I’ve tried two ZFS zpool setups on my quad sata nas. I’ve not updated the jmicron firmware since I’ve not read anything about positive changes after the firmware update.
-
raidz on all 4 disks. When doing a rsync to that zpool the disks would disconnect and I would have to reboot: zfs does not want to restore the zpool even when the disks come back online.
When I limited the rsync throughput to 30MB/s the disks were fine and would not disconnect. -
Now I’m testing a second setup. 2 mirror vdevs in one zpool. And I’ve already rsynced 200GB and the disks are just fine. I’ll update when something goes wrong.
edit: and the disks disconnected again after 302GB. It looked so good. I even upgraded debian while running the rsync and all went fine for a while.
Now updated jmicron fw to v8.1.3.6. Lets see how it holds up
edit2: disk gone again. @dominik how did you set up the hardware raid? If that is still stable I’d like to try it
edit3: found it: Setting up HARDWARE RAID with QUAD SATA-HAT (jms561 controller)
