PogoPlug v2 pink Convert rootfs to ext3?

[moonman]

Is there a way I can convert rootfs to ext3? I am so sick of disk errors and random glitches in apps because of that.
I read somewhere that I can make a /boot partition (ext2) with copy contents of /boot folder to it. Is there anything else I would have to do to make it work? I suppose I would have to rebuild the kernel image so that it knows /boot is separate partition now?

Any suggestions are appreciated.

You can convert an ext2 filesystem to ext3 easily.. all you're doing is adding a journal. For the v2 and Dockstar, you don't have to go all complex on it. There's a U-Boot variable called 'rootfs' or 'rootfs_type' that you can just change from the default 'ext2' over to 'ext3' and you're basically done. That's all I did for a Dockstar.

Well, that was easy. Thanks kmihelich.

You guys should add it to the installation guide so that users won't have to struggle with ext2.
So users would have to issue /usr/sbin/fw_setenv usb_rootfstype ext3 after running Jeff's U-Boot script and format the hdd/flash drive as ext3.

How do you convert once you've already done the install.
I've done the tunefs -j

Can I do the /usr/sbin/fw_setenv usb_rootfstype ext3 ?

Will that automatically update mtab?

I used my computer to do tune2fs. While the hdd was disconnected I booted up the pogo os and /usr/sbin/fw_setenv usb_rootfstype ext3. mtab won't be updated automatically. It will probably error out because it won't find the journal.

Your method worked, and mtab was updated. Next question, I want to change the journal options to have better recovery of data. The default is writeback, for this plug I would like to set it to ordered. I can't edit mtab, so what can I do?
Thanks

Found the answer in the archwiki for ext3
tune2fs -O has_journal -o journal_data /dev/hdXY

running efsck on the drive also seems to help it be integrated into the ext3 configuration.
