We run OCFS2 for a GroupWise 7 Post Office for about 700 users. The post office stores mailboxes (header information) as small database files (~30mb each). And individual messages as many small files (~2kb each). In total, the file system has about 1 million files in it.
We have run into some trouble when trying to preform heavy I/O operations on the file system such as a backup or file indexing (updatedb). Our solution was to do incremental hot copy of the message store to reduce load during a backup. Also, you could use snapshot technology if you have such a thing on your SAN. We have a NetApp FAS3020 and use "SnapDrive" to mount a snapshot as a volume and preform a tape backup. - Andy -- Andrew Kipp Network Administrator Velcro USA Inc.
