Zimbra performans problem

Post by zgokan »

Hello

There are 200 mailboxes. Hard drive performance is not enough. I am constantly getting an i / o error. The system is on KVM.
The disc type is Qcow2. The total size is 1.5T.

Error: task jbd2/dm0-8:456 blocked more than 120secs

I would do the following for the solution. Do not you have a problem?
"echo 0 > /proc/sys/kernel/hung_task_timout_secs"

Defaults:
# cat /proc/sys/kernel/hung_task_timeout_secs
120


Thanks.

Not:
Release 8.7.0_GA_1659.RHEL7_64_20160628202714 RHEL7_64 FOSS edition.

Hello,

Seems your problem is more related to your hardware than your software.
