So in looking at the messages log. I see the following
Code:
Aug  5 09:36:52 freenas smartd[25766]: Device: /dev/ada1, 2 Currently unreadable (pending) sectors
Aug  5 09:36:52 freenas smartd[25766]: Device: /dev/ada1, 2 Offline uncorrectable sectors

But my zpool status shows
Code:
pool: tbone
 state: ONLINE
  scan: scrub repaired 0 in 4h27m with 0 errors on Sun Jul 21 05:27:11 2013

errors: No known data errors

So are these errors just false reports? Would a scrub of the volume possibly fix this?
The disk 1 and 2 for whatever reason show up as multipaths for some reason or another
Code:
freenas# gmultipath status
           Name    Status  Components
multipath/disk2  DEGRADED  ada1 (ACTIVE)
multipath/disk1  DEGRADED  ada3 (ACTIVE)

I don't know why they show up as multipath and I can't access the tab in the gui for the multipath because it just loads a blank page.
I'm currently using Freenas 8.3.1-RELEASE-p2-x64
Thank you all in advance for your help with this.

Both Current Pending Sector counts above zero and Offline Uncorrectable Sectors are signs of a hard disk that is starting to go bad. Both of those are for the entire disk's surface while a zpool scrub only accounts for currently used disk space.

What you can do is run a long SMART test using smartctl to see if the disk passes. If it passes then you can safely ignore the errors. But you need to watch that value closely. If it starts going up you should seriously consider a disk replacement soon. Considering that you are using a RAIDZ1 and not a RAIDZ2 I'd replace the disks now unless you want to risk data corruption later. RAID5(and RAIDZ1) can't repair from more than 1 disk being missing or corrupted. In your case, you have 1 disk that has started showing signs of failing.

Post the output of the command smartctl -a -q noserial /dev/adaX, substituting X with all of your disk numbers. Please put it in CODE or attach it as a text file.

If you haven't read about RAID5 being dead years ago, you should read the link in my signature. You're kind of in a bad place since you went with only single disk redundancy.

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

I decided to go with the raid5 since my last config was setup that way. In the future I"ll have to get an external drive to backup everything to when I prepare to rebuild the pool to raid6 but that will be a bit. At least for now my drives are still under warranty but I'll have to figure out exactly which disk this is since it is part of the multipath I'm not exactly sure of the SN for the failing drive. Thank you for the help with this and it looks like from the way my smart output reads it might be time to go to WD and order the replacement drive.

ada1 seems to be quite old(10 hours short of 20k hours poweron time), failing short offline tests for quite some time, since at least 1000 poweron hours ago(if the server is on 24x7 then at least 40 days ago). I'd seriously consider replacing that disk now. If you had a RAIDZ2 I'd say you could wait for more problems, but with it failing short offline tests you should preemptively replace it. If a second disk fails before you replace this one you can kiss data goodbye...

You can see the serial number for ada1 by doing smartctl -a /dev/ada1 | grep serial.

If you post the output of your other disks I can tell you how those are doing...

I've replaced just about all of the disks in the array. I think that purchasing the WD Green Caviar drives was a poor choice initally. I'm working on replacing them with the WD NAS Red drives but just haven't had the funds as of yet to replace them so I keep RMA the drives as they fail.
Thanks for the serial command. Got the new disk ordered. I've also put in spin down values so the drives should be going to sleep in a few days I hope once Crashplan finishes validating my full restore.

Are you kidding? I have 24 of those Green drives in my server and they have been amazing drives! You do need to use the wdidle because if you aren't using them in a desktop you'll wear them out prematurely.

The Reds seem to be identical to the Greens except they have the wdidle setting disabled and have a longer warranty.

I will warn you that an aggressive spindown on your hard drives does wear them out faster than leaving them on 24x7. It's a personal choice whether you want to pay for RMAs(and replacement drives after the warranty expires) or pay for the extra electricity. I stick to leaving the drives on 24x7.

ada0 looks good, but is 41C. 30-39C provides the longest lifespan. The other drives look fine.

Cool thanks for the input on the green drives. I'll go look up the information for the wdidle to help with that. Thanks.

Hey cyberjack,

Do you have any concerns about using this method to disable the wdidle? Also I'll be sticking the iso on a USB stick rather than a cd since my server doesn't have a cd drive :). Thanks

Looks okay to me. You know you can't copy an ISO file to a USB stick and expect it to boot, right?

Yep :) was planning on using unetbootin unless you have any other recommendations?

Never tried unetbootin, but I have heard it will do ISO mounting. Another easy option(and what I use with about 20 ISOs on my 64GB memory stick) is RMPREPUSB. It uses GRUB4DOS and is easy to learn and manage.

Well I got the new replacement drive in. I had that drive mismatch error (I'll have to find the forum post that cyberjock replied on about it) But the drive is in the process of being replaced right now so at sometime tonight the new 2TB drive will be online and I can swap out.

I attempted to upgrade to 9.1 the other day through the GUI thinking that my USB thumb had the capacity to do it. It failed so I just ignored it. Well apparently it didn't totally fail.

During the drive replacement when I went to go pull the old drive out of the system, the system did a kernel panic. So I put the old drive back in and loaded the new drive into an empty bay. I then started the system back up. During the 1st boot it hung for a little bit and then rebooted. When it rebooted the 2nd time it came back up.

Went back up to my office to go log into the GUI and low and behold I'm now on 9.1. Wasn't really expecting this today so I'm off now to go read through the docs about how plugins and jails work in 9.1 so I can get my plugins back up and running. So far though I do like this new version of FreeNas and I'm glad that I can finally dismiss an alert that I can't do anything about lol.
