It's a bit strange that it is trying to start so many threads at startup
time. How much RAM and how many CPUs on this node?
Indeed strange, since there is a hard-coded max of 512.
And that error message seems to indicate that min > max.
Hmm - oops.
As andreas suspected, min can be arbitrarily large depending on number
of cpus and memory.
Need to fix that immediately.
In the meantime, you can set this in modprobe.conf:
options ost ost_num_threads=512
