Disable atime from the data disks (and root fs) using the noatime option during mounting of the FS.
In the /etc/fstab file, ensure that the appropriate file system has the noatime mount option specified.
LABEL=ROOT / xfs noatime 0 0
Create separate mount points for separate disk drives, and provision all of them for the scratch space. For example, yarn.nodemanager.local-dirs is a comma-separated list of local-directories that you can configure to be used for copying files during localization. The idea behind allowing multiple directories is to use multiple disks for localization. This practice helps both failover (one or a few disks going bad does not affect all containers) and load balancing (no single disk is bottlenecked with writes). Individual directories should be configured, if possible, on different local disks.
For FS creation, enable journal mode, reduce superuser block reservation from 5% to 1% for root (using the -m1 option), and use the sparse_super,dir_index,extent options (minimize number of super block backups and use b-tree indexes for directory trees, extent-based allocations).
# mkfs.xfs –t xfs –m1 –O sparse_super,dir_index,extent,has_journal /dev/sdb1
