January 30, 20215 yr I’m getting constant writes to my cache drive (500GB SSD) and after upgrading to 6.9 rc2 I hoped it would fix it. I have narrowed down the issues to btrfs and loop2 in iotop. My question is why is btrfs showing up when my drive is xfs? Is the docker image or something else formatted as btrfs and if so can it be changed to docker-xfs? Also I have really know idea what loop2 means but I guess its the cache drive configuring and how unraid utilizes it?
February 1, 20215 yr Author How do I go about changing my docker image from Btrfs to xfs in unRAID 6.9 rc2?

Post your diagnostics (Tools > Diagnostics) please. If I recall correctly LimeTech made some underlying changes to address the excessive writes in the betas but users also had to change the partition alignment: Edited February 2, 20215 yr by weirdcrap

February 4, 20215 yr According to your disk.cfg, your default FS type is XFS and all of your disks are either explicitly set to use XFS or are set to auto (which I assume means they are XFS as well). You can see that loop2 is the BTRFS disk image under the advanced docker settings: EDIT: Oh I apologize, I missed your second question. Quote How do I go about changing my docker image from Btrfs to xfs in unRAID 6.9 rc2? You don't, UnRAID doesn't allow you to use XFS for the docker.img file. BTRFS is your only option as far as I'm aware. Edited February 4, 20215 yr by weirdcrap

You can change it I the the settings. I plan on upgrading my cache drive anyways tomorrow so I will realign and format it.
