Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

■ You can also grow VxFS file systems online (provided the
underlying disk or volume can be extended) using the fsadm
command. You can expand the underlying volume and the
filesystem with the vxresize command.
■ You must have superuser (root) privileges to resize VxFS file
systems using the fsadm command.
■ See the fsadm_vxfs (1M) and qiomkfile (1M) manual pages for
more information.
Usage notes
The following options are available with the qiomkfile command:
Extends the file by a specified amount to allow Oracle tablespace
resizing.
-e
Increases the file to a specified size to allow Oracle tablespace resizing.-r
To extend a Quick I/O file
1
If required, ensure the underlying storage device is large enough to contain
a larger VxFS file system (see the vxassist(1M) manual page for more
information), and resize the VxFS file system using fsadm command:
2
Extend the Quick I/O file using the qiomkfile command:
$ /opt/VRTS/bin/qiomkfile -e extend_amount /mount_point/filename
or
$ /opt/VRTS/bin/qiomkfile -r newsize /mount_point/filename
An example to show how to grow VxFS file system:
/db01 to 500MB and extend the emp.dbf Quick I/O file by 20MB:
$ /opt/VRTS/bin/qiomkfile -e 20M /db01/emp.dbf
# /opt/VRTS/bin/fsadm -b 500M /db01
An example to show how to grow VxFS file system:
/db01 to 500MB and resize the emp.dbf Quick I/O file to 300MB:
$ /opt/VRTS/bin/qiomkfile -r 300M /db01/emp.dbf
# /opt/VRTS/bin/fsadm -b 500M /db01
