Disk activity analysis

[Vinagre]

I'm testing Fedora rawhide, and with the introduction of the new fs, ext4 and btrfs, my ear is tuned to the disk sound, but it would be easy to see what's happening, so is there a tool to Disk activity analysis?

Perhaps this should be a feature to System Monitor

[notageek]

# yum install sysstat
# iostat
# iostat 2

The output is a little terse, the second example calls the command every 2 secs.

[marko]

yum install iotop

then run iotop,

there are some useful arguments, just run

iotop --help

to see them
