ElectricEel-24.10.0.2 installed Nov 24
data-pool = 2 mirrored VDevs with 2x6TB drives = 11TB total storage
boot-pool = Mirrored DogFish 64GB SSDs
My boot-pool devices are sde and sdf. sde has been steady but sdf has failed and been replaced four times. In each case, I’ve attempted to use Windows DISKPART to test the failed drive and found they could be read but no changes could be written to the disk. Got “access is denied” when attempting a CLEAN ALL but DELETE PARTITION responded successfully without actually removing the partition. Attempted to remove write protection but got an error doing that, too. So, clearly the drives had failed.
Disk writes appear to be consistent on both drives:
I’ve moved sdf to a different SATA port on the MOBO and replaced the SATA cable. So far, this has had no impact. The only other thing that has not been replaced is the power connection which is daisy chained from the other SSD and one of the drives in data-pool.
I know the DogFish SSDs are cheap and not recommended but I use the very same boot-pool configuration in two Proxmox nodes installed last year and have not had to replace a single drive.
Does anyone have any idea why the same device keeps failing?
