Replacing bad drive backplanes with 3D printed brackets and cables
A ZFS pool became unstable with repeated read and write errors. It sometimes went offline because three drives were marked as failed.
The likely cause was poor contact in the , not clearly the drives themselves. The were removed and replaced with that hold HDDs in three 5.25-inch bays, using cables instead.
A temporary setup was used to repair the storage array, but it had to be stopped after the drives reached internal s in the 50s Celsius. Installing the new brackets was difficult, and the first mounting position pushed the drives too far forward, so the case doors could not close once the HDD cables were plugged in.
Key points
- The ZFS pool had constant read and write errors and sometimes went offline.
- Three drives were being marked as failed, but the suspected cause was bad .
- The were removed and replaced with plus cables.
- A temporary repair setup overheated the drives into the 50s Celsius.
- Drive and cable mattered because the case doors would not close when the drives sat too far forward.
