How do I change the size of a ramdisk?
If you want to make a ramdisk bigger, look at How big can a ramdisk be? first.
Create places to mount the old (current) and new (resized) ramdisks:
mkdir /mnt/old-ramdisk
mkdir /mnt/new-ramdisk
Create an empty ramdisk that is the size you want:
dd if=/dev/zero of=my-new-ramdisk bs=size-of-my-new-ramdisk count=1
mkfs.ext2 my-new-ramdisk
Unzip the old ramdisk and mount both ramdisks:
gunzip my-old-ramdisk.gz
mount -o loop old-ramdisk /mnt/old-ramdisk
mount -o loop new-ramdisk /mnt/new-ramdisk
Copy the contents of the old ramdisk to the new one:
cd /mnt/new-ramdisk
tar cf - -C /mnt/old-ramdisk . | tar xf -
Unmount the ramdisks and zip the new one:
umount /mnt/old-ramdisk
umount /mnt/new-ramdisk
gzip new-ramdisk
Note: If you just want a little more free space and you've been making lots of changes to your ramdisk, try making your new ramdisk the same size as your old ramdisk. You may find you have enough free space when the files are rearranged.
