--0000000000009f039505e5e94ea0 Content-Type: text/plain; charset="UTF-8" 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.
