Since upgrading to 6.9.2 I cannot spin down parity via GUI, as soon as I spin down it comes back up.
Apr 8 10:18:45 Tower emhttpd: spinning down /dev/sdf
Apr 8 10:18:58 Tower SAS Assist v0.85: Spinning down device /dev/sdf
Apr 8 10:18:58 Tower emhttpd: read SMART /dev/sdf
Revert to 6.9.1 issue no longer happens.
I can manually spin down the drive. All other array drives which are also SAS spin down fine.
root@Tower:~# sg_start -rp 3 /dev/sdf
root@Tower:~# sdparm -C sense /dev/sdf
/dev/sdf: SEAGATE ST4000NM0023 XMGJ
Additional sense: Standby condition activated by command
Also is it possible to get an updated version of smartctl added.
Will continue to do more testing.
