I can see in file /etc/lvm/backup/vg_devserver that the lv_root LV has been extended by a mere 32 Megabytes (yes, Mega) on the missing physical volume. Do you still have the additional disk? The best thing to do would be to put it back, make a partition on it, and then re-create the missing PV. I'll assume that the new partition is /dev/sdb1. Adjust all references in the following if it si something else. Make a copy of /etc/lvm/backup/vg_devserver on vg_devserver.bak, and then run pvcreate -v --restorefile vg_devserver.bak \ --uuid "vSbuSJ-o1Kh-N3ur-JYkM-Ktr4-WEO2-JWe2wS" \ /dev/sdb1 (I've broken that up into multiple lines to avoid word wrap problems.) You should then be able to run pvs and lvs successfully. To properly remove this PV from the LVM structure, run lvreduce --extents -8 /dev/vg_devserver/lv_root vgreduce vg_devserver /dev/sdb1 pvremove /dev/sdb1 That lvreduce will get rid of the 32MB that were allocated on that added PV. You will probably get a warning about possible data loss and will have to confirm. The vgreduce and pvremove should then proceed without any issues. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.
