Hi Ethan,
Thanks for the offer. We have already thoroughly tested against version 8 and have migrated multiple pools successfully. All of which are stable. A few tweaks were made to our packages to be compatible with version 8. Make sure to use the latest packages (following the steps in the above post and running the reinstsall_nosan_after_dom0_upgrade script will ensure that the latest versions are installed)

Good luck with your migration.

I was following these upgrade steps, had my master upgrade from 7.6 to 8.0,
and now the following iscsi-cfg commands are not working and drbd shows "secondary/secondary":

iscsi-cfg become-primary
iscsi-cfg become-secondary

Also got this message on the upgraded box:

Did you run this script on the upgraded host?
halizard.org/release/misc/reinstsall_nosan_after_dom0_upgrade

The upgrade process would have removed some packages that are required.. After a major version upgrade, the above script should be run on the upgraded host to restore it back to its original state.

Some hard boots and constant fiddling later I ended up just upgrading the 2nd box as if the DRBD had resynced and iscsi was working though it wasn't and then did troubleshooting from there. Discovered an issue with the kernel upgrade that was causing jumbo frames to get dropped...
