Anyone have experience using zfs on /

I currently have mdadm raid0 for several of my filesystems. i have raid0 for everything but /boot and /boot/efi. I have raid0 for / /home and so on. I am looking at changing to zfs striping. I back up with borg backup on a dedicated server so I am going for performance. However, I would like to have the data integrity that i would get zfs. I know how to do zfs on anything else not / or /home. However, has anyone actually do this on root and where it was bootable? I tried it in a vm and it was kinda cludgy. Calemaris doesnt klnow what to do with zfs. I saw the link on here that showed how to do it, and it works, but the resulting os is kinda messed up. I think i messed up somewhere along the line. I kinda got intrigued with this when i was installing pfsense. It uses zfs for a single drive. At first that confused me, but i later found out it was actually a good idea even for 1 drive.

Anyways, what is your opinion?

Just FYI

I have never seen any other users using a pre-built Manjaro kernel with zfs on root between 2024 and today.
It feels like zfs users have probably moved to other distros with better zfs support or a more active community.
Just let you know why no one here is answering your question.

wellā€¦ i booted from live and rsynced my root and home to another driveā€¦ followed the instructions on her for manjaro. and rsynced backā€¦ aftter some tweaking, it is up and running on zfsā€¦ and so far, i dont see any performance falloff vs raid0. If i ever did a clean install, that would be a trip though.

i loaded the linux611-zfs, zfs-utils, and zfs-dkms. Seems to be working just fine. fyi, there is a linuxX-zfs for 6.6 and 6.12 also.

The approach i took was /boot and /boot/efi was separate partitions. even refind works.

Most users use ext4. Also you may find a lot of experienced users here using btrfs. Your chances with zfs are small.

Try to :mag: search the forum with:

  • ext4
  • btrfs
  • zfs

and you will see yourself
:footprints:

okā€¦ i actually see a performance improvementā€¦ I have 64G mem so that may be part of it. I basically wanted to see if i could do it and get the data integrity benefits.

Thanks for the replies
