suppose i create the raid device with:

/dev/sd[abcdefgh]1
then what is the maximum size for /dev/md0?
(or more precisely after a mkfs.ext3 /dev/md0).
The /dev/sdX1 cannot be larger than 2TB. The /dev/md0 can be as big
as you like. The filesystem can be as big as your filesystem allows.
I don't think ext3 can exceed 2 TB (I could be wrong). Other
RH (e.g.) officially supports ext3 FSs up to 8TB in RHEL4.
See... I was wrong! :-)
I'm sure there is a 32bit limit somewhere, so it's probably that block
addresses are limited to 32 bits. With 4K blocks, that's 2^34 K, or
16TB.... Maybe there is some confusion with the sign bit, making it on
2^33K, or 8TB.
i already find the trivial source kernel/Documentation/filesystems/ext2.txt:
---------------------------------
Filesystem block size: 1kB 2kB 4kB 8kB
File size limit: 16GB 256GB 2048GB 2048GB
Filesystem size limit: 2047GB 8192GB 16384GB 32768GB
