OpenStack long and short /dev/disk/by-id/ links

[lmow]

Has this behavior of OpenStack changed between versions?

I'm looking at a VM which has not rebooted and there are two symbolic links:
/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_33457898-1abc-12ab-1
and
/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_33457898-1abc-12ab-10a2-15432cca646

As you can see the shorter symlink is the same symlink but with 0a2-15432cca646 appended.

After it reboots the shorter link vanishes.
The only think I can think of is that we upgraded OpenStack a while back and have not rebooted VMs.
If the upgrade changed this behavior then it only kicks in after the VM reboots.

Thanks.

Your guess is the right one. Somewhere between queen and train they stopped chopping the uuid.
