This is true but since writes are only confirmed when written to the remote node by drbd, there is no performance advantage surely since both boxes have to write the same amount of data in one operation for that operation to be declared complete. We're using NFS to export these volumes, I guess we could in theory have two VIPs and so share the load but I doubt its necessary... > Aside: make sure you're happy with your decision to use reiserfs. and > But I don't want to restart the old "reiserfs vs everything and >From the other side: although ext3 is robust...... well this is indeed a thorny issue. On our own NAS boxes we build we always use XFS since we've shown performance advantages and XFS seems suited to backup files (ie very large files). I note that a number of "proprietary" NAS boxes available today (eg Adaptec Snap servers) also use XFS... The plan was to use XFS until a) one of the backup solutions we looked at only supported ext3/reiser b) I read somewhere that XFS is not suited to lots of small files and reiser is we're using this storage for maildir boxes so lots of small files. Since pobox.com knows something about email ;) I'd appreciate a heads up. Since you said "your employer suffered data loss" - would that be pobox.com and what do you use now instead ?
