Occasionally Interesting, often not

Might as well put this up because I had a bit of a time finding info on this. The question is, how do you make a large ramdisk on linux (specifically for me, Red Hat Enterprise 4). Took a combination of other people's posts to put it together. The basics are: 1. Edit /etc/grub.conf to add ramdisk_size = xxx (in kb) at the end of the 'kernal' line. I wanted to get a 1G ramdisk, so: ramdisk_size = 1000000 2. Reboot. 3. Double check things are ok: dmesg | grep RAMDISK 4. Then format the disk. I want the whole 1G in one disk. And here's the little tidbit. Apparantly, the default behavior for mke2fs is to create block sizes of 1024 for ramdisk sizes "wrong fs type, bad option, bad superblock on /dev/sda1, or too many mounted file systems" when you try to mount your ramdisk. So you need to do this: mke2fs -b 1024 -m 0 /dev/ram0 (-m is optional; use if you don't want space reserved for root user) 5. Now you can mount the ramdisk: mount /dev/ram0 /var/mountpoint 6...
