In the meantime my BTRFS cache pool died and another reboot seems to solved the ZFS issue. Now thinking if i want to fix the cache or reinstall it as a new ZFS pool.

Hi, I've upgrade my Unraid OS to 6.12.3 from 6.10.3. Tried to import my existing ZFS pool and getting - Unmountable: Unsupported or no file system Zpool is alive and well: # zpool status pool: SSD state: ONLINE scan: scrub repaired 0B in 00:02:51 with 0 errors on Tue Aug 8 00:15:09 2023 config: NAME STATE READ WRITE CKSUM SSD ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 nvme-KXG50PNV2T04_TOSHIBA_************ ONLINE 0 0 0 nvme-KXG50PNV2T04_TOSHIBA_************ ONLINE 0 0 0 nvme-KXG50PNV2T04_TOSHIBA_************ ONLINE 0 0 0 errors: No known data errors Any ideas?

The moment i sent the replay i figured it out, it was the autofan plugin, for testing reason i configured it check temp every minute and for some reason it need to spin up the drives to check the temp in SAS, i excluded the SAS drives from the plugin and now it's working Thanks!

Between 20 seconds to a minutes Yes, happens both manually and after Unraid spin down delay. IT's movies so don't see a reason for frequent I/O... Not yet Reboot didn't solved it as well, don't think it's the plugin, but you have experience supporting people so thought you might seen this behavior before.

Hi Doron (from Israel?), it's only the SAS drives, SATA drives stays spun down. Also cleared statistic and in some of them there was no traffic and it's still up. It's not the dockers (only cache drive and disabled it for testing), will try a reboot later today.

The plugin spin down the SAS drive but after that i get a SMART read which spin it back up: Apr 27 23:06:15 Tower-Oron emhttpd: spinning down /dev/sdb Apr 27 23:06:16 Tower-Oron SAS Assist v0.86: Spinning down device /dev/sdb Apr 27 23:07:23 Tower-Oron emhttpd: read SMART /dev/sdb What am i missing? Unraid 6.9.2, HGST SAS drives and LSI SAS2008 HBA
