Cannot create new Device from ibvs Snapshot file for restore

[dr.action]

Greetings NC and Support Team,
I am trying to restore some single files from an "ibvss" Snapshot regarding the documentation "StarWind iSCSI SAN Software: Implementation of Enhanced Data Protection Using StarWind Snapshots" page 24 and following.
Creating a Device from a Snapshot runs into an error, here the Log entries:

There is indead no "snaps_00000002.ibvdb" file, only a file named "snaps.ibvdb". The same happens for other snapshot files too, e.g. "snaps_00000001.ibvdb"
What is going wrong here?
Thanks a lot for your help.

Could you please clarify what StaRWind version are you using?
And one additional thing that is need to be clarified for we to know what actions could be suggested and what are not - StaRWind is in production environment, correct?

Hello Anatoly,
thanks for answering.
I am evaluating Starwind v5.8.1907 and it is not in a production eviroment yet, only in our Lab.

I am trying to restore some single files from an "ibvss" Snapshot

There is indead no "snaps_00000002.ibvdb" file

Could you kindly clarify how are you trying to acomplish this if you haven`t got .ibvss file?

[dr.action]

???
I have ".ibvss" Files! As you can see in Log, i mount one of them.
Then i got the Error that a ".ibvdb" File is missing.

[Anatoly (staff)]

Deeply appologies! I`ve misread that!

1a.ibvdb - is the file that contains the data about the new snapshot, and it is creating during taking snapshots. Are you sure that noone deleted it?

[dr.action]

Absolutly sure!
I tried it several times and every time this File is missing.
I tried to delete the hole Device and create a new one - same Problem.
I tried it also with CDP Device with automatic Snapshot Funktion enabled - same Problem. Snapshots are creating but there is never a "*000000*.ibvdb" File.

Could you plrease try to create linked clone first and only after mount it?

[dr.action]

Creating a linked clone works.

What about the Documentation "StarWind iSCSI SAN Software: Implementation of Enhanced Data Protection Using StarWind Snapshots" page 24 and following?
Why is this not working?

Could you please clarify what exactly is not working?

Forget it

Dear dr.action. OK, since you have not specified your last question and your initial issue is solved I think I can close this thread.

Have a nice day!
