dmu_zfetch_find - lock contention?
...sqlcluster-2-1[~]
Now I didn''t have much time to look around and had to redirect live traffic somewhere else but before I did I managed to get the below:
# dtrace -n profile-997''{@[stack()]=count();}''

zpool import hangs indefinitely (retry post in parts; too long?)
Now at 36 hours since zdb process start and:
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
827 root 4936M 4931M sleep 59 0 0:50:47 0.2% zdb/209
Idling at 0.2% processor for nearly the past 24 hours... feels very stuck. Thoughts on how to determine where and why?

gzip compression throttles system?
I just had a quick play with gzip compression on a filesystem and the
result was the machine grinding to a halt while copying some large
(.wav) files to it from another filesystem in the same pool.
The system became very unresponsive, taking several seconds to echo
keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty
of grunt for this.
Comments?
