I've a question about the max. ext3 FS size. The ext3 FAQ explains that

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).
Is this still true? 8KiB pagefile only on linux/alpha? We run RHEL4-AS
x64_86 on AMD Opteron, and the OS is going to let me create the 8192
block size on a 9TB partition, but it's giving a warning:
partition is: Disk geometry for /dev/sda: 0.000-9296872.000 megabytes
[root@dudemiestro ~]# mkfs.ext3 -b 8192 -m 1 /dev/sda1
Warning: blocksize 8192 not usable on most systems.
mke2fs 1.35 (28-Feb-2004)
mkfs.ext3: 8192-byte blocks too big for system (max 4096)
Proceed anyway? (y,n)
Anyone do this before and had any kind of success?
Thanks,
Alex
