Mounting {{site.data.keyword.filestorage_short}} in CentOS

{: #mountingCentOS} {: toc-content-type="tutorial"} {: toc-services=""} {: toc-completion-time="1h"}

To mount {{site.data.keyword.filestorage_full}} in CentOS, you must authorize the host first. Then, install the NFS utilities as described in Mounting {{site.data.keyword.filestorage_short}} on Linux®. {: shortdesc}

Before you begin, make sure that the host that is to access the {{site.data.keyword.filestorage_short}} volume is authorized. For more information, see Authorizing the host in the console{: ui}Authorizing the host from the CLI{: cli}Authorizing the host with Terraform{: terraform}. {: requirement}

Mounting the storage

{: #mountingStorageCentOS}

Most of the steps of mounting your {{site.data.keyword.filestorage_short}} to a CentOS host are the same as the ones that are described in Mounting {{site.data.keyword.filestorage_short}} on Linux®. However, for CentOS, you can specify some additional options by using the Options= line in the mount file. In the following example, the NFS is set to mount at /data/www.

The mount point information can be obtained from the {{site.data.keyword.filestorage_short}} Details page in the console, with an API call - SoftLayer_Network_Storage::getNetworkMountAddress(), or by looking at the ibm_storage_file resource in Terraform. {: tip}

$ cat data-www.mount
[Unit]
Description = Mount for Container Storage

[Mount]
What=<nfs_mount_point>
Where=/data/www
Type=nfs
Options=vers=4,sec=sys,noauto

[Install]
WantedBy = multi-user.target

{: codeblock}

Next, enable the mount and check that it is mounted properly.

systemctl enable --now /etc/systemd/system/data-www.mount

cluster1 ~ # mount |grep data
<nfs_mount_point> on /data/www type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.81.x.x,local_lock=none,addr=10.1.x.x)
