Ok, long story. But we have a 90ish TB vdev server in 5 drives and we deleted 40 ish TB of storage and then we waiting a week and rebooted it over the weekend as it had 620 days of up time…
Now its not booting (been trying too for the last 24 hours) and its looking like ots trying to do a scrub before coming online??
Support is only hardware (also maybe only m-f) but i need it back online by tomorrow night.
I’m not going to spend a lot of time with my head bent 90° to read your screen shots, but it does indeed look as though it’s slow to import your data pool. Why that would be is anybody’s guess at this point. Knowledge of the hardware might help (“R20” doesn’t tell us anything). Knowledge of which version of TrueNAS you were running would also help–apparently it was at least two years old given your uptime, but we don’t know how much older than that it may have been.
