Hello,
We using a proxmox cluster consisting of several nodes, which uses HA and CephFS for most of the VMs. Also, we use an off-site proxmox backup server and since local backups are faster reloaded after configuration mistakes, we also want to keep daily backups stored locally on the respective nodes where the VM is running on.
Since the local storage is by default only about 90 GB in size and our local backups exceed this limit and the local-lvm is barely used and thus wasted, we would like to shrink local-lvm and enlarge the local one.
We found the following threat related to this issue: https://forum.proxmox.com/threads/reduce-size-of-local-lvm.78676/
Since we are using proxmox HA cluster and thus all nodes posses a local-lvm, I wanted to ask if there are any troubles (like instability) coming into our direction, if we follow the following steps (hopefully without the need to reboot any hosts):
For each node:
1) Move all local VMs away to other nodes
2) # lvremove pve/data
3) # lvcreate -L 200G -ndata pve
4) # lvconvert --type thin-pool --poolmetadatasize 1G pve/data
5) # lvextend -l +100%FREE --resizefs pve/root
Thank you very much for your expertise on this subject.
