Determining the size of the buffer cache for individual devices.

[Abhishek Gupta]

Hi all,

Does someone know of a way to estimate the instantaneous size of the 
buffer cache for individual devices? For example, if there are two devices 
on your system a)/dev/hda1 and b)/dev/hda2 and each is running a different 
workload. How can we calculate the amount of cache being used by each 
devices individually?

Please advise. Thanks.

Abhishek
