I am trying to mount my ext2 partitions under freebsd,
but with little success.
Yes, I have recompiled my freebsd kernel with EXT2FS.
Looking at the tables below I suspected the linux partitions might
have names ad0s3[bcd] so empirically I tried but got
su-2.05# mount_ext2fs /dev/ad0s3c debian/
mount_ext2fs: /dev/ad0s3c: Invalid argument
They reside on logical partitions, so I tried
su-2.05# sh MAKEDEV ad0s6
su-2.05# mount_ext2fs /dev/ad0s5 /mnt/debian/
mount_ext2fs: /dev/ad0s5: Device not configured
I am running 4.3-RELEASE.
help! :)
Please CC me, I am not on the list
