Community Forum > Encrypted Hot Spare

Hi,
We've set encryption on all drives and used few to create storage pools. The rest of the drives were marked as hot spares. We later failed one of the encrypted drive in the storage pool.Surprisingly none of the encrypted hot spare standing by was able to replace the failed disk. Replacement failed after multiple attempts by the system to use one of the spare to replace the failed encrypted disk.
We later decrypted one of the hot spare and re-ran the test. This time the unencrypted hot spare replaced the failed encrypted drive without issues. As you can imagine we ended up having a storage poolwith encrypted and non-encrpypted drives. That's not something we'd want in our environment.

Long story short, disk replacement failed when the spare disk is encrypted. Have you come accross this kind of situation? Or will you know a way to replace failed encrypted drive by encrypted hot spare ?

Hello Peter,

We have not yet run into the behavior you are describing.

We support the Encrypted Disk features with our Enterprise edition License keys. If you have an Gold or Platinum Enterprise level License, can you contact support@osnexus.com so that we can work with you further on this issue?

Thank You,

Hello Peter,

My engineers looked into the problem you reported.

We have determined that we do not currently support the Encrypted disks in our Hot Spare management for ZFS RAID at the Storage Pool level. We have engineers working on this and plan to have support for encrypted disks as hot spares in a near term release of QuantaStor.

Please keep an eye out on our change log at the following link to be notified when this improvement is available: http://wiki.osnexus.com/index.php?title=QuantaStor_Version_ChangeLog

Thank You,
