Just a matter of time Recently I started to receive notifications from FreeNAS indicating smart errors on one my hard drives. A quick check of the system log confirms a number of smart errors on /dev/da4.
root@freenas:/var/log # grep smart /var/log/messages Feb 1 03:39:51 freenas smartd[2739]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 1 03:39:51 freenas smartd[2739]: Device: /dev/da4 [SAT], Self-Test Log error count increased from 0 to 1 Feb 4 21:46:05 freenas smartd[48304]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 4 21:46:05 freenas smartd[48304]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 4 21:47:00 freenas smartd[48927]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 4 21:47:00 freenas smartd[48927]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 5 06:17:00 freenas smartd[48927]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 5 06:17:00 freenas smartd[48927]: Device: /dev/da4 [SAT], Self-Test Log error count increased from 1 to 2 Feb 5 06:17:00 freenas smartd[48927]: Device: /dev/da4 [SAT], previous self-test completed with error (read test element) Feb 5 06:17:00 freenas smartd[48927]: Device: /dev/da4 [SAT], Self-Test Log error count increased from 1 to 2 Pulling up the smart information available for /dev/da4 confirms the recent read errors.
Read through the preamble to see what I tried first and why it didn’t work. Or jump ahead to the working install method.
Preamble I’ve been using FreeNAS for a couple of months now, starting with version 9 and later upgrading to version 11. While the experience so far has been great there are a few glaring omissions. First and foremost “monitoring”. There is just no convenient way to monitor the system externally.
I run Plex media server in a FreeBSD based jail. Until now, to connect to the Plex system I would first ssh to the host system. Then I would run jls to find the jid of the jail.
# jls JID IP Address Hostname Path 1 - plex /mnt/vol1/jails/plex I could then connect to the jail system by passing the jid as an argument to jexec with the shell to execute.
