Those highly-anticipated (by me) SATADOM devices should arrive on Friday. I won't get to play with them until next week.
I've been thinking about them all week, knowing that I can't proceed with the storage work until they arrive.

Should I move from BIOS booting to UEFI on my Dell R730?
I've never used UEFI on my hosts, and I'll be moving my zroot zpool to new devices soon.

I have monitoring checks to ensure all zpools are fine (e.g. zpool status).
I don't have one which verifies a given list of zpools all exist.

That means I'll be installing the new hardware today - instead of my usual wait-for-delivery process.

Now that I've decided to do `zfs replace` instead of `zfs send | zfs recv`, I've hit a conundrum.
If I want to move from lz4 to zstd, the `send | recv` is the way to go. Best I can do is change the zpool compression manually. That will only affect new writes.

Found this 4GB IDE drive in a desktop being recycled from a relative’s home. PSU fires up but screen remains blank. I may have to resort to destruction to dispose of this. Usually I just dd over the drive. That’s enough for this use case.
