maemo.org - Talk - eMMC got corrupted

Let' try! I split the code because of the second command which spans for 5 lines! Each box is just one command.
First: Create and write the partition table to the device:

Code:

sudo gainroot

Code:

echo "unit: sectors

 > /dev/mmcblk1p1 : start=       64, size= 9355200, Id=0

 > /dev/mmcblk1p2 : start=  9355264, size= 4194304, Id=0

 > /dev/mmcblk1p3 : start= 13549568, size= 1572864, Id=0

 > /dev/mmcblk1p4 : start=        0, size=       0, Id= 0" > table

Code:

sfdisk --no-reread /dev/mmcblk1 < table

Then reboot.

Second: Activate the partitions and apply the file systems (each line one command):

Code:

sudo gainroot

sfdisk -c /dev/mmcblk1 1 c

mkfs.vfat -F32 -n MyDocs /dev/mmcblk1p1

sfdisk -c /dev/mmcblk1 2 83

mkfs.ext3 -L optfs /dev/mmcblk1p2

sfdisk -c /dev/mmcblk1 3 82

mkswap -L swap /dev/mmcblk1p3

Now copy the content of /home and /opt to the new partition

Code:

mount -t ext3 /dev/mmcblk1p2 /mnt

cp -a /home/* /mnt

mkdir /mnt/opt/

cp -a /opt/* /mnt/opt/

Third: Change some system files to reflect the new setup:

Code:

apt-get install nano

nano /usr/lib/genfstab.awk

Comment out the last 10 lines

Quote:

start == 1 && $6 == 83 && !__home {
printf "%s /home ext3 %s 0 0\n", $1, home_opts
printf "/home/opt /opt none bind\n"
__home++
}

start == 1 && $6 == "c" && !__fat {
printf "%s /home/user/MyDocs vfat %s 0 0\n", $1, fat_opts
__fat++
}

This will make sure there will not be an autogenerated fstab anymore.
Now edit /etc/event.d/rcS-late

Code:

nano /etc/event.d/rcS-late

Find the line

Quote:

-f /usr/lib/genfstab.awk > $tmp_fstab

and add this below it

Code:

echo "/dev/mmcblk1p2 /home ext3 rw,noatime,errors=continue,commit=1,data=writeback 0 0" >> $tmp_fstab

echo "/home/opt /opt none bind" >> $tmp_fstab

echo "/media/mmc1 /home/user/MyDocs none bind" >> $tmp_fstab

echo "/dev/mmcblk1p1 /home/user/MyDocs vfat noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir 0 0" >> $tmp_fstab

This is the basic setup. The last line of code might work, but might as well be overwritten by some other maemo settings, it is experimental, so don't use the MyDocs folder without further testing, including a couple of reboots to be sure.

Hope it helps!
