Re: [ovirt-users] Disks Snapshot

*Are you talking about /dev/vgname/lvname link or the links under/run/vdsm/storage/domain/image/volume,or /rhev/data-center/pull/domain/image/volume?* in /rhev/data-center/pull/domain/image/volume */dev/vgname/lvname is created by udev rules when lv is activated or deactivated.To understand if this is the issue, can you show the output of:* *pvscan --cache* *return:* [root@srv-qemu02
