Configuring Storage <strong>for</strong> <strong>Oracle</strong> <strong>Clusterware</strong> Files on a Supported Shared File System<br />

Table 4–2 Shared File System Volume Size Requirements<br />

File Types Stored<br />

<strong>Oracle</strong> <strong>Clusterware</strong> files (OCR and<br />

voting disks) with external<br />

redundancy<br />

<strong>Oracle</strong> <strong>Clusterware</strong> files (OCR and<br />

voting disks) with redundancy<br />

provided by <strong>Oracle</strong> software.<br />

Number of<br />

Volumes Volume Size<br />

1 At least 280 MB <strong>for</strong> each volume<br />

1 At least 280 MB <strong>for</strong> each volume<br />

In Table 4–2, the total required volume size is cumulative. For example, to store all<br />

<strong>Oracle</strong> <strong>Clusterware</strong> files on the shared file system with normal redundancy, you<br />

should have at least 1.3 GB of storage available over a minimum of three volumes (two<br />

separate volume locations <strong>for</strong> the OCR and OCR mirror, and one voting disk on each<br />

volume).<br />

4.3.2 Checking NFS Mount Buffer Size Parameters <strong>for</strong> <strong>Clusterware</strong><br />

If you are using NFS, then you must set the values <strong>for</strong> the NFS buffer size parameters<br />

rsize and wsize to 32768. The NFS mount options are:<br />

rw,bg,vers=3,proto=tcp,noac,<strong>for</strong>cedirectio,hard,nointr,timeo=600,rsize=32768,wsize=<br />

32768,suid<br />

Update the /etc/fstab file on each node with an entry similar to the following:<br />

nfs_server:/vol/CWfiles /u01/oracle/cwfiles nfs \<br />

rw,bg,vers=3,proto=tcp,noac,<strong>for</strong>cedirectio,hard,nointr,timeo=600,rsize=32768,wsize=<br />

32768,suid<br />

Note that mount point options are different <strong>for</strong> <strong>Oracle</strong> software binaries, <strong>Oracle</strong><br />

<strong>Clusterware</strong> files (OCR and voting disks), and data files.<br />

If you want to create a mount point <strong>for</strong> binaries only, then enter the following line <strong>for</strong> a<br />

binaries mount point:<br />

nfs_server:/vol/crshome /u01/oracle/crs nfs -yes<br />

rw,bg,vers=3,proto=tcp,noac,hard,nointr,timeo-600,rsize=32768,wsize=32768,suid<br />

<strong>Oracle</strong> Files When Used with NAS Devices" <strong>for</strong> the most current<br />

Note: Refer to your storage vendor documentation <strong>for</strong> additional<br />

4.3.3 Creating Required Directories <strong>for</strong> <strong>Oracle</strong> <strong>Clusterware</strong> Files on Shared File<br />

Systems<br />

Use the following instructions to create directories <strong>for</strong> <strong>Oracle</strong> <strong>Clusterware</strong> files. You<br />

can also configure shared file systems <strong>for</strong> the <strong>Oracle</strong> <strong>Database</strong> and recovery files.<br />
