Did I just lose a drive?

So, I got a message this morning:

Am I correct in assuming that one of my hard drives in my FreeNAS box has died?

It has been removed from the pool for some reason. You'll have to do some basic troubleshooting.

• Does the drive have power?
• Have you tried replacing the SATA cable?
• Have you scheduled regular long/short SMART tests?

This morning when I went downstairs I did hear the machine beeping (It's an HP Z400), so I knew something wasn't right. Then I checked my email and had the message above.

Also on a side note, I can no longer log in to FreeNAS. When I try to pull it up by the static IP, I get an "connection refused" browser error. I can ping the static IP Address and get a reply, and I can still access all my data over a network share. Even if the drive had died, I should be able to still login to FreeNAS though, right? FreeNAS is installed on a thumb drive in the back of the machine.

You *should* be able to login, however my experience with these things, once a piece of hardware fails, both software and other hardware tends to "freak out". Whether it's a power supply or a kernel bug, I assume you're just using SATA so the entire system could've just locked itself up or the drive could be polluting the entire bus with garbage, crashing the OS etc.

I'd use a terminal to see what's going on and restart if necessary.

If a drive fails and disapears it takes the swap partition with it. If you had any active swap, the chances are your system will hard crash. Awesome.

Run this script on a cron to work around this issue: Script to pagein any used swap to prevent kernel crashes

So I rebooted the system last night, and I am able to login now without any problems. Also the beeping that the FreeNAS box was doing, has stopped. However, I still get an immediate email on boot that says :

Code:

The volume vol1 (ZFS) state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state.

Followed by;

So I'm not really sure how to check and see what exactly is happening. In FreeNAS the disks look like this:

Beeping is probably a hardware problem. It might be logged in the BIOS.

Quite likely a hard failure with that drive. You might want to do some troubleshooting:

But since you have a RAIDZ1 pool, you might want to just go ahead and replace it.
