Mirrored drive replacement faulted

OpenZFS
1

I have a small zpool of a pair of mirrored 4 TB drives. One of the drives had been accumulating errors so I bought a replacement and swapped it out. The new drive made some nasty sounds when it first booted up, but has been silent ever since. I told ZFS to replace the drive, then let the resilvering run overnight.

zpool replace -f westside 5616852388428375487 /dev/disk/by-id/ata-ST4000VN006-3CW104_ZW63JF1T

Unfortunately, the next day I ran a zpool status and discovered new errors.

Is this a situation where I give it one more try and hope it works? If so, how do I restart the process from here? Or should I just reach out to Seagate and get a replacement?

Replace the SATA cable first. If that doesn’t fix it, try plugging into a different SATA port. If you still get errors after that, RMA under warranty.
