Reporting of ZFS events and scrubbing

[Gruelius]

Hey Guys,

Two questions:

Is scrubbing scheduled automatically?

And is there a way to report on ZFS events? i noticed i can filter to system messages, i am more concerned about things like disk failure e.t.c


If noone can answer i can setup nas4free in a VM but id rather not.. i would have tested when i setup the array but i did that under freebsd a long while ago, not going to risk my data doing so haha!

Thanks

Is scrubbing scheduled automatically?

NO, but you can add a cron job to meet your req, somethig like

Code: Select all

zpool scrub /mnt/mypool 

once a week, once a month , etc...

PD: I suggest to do once a month or every 4 months, because scrub is really CPU and Disk intensive, and if you use your NAS in a small Office or in Home I suppose that you do not write GB of data all days, so to check 3 times a year can be good for this scenario.

I use a script to monitor the health of the disks, as well as carry out regular scrubbing. I run a scrub every Sunday morning with the zfs_scrub script, and then hourly check on the status of the pool with the zfs_status script. Both of my scripts are based on the ones found here:
Helpful Monitor Scripts

Additionally, I have setup SMART reporting that emails me when there is a hardware alert (high temp, etc).
