Public bug reported:
Description: Ubuntu 8.04.1
Release: 8.04
open-iscsi:
Installed: 2.0.865-1ubuntu3
Candidate: 2.0.865-1ubuntu3
Version table:
*** 2.0.865-1ubuntu3 0
500 http://us.archive.ubuntu.com hardy/main Packages
100 /var/lib/dpkg/status
When the server boots up from a complete power down the IO speed of the iscsi
disks performs 100 times slower than it should. To resolve this problem, after
weeks of trying different things, I force downgrade to a older open-iscsi
package and then upgrade right back using this command:
dpkg -i /root/open-iscsi_2.0.730-1_amd64.deb ; /etc/init.d/open-iscsi restart ;
aptitude install open-iscsi
Every time I perform this step the IO performance immediately jumps back up to
where it is suppose to be.
I am having this problem on two Ubuntu 8.04.1 servers one running Dell
Hardware the other Supermicro. Nothing else in the data center is
having any IO performance problems with the Iscsi device.
