Hey Vered,
IIUC the you have a self-created lvm, to which you're trying to
posix using ovirt. If that's the case please try to manually change the device's
connect as permissions
to 36:36 under /dev/<your_VG>. If that doesn't work try the actual device it's mapped to (which is what vdsm actually tries to mount). If that also doesn't work please send us the output of:
ls -lh /dev/<your_VG> .
Still failed mate after a chmod 36:36. The thing is though, it _does_ mount the device for a moment before failing and unmounting it... Is this the same behaviour as before?
[root@blade01 ~]# ls /dev/VolGroup/lv_images -lh lrwxrwxrwx 1 root root 7 Dec 15 16:52 /dev/VolGroup/lv_images -> ../dm-2
I see /dev/VolGroup/lv_images are still root:root. Please chown 36:36 as well.
Please state the all the chown you tried.
Possibly a starting point for automating LVM device permissions setting is https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm... and in particular the possibility to add, under /lib/udev/rules, a customized file based on the one found in /usr/share/doc/device-mapper/12-dm-permissions.rules Not tried myself though...
