PVE on ZFS not booting

[mhammett]

Dell OptiPlex 790 with four HDDs in a ZFS 10. I remember having difficulties when I first started in getting PVE to boot, but I must have solved them because I've been running for a while. I shut the system down and now I can't get it to successfully boot.

One drive says this: https://www.dropbox.com/s/mffp5mkqfduoz52/2015-09-10 15.51.40.jpg?dl=0

Loading Linux 2.6.32-39-pve ...
error: checksum verification failed.
Loading initial ramdisk ...
error: you need to load the kernel first.

The other three say this: https://www.dropbox.com/s/2ncyn6xjfbsir4o/2015-09-10 16.08.57.jpg?dl=0

Selected boot device failed.



I'm assuming this has something to do with the other three disks not setup (for whatever reason) to boot the system.

Ideas?

What about installing ProxMox to a USB stick and importing the ZFS pools on the existing disks? I know in my Nexenta setup, existing pools import rather flawlessly, but of course, I'd have to reconfigure the system unless someone knows a better way?

Having gotten nowhere with the existing install, I'm attempting to mount the previous zpool into the Proxmox now on USB stick. After some install issues (3.4 wouldn't install, had to install 3.3 and then upgrade) and then some rootdelay issues (I had to set it to 20 instead of the 10 I saw in other threads), I got it online... ish.

The zpools aren't matching in size and of course, the content I'm looking for isn't there. Help?

Any ideas?

Bueller? Bueller?

I'll try to help you...

so how many ZFS Pool did you created? Only the rpool or also another pool, only for the vm's?

 

[mhammett]

The entire system was on four discs in a single zpool (rpool). It was setup similarly to RAID 10 (I forget the order, but two sets of pools, each with two discs, stripped and mirrored).

 

[mhammett]

I guess I'll just wipe everything I've got on there and start over.
