pmxcfs + qcow2

[alma21]

Hi,

there are often discussions regarding the usage of (non supported) ocfs2/gfs2 clustered filesystems with qcow2 (for thin provisioning and snapshots) on shared block storage. Would it not be feasible to use maybe an (extended) version of the internal Proxmox pmxcfs as cluster FS for VM disks ?

At first glance this sounds feasible, yet the design specifications are only for very small files and have different design goals in mind. The proxmox cluster filesystem is not designed for VMs, is backed by a sqlite database and uses the distributed shared storage paradigm, whereare ocfs2/gfs2 use the dedicated shared storage paradigma and both are not interchangable. If you want a similar filesystem to the proxmox cluster filesystem for VMs, have a look at GlusterFS.

But gluster is EOL,or soon to be, just so you know it.
