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.
