[Moosefs-users] Best FileSystem for chunkers.

[wkmail <wk...@bn...>]

We are building another MFS cluster.

What is the current thought regarding File systems for Chunkers using 
older retired Opteron 250 servers (SATA2) each with 2GB RAM.

We would use Scientific Linux 6.x which defaults to EXT4 so that is the 
first thing to come to mind, but reviews are mixed.

Some really push EXT3

and since the chunkserver environment is decidedly single purpose we are 
leaning in that direction.

Note: we aren't terribly excited about XFS as we have had some issues 
with that in the past, but if someone feels strongly about it...

Sincerely,
