Hi Patrick, Did you remember to install the e2fstools (i.e., e2fsck) from ports? BTW: I had an ext2 partion on my laptop (5.0-R) that I wanted to share with a linux installation, which I run ocassionally on the same machine. Essentially doing what you are talking about here (running ext2 from freebsd in r/w mode) trashed the ext2 partion so bad that I had to newfs it in the end. (Luckily it was just a means to move data which was backed up elsewhere.) While that partition was still "living", I had to boot to linux to fsck it manually (e.g., after a system crash or the like). Otherwise, I had it marked 'noauto' in fstab, and mounted it manually as needed. Now, believe it or not, I'm using a FAT32 partition to do the same data exchange, (reasoning that both OS's support for FAT32 is better than their respective support for ext2 or ufs). I've had no problems after making that change. /Paul Patrick Quealy wrote: > I compled ext2 support into a kernel and I am able to mount and read an > ext2 partition fine.
