PSA: In case you run #Ubuntu 24.10 with #ZFS on Root, DO NOT TRY TO UPGRADE YET! You are very likely to run into a #Linux kernel deadlock mid-flight during the upgrade which leaves you with a broken system. …

System deadlock during Ubuntu upgrade 24.10→25.04 with ZFS root due to update-grub calling `ls /.zfs/snapshot/…` via `10_linux_zfs` causing kernel lock at mount.zfs · Issue #17337 · openzfs/zfs

New ZFS AnyRAID feature would probably get me to use ZFS at home instead of btrfs.
I have a lot of different-sized old SATA enterprise SSDs retired from @… and a cheap 8 bay eSATA enclosure. The performance is good enough. I can't really justify buying 8 new, matching drives.
AnyMirror would be good enough for my purposes.

Introducing ZFS AnyRaid, Sponsored by Eshtek — HexOS
At the beginning of this year, we made the decision to invest a substantial chunk of capital to support an open source project for which we have great personal interest.  ZFS AnyRaid will give users the ability to mix different sized drives in a pool, a highly-requested feature since our la

Overtone Rabi oscillation of optically polarized triplet electron spins and nuclear hyperpolarization in powder
We report coherent overtone Rabi oscillations of optically-polarized triplet electron spins and nuclear hyperpolarization in powder samples at room temperature. The strong orientation dependence through the zero-field splitting (ZFS) interaction in the single-quantum transition is overcome by coherently driving the significantly narrower overtone transition. Analytical formulas for the overtone lineshape and nutation functions for axially symmetric ZFS interactions are derived. Overtone Rabi os…

For the past month, I have been flitting about from one project to another as my ADHD sees fit. Today, that MO has to end if I'm ever going to complete this #homelab setup.
So, in order, I have to:
* Back up all my LXC's
* Install RAM in a Mac mini
* Reinstall ProxMox with #ZFS

I don’t think I know how to add a new disk to an existing pool on TrueNAS…
