Hi Alexey, and again, thank you for the script. I have used this successfully many times, and this way have found ZFS to be sufficiently reliable under the regular 32bit RPiOS to be used in production machines across several kernel updates.

However the script errors out under the recently-released kernel 5.10.11 updates, returning the following. Any guidance as to how I might fix this would be appreciated!

FYI the 2.0.x zfs-dkms and related packages in the upcoming ubuntu 21.04 support linux 5.10.x

Thank you. So realistically nothing can be done (other than downgrading the kernel) until the updated zfs-dkms also appear in the RPiOS repos? Or could I try building zfs-dkms from source and then retrying the script above?

@satmandu what's the best way currently to install the 2.0.x zfs-dkms (and related) on 5.10.x (raspberrypi os)?

@jimmont Easiest way would be to upgrade to bullseye, as zfs 2.0.x is already there: https://packages.debian.org/bullseye/zfs-dkms

(The only pain in upgrading to bullseye was that IIRC I had to upgrade to gcc-9 and remove some gcc8 library package which I no longer needed which was holding up other package upgrades.)

(This is assuming that you are on the 64 bit Raspi-OS of course.)
