multiload's harddisk monitor stuck at 0
Last modified: 2020-11-06 19:57:31 UTC
Please describe the problem: i added the harddisk monitor thingy and it stays black and shows "0% in use" althouth my first hd is under heavy load. (i have two disks connected atm, /dev/sda and /dev/sdb, the second spun down most of the time) i guess it does not work with device mapper: i have lvm over dm-crypt. and there is a launchpad bugreport about software raids. from that bug report i gathered, that the applet monitors /proc/diskstats but since neither manpage nor gnome docu say exactly what it should do, i can't comment further. can you elaborate what it should exactly monitor please? btw the multiload_applet manpage does not mention the harddisk monitor at all. im using ubuntu 8.10 amd64 and gnome-applets 2.24.1-0ubuntu1 Steps to reproduce: Actual results: Expected results: Does this happen every time? Other information: example stats: one dm is the lvm, that other one the dm-crypt device, both use sda2 8 0 sda 4136025 1445039 748210273 15903908 2896809 82485923 683225290 244271988 0 14991932 260734612 8 1 sda1 236 436 10884 1212 2 0 10 0 0 1104 1212 8 2 sda2 4135760 1444560 748198813 15902260 2896807 82485923 683225280 244271988 0 14990992 260732936 8 16 sdb 620374 29750864 74703540 2500088 293927 31615097 134473502 217004992 0 2419600 219832084 8 17 sdb1 50908 1323519 9519298 114016 0 0 0 0 0 93168 113988 8 18 sdb2 5 0 28 56 0 0 0 0 0 56 56 8 21 sdb5 174576 5620521 41648586 359772 0 0 0 0 0 279420 359720 254 0 dm-0 5579676 0 748197952 38412972 85403160 0 683225280 4076553284 0 17354140 4114979840 254 1 dm-1 5579124 0 748197346 38416576 85403160 0 683225280 4076633744 0 17355924 4115199504
Same here on Ubuntu 8.10 x86 (32 bits) and gnome-applets 2.24.1-0ubuntu1, here is the output of my mount command: /dev/mapper/Ubuntu-root on / type ext3 (rw,relatime,user_xattr,errors=remount-ro) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) /proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) varrun on /var/run type tmpfs (rw,nosuid,mode=0755) varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) fusectl on /sys/fs/fuse/connections type fusectl (rw) /dev/sda1 on /boot type ext3 (rw,relatime) securityfs on /sys/kernel/security type securityfs (rw) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/ogrisel/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=ogrisel) AFAIR it use to work with previous versions of Ubuntu 7.10 almost surely and probably 8.04 too. I haven't changed my hard drive settings since that time, I just followed the regular Ubuntu upgrading steps.
system-monitor applet does not work at all for any lvm filesystems. It only reports activity for me in the extremely rare case when the /boot slice is being read/written. This is a very long-standing bug that needs much higher priority due to its very high visibility.
