Description:
15 minutes load average grows until 2 and stays Additional info: * linux-3.13 * System with bcache->luks->hdd Steps to reproduce: Start the system in any level (rescue or graphical) then observes the 15 minutes load average growing. The load stops near 2 at my case and never decays. I see this only in a linux-3.13 with bcache+luks. I searched about and not found any similar case. |
This task depends upon
I do not use LUKS.
I think someone is already addressing this problem or something like this. See: http://comments.gmane.org/gmane.linux.kernel.bcache.devel/2499
Maybe i can apply the patches today. If so, i will put the results here.
Kernel 3.14.1-1-ARCH, btrfs
For some reason bcache writeback is running even when cache mode is writethrough.
Execute "echo 0 > /sys/block/bcache0/bcache/writeback_running" has the same effect of patch applied before.
