What Process is using all of my disk IO

If I use "top" I can see what CPU is busy and what process is using all of my CPU. If I use "iostat -x" I can see what drive is busy. But how do I see what process is using all of the drive's throughput? ...

Map sd?/sdd? names to Solaris disk names?

Some commands in Solaris (such as iostat) report disk related information using disk names such as sd0 or sdd2. Is there a consistent way to map these names back to the standard /dev/dsk/c?t?d?s? disk names in Solaris? Edit: As Amit points out, iostat -n produces device names such as eg c0t0d0s0 instead of sd0. But how do I found out th...

How to interpret iostat?

I track a lot of parameters on my Server and the only thing I can't realy put in perspective is the IOstat.

Then, from kernel version 2.6.x some metrics were measured only at the disk-level, and hence the parsing algorithm was based on the number of metrics associated wi...

grep -v and -B|-A|-C not working together

I need to scan the output of iostat -En on a Solaris machine such that when a disk with errors is found, two lines about that disk are sent to the final output. This works fine so far using iostat -En | grep 'Errors: [1-9]' -A 1 but when I try to not include CD/DVD devices, I hit a wall. The contaxt flags (-A|B|C) don't seem to work w...

FreeBSD iostat - How to tell if there's a problem?

Hi, I run a FreeBSD NFS server and recently I've been having odd issues throughout the cluster (the Apache servers are hanging in "lockf" state when loading files from the NFS share, etc). I'm fairly new to this, so my question is how can I tell if a server's IO is getting overloaded? Here is my current iostat: [root@host ~]# iostat...
