No ext3 here, just XFS. I believe it's been added recently. On at least one system, I had to get a newer version of tune2fs. On the older man page, -j wasn't listed (I presume it wasn't supported, either).

Hrmmm...what's the '-j' switch? I can't find any reference to it in the man page. Have no idea if this has any bearing, seeing it works on one and not the other. The -j switch is used by tune2fs to install a journel to the ext2 fs and enable it as ext3.

Nope. mke2fs -j /dev/xxx works aok. I do use tune2fs -c 0 -i 0 /dev/xxx as soon as it has been made so that I won't ever hear from fsck.

mystery with mke2fs -j
Prior to making major updates to my system, I always clone my running system to a spare partition and verify that it boots and runs.
