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.
See Quick I/O for Databases.

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 .
