[PVE-User] ZFS Storage Issue

[Sivakumar SARAVANAN]

Hello,

Thanks for the update.

Please find the below requested details.

1. I created the ZFS pool with 2 mirrored using HDD disk by mistake
(Actually I suppose to create a ZFS pool using the SSD disk)
2.  Noticed that I accidentally used two HDDs instead of using two SSDs
thatare also in the system.
3. Tried to create a new pool with the SSDs, but couldn't (for some
reason) , Because I can't see a free disk to create it.
4. Destroyed ZFS HDD pool with the destroy command, but still can'tcreate
the SSD pool.
5. I can't see any free disk to create it while creating the ZFS pool.

Mit freundlichen Grüßen / Best regards / Cordialement,

Sivakumar SARAVANAN
