[opensuse] Strange disk activity
Hi,

I noticed in the graph of disk activity in GKrellM that there was some
constant but intermittent activity on /dev/sda. Like this:


__|__|__|__|__|__|__|__|__|__|__|__|__|__|


It suddenly occurred to me that with GKrellM one can display a graph per
partition! So I activated graphs for each one in /dev/sda and found the
culprit: /dev/sda7.

What do I have there? Well, nothing:

Telcontar:~ # mount | grep sda7
/dev/sda7 on /other/test_a1 type reiserfs (rw,relatime,lazytime,
user_xattr,acl)
Telcontar:~ #


It is a test partition of another system, nothing is active there:

Telcontar:~ # cat /other/test_a1/etc/os-release
NAME=openSUSE
VERSION = 12.1 (Asparagus)
VERSION_ID="12.1"
PRETTY_NAME="openSUSE 12.1 (Asparagus) (x86_64)"
ID=opensuse
Telcontar:~ #



I umounted it and the activity disappeared. Mounted it again and it kept
silent. What was it? How can I find out the next time what is reading there?

I see a similar intermitent activity on other partitions of disk
/dev/sdc, on these partitions:

/dev/sdc6
/dev/sdc7
/dev/sdc12
/dev/sdc14
/dev/sdc17

Telcontar:~ # mount | grep "sdc6\|sdc7\|sdc12\|sdc14\|sdc17"
/dev/sdc17 on /home type ext4 (rw,relatime,data=ordered)
/dev/sdc14 on /data/homedvl type reiserfs (rw,relatime,lazytime,
user_xattr,acl)
/dev/sdc7 on /usr/local type reiserfs (rw,relatime,lazytime,
user_xattr,acl)
/dev/sdc12 on /usr/gamedata type reiserfs (rw,relatime,lazytime,
user_xattr,acl)
/dev/sdc6 on /usr/src type reiserfs (rw,relatime,lazytime,
user_xattr,acl)
Telcontar:~ #


So yes, it affects most of my reiserfs partitions (/var/spool/news is
not affected). What is going on?
