This is probably a dumb question - I'l imagine I'm just missing something
obvious, but here goes... Is there any way to newfs a vnode backed md()
filesystem on a sparc64 system, transfer the relevant file that served as
the md() vnode backed filesystem to an i386 system, and mount the
filesystem? I've tried all sorts of various flags to newfs and mount
without any luck. What am I missing?
An example below:
sparc64# uname -a

2003 matt@:/usr/src/sys/sparc64/compile/SPARKY sparc64
sparc64# dd if=/dev/zero of=myfiles bs=1024k count=5
sparc64# mdconfig -a -t vnode -f myfiles -u 1
sparc64# newfs /dev/md1
/dev/md1: 5.0MB (10240 sectors) block size 16384, fragment size 2048
