It has 2 disks, the one named sdb is where ovirt node has been installed. The one named sda is where I configured gluster though the wizard, configuring the 3 volumes for engine, vm, data The filter that you do have in the 4.4.2 screenshot should correspond to > your root pv, > you can confirm that by doing (replace the pv-uuid with the one from your > filter): > > #udevadm info > /dev/disk/by-id/lvm-pv-uuid-DXgufc-7riC-TqhU-f8yH-EfZt-ivvH-TVcnEQ > P: > /devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sda/sda2 > N: sda2 > S: disk/by-id/ata-QEMU_HARDDISK_QM00003-part2 > S: disk/by-id/lvm-pv-uuid-DXgufc-7riC-TqhU-f8yH-EfZt-ivvH-TVcnEQ > > In this case sda2 is the partition of the root-lv shown by lsblk. > Yes it is so. Of course it works only in 4.4.0. In 4.4.2 there is no special file created of type /dev/disk/by-id/.... See here for udevadm command on 4.4.0 that shows sdb3 that is the partition corresponding to PV of root disk https://drive.google.com/file/d/1-bsa0BLNHINFs48X8LGUafjFnUGPCsCH/view?us... > Can you give the output of lsblk on your node? > Here lsblk as seen by 4.4.0 with gluster volumes on sda: https://drive.google.com/file/d/1Czx28YKttmO6f6ldqW7TmxV9SNWzZKSQ/view?us...

And here from 4.4.2 emergency mode, where I have to use the path /boot/ovirt-node-ng-4.4.2-0..../initramfs-.... because no initrd file in /boot (in screenshot you also see output of "ll /boot) https://drive.google.com/file/d/1ilZ-_GKBtkYjJX-nRTybYihL9uXBJ0da/view?us... > We have the following tool on the hosts > # vdsm-tool config-lvm-filter -y > it only sets the filter for local lvm devices, this is run as part of > deployment and upgrade when done from > the engine. > > If you have other volumes which have to be mounted as part of your startup > then you should add their uuids to the filter as well. > I didn't anything special in 4.4.0: I installed node on the intended disk, that was seen as sdb and then through the single node hci wizard I configured the gluster volumes on sda Any suggestion on what to do on 4.4.2 initrd or running correct dracut command from 4.4.0 to correct initramfs of 4.4.2? BTW: could in the mean time if necessary also boot from 4.4.0 and let it go with engine in 4.4.2? Thanks, Gianluca
