Hi,
We have a zfs file system configured using a Sunfire 280R with a 10T
Raidweb array
bash-3.00# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
filer 9.44T 6.97T 2.47T 73% ONLINE -
bash-3.00# zpool status
pool: backup
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
filer ONLINE 0 0 0
c1t2d1 ONLINE 0 0 0
c1t2d2 ONLINE 0 0 0
c1t2d3 ONLINE 0 0 0
c1t2d4 ONLINE 0 0 0
c1t2d5 ONLINE 0 0 0
the file system is shared via nfs. Off late we have seen that the file
system access slows down considerably. Running commands like find, du
on the zfs system did slow it down, but the intermittent slowdowns
cannot be explained.
Is there a way to trace the I/O on the zfs so that we can list out
heavy read/writes to the file system to be responsible for the
slowness.
Thanks,
--Walter
