Here is something that has been nagging me this week: I want to create and mount a ramdisk whenever the computer (AIX 5.1; I do not know if it really matters) boots up and before NFS is up. What I came up was a script that would

1) Create the device, allocating the amount of disk space I want, using mkramdisk.
2) Format the device, using mkfs, as jfs
3) Mount device
4) Unmount and remove the device when told to quit.

My problem is that I do not know how to make mkfs not to ask if I really want to format that device. There has to be a way around it; I am not the only one who need a ramdisk in AIX. But, how to do so?

Also can I tell smit to do all those steps for me so I do not need to run my script?

Hi
We have a productive cluster wich uses a 500MB ramdisk here the steps how we generate the ramdisk and how to get rid of it correctly.

This must be done each boot:
/usr/sbin/mkramdisk 512M
/usr/sbin/mkfs -V jfs /dev/ramdisk0
/usr/sbin/mount -V jfs -o nointegrity /dev/ramdisk0 /mountpoint
/usr/bin/chown -R user.group /mountpoint

Use as long as you wish and umount it with:
/usr/sbin/umount (-f) /mountpoint

If you want to delete it use:
/usr/sbin/rmramdisk /dev/ramdisk0

Cheers seth

Thanks for the reply! That got me running! Now I just need to finish making it as a startup script (probably tomorrow) and I should be golden.
