would you, please, share your stress test? File System stress test is a collection of "bonnie, dbench, fs_inode, fsstress , fsx_linux,IOZone, postmark, tiobench" run parallely. You should be able to get the source code from the web. *** Bug 5536 has been marked as a duplicate of this bug. *** would you, please, provide the information about the tests parameters? These are the parameters
Tests Parameters
bonnie -u root -d $TESTPLACE -s 8192:256 -n 10
dbench 30
fs_inode $TESTPLACE 100 200 100
fsstress -d $TESTPLACE -n 100 -p 5000 -X
fsx_linux -N 100000 $TESTPLACE/fsx-linux.$FS_TYPE
IOZone -a
postmark set size 10 100
set number 100
set transactions 95
set location $TESTPLACE
show
run
quit
tiobench --block 4096 --block 8192 --threads $THREAD --size 3066 --numruns 10
Note:
$THREAD will take values 2,4,8 in the order
$TESTPLACE will point to location where the executables are located
I see XFS in the traces, so the patch to init bh->b_private on allocating buffer heads should fix this one. http://www.kernel.org/hg/linux-2.6/?cs=589b23656d52 |
