[lustre-discuss] Fwd: ldiskfs vs zfs

[Cameron Harr]

Sudheendra,

You will get varied answers depending on who you ask. For us, we are 
strong believers in ZFS. Of course, as a major contributor to 
ZFS-on-Linux, we're heavily biased, but we believe the management 
features (snapshots, etc) outweigh any performance deficiencies compared 
to ldiskfs, especially when using SSDs. Plus, ZFS is continually landing 
major improvements that boost performance and resiliency.
