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 ....??

None of them should have a problem with large files and any differences in the filesystem metadata handling will be covered up by the underlying disk access speed of a large amount of data per file. The bigger differences are in how fast they can create or delete large numbers of files.

Thanks Les. then if I would to use sparse files to create these large files, which can be the best form: dd of qcow2 format for example??
