Hi,I'm only asking, I'll migrate from old server to a new one. If are there a better filesystems (with a dissaster recovery -emails are VERY important for users), it is a time and place to migrate. Now, on HP DL380G, we've sometimes high waits of processes, 3500 mail users on 300GB SCSI mirrored disk. Also we use SAN storage, synchronized by rsync. SAN storage is now only for copy, on the new server we plan to use it actively. That's why I asking too - is Reiser on SAN good ? Or ZFS ? Or EXT4 ? And it's disaster recovery (repairing filesystem)...
Thanks J.K. Cituji Eero Hänninen <fax@xxxxxxxx>:

But couldn't be better ? :)I have time to time bad experiences with ReiserFS 3.6. Soon or latter some data corruption happens, and if reiser becomes broken then its broken after repair too. May be its kernel related or my personal problem. Currently our old mail infra is using xfs and ext4, and it seems work fine with our load. XFS needs careful tuning before it gets perform like on creation log size, block size etc, and on mounting increase logbufs to 8 (default 1). And of course don't forget increase number of inodes. Future plan is change hardware and mail system architecture, so we move to ZFS (on FreeBSD) , as current stress tests shows good results on test servers. But lets see how it will be work with about 1.2m users real work load. About Your thread, why you are asking, just for sure that you have made good choice or you have some kind performance problems? :) Best Regards, Eero ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
