Dear Sérgio,
does the sub-dir limit come from OCFS2?

Dear all,
Anyone using OCFS2 on email storage system ? (postfix/qmail).
Wondering if any of you suffer any problem?! Also, what parameter did
you tune for email system only? thanks.

Hello Thomas,
We are using as general propose shared filesystem (email, shared files,
some web related files, etc...) and the only drawback from a local
filesystem is that it's a bit slower due to cluster stack.
About the tuning we have reduced the block size and pre-allocated size
to reduce the on-disk size, since email messages usually are tiny files
(lets say about 8K per message).
Our setup:
mkfs.ocfs2 -b 4096 -C 4096 -N 4 /dev/sd<X>
If you plan to use it for a large number of accounts, keep your eye on
the 32000 sub-directories limitation.
Regards,
