dtrace script to monitor file access
A user has asked us to find out who is changing one of their files and how it is being changed. I came up
with the script below:
#!/usr/sbin/dtrace -s
#pragma D option quiet
BEGIN
{
printf("\n Timestamp gid uid pid ppid execname function current directory file name\n\n");
}

slow sync on zfs
Hello zfs-discuss,
Relatively low traffic to the pool but sync takes too long to complete
and other operations are also not that fast.
Disks are on 3510 array. zil_disable=1.
bash-3.00# ptime sync
real 1:21.569
user 0.001
sys 0.027
During sync zpool iostat and vmstat look like:
f3-1 504G 720G 370 859 995K 10.2M
misc 20.6M 52.0G 0 0

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?
