/dev/shm's how I would do it.
Make a file on /dev/shm and the format it, mount it, export it.
dd if=/dev/zero of=/dev/shm/export bs=1M count=1000 mke2fs -j /dev/shm/export mount -o loop /dev/shm/export /mnt/foo
Then export /mnt/foo
Thanks for this.
One note though, it does not seem to work if I mount the ramdisk into a subfolder and export the parent folder. e.g mount to /mnt/test/ramdisk and export /mnt/test would given the same problem. But mounting directly to /mnt/ramdisk and export /mnt/ramdisk is OK
When you export a file system, *other* file system mounted under the exported file system are not exported. This is normal (and I believe documented) behaviour of NFS.
