Hi all, I sought the web for the error " Failed to find physical volume "/dev/zd96p5"." but the closest discussion in the LVM archives I found was one of mine back in 2014 https://listman.redhat.com/archives/linux-lvm/2014-June/msg00016.html This time though it seems pvs fails to find the physical volume when lvmdiskscan does recognize it. Do I have to really upgrade lvm2 or is there another way to have pvs recognize the volume? root@server:/etc# lvm version LVM version: 2.02.133(2) (2015-10-30) Library version: 1.02.110 (2015-10-30) Driver version: 4.34.0 root@ server :/etc# lvmdiskscan -l WARNING: only considering LVM devices /dev/sda5 [ 74.05 GiB] LVM physical volume /dev/zd304p3 [ 19.00 GiB] LVM physical volume /dev/zd96p5 [ 1023.52 GiB] LVM physical volume * /dev/zd112p5 [ 1023.52 GiB] LVM physical volume* 0 LVM physical volume whole disks 4 LVM physical volumes root@ server :/etc# pvs -a /dev/zd96p5 Failed to find physical volume "/dev/zd96p5".
