This time, I got a different error, but only after my tests were running for
quite some time. Thus, the log files are very large. Hopefully, you will be
able to find something from them.
iozone gave the following error:
read: Bad file descriptor
Here's the script I ran which ran iozone with varying file sizes and record
sizes.
#!/bin/bash
num=`hostname | sed 's/.baz.emsl.pnl.gov//g' | sed 's/x//g'`
cd /mnt/cephfs
# start at 16 gigs
export FSIZE=16777216
while [ $FSIZE -le 33554432 ]; do
export RECORD=64
while [ $RECORD -le 16384 ]; do
/home/berwin/iozone3_303_centos5/src/current/iozone -s $FSIZE -r
$RECORD -i 0 -i 1 > /home/berwin/fstests/ceph/iozone/output$num-$FSIZE-$RECORD
RECORD=$(( $RECORD * 2 ))
done
FSIZE=$(( $FSIZE * 2 ))
done
