Hi,
I am getting above error for creating directories ~1000. I have tried below steps (as tweaks or work arounds) but it doesn't seem to work.
1. Add the o_direct flag to the config files.
2. Reduce the number of threads from 32 to 8, (will be increasing this count till it breaks).
3. After each group of tests echo 3 >/proc/sys/vm/drop_caches to flush the filesystem cache.
Found this one better,
# free && sync && echo 3 > /proc/sys/vm/drop_caches && free
Parameter File
fsd=fsd1,anchor=/tmp/dir,depth=1,width=1,files=1000,size=40k
fwd=fwd1,fsd=fsd1,operation=read,xfersize=4k,fileio=sequential,fileselect=random,threads=1
rd=rd1,fwd=fwd1,fwdrate=max,format=yes,elapsed=10,interval=1
The vdbench is executed as SSH from another PC.
Forum Thread:
vdbench fail with hearbeat error on centos 6.5 running deadline i/o schedular at 360 second run stop
Does this issue still persists in the latest versions ?
Is there any solution to the issue.
Thanks in advance.
