We know that now oVirt doesn't make snapshot for direct lun.
Please consider this scenario:
I have a VM with total 2 disks: the os image disk is created on the nfs domain, while the
other one is a direct lun disk.
Now I'd like to create a snapshot,
1. should I remove the direct lun disk first, then make a snapshot?
2. If I don't remove the direct lun disk, oVirt will exclude it automatically, and
snapshot can also be created successfully. But I have no idea if this is supported by
oVirt, please anyone can make some comments?
Thanks much.

you don't need to remove, ovirt should exclude "unsnappable" disks
automatically, and direct LUN disks are "unsnappable". Regardless of this,
you can choose yourself which disks you include in a snapshot

Hi Benny,
Thank you so much for your quick response. Yes, oVirt indeed excludes direct luns.
I have one more question, does oVirt support "Making snapshot without removing direct
lun disks", I mean, is this a valid operation for oVirt?
Thank you,

I designed test cases to cover the scenario that making snapshots for disks including
direct luns, if it is not a valid operation for oVirt, I can remove these cases; If it is
valid, I will add more cases, including VM export. Thanks.
