Daily/Weekly Maintenance

[Andrew076]

I recently setup a FreeNAS server and I it appears to be running well. I have copied about 500 GB worth of pictures on it as a starting point to verify setup etc.

I have setup and started the CrashPlan plugin and it is currently backing up the pictures (although it says it is going to take 30 days to complete...)

I mirrored the USB boot drives and have the most recent version of FreeNAS running.

So, my question is what, if anything, is recommended to run in the background or check the disks etc. Something is already happening as I get an e-mail at 3:00 in the morning every day.

Thanks

you shouldn't get an email every day what exactly does the email say. Some other things that you can configure are short smart tests and long smart tests as well as a scrub but I think this scrub is already configured properly.

Some other things that you can should configure are short smart tests and long smart tests as well as a scrub but I think this scrub is already configured properly.

Fixed that for you. OP, there isn't anything you need to manually do on any sort of periodic schedule, but you should definitely enable the SMART service, set an email address in that service, and set up regular short and long tests (I do short daily and long weekly; others may vary, but at a bare minimum you'd want a long SMART test monthly). When you set up your pool, FreeNAS should have automatically scheduled a scrub every 35 days. I prefer a bit more often than that, so I've set mine to every two weeks.

Older versions of FreeNAS sent a daily status email, but 9.2+ have done away with that. If you're getting an email, it's because your system thinks there's something out of the ordinary going on.

That could be. I just assumed because I got a message every day. The first few messages were the same telling me about an update that I didn't install till yesterday (I needed a new keyboard for the boot to go through and didn't want to take it from my desktop): (see below)

A new update is available for the FreeNAS-9.3-STABLE train.
Changelog:
#6323 Bug Normal Group Ownership does not resolve from "account unknown"
#6723 Bug Normal Fix Samba SID generation with group mappings
#8828 Bug Normal Service WebDAV/apache24 unable to start due to syntax error
#8953 Bug Normal SMART errors now generate Alerts
#9149 Bug Normal API request for invalid values should return HTTP 409
#9150 Bug Normal Document iscsi_target_extent_xen field in API docs
#9182 Bug Normal High Point driver update which provides better 4Kn drive support and exposes more disk details

Then I got a new e-mail last night - which concerned me on the data as I didn't understand it all but it appears to be as a result of the update?

I will do a search on how to do a Smart Test...

OK, the first is a normal update notification--the system will notify you daily about available updates. The second is normal when you reboot the system (which is, or at least has been, necessary when you update).

Setting up SMART tests is discussed in the manual at http://doc.freenas.org/9.3/freenas_tasks.html#s-m-a-r-t-tests.
