I've got two servers (x-connected via gigabit-NICs) which should provide high availabilty NFS-service for a number of web/mail/something front end servers. I am currently planning on how to layout the existing disk space: a.) Multiple partitions "connected" via multiple drbd-resources (drbd0, drbd1, ...). NFS-Exports: /mnt/drbd0/ (mail), /mnt/drbd1/ (www), ... b.) One big partition on one resource (drbd0). NFS- Exports: /mnt/drbd0/mail/, /mnt/drbd0/www/, ... Possible (Dis-)Advantages: a.) Pro: Potential file system corruption only affects one partition and corresponding front end servers. Con: Not recommended in DRBD documentation. First tests show poor sync(-all) performance (as exptected). b.) Pro: Easy "DRBD-doc-recommended" setup. Con: Potential file system corruptions cause failures on all frontend servers. Total disk size on each server is ~200GB. Expected number of files: >800.000 with moderate I/O. Preferred file system is ext3. Any suggestions are welcome. H.
