Couldn't find all physical volumes for volume group s0. Couldn't find device with uuid 'Tzx4n9-iA60-yu3U-9oRe-R0jh-RBb4-Sw8EmF'. Couldn't find all physical volumes for volume group s0. Volume group "s0" doesn't exist In this case, you can make the volume group consistent again with "--removemissing": [root ~]# vgreduce --removemissing s0 Couldn't find device with uuid 'Tzx4n9-iA60-yu3U-9oRe-R0jh-RBb4-Sw8EmF'. Couldn't find all physical volumes for volume group s0. Couldn't find device with uuid 'Tzx4n9-iA60-yu3U-9oRe-R0jh-RBb4-Sw8EmF'. Couldn't find all physical volumes for volume group s0. Couldn't find device with uuid 'Tzx4n9-iA60-yu3U-9oRe-R0jh-RBb4-Sw8EmF'. Wrote out consistent volume group s0 Be aware though that if the PV you want to remove was actually in use you risk loosing whatever data was stored on it by this method - if possible get the PV back on the system and use the normal vgreduce. If this doesn't help then it would be useful to know what versions of LVM2 and device-mapper you are using and what distribution this is on.
