Veritas File System 5.0 Administrator's Guide (September 2006)
If you specify the cluster option, the file system is mounted in
shared mode. Cluster file systems depend on several other Veritas
products that must be correctly configured before a complete
clustering environment is enabled.
Support for cluster file
systems
The ckpt=checkpoint_name option mounts a Storage
Checkpoint of a mounted file system that was previously created
by the fsckptadm command.
Using Storage
Checkpoints
If you are using databases with VxFS and if you have installed a
license key for the Veritas Quick I/O for Databases feature, the
mount command enables Quick I/O by default (the same as
specifying the qio option). The noqio option disables Quick I/O.
If you do not have Quick I/O, mount ignores the qio option.
Alternatively, you can increase database performance using the
mount option convosync=direct, which utilizes direct I/O.
Using databases
If you are using cnews, use delaylog (or
tmplog),mincache=closesync because cnews does an fsync()
on each news file before marking it received. The fsync() is
performed synchronously as required, but other options are
delayed.
News file systems
For a temporary file system such as /tmp, where performance is
more important than data integrity, use
tmplog,mincache=tmpcache.
Temporary file
systems
See the fstab(4), fsckptadm(1M), mount(1M), and mount_vxfs(1M) manual pages.
Example of mounting a file system
The following example mounts the file system /dev/vx/dsk/fsvol/vol1 on the
/ext directory with read/write access and delayed logging.
To mount the file system
◆
Mount the file system:
# mount -F vxfs -o delaylog /dev/vx/dsk/fsvol/vol1 /ext
Editing the fstab file
You can edit the /etc/fstab file to mount a file system automatically at boot
time.
You must specify the following:
