Unable to Mount Volume

[Play3r]

Hello

Recently i had an alert from freenas 9.1 that a disk hard either fail or dropped off and had a degraded status on the volume. Not really knowing which disk had failed or how to actually check through shell, I shutdown freenas and pulled out this disk I thought had failed checked it s.m.a.r.t status on crystaldiskmark, the drive showed that it was in Good Health status. Before placing the Hard Drive back in the server i booting it up missing the disk i had removed, freenas showed that the zfs status was unknown and I could not access the shares. I shutdown the server placed the disk back in so that all disks were now back in the server and booted it up.

Watching the server bootup, I saw the error "volume unable to mount i/o error"

I have checked the s.m.a.r.t status of all the drive and it all seems to be coming back ok

This is what i get when use zpool import

Can you post your hardware specs? Anything else that the server has done that is out of the ordinary? Were you getting nightly emails? If so, when did your problems begin?

If you aren't using ECC RAM, I'd do a RAM test before you go anywhere else just to make sure your computer isn't losing its mind. I use www.memtest.org. 3 passes without errors is a sign of good RAM. Typically this takes 1-12 hours depending on how much RAM you have. Normally I start it and go to bed.

Running a HP N40L G7 Microserver with 16GB of Kingston Hyper-X Genisis 1600MHZ 1.35v
5 3TB Seagate Barracuda's
Raid Z1

Running a memtest now, will see what comes back!

I currently didnt have any reporting setup as i logged into the box most days to check out what was going on, in hindsight I should probably set it up though. But no problems at all until now, I did installed the 16GB of Ram about a month ago and before that I had 4GB of ECC RAM (comes bundled with Microservers (I have 2) in itand have been running the box for about 6 months.

Scrubbing and Snapshots were setup

Memtest has come back with no error from 5 passes. Anything else to look at?

So got home today and decided to stop memtest as it was up to the 9th pass and rebooted the server, just to see if anything was different and well its working, everything mounted and everything is in tact, I dont even understand computers

Ya, computers are kinda like women sometimes. And I've been married for over 20 years. ;)
