Long Delay Between Done and Shutting Down Core

Post by NickOfTime »

I am seeing long delays between when a WU is completed and Done and the Shutdown and FINISHED_UNIT Returned

25m at 16:26 and 13m at 18:11....

Running Client 7.2.9 in Ubuntu 12.10 Desktop in Win8 Hyper-V
On 2P AMD 6234 with SMP 20 and thekraken installed.

Code: Select all

Welcome to the folding support forum NickOfTime.

You may be experiencing a barrier problem.

Can you please copy/paste /etc/fstab here.

If you don't see barrier=0 there is a fix compliments of Tear that you can copy/paste in a Terminal window after pausing and quitting folding.

Copy and paste the following as one complete line(triple click inside the code box or click on Select All above the code box so that everything in the code box is highlighted and then right-click and select copy ... right click in a Terminal window, select paste and press Enter ... you'll need to enter your Ubuntu password when prompted for it):

Code: Select all

sudo sed -ri '/barrier=/ {p;d}; /ext[34]/ {s/([ \t]ext[34][ \t]+)([^ \t]+)([ \t])/\1\2,barrier=0\3/}' /etc/fstab
If you decide to try this you have to reboot afterwards.

Code: Select all

UUID=51b13c14-b298-46cb-bf10-571a92bd15b7 /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=1f0081d3-9c12-4845-a23e-f469ac1ff1da none            swap    sw              0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0
Ok, Will add barrier=0 and reboot and see what happens...

Yep, Changing Barrier=0 Fixes the problem.
