[Ocfs2-users] How to overcome 32000 subdirs limit

[Sergey Bolbat]

Thank you for the answer.
I've updated kernel to .32 and now it's time to install OCFS2 tools 1.6.3.
I've downloaded this source:
http://oss.oracle.com/projects/ocfs2-tools/dist/files/source/v1.6/ocfs2-tools-1.6.3.tar.gz
What do you say about that? It should be better to wait until ocfs2 tools
1.6.3 for Debian will appear (there is only 1.4.1-1 for Debian:
http://packages.debian.org/lenny/ocfs2-tools) or it should be better to
compile it from the source?
And by the way, when I'll install 1.6.3, should I update any options for my
storage FS for indexed dirs to work?

Thanks.
