To extend a Quick I/O file
1
If required, verify 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.
For Sybase, for example:
# /opt/VRTS/bin/fsadm -b newsize /mount_point
where:
■ -b is the option for changing the file size
■ newsize is the new size of the file system in bytes, kilobytes, megabytes,
blocks, or sectors
■ mount_point is the file system's mount point
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 dbfile Quick I/O file by 20MB:
$ /opt/VRTS/bin/qiomkfile -e 20M /db01/dbfile
# /opt/VRTS/bin/fsadm -b 500M /db01
An example to show how to grow VxFS file system:
/db01 to 500MB and resize the dbfile Quick I/O file to 300MB:
# /opt/VRTS/bin/fsadm -b 500M /db01
$ /opt/VRTS/bin/qiomkfile -r 300M /db01/dbfile
