I have a 2 disk raid0 with 32k chunk size using raidtools 0.90 beta10
right now, and have applied stephen tweedie's raw i/o patch. the raw io
patch works fine with a single disk but if i try to use raw io on
/dev/md0 for some reason transfer sizes are only 512bytes according to
the scsi analyzer, no matter what i specify (i am using lmdd from
lmbench to test, lmdd if=/dev/zero of=/dev/raw1 bs=65536 count=2048,
/dev/raw1 is the raw device for /dev/md0). Mr. tweedie says it should
work correctly, so could this be a limitation with the linux raid
software? Thanks.
PS please cc replies to [EMAIL PROTECTED], thanks.
