Re: [ts-7000] HOW TO transition to a journaling file system?

[Don Tucker <>]

Thank you, Clark!  That was a lot more straight-forward than I would
have expected.  Doesn't the kernel or initrd expect ext2 on partition 4?

By the way, "df -T" on the SBC returns (edited)

Filesystem            Type          Mounted on
rootfs                     rootfs         /
/dev/tssdcarda4   ext2           /initrd
...
none                                         /initrd/dev
none                                         /initrd/dev/shm
tmpfs                      tmpfs        /dev

I'm assuming that /dev/tssdcarda4 is partition 4 of the SD card, which
would indicate its using ext2.  I'll give your procedure a shot and see
what happens.

Thanks again!
