    Persistent Storage für Docker VM mounten?

    Hey allerseits! Ich bin noch etwas neu bei der Sache, und dementsprechend manchmal etwas überfordert wenn es um das ein oder andere Thema geht, als kleiner disclaimer. Nachdem darauf verwiesen wird, dass man eher VMs anstatt LXCs für docker container benutzen soll, würde ich gerne eine CouchDB...

    ZFS vs RAM?

    I have a 64GB RAM system with 16TB in a RAID HHD storage, so with 8TB used. The OS and VM/CTs are all in a 2TB SSD drive. Proxmox is set-up to use ZFS and I've noticed that my system has been peaking the memory usage, even though individually the services don't even use 25%. I've also noticed...

    USB Drive disappears from lsblk after a few days

    I have a 240GB SSD drive which is connected via USB. After plugging it in, the drive initally shows up correctly in lsblk and fdisk -l, and I am able to mount it without problem on the Proxmox host. The problem is that the drive seems to disappear from the host after a couple of days, and this...

    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

    [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.

    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.
