Reinstall CEPH on Proxmox 6

[AngryAdm]

True. I meant a more improved version of the pveceph purge is available in Proxmox VE 6.2.

You improved it even more in version 7. So when you run pveceph purge on node #6 the configuration vanishes from all other nodes, essentielly destroying our ceph cluster.. I clap my hands at such excellent software behaviour!

Worst of all, after having done that, guess what... the problem that arose... is THIS THREAD all over again 1½ years later. When can we expect this to be fixed?

You run a purge and it purged, wouldn't call that unexpected.. In general I'd recommend having backups also of configurations.

In pve7, this is the script I was able to use to reinstall ceph without issue:

systemctl restart pvestatd
rm -rf /etc/systemd/system/ceph*
killall -9 ceph-mon ceph-mgr ceph-mds
rm -rf /etc/ceph /etc/pve/ceph.conf /etc/pve/priv/ceph* /var/lib/ceph
pveceph purge
systemctl restart pvestatd
apt purge ceph-mon ceph-osd ceph-mgr ceph-mds
systemctl restart pvestatd
rm /etc/init.d/ceph
for i in $(apt search ceph | grep installed | awk -F/ '{print $1}'); do apt reinstall $i; done
dpkg-reconfigure ceph-base
dpkg-reconfigure ceph-mds
dpkg-reconfigure ceph-common
dpkg-reconfigure ceph-fuse
for i in $(apt search ceph | grep installed | awk -F/ '{print $1}'); do apt reinstall $i; done
systemctl restart pvestatd
mkdir -p /etc/ceph
mkdir -p /var/lib/ceph/bootstrap-osd
mkdir -p /var/lib/ceph/mgr
mkdir -p /var/lib/ceph/mon
pveceph install
systemctl restart pvestatd
pveceph init
systemctl restart pvestatd

this worked for me thx
