Hi,
Running stable/10@r273159 on FC disks (through isp) I can't create a zfs
pool.
What I have is a simple device, accessible on /dev/multipath/sas0,
backed by da0 and da4:
# gmultipath status
Name Status Components
multipath/sas0 OPTIMAL da0 (ACTIVE)
da4 (READ)
When I issue a
zpool create data /dev/multipath/sas0
command, zpool starts to eat 100% CPU:
# procstat -k 3924
PID TID COMM TDNAME KSTACK
3924 100128 zpool - <running>
gstat shows that there is one uncompleted read IO on multipath/sas0 and
the queue length constantly grows on da0:
# gstat -b
dT: 1.030s w: 1.000s
L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name

I can use these devices finely with dd.
What's going on here?
