Yes. Badari> And also, does the write test writes Badari> to multiple files in the same directory ? Or multiple threads Badari> writing to same file ? It's standard iozone --- mutliple processes writing to multiple files in the same directory. All the mount options are the defaults. A sample test is: mdadm -Ss mdadm -C /dev/md0 -l 0 -c 1024 -n 2 -R /dev/sdc /dev/sdk mke2fs -j /dev/md0 mount /dev/md0 /shift/oplapro97/data01 cd /shift/oplapro97/data01 iozone -MCew -t1 -f IOZONE -s32g -r256k -i0 -i1 > ~/tests/unsw_ext3/iozone_2_disk_1stream_ext3 rm -rf /shift/oplapro97/data01/* iozone -MCew -t2 -f IOZONE -s32g -r256k -i0 -i1 > ~/tests/unsw_ext3/iozone_2_disk_2stream_ext3 -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au The technical we do immediately, the political takes *forever* - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
