NFS and IO testing : Bonnie++

Been spending time lately testing out and trying to tune NFS mounts.

For testing IO, I've been using

• dd
• iozone
• bonnie++
• orion

This first option, dd, is fine for file creation tests and/or sequential reads but less flexible for random reads or random writes

To test random reads I thought I'd use iozone but don't see a solely random read test.

Then I thought I'd use the Oracle supplied tool, orion, to do random read test on an NFS mounted file system, but this doesn't work, at least on AIX 6.1, with my mount settings.

First orion test gave this error

$ orion -run simple -testname orion

ORION: ORacle IO Numbers -- Version 11.1.0.7.0

orion_20101123_1503

rwbase_read_luncfg: SlfFopen error on orion.lun

orion_parse_args: rwbase_read_luncfg failed

OK, have to create "orion.lun" with either my lun locations or my file locations. I put in file locations:

Now get another error

$ orion -run simple -testname orion

ORION: ORacle IO Numbers -- Version 11.1.0.7.0

orion_20101123_1508

Test will take approximately 9 minutes

Larger caches may take longer

orion_spawn: skgpspawn failed: Error category: 27155, Detail: 2

orion_main: orion_spawn failed

Non test error occurred

Orion exiting

Illegal instruction(coredump)

Looks like the "orion" executable wasn't being found, at least not by execve

so I ran it from my bin directory where the orion executable could be found. Now get another error

$ orion -run simple -testname orion

ORION: ORacle IO Numbers -- Version 11.1.0.7.0

orion_20101123_1510

Test will take approximately 9 minutes

Larger caches may take longer

storax_skgfr_openfiles: File identification failed on /kyle/system01.dbf

OER 27054: please look up error in Oracle documentation

Additional information: 6

rwbase_lio_init_luns: lun_openvols failed

rwbase_rwluns: rwbase_lio_init_luns failed

orion_thread_main: rw_luns failed

Non test error occurred

Orion exiting

If the datafile was on "/tmp" it word fine but if it was on my NFS mount it failed with the above error. Hmm - doesn't work over NFS?

Finally I decided to try bonnie++. I download, unziped, tar extracted bonnie++ , ran "./configure" and then make, but got error

$ make

make: 1254-002 Cannot find a rule to create target bon_io.o from dependencies.

Stop.

For some reason the rule for the ".o" doesn't seem to work:

Not feeling like trying to figure make out I just did it by hand

$ for i in *cpp; do

name=`echo $i | sed -e 's/.cpp//'`

echo "g++ -c $name.cpp $name.h bonnie.h port.h"

done > makeo

$ sh makeo

$ make

That worked. Test results coming
