NFS and IO testing : Bonnie++

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

For testing IO, I’ve been using

1. dd

2. iozone

3. bonnie++

4. 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:

$ cat orion.lun

/tmp/system01.dbf

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

$ truss -f orion -run simple -testname orion … 700502: execve(“orion”, 0x0FFFFFFFFFFBF2D0, 0x0FFFFFFFFFFFFB30) Err#2 ENOENT

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:

%.o: %.cpp %.h bonnie.h port.h

$(CXX) -c $&lt

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
