After few days running, my DEC750 freeze.
Console port says something about
zfs: WARNING: Pool 'zroot' has encoutered an uncorrectable I/O failure and has been suspended
AI help me to check temperature was too high, so I changed place and now it seems to be ok (according to os-smart: max 68°C)
Anybody have an idea how to troubleshoot (console is not usable) ?
Your SSD might be failing. Run a long SMART test. Also run a zpool scrub.
I did many tests and there is no failure. AI suspected too much write on it, then I reduced rules log, rddtools and some settings.
Let see for next tests
