Security feature
|
If security is important, use blkclear to ensure that deleted
files are completely erased before the space is reused. |
Support for large files
|
If you specify the largefiles option, you can create
files larger than two gigabytes on the file system. The default option is largefiles . |
Support
for cluster file systems
|
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. |
Using Storage
Checkpoints
|
The ckpt=checkpoint_name option
mounts a Storage Checkpoint of a mounted file system that was previously created
by the fsckptadm command. |
Using databases
|
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. |
News file systems
|
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. |
Temporary file systems
|
For
a temporary file system such as /tmp , where performance is more important
than data integrity, use tmplog,mincache=tmpcache. |
Locking a file system
|
If you specify the mntlock option, you can lock a file system to disallow unmounting the file system except if the
mntunlock option is specified. The mntlock is useful for applications for which you do not want the file systems that the applications are monitoring
to be improperly unmounted by other applications or administrators. |
