[CentOS] OT:Which filesystem to use with large files

2009-12-23 Thread carlopmart
Hi all, Recently I have installed a centOS 5.4 server to use as a home NAS server. I need to use large files (8GB minimum) inside of it to serve via iSCSI services. Which filesystem do you recommends me to reach maximum performance: xfs, ext3, ext4, gfs2 ?? Thanks. -- CL Martinez
