Hi,

I have a one node ProxMox cluster on 6.4-14. Now I started the process of upgrading to 7.x, but the pve6to7 script threw some errors related to CEPH storage:
  • OSD count 0 < osd_pool_default_size 3
  • pg 1.0 is stuck inactive for 14m, current state unknown, last acting []
Since this is an one node machine, and I'm not learning about CEPH anyway and I'm not planning to add more nodes (this is pretty much my lab/dev machine), I don't think I need to have CEPH at all.

I guess at one time in the past I created a cluster in the web gui (I vaguely remember it). I was wondering if it would make sense to remove the clusterization (if that is a word), I kind of assume that was what activated CEPH? And then upgrade?
 
hi,

assume that was what activated CEPH
no, cluster does not activate ceph.

if you don't want the ceph, you can just disable/remove it from your /etc/pve/storage.cfg file.

was wondering if it would make sense to remove the clusterization (if that is a word)
you shouldn't have to remove it for the upgrade.

disabling the ceph storage should get rid of the errors outputted by the pve6to7 script.

hope this helps!

This is what my storage.cfg has:

dir: local
path /var/lib/vz
content iso,vztmpl,backup

lvmthin: local-lvm
thinpool data
vgname pve
content rootdir,images


No mention of CEPH?
