Along with the Unraid version, the kernel version is one of the important variables that I want to find out when I open the dashboard. Could you please show it in UNRAID or SYSTEM section by default or put it into the tooltip of Unraid version info icon at the very top. Thanks in advance, Björn

I'm also interested in this configuration. All my large HDDs should form a large BTRFS RAID 1 storage. I know Unraid was designed to be the opposite of RAID but over time filesystems, technologies and user needs change. Is there a chance that it will become a feature of Unraid?

zstd is my preferred one. I can't prove which algorithm would fit best as it is highly dependent of the usage scenario. As zstd isn't available out of the box, one can't make measurements easily. I'm fine with lz4 for the moment as everything else work as expected and Yann Collet is the author of the both algs Thanks for your effort.

lz4 works fine. # zramctl --find --size 8GiB -a lz4 /dev/zram0 But zstd emerges everywhere. Even zramctl --help mentions it <alg> specify algorithm, supported are: lzo, lz4, lz4hc, deflate, 842 and zstd

It would be great if zstd compression is also supported: # zramctl --find --size 8GiB -a zstd zramctl: /dev/zram0: failed to set algorithm: Invalid argument

I'm interested in ZRAM support in Unraid too. I can't create a traditional swapfile because the cache pool (/mnt/cache) is backed by a btrfs RAID1 filesystem and that isn't supported. root@unraid# modprobe zram modprobe: FATAL: Module zram not found in directory /lib/modules/5.15.43-Unraid but zramctl is installed... root@unraid# zramctl -V zramctl from util-linux 2.37.4
