    Installation File System Options

    Wasn't the case in the past, but is it possible these days to install Proxmox directly (not on top of Debian) without committing the entire physical disk to that filesystem (as I recall, had to be ZFS)? TIA

    Hello, I am digging up a old subject : Deleting properly a FileSystem. I know that there is a very similar subjet here but the solution is for a Datastore not for a FS. I am unable to recreate a FS with the same name of a FS that I have previously deleted. Here is the full procedure : # List...

  8. [SOLVED] ZFS raid1 with VM-disk filesystem question

    Proxmox is using a ZFS raid1 storage. On there, a disk has been created for a VM. This disk is currently formatted as ext4. Does that make sense? I guess its up to me. I'm just double checking. I might format the disk to ZFS, since it has the ability to check integrity.

  12. Share a virtual drive amongst multiple VMs?

    I'd like to create a virtual hard drive and mount it to multiple VMs, some with read-only access. I do not want to share anything with the host and do not want to use networking to accomplish this. Is this something that's possible? Thanks.
