Unionfs stores the entire copies of the files. So, if you are going to be writing to all 30 files, and each is going to be 512MB, then you will not have enough space. I'd go with something logrotate-like, where each night you create a new file, and move the old one to the disk. Then, if you want to get the full log, just concatinate all the daily logs into one. I hope this helps, Josef "Jeff" Sipek. -- UNIX is user-friendly ... it's just selective about who it's friends are _______________________________________________ unionfs mailing list [email protected] http://www.fsl.cs.sunysb.edu/mailman/listinfo/unionfs
