Run the following command to set execute permissions for the nytro set affinity script:
# chmod +x /etc/init.d/nytrolin_set_affinity.sh
2.
On the Linux operating system, run the following Nytro Linux Driver set affinity script:
# /etc/init.d/nytrolin_set_affinity.sh
3.
Add this script to the
/etc/rc.local
to make sure that this script runs on each system reboot.
4.
Make sure the partitions on the Nytro device align to 1-MB drive offset using
sfdisk
utility. Refer to the
sfdisk

Example:
To create a 1MB-aligned partition of the entire disk capacity
# echo "2048,," | sfdisk -uS /dev/nytro-sda --force

File System Configuration
Use the XFS file system for low-latency and use the following command to format the drive partition for the XFS file
system:
mkfs.xfs <nytro-device-partition>
Example:
# mkfs.xfs /dev/nytro-sda2
Use the following options to mount the XFS file system:
mount -o nobarrier,noatime,nodiratime <nytro-dev-partition> <mount-point>
Example:
# mount -o nobarrier,noatime,nodiratime /dev/nytro-sda1 /nytro-xh6451
