One node ProxMox, remove cluster

[littlebighuman]

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,

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!

Thanks I will try and report back.

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?

try:

apt purge ceph-mon ceph-osd ceph-mgr ceph-mds
rm /etc/pve/ceph.conf

That seemed to have done the trick, thanks. I'll go ahead with the update to 7
