Possibly linuxBtrfs is a great filesystem for proxmox in raid 1. Stop telling people not to use it
AppoxoFor those without knowledge: Alternatives to BTRFS are what? EXT4 or NTFS?
Valon_BlueCorrect, btrfs is a filesystem format.
What are the alternatives to it? NTFS? EXT4? ExFAT? FAT32??
𝕽𝖚𝖆𝖎𝖉𝖍𝖗𝖎𝖌𝖍xfs. ext4 doesn’t have a comparable feature set, and nobody is going to use those others as their main filesystems on Linux. bcachefs will be a contender, once it’s included in the kernel, or if you’re the sort who compiles their own kernels.
poVoqThe only file-system that is somewhat comparable to btrfs is OpenZFS. Xfs isn’t.
Seems like zfs or btrfs?
At least I usually read about storage file system usually being ZFS by default.

jelloeater85ZFS has been around for a long time. Rock solid w RAID.
See FreeNAS. ZFS was orig on BSD but AFAIK got ported to Linux a while back.
It now TrueNAS and both freebsd and Linux use the same implementation (openzfs)
Yeah, zfs is what I meant. Or yfs, as in “Y-use anything but btr-FS?”
Mostly ZFS, XFS and ext4
GlarrfMy anecdotal experience with btrfs is that it constantly broke in raid 1, no problems with any other filesystems on the exact same hardware and setup. YMMV
How long ago was that? Modern btrfs is pretty stable.
Last year, unraid, identical SSDs. I changed so many sata and power cables, so many settings.
I love it for single drives, but for RAID, ZFS all the way.
ZFS also supports single drives, is there a reason to use btrfs instead?
IIRC it works with TimeShift, aka time machine for Linux.
Agreed, I switched over from OpenZFS to btrfs and while it does lack some more advanced features, using btrfs for raid1 disk pools has been a very solid and hassle free experience.
TCB13Yes BTRFS is really good and solid. Usually survives hardware failure much better than the EXT* crap.
I’ve used Proxmox in the past w it, worked okie. One crazy hypervisor. I mostly stick w VMware, it just works. My uptime is measured in years.
You can do the same thing with proxmox.
The benefit of proxmox is that it is libre and uses Linux components.
Well I’ll never get a uptime like they in proxmox cause I update.
It has been a while since I looked at it but does proxmox support HA replication using btrfs? From what I remember only zfs worked with those features.
I don’t know as I don’t use that feature
To be honest, I don’t see a benefit for btrfs (or zfs). I prefer plain ext4 (no LVM). It’s simpler and faster. I have no need for snapshots. Proxmox handles my vms and my working machines are just a collection of dot files… But that’s just me. It’s good that there are choices.
Ext4 is slower than btrfs
It’s been a while since I looked at benchmarks (www.phoronix.com/news/Linux-5.14-File-Systems). It could be these days.
Its supposed to be called betterFS but Jim Salter keeps calling it butter FS. Doesn’t really inspire confidence. At least it’s gonna need… a better name
I don’t know who Jim is but I just call it butterfs
Jim Salter, the former mod of r/zfs ? Former Ars Technica ? Currently in the ’ 2.5 Admins’ podcast?
He’s the hot knife of butter FS.
Ok that still doesn’t ring a bell but he seems important to you so that’s good enough for me
