Unable to Import zpool

[shetu]

My zfs pool gone after power failure. zpool import -f command result are same.

1. * FreeNAS version : FreeBSD 9.0-STABLE (revision 199506)
   
2. * Hardware: x86-embedded on Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz
   
3. * Motherboard (Model) : Gigabyte G41M-Combo
   
4. * CPU (Model)
   
5. * RAM Size (in GB and model) : DDR2 4GB
   
6. Hard Drives (Model), Quantity, and RAIDZ configuration : 1 Hdd 2 TB, stripe
   
7. Add-On cards : no add-on cards
   
8. For network connectivity, include details on your network hardware/configuration.

Yup, you had a single disk stripe and probably didn't have a UPS either. It's probably safe to say goodbye to whatever was on your pool. At this stage, you will need to restore from backup.

Yeah, if that was a single hard drive, without proper protection from power surges and losses, and you can't import, then you're more or less screwed sir.

This is why we have strict hardware and pool configuration recommendations.

Sorry to deliver the bad news.

Awww... You all ruined it. I wanted to see if they were running the same setup from: Freenas disappear from Lan

 

[shetu]

Is there any other way or I call hdd recovery option?

 

[DrKK]

HDD recovery on a 1-drive ZFS vdev is highly non-trivial, and I imagine, expensive.

I too, was waiting to hear the reply.

Last year the OP said "it is for learning purpose. I will move on real hardware when i finish learn freenas."

If it's the same VM with 512MB RAM, perhaps it should be nominated for a Darwin award.

Jesus.

Sometimes I wonder why I bother.

If it wasn't a VM, why would a power failure kill the pool?

In this case it looks like the last transaction that occurred didn't get fully committed to disk. Using the -f flag like it says will try to roll back to a good transaction state.

This person also has terrible hardware and probably lots of other problems.

That shouldn't be a big problem.

What model HDD would seem to be useful to know.

No, the -f flag will allow importing a pool that (it thinks) is in use on another system, i.e., that hasn't been properly exported. The -F flag will try to roll back to a good transaction state. The -F flag can be combined with -n to determine if the rollback will be possible without changing anything.

I stand corrected.
