Hi
from /proc/stat i get the following
disk_io: (3,0):(167751,94458,3917566,73293,2420568)
(3,1):(59314,45093,2747844,14221,114376)
(11,0):(9855,9855,1258392,0,0)
except the device 11,0 is a cd-reader
and there is a device 11,1 which has been used
is there any reson why the stats dont show up ?
after all it is another disk.
thanks
James

Linux definetly broken in this area! Linux (2.4) does not report other
any devices over either major 16 or minor 16. e.g. no /dev/hdb or /dev/hdd.
For my 4 IDE disk (on two different controllers) I only get:
disk_io: (3,0):(355075,157636,1744492,197439,2633848)
...
I'm thinking about fixing this on my onw using this patch as base:

Both cdroms are accounted, but only into the same slot (11,0). In function
disk_index() at the end of include/linux/genhd.h, you can add a line
case SCSI_CDROM_MAJOR:
above the line containing SCSI_DISK0_MAJOR, and things will work as expected.
Several more complete patches have been floating around for a while.

Daniel.
