Hi.
bash-3.00# uname -a
SunOS XXXX 5.10 Generic_125101-04 i86pc i386 i86pc
Server is x4100.
NFS server under Sun Cluster with ZFS.
I issued ''zpool import'' to see other pool available to import
on one node and then I got very slow nfs access to that node, nfsd go upto ~3500
threads (from ~500) and load increased to few hundreds.
I couldn''t stop ''zpool import'' - after 2-3 minutes it
exited with no output (as ^C was send several times) and load immediately
dropped to normal level.
During ''zpool import'' it consumed entirely one CPU core and
nfsd consumed all the rest.
I did run for several seconds:
bash-3.00# dtrace -n fbt:zfs::entry''/pid ==
16919/{@[probefunc]=count();}''
dtrace: description ''fbt:zfs::entry'' matched 1085 probes
^C
arc_buf_destroy 10289
arc_change_state 10289
zio_buf_free 10289
arc_evict 730332
bash-3.00#
Server is running with zil_disable=1
?
