened by every answer. If you need any details, just ask. P.S.: This is not intended to be a cross-posting; I only had problems submitting my first one. Kind regards and thanks in advance Tim-Patrick Märk _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
