Subject Recommended mount options for ext4 datanode filesystems
Date Wed, 19 Sep 2012 05:04:56 GMT
Hi all,

We will soon be adding additional datanodes to our clusters and plan to
reevaluate our filesystem type on these servers, potentially moving to ext4
from xfs. Besides the noatime mount option, are there other generally
recommended options for mounting ext4 filesystems for use with Hadoop? With
newer Linux kernels, is nodelalloc still needed?

Thanks in advance,
-Bobby
