Hi,
ext3 filesystem has 32-bit block address and ext4 filesystem has
48-bit block address. If a user installs ext4, how will the file
system handle already existing block with 32 bit values?
Why should it ?
thats what ext3 is for.
your kernel can have both FS's supported, and would use ext3 drivers for
ext3
filesystems its asked to mount.
Id expect ext4 drivers handling ext3 filesystems is a distant, secondary
goal
to getting a fast, reliable, clean 48bit filesystem working.
Can anyone point me to the correct pointer for this backward
compatibility stuff? I searched for it but cudn't find much info. Is
the work still pending on this front?
Thanks,
KL
