I'm trying to create an EXT2 partition so I can share files between
FreeBSD and any other operating system I put on the computer, without
the limitations of FAT32.
My kernel config is the generic kernel, with a bunch of SCSI, RAID and
network drivers, MD_ROOT and NFS_ROOT commented out.
However, once I'm done making the partition, I can't mount it. When I
try mounting it, I get the following error.
mount: /dev/ad8s1 : Operation not supported by device
Can anyone tell me what I'm doing wrong?
I sync'ed the ports tree within the last week, and built the e2fsprogs
port this morning.
Thanks,
-Jim Stapleton
The process I went through to create/mount the partition is as follows:
