This paper compares the I/O performance, flexibility and ease of use features of Linux file systems; Ext4, XFS, BtrFS running on storage stack systems namely LVM and ZFS with RADOS Block Devices (RBD) as the underlying block devices as replacement to physical disks. Experiment sets that have been conducted to evaluate performance of selected file systems; Ext4, XFS, BtrFS and ZFS are presented and the result is also discussed. Useful features in terms of flexibility and ease of use for each file systems are also included and compared.
