I've a question about the max. ext3 FS size. The ext3 FAQ explains that
the limit is 4TB.
Hm, strange: I'm pretty sure that mkfs.ext3 understands bigger
blocksizes for quite a while now. Then again, the FAQ says
"Version: 2004-10-14"...
So, although I'd really love to have this information (and the FAQ!) on
http://e2fsprogs.sf.net/ this is what I found:
blocksize file size limit filesystem size limit
1 KiB 16448 MiB (~ 16 GiB) 2048 GiB (= 2 TiB)
2 KiB 256 GiB 8192 GiB (= 8 TiB)
4 KiB 2048 GiB (= 2 TiB) 16384 GiB (= 16 TiB)
8 KiB 65568 GiB (~ 64 TiB) 32768 GiB (= 32 TiB)
Note that an 8 KiB blocksize is only supported on systems with 8 KiB
pagesize (i.e. linux/alpha).
So, it really looks like 16TiB shouldn't be a problem...but I just
stumbled over this:

While the ext* gurus are busy on the ext4 list, I too would appreciate
a comment on the current limitation of ext2/ext3/ext4, so that we can
update the FAQ. These questions really come up way too often...
Thanks,
Christian.
