Unfortunately I did reboot before I noticed the typo. After the reboot neither disc can be seen. > Actually I don't think there is anything you need to recover from. > You have set the partition type of sdb1 to LVM and that is what it > should be. That is assuming that you used sdb1 as PV and not sdb. But sdb1 had ALREADY been set up. Actually I had formatted it with ext3, then followed the howto (pvcreate, vgcreate, lvcreate, mount) to set up LVM and then copied all my old data over. So I then set the partition type to LVM on a disc that already was set up with a VG, LV. ...now vgdisplay gives me $ vgdisplay Couldn't find device with uuid 'ZHl4Ak-mGS4-wFlF-4neF-G1Ed-GxWB-C4Smj6'. Couldn't find all physical volumes for volume group media_vg. Couldn't find device with uuid 'ZHl4Ak-mGS4-wFlF-4neF-G1Ed-GxWB-C4Smj6'. Couldn't find all physical volumes for volume group media_vg. Volume group "media_vg" doesn't exist ...but pvdisplay gives me encouraging news. I just don't know what to do with this information to try to recover. $ pvdisplay Couldn't find device with uuid 'ZHl4Ak-mGS4-wFlF-4neF-G1Ed-GxWB-C4Smj6'. --- Physical volume --- PV Name /dev/sdb1 VG Name media_vg PV Size 233.75 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 59841 Free PE 193 Allocated PE 59648 PV UUID rlnV4y-B4eJ-Pyc0-RLJm-2Zbv-t04C-dxzU1A --- Physical volume --- PV Name unknown device VG Name media_vg PV Size 186.30 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 47694 Free PE 47694 Allocated PE 0 PV UUID ZHl4Ak-mGS4-wFlF-4neF-G1Ed-GxWB-C4Smj6
