How to increase the size of a database zone zoneroot storage pool on Oracle SuperCluster (Doc ID 2482275.1)

SOLUTION

In the global zone of every database domain on Oracle SuperCluster, there is a storage pool called 'zoneroot'. This provides the storage for all local database zones /root & /u01 filesystems. Over time, the available free space in zoneroot may become low e.g.

# zfs get available zoneroot
NAME      PROPERTY   VALUE  SOURCE
zoneroot  available  190M     -

# df -h zoneroot
Filesystem             Size   Used  Available Capacity  Mounted on
zoneroot               313G   313G       190M   100%    /zoneroot

Before attempting to increase the available space in zoneroot, first ensure you have package supercluster/iscsi version 2.1.0.603 (or later) installed e.g.

# pkg list supercluster/iscsi
NAME (PUBLISHER)                                  VERSION                    IFO
system/platform/supercluster/iscsi (exa-family)   0.5.11-2.6.0.1561          i--

If your version of supercluster/iscsi is earlier than 2.1.0.603, then you must update the database domains to the latest Quarterly Full Stack Download Patch (QFSDP).

You can then use the /opt/oracle.supercluster/bin/iscsi-zpool.sh command to increase the size of the zoneroot storage pool e.g.

# cd /opt/oracle.supercluster/bin
# ./iscsi-zpool.sh -h
Usage:
    To create new zpool :   ./iscsi-zpool.sh -p zfs_pool_name -s zfs_pool_size
    To increase zpool size: ./iscsi-zpool.sh -p zfs_pool_name -a size_to_add
    To destroy zpool:       ./iscsi-zpool.sh -p zfs_pool_name -d
NOTE:
    "increase" and "destroy" will only work for zpools that were created by this tool

The following example shows how to add 200G to the zoneroot storage pool.

# ./iscsi-zpool.sh -p zoneroot -a 200G

INFO: The LUN GUID of zpool zoneroot is 600144F09555F81300005C0AA5520009
INFO: The size of this LUN has been increased to: 520.00G

# zfs get available zoneroot
NAME      PROPERTY   VALUE  SOURCE
zoneroot  available  197G   -

# df -h zoneroot
Filesystem             Size   Used  Available Capacity  Mounted on
zoneroot               510G   313G       197G    62%    /zoneroot

Note that although exactly 200G is added to the iSCSI LUN on the ZFS storage appliance, you only see approximately 197G additional free space in the zoneroot filesystem. This is due to filesystem overheads.

Also note that you cannot shrink or reduce the available space in a zoneroot storage pool.
