Labels can be one approach where you mount by disk label rather than device
Creating the volume with the label
# mkfs -t ext4 -L testvol /dev/vdb
/etc/fstab then contains
LABEL=testvol /mnt ext4 noatime,nodiratime,user_xattr0 0
You still need to be careful to not attach data disks
Yea, the configdrive is a non-issue for us since we don’t use those. The
multi-drive issue is the only one really affecting us. While removing the
second drive and reattaching it after boot is probably a good solution, I think
it’s likely the issue will come back after a hard reboot or migration
There is a small patch in the bug which resolves the config drive
ordering. Without that patch I don't know of any workaround. The
config drive will always end up first in the boot order and the
instance will always fail to boot in that situation.
For the multi-volume instances where the boot volu
Thank you, it indeed seems to be the same issue. I will be following this bug

have you found a way to circumvent the issue? Could it be as

There seems to be a broken series of patches related to virtio-scsi
that were backported to Ocata resulting in some unresolved virtio-scsi
drive ordering bugs. I see it primarily on virtio-scsi based instanc
Hi,
Lately, we’ve been converting our VMs block devices (cinder block devices) to
use the virtio-scsi driver instead of virtio-blk by modifying the database.
This works great, however, we’ve run into an issue with an instance that has
more than one drive. Essentially, the root device has addres
Hello ops,
we have this working for Nova ephemeral images already, but Cinder did
not implement this spec:

Is anyone carrying an unmerged patch that implements this spec ?
I could not believe my
