Hello
I have a ZFS cluster on my Proxmox server. This morning during my visual inspection of the servers, two hard drives showed red in the bay.
Indeed ZFS sees the two disks as being out of service but... when I do a SMART test (short) on the disks, I have no error
I downloaded the test tool for Samsung hard drives, but it tells me that the condition of the drives is good...
Do you have any advice for investigating this problem?
THANKS
I have a ZFS cluster on my Proxmox server. This morning during my visual inspection of the servers, two hard drives showed red in the bay.
