Hi all, I just find the mount point /data is in ext4, but /cache and /dbdata both still in rfs. Can I umount /cache and /dbdata manually, then run
mke2fs -t ext4 /dev/XXXX
then change fstab, and reboot the phone?
So, what's the point in avoid using any lagfix? As far as I know lagfix will do exactly what you stated in your post, use mke2fs to convert any partition to ext4.
If /cache and /dbdata were not in ext4 maybe the lagfix you used wasn't supossed to convert those.
I already applied lagfix, and it work good, I don't want to apply another lagfix just to fix those 2 mount point.... as I never smooth to get lagfix working..... doing it step by step myself sound better

Emm, have you tried speedmode or SO kernels? Essentially it is what you are asking
OK, so what kernel have you flashed?
First, dbdata contains important system data, mke2fs would clear it,
and you would end up with unusable system. And you have no guarantee
that init script of kernel you are using actually cares what's in fstab. It's
best to do this consistently - I sugest to go back to stock FS (rfs),
and then flash Voodoo Kernel. Except for Voodoo Sound and few tweaks,
it's like stock, without useless bloatware. Seems to be fastest according
to Quadrant, too.

Thanks, would you point me to some links about that? Sorry I haven't done good research before.

Just do some search, that is another lagfix, can I safely apply multiple lagfix to single device? I will search for the lagfix I used when I at home
HI, the lagfix I applied is ZSJP3 , the kernel is I9000ZSJP3-zImage
To be safe, you should remove all previous lagfix first. Afterwards, flash SpeedMod Kernel via Odin. You can find detailed instructions in the speedmod thread. To put it simply, download the Odin file, get Odin off www.samfirmware.com, put the file you downloaded into "phone". Leave everything else untouched and flash. Afterwards, go into recovery to activate the Lagfix options.

Thanks, but how to remove previous lagfix?
Hi,
need steps to change rfs to ext4? And does it require data wipe?
I am on SGS I9000 + 2.3.5 stock jvt
Regards.
No data wipe required, flash a kernel with ext4 included, boot into recovery and apply lagfix. Be sure to remove lagfix before flashing another rom in cwm.
Some kernels will require chainfires ext4 tools application.
Go to develop section and have a read up.
no data wipe but for security just make a backup coz sometime it hangs but not everytime.....just convert ur partition.

Now you are on stock ROM. To convert rfs to ext4 either you have to install a kernel that support ext4 and then go to recovery and then enable lagfix. Or you can go for a custom rom. My advice is to go for custom ROM like Darky...

I flash samurai kk4 kernel v1.4.3 and now phone wont boot past att screen..it will boot to recovery.....but it has all kind of mounting errors...it wont mount any partition..am i screwed and need to odin back to stock?
What kernel where you using before hand? Where you on EXT4 before?
seems like a file system problem, as PR said. going from ext4 back to the samsung proprietary filesystem causes the mounting errors because its not formatted like the kernel expects. im not sure if going from the samsung fs to ext4 causes this (i assume it would without formatting), but i know ext4 to samsung does.
I want to flash the stock v20s rom....and iti is in ext3 format right? so my question is....Can I convert it to ext4 or the rom needs to support ext4 format?

The kernel needs to support ext4. The stock kernel does not, so if you want to use ext4 you also need to flash a custom kernel.
I installed corn kernel and its running fine and I found out that it is lagfix enabled.........just one doubt ....do I need to disable lagfix before flashing any roms? if so how to disable it ....I can see rfs and ext4 in cwm what are these?
which Corn version are you running?
I run 7.0a and by default, it has no lagfix. don't need it afaik.
rfs and ext4 are different types of linux file systems that are used to store data in partitions on your phone. my phone had froyo os with rfs partitions when I bought it new. It still has rfs partitions with Corn 7.0a GB KK4.
If you are messing around with file partitions in cwm recovery, just remember that any change from rfs to ext4 will completely reformat the partition and you will lose any data on it.
If you flash ICS or JB, you are going to an ext4 file system.
goes without saying: backup everything with cwm and a backup app like titanium bu, then copy all of it to an external sd, computer or cloud. if on sd, remove it before flashing, to be safe.

I'm 7.0 A btw ......thanks for reply it was booting up pretty fastly so I thought it has lagfix enabled .....if it doesn't have lagfix then I can flash ics roms directly without problems rite
The Ext 4 is not enabled by default in the Corn Kernels.
And Yep...flash away.
