I just upgraded from 9.10 to 11.2 beta 2, and am also having a smartd error:
Oct 17 16:15:40 nas1 smartd[93413]: Unable to register ATA device /dev/ada0 at line 3 of file /usr/local/etc/smartd.conf
Oct 17 16:15:40 nas1 smartd[93413]: Unable to register device /dev/ada0 (no Directive -d removable). Exiting.
/dev/ada0 is my SSD L2ARC. I have edited the disk to disable SMART, but it doesn't make a difference. smartd still refuses to start, and still calls out that disk.
Known issue? I haven't rebooted after editing the disk's SMART flag, but it seems like that would be a bizarre requirement.
Edit: I also tried adding the "-d removable" option under disk edit, but that had no effect, too. The UI links to the
smartctl manpage, but I noticed the removable flag is not mentioned.
Edit 2: as mentioned in an earlier post, I tried adding that SMART option with SMART both enabled *and* disabled for that disk. No difference.
