Re: [ldm-users] high memory

Has anyone tried mounting ext3 with the data=writeback option (with the risk that active data files could be corrupt after a crash)? I'm wondering how close performance would come to ext2...

The choices for files of this size are ext2 if you don't care about journaling, or XFS. XFS has its own share of problems but does work very well.

We switched off of ext3 for our data partitions for high speed IO. It blows chunks compared to ext2. You loose journaling but I don't care. I don't have long term storage.

Jeff,
If your disk RPM isn't at least 7200, your I/O is going to be bad with Level2/3 feeds.
