Can't bring drive ONLINE from UNAVAIL

[eqartimus]

Ok, I have read sooooo much. I am willing to read more if you point me somewhere. I even found a few threads with this same title (very similar.) But I still can't resolve my situation.

I *think* i bumped the cable when I put the cover back on the case. The drive *disappeared*. I shutdown and changed the cable. Now the drive is *there*. But I am unable to Online it or whatever. I scrubbed it and I did Online it, but none of that changed the status of UNAVAIL.

So, should I just hit the "replace" button and see if it brings it back?

 

[cyberjock]

You can try doing a replace, but you're probably going to have to take the drive that isn't in the pool anymore and zero out the disk, THEN do a replace.

This is why you don't touch shit with the server on! LOL

 

[eqartimus]

Replace seems to have worked. I am going with the story that I bumped the cable. I have been reading non-stop for 2 weeks now (retired from CIS field 15 years ago) and still feel pretty much "in the woods" on this stuff.

I guess I will set up SMART drive test to run -- and verify that I have no actual drive problem. I have yet to see the output from these SMART tests. I am guessing that they are SMART enough to tell me if I need to know something :P

Thank you for your support cyber -- I watched your slide show .. it was nice to see things organized ...

 

[DrKK]

Sir:

If you have the SMART service set up in the GUI, it should email you with problems.

However, if you'd like, you can drop to the FreeNAS shell prompt, and do: smartctl -x /dev/adaN where N is the drive number, and you will see the full SMART output. Midway in that output will be the results of the last several SMART tests ("Completed without Error" is what you'll probably see since you didn't get an email).

Cyberjock and I recommend doing a "long" SMART test biweekly, and in the off weeks, that's when we schedule scrubs. On any given week, therefore, you should have either a scrub, or a "long" SMART test scheduled. You can configure these, I am sure as you know, in the GUI.

 

[eqartimus]

Thanks DrKK and Cyber ... I will set my machine as you suggest. I spent 30 years knowing everything about computers and after 15 years out of the field, I know next to nothing. (As Cyber warned) it has been steep learning curve ... and clearly, Im not even close to done. But it's really nice that you guys contribute your time and attention to the people here that need it. THANK YOU!
