IIRC the original ramdisk block device was kind of screwy, and I don't think it'll support that much space. One hack I could think of to get a 4G, in-memory, block device (untested but should work I believe): - mount a tmpfs a little larger (don't know how much overhead there is so 4100m is a guess): mkdir /srv/foo mount -t tmpfs -o size=4100m tmpfs /srv/foo - create a 4G backing file: dd if=/dev/zero bs=1M count=4K of=/srv/foo/backing.img - attach it to a loopback device: losetup -f --show /srv/foo/backing.img -- Chris Adams <linux@xxxxxxxxxxx> -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
