Is there any way to remove ZFS and Ceph, they cause errors and taint the kernel
https://itsfoss.com/linus-torvalds-zfs/
There isn't anything better than ZFS at the moment. Having a tainted kernel doesn't really mean much.
Except having slightly better deduplication, I don't the see what justifies the extra complexity and living under the bad aura of Oracle. LVM does almost everything ZFS does, it's just less abstracted, which I like actually because I want to know on what hard drive my stuff is, not some mushy file cloud that either all works or is all gone.
LVM is not even close
ZFS is way more fault tolerant and scalable due to the underlying design. In continually does data integrity checks and will catch but flips.
ZFS also has Arc which allows your ram to act as a full on cache which improves performance.
You can do data scrubbing with PAR2 or filesystem level with btrfs on top of LVM (or even in a traditionnal partition)
I think you can ram cache with bcachefs or a ramdrive, and unless you're in a VM then your file system driver would already do file caching in ram ?
Don' use bcachefs as it isn't stable and was removed from the kernel. As for btrfs it is still in technology preview on Proxmox isn't considered production ready.
I would just use ZFS. Don't reinvent the wheel.
Whilst on many things I respect Linus he is always opinionated to the max. I seem to remember him doing the same over hardware raid and then software raid as well over the years - so Linus what would you like us to use for some data security eh? I do have to throw in that this article is also from 2023 - a long time and a whole host of the issues he says are simply not true any longer
Ceph isn't installed by default (at least it hasn't been any time I've set up PVE) and there's no need to use ZFS if you don't want to. It's available, but you can go right ahead and install the system on LVM instead.
Well, it taints the kernel, probably runs some background processes, it should be removable ?
Tainted in that the kernel and ZFS have different licenses. Not a functional impairment. I have no way to check to check a system not using ZFS. For my use case, Debian plus ZFS are PVE’s principal features.
