/proc/partitions disk usage

Fippy · 03-09-2005, 09:14 PM

I am trying to use /proc to programatically obtain equivalent data to that found via "df".

I can't seem to find out Blocks Used and Available from anywhere in /proc.
None of my research seems to explain what all those esoteric fields in /proc/partitions are, and if they are related to disk usage.

Does anyone know where "df" gets Used and Available from please?

Thanks,
Fippy.

Hi,

Guess you are using a 2.6 kernel?

Take a look here for an explanation of all the fileds:

df gets its info by calling, among others, the statfs function (man statfs for more info). Run strace df to see for yourself.

Hope this helps.

Thanks, I always wondered what all those fields are. I'm using Kernel 2.4 actually.

Alas, that data still doesn't get me disk partition usage stats.

I don't think /proc has that info.
The best I have come up with is to use /proc/partitions and /etc/mtab to get a list of partitions and then cycle through each doing a statfs.

Thanks for your help.
Fippy.
