VERITAS File System Quick Reference

Identifying File System Types

Use the fstyp command to determine the ﬁle system type for a speciﬁed ﬁle system. This is useful when a ﬁle

system was created elsewhere and you want to know its type.

How to Identify a File System

To determine the status of mounted ﬁle systems, use the syntax:

fstyp -v special

See the following manual pages for more information about the fstyp command and its available options:

fstyp (1M)

Example

To ﬁnd out what kind of ﬁle system is on the device /dev/vx/dsk/fsvol/vol1, enter:

# fstyp -v /dev/vx/dsk/fsvol/vol1

The output indicates that the ﬁle system type is vxfs, and displays ﬁle system information similar to the

following:
