Hi, perhaps I'll be more successful here - if you read questions@ too, please excuse :-) additional question: is it possible that what I describe below is a result of an import attempt on linux (Fedora 34)? thx Michael ---------- Forwarded message --------- From: Michael Schuster <michaelsprivate@gmail.com> Date: Wed, Aug 10, 2022 at 10:57 PM Subject: Catastrophic I/O error in root pool To: questions <questions@freebsd.org> Hi, After several months of not booting my laptop with FreeBSD current (been using linux off a different part of the same SSD), I attempted to do so yesterday, only to be confronted with a boot failure and a message about catastrophic I/O failure in the root pool (exact words may be different, typing from memory). Attempts to import the pool while booted from FreeBSD USB stick caused the system to hang, also with the same message on the console. Importing a different pool from the other SSD worked. I then booted linux and ran "dd if=/dev/nvme... of=/dev/null" over the complete partition w/o a single glitch. (I did NOT attempt to import the pool here, that's caused a different sort of problem previously) Finally, I installed and ran smartctl (still on linux), which - although it doesn't know about my specific device - seemed to indicate "no error". Any data important to me is on the working pool, so I'm prepared to overwrite the root pool, unless there's good reason not to (like a simpler fix for the current situation :-) ) TIA for all and any hints, pointers, advice.
