Volume shows "Error getting available space"...

[Richelieu]

Background: System has been running great for last year+. Last 3 months or so, had intermittent problems with the machine just powering down. Typically during writes to the array. (If I did read only operations, watching movies, etc, I could go for weeks without a power down) Just would take a power up and the system would be back and running...

Today it was different. I powered up the machine after it had been down for a couple days (I was busy!) and it booted up, but no array to be found. It shows the volume name "HD" and it shows all of the disks (all 6 are there) but no volume.

System: Gigabyte mobo (don't have specifics on which one, I'd have to go hunting), Highpoint 2755 RAID card (I believe 2755.. shows up as 27xx in FreeNAS), 16 gigs of Non-ECC RAM, 60 GB SSD as my boot drive. 6x4TB Seagate ST4000VN000 drives. No encryption, no fancy add ons... just RAIDz2 (4 drives data, 2 drives parity) and was running PLEX jail to stream my HD video. All 6 drives were SMART scanned and all of them come up clean. Oh yeah, running 9.3-STABLE.

Problem:
After doing searches and what not, I get the feeling I _could_ do some sort of export of the volume data and then reinstall FreeNAS on the SSD drive and then import the volume. I'm just not sure A) how to put that all together and B) with the volume data missing and not showing up, how would exporting get me anywhere? I have an export of the db for my system, but again, not sure if that'll help me.

Most of the search results have been someone using encryption on drives, or adding/replacing a drive, or running out of space because they put their OS on the RAID itself.

Thoughts? I really would like to not lose multiple TB of data...

Thanks,
Rich

lol another highpoint card. This is probably not going to end well for you. With FreeNAS you should not use a RAID card because it hides the disks from zfs.

what is the output of zpool import?

The highpoint card is merely being used as an 8 port SATA device. I don't have any of the RAID functionality enabled. I realize that the Highpoint cards are notorious for having problems, but they're also an affordable solution for adding multiple ports... I had this running for at least a couple years so I felt it was a decently solid system.

I haven't done the zpool import yet. I've seen several different zpool import commands during my searches... Is there one I should be doing, and what should I be looking for?

I have noticed that my jails are missing (though the windows share is still active)... I'd assume the jail disappears when the volume disappears? (which would then make me ask, why didn't the share disappear?)

I'm hoping there's a way to somehow "rebuild" whatever is missing. The data hasn't been touched on the drives (not by me at least, though I can't say the same for FreeNAS and/or the Highpoint card deciding to write over the disks willy-nilly) so I had hoped that somehow I could recreate the structure to get the data back.. or at least some of it.

I'll try again, what is the output of 'zpool import' and also 'zpool status'?

Is your pool actually working and shows up in the GUI? Your last post makes it sound like that.

Highpoint cards are not a good budget option. They are very bad for zfs and the recommended option is usually cheaper than your Highpoinr.

Back when I built this system, Highpoints were in the $150's, everything else was $300-400+... so the budget at the time for 8 SATA ports... was that... I realize I was taking a risk... and still am until I upgrade the card... I'll leave it at that.

Watching the boot up this evening when I got home, I noticed it said there was an I/O issue and I should "zpool import -F HD" (HD is my volume name) which it did successfully and a zpool status then showed it was rebuilding/resilvering... It went for about 30-45 minutes here, and then the system just shut down. I wasn't able to see anything else on the screen prior to it shutting down...

So I still have system issues, it's probably card related given it was doing it's cleanup work at the time.. so my upgrade may be coming sooner than later. I wasn't able to access the drive itself... the share still says it was offline... but the WebGUI was at least reporting the drive there with a valid file size and the jails present again, rather than the complete nothingness before... so it moved me forward.

Due to the SW nature of FreeNAS, I really just need 8 ports of SATA, correct? I'll probably go with whatever is recommended, but honestly that's what I'm needing, is always on SATA connections... (or in my case, 6 SATA connections due to 6 drives...)

Thanks!

Whatever dude you're not going to get help if you can't follow directions. I now see why you used an unsupported card, Later.

 

[Mirfster]

Only shot you have is to get those drives off of that Highpoint card and onto SATA Ports or a supported HBA; then try again.

Not real idea of your actual system specs (which would help); so shooting in the dark here...

Sounds like fundamental hardware issues causing system shutdown, perhaps flaky PSU or mobo ... probably nothing to do with the HighPoint card.

Last 3 months or so, had intermittent problems with the machine just powering down. Typically during writes to the array.
