On upgrade, vol0 gets corrupted

[DRG]

Hello all. I'm having trouble upgrading the NetApp simulator on ESXi. Upgrading through the boot menu doesn't work at all, but uploading it as a second image then making it the default works at first, but errors out upon reboot with vol0 getting corrupted. Doing a simple 'vol show' at that point, OnTap comes back with "there is no 'show'". I should state that I increased the vol0 space before the upgrade and there was still 1G free after uploading the image.

I should also state this is a single-node cluster, and I do see "corrupted replicated database" errors on boot.

May be 1G is 'not enough' free space.

Like I said, 1G after the new image was uploaded

Before, after the upgrade reboot finished and everything looked good, I rebooted again. This time, after the first reboot and everything looked good, I accessed it through SSH and it said the upgrade was still in progress. I waited until I could SSH into the cluster without that message. 

I also made sure there was no volume-related jobs before the upgrade.

Everything is good.
