Steps to map a FileSystem to CentOS Linux Operating System.
Storage: OceanStor 5500 V3
HOST OS: CentOS 7.0
1. Need to activate the NAS functionality on the storage device by purchasing the license and upgrade the basic license to Unified;
2. A Storage Pool for File Storage Service need to be created;
3. NFS service enabled on storage and host side:
NFS Service storage: DeviceManager -> Settings -> Storage Settings -> File Storage Service -> NFS Service -> Check Enable NFSv3 -> Save
NFS Service on Host, run service nfs start command (CentOS, RedHat, SUSE).
1. Create FileSystem to OceanStor 5500 V3 -> DeviceManager -> Provisioning -> File System -> Follow the Wizard.
2. Create NFS Share -> DeviceManager -> Provisioning -> Share -> Create (button) -> follow the wizard
3. Create Logical Port -> DeviceManager -> Provisioning -> Port -> Logical Ports Tab -> Click Create -> Follow the Wizard
4. Login Host OS CLI (in this case CentOS):
a. Add in sysctl.conf following strings:
net.ipv4.tcp_wmem = 10485760 10485760 10485760
net.ipv4.tcp_rmem = 10485760 10485760 10485760
Use vi /etc/sysctl.conf command to edit the content
b. If the file is modified for the first time, run the sysctl -p command or restart the system to make the modification effective.
c. With root user run showmount -e ipaddress to view available NFS shared file systems of the storage system. (need to use the IP added to the logical port)
Ex: mount -t nfs -o vers=3,proto=tcp,rsize=1048576,wsize=1048576,hard,intr,timeo=600 192.168.28.102:/FileSystem001 /mnt
e. Run mount to verify that the NFS shared file system has been mounted to the local computer.
