I had proxmox 4.0 running for couple months then did apt-get update then upgrade to move to 4.1 proxmox. This is on Supermicro hardware with 3 sata drives using ZFS to do a RAID1 type setup. Everything seemed fine until I decided to reboot. No longer have access to server. Any idea what would cause that? I have 2 hour drive to server or fee for remote hands to find out more info. Nothing important on this server yet fortunately.
 
Apparently its a Kernel panic.

From cropped photo I have received.

1.926083] ---[ end Kernel panic - not syncing: VFS: Unable to mount root f -------------
on unknown-block(0,0)

This is on a Proxmox 4.0 install after updating to 4.1 and rebooting. Its installed on three 4TB sata drives with ZFS all 3 in a RAID 1 fashion.
 
Hi,
do you make a apt-get dist-upgrade or only apt-get upgrade?
because if you make make only an upgrade the you do not get the latest kernel.
 
apt-get upgrade only upgrade installed packages

apt-get dist-upgrade also install new packages from dependencies.

So you should always use dist-upgrade, or it could give you breakage like this.
 
Yes because you have now a new zfs package and an old kernel (exactly old zfs module).
And they are have to be the same version.

please use in future always dist-upgrade
 
I thought dist-upgrade was for moving from one major release to another. Would this only be necessary when moving from say 4.1 to 4.2 or something like that?

Well, that's true because debian/ubuntu never add new packages in a current release version.

Always use dist-upgrade with proxmox, because new packages can be included at any time.
