HDD Partitioning and rc.rofilesys
From OESF
Configuring the MicroDrive
copied from "the Grinder"
What we have now: Windows FAT32 Partition (/dev/hdc3)
What we want: Ext2/3 Partition, either convert the whole /dev/hdc3 or part of it.(Mine is actually only a 1Gb partition[Ext2])
Notes:
This partition is /dev/hdc3 on my SL-C3100, but I was told it is /dev/hda3 on some Zaurii. So check with df -h and replace if necessary.
- su
- umount /dev/hdc3 (if it doesnt unmount the you need to kill the apps using it, see KillApps)
- fdisk /dev/hdc
* Use command t on partition 3, on set it to 83 * Exit with w to save changes
- mke2fs -j /dev/hdc3
KillApps
- fuser -m /dev/hdc3
and kill them with kill -9 $PID where $PID is one the numbers returned by fuser.
Tweaking the boot process
Procedure:
- mount -o remount, rw /
- cd /
- mkdir /hdd4
- cd /root/etc/rc.d
- cp -p rc.rofilesys rc.rofilesys.org
- use you favorite text editor to edit rc.ro.filesys
If you try to reboot now, the Zaurus will complain about a HDD3 problem. You can make it boot anyway by hitting Ctrl-C
Indeed, this partition is mounted by the startup scripts, and the type is forced to FAT. So weâEUR(TM)ll just edit those scripts. You must first remount the root filesystem to read-write: mount -o remount,rw /. Now you can edit /root/etc/rc.d/rc.rofilesys.
Note: look at my rc.rofilesys for what has been changed (with a #)
Note: I have heard of this minor problem when using the Zaurus as an external hdd(with Linux of course) there is a problem with usbd.agent thinking its a fat filesystem, when its a ext3 filesystem, I will look into this soon as I have time.
Here is my rc.rofilesys, I have divided the drive into 4 partitions, /dev/hdc1,2,3,4, being ext3,ext3,fat,ext2. The added lines will be in bold. Again this is for a SL-C3100.
