Wiped 4.x installing 5.1 errors out

[Cronus89]

Setup a zfs raid6 on 4x1TB drives on Proxmox 4.x, 2 were replaced with 2TB drives. I wiped this server now and am now trying to install with 4x2TB Drives (2 of those from the previous install.

I am having issues and it errors out when its done with unable to unmount zfs, I talked on the IRC Channel on Freenode, and we figured I need to zero the start and end of the disk, no luck... So over the weekend I decided to zero the entire disks, all 4. Still same error... Attached is screenshot.

please post the full debug log (found in /tmp/install.log via the debug shell)

 

[Cronus89]

How do I get to the debug shell? It's still sitting on the same screen in the screenshot. CTRL C etc does nothing.

 

[Cronus89]

Figured it out, Debug mode as you boot the installer, (2nd choice)

Attached is install.log

 

[fabian]

can you try booting with the "rescue mode" of the installer CD? if that succeeds, you can try installing grub to /dev/sda and /dev/sdb from within the booted system.

 

[Cronus89]

rescue doesnt work.

screenshot attached

 

[fabian]

does grub see all of your disks (when you are on the boot menu of the iso, press 'c' and then enter 'ls')?

 

[Cronus89]

It doesn't look like it does, screenshot attached.

 

[fabian]

then you need to find out why - check your bios settings.. does a regular LVM install work?

This server ran 4.4 fine. I killed it and 10 minutes later tried to install 5.1 with these errors

I'll try the 4.4 install tomorrow to verify it still works.

 

[Cronus89]

Finally got back to it, 4.4 fails to install now for the same reason.

 

[Cronus89]

Running 5.1-3 Installer and it installs fine if i choose ext4.

I'm trying a ZFS Raid1 and its working. Put it on two ssd's and gonna have the zfs raid10 as a datastore only.

As I've seen on this forum, its something to do with RAID10 not wanting to install.

 

[Cronus89]

Playing around, I was able to wipe and reinstall zfs raid 1 fine on the SSD's, but no matter what I did to the 4x4TB drives, be it zpool clearlabel etc, or even formatting them on windows... they wont work.

I was able to create a raid10 zfs manually once i booted off the raid1 ssd's

I am thinking it has somethign to do with the 4kn drives
