OK so I went back to RHEL 2.1 circa 2003 with kernel 2.4.9 and e2fsprogs feb 2002. By default the installer uses ext3 with a 4KiB block size.
'mke2fs /dev/hdb' results in ext2 with 4KiB block size, so that's the default for ~13 years. However, I was allowed to format with blocksize 1KiB and I could read and write to it. But I can't think of any reason why you'd do this on purpose.
CentOS 4.0 4, February 2005. Uses Linux kernel 2.6.9-5. It will not let me mke2fs -b 1024, I get a "bad block size" error. And 4.0 through 4.8, parted starts partition 1 at LBA 63, so I'm going to hope/guess this fixed by CentOS 5 released in 2007. I know it's fixed by CentOS 6 in 2010. -- Chris Murphy -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
