I had a hard drive failure of one of my drives in a RAIDZ pool. The other three drives are connected and online but proxmox displaying that the raid exists. Is there any way to bring the raid pool back? There is no raid array showing up in the zfs window in the proxmox webui. Any help would be greatly appreciated. I don't really know what logs would be helpful, so if you need anything just let me know the command and ill post the output.
 
heres the what the terminal shows, I removed the serial numbers from the output:
ARRAY-32TB-RAIDZ FAULTED corrupted data
raidz1-0 DEGRADED
ata-ST8000NT001-3LZ101 ONLINE
ata-ST8000NT001-3LZ101 UNAVAIL
ata-ST8000NT001-3LZ101 ONLINE
ata-ST8000NT001-3LZ101 ONLINE
 
Degraded mean that the pool works but it cannot provide the redundancy that it's supposed to. Did a cable get disconnected? Did the drive die? Did you accidentally disconnect the drive?
None of this is Proxmox specific and any other ZFS guide on the internet (about RAIDz1) and degraded pools will apply.

The drive died completely. I have tried to follow other guides without success. I am new to using zfs pools and dont really know where to look though.

in that case, replace the drive as various ZFS guides (for Linux) on the internet describe. The Proxmox software cannot fix hardware problem...
