when you edit /etc/pve/corosync.conf (in normal conditition, when you have quorum and write access to /etc/pve), the file is copied locally to each node in /etc/corosync/corosync.conf , then corosync is restarted.
if you have done change ip or...
The problem is, and I've read this somewhere else on the forums: that clustering only officially 100% works with nodes being on the same physical layer 2 network
since corosync 3.X, it's use unicast udp (before it was multicast), so it's...
can you try to add issue_discards=1 in lvm.conf ? (I'm sure it's working at lvremove , I don't known if it's mandatory when discard send by the guest os)
Do you have good performance with ocfs2 ? Each time I'm trying I have pretty bad...
It is as advanced option like for LVM, but for directory storages one can only set it when adding a new storage, not changing it for existing ones. IIRC this was done to avoid potential confusion with existing qcow2 volumes, which cannot happen...
another thing not yet implemented is thin provisioning, where it'll be possible to have a smaller lvm volume than the defined size, with auto-extend of lvm volume. So, currently, each snapshot use the same size than the base lvm volume
hi, I think that the option is not yet exposed in the gui,
but you need to add "external-snapshots 1" in lvm storage option in /etc/pve/storage.cfg
Then, create a lvm disk with qcow2 format (not sure the format is already exposed in the gui...
live migration with or without HA is exactly the same process. Personnally, I never had a single corruption in 15 year (with around 4000vms in production).
What is your shared storage ? same cpus on differents hosts ?
you really should use fleecing option in your backup advanced option. (you can use same ceph rbd storage than your main vm).
(btw, I hope than your cephfs storage for your backup is not in the same ceph cluster than your production rbd storage...
It's look like the initramfs don't have the virtio-scsi module. (I have seen this with some almalinux recently coming from vmwarre too)
maybe check this doc, it should work on proxmox too ...
It should be isolated without nat. The only way with nat without firewall could be to create vrf like for evpn zones, but It'll need some route leaks between main vrf , so I'm not sure it's reasy without a routing daemon like frr.
