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? -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
