[SOLVED] Default pve size LVM 97% usage

[Haider Jarral]

I have a 4 node ceph cluster, on each node I see this consistently, The LVM under Disks shows its 97% used, should I be worried, should I increase this space, will it effect my data, can I resize it in production. I do not keep any disk or iso locally, all is stored on rbd and nfs.

Hi,
what is reported here is the free/used size in the volume group pve. You have three logical volumes in that group, namely data,root,swap which use up 97% of the size of the volume group. This doesn't mean that all of that space is used within the logical volumes. With df -h / you can check the usage inside root and if you go to the LVM-Thin tab, you should see the usage within data.

Thank you that makes sense.
