Thanks for yr reply
i am using cache_dir aufs 10 GB each on each SCSI hard
drive .
i sometime get "await" stats of "iostat -x -d 6
"command like
peak value 2174.00 ms ( on machine with single drive )
peak value 1300 ms ( on machine with multiple drives
)
( await
The average time (in milliseconds) for I/O
requests issued to the device to be served. )
that mean using multiple drive aslo improve
performance .
Regards
