How to create RAM drive?
 

Hello everybody!

I would like to create a RAM drive using my Slackware 9. I tried compiling the RAM disk option and set the size as I wish (of course in Mx1024) in to the kernel.

I check the ramdisk.txt which comes with the kernel doc, that doesn't come helpful.

Basically, I want a RAM drive so I can mount it like any other drive. And use it like any other drive. Specifically, I want to do video editing/recording (maybe not a smart idea for recording :).

Oh yuh, one more question. I have 1GB of RAM on my comp. Why is /proc/meminfo reporting 9024XX(can't remember the exact number)?

Thanks in advance.

My /var/log/demsg says:
Those disks are accessible in /dev/ram0 through /dev/ram15 and they can be formatted and mounted just like a floppy disk or something.

In other words I just need to compile the kernel to support RAM disk and access it by mounting /dev/ramX.

So after booting up my Linux, just format it using
mke2fs [-j] /dev/ram0
and then
mount /dev/ram0 /mnt/ramdrive
and then I would able to use it as I wish.
Please correct me if I am wrong or missing out any steps.

Thanks.

Yes, you can configure the ramdisk parameters before you compile the kernel. Also, you can specify ramdisk parameters as kernel parameters at boot time. See /usr/src/linux/Documentation/kernel-parameters.txt
