Determining a File System's Type
You can determine a file system's type by using one of the
The FS type field in the virtual file system table (the /etc/vfstab file)
The /etc/default/fs file for local file systems
The /etc/dfs/fstypes file for NFS file systems
How to Determine a File System's Type
This procedure works whether or not the file system is mounted.
Determine a file system's type by using the grep command.
$ grep mount-point fs-table
Specifies the mount point name of the file system for which you want to know the file system type. For example, the /var directory.
Specifies the absolute path to the file system table in which to search for the file system's type. If the file system is mounted, fs-table should be /etc/mnttab. If the file system isn't mounted, fs-table should be /etc/vfstab.
Information for the mount point is displayed.
Note - If you have the raw device name of a disk slice, you
can use the fstyp command to determine a file system's type (if
the disk slice contains a file system). For more information, see fstyp(1M).
Example 17-1 Determining a File System's Type
The following example uses the /etc/vfstab file to determine the file system type
for the /export file system.
$ grep /export /etc/vfstab
/dev/dsk/c0t3d0s6 /dev/rdsk/c0t3d0s6 /export ufs 2 yes -
The following example uses the /etc/mnttab file to determine the file system type
of the currently mounted diskette. The diskette was previously mounted by vold.
$ grep floppy /etc/mnttab
/dev/diskette0 /media/floppy ufs rw,nosuid,intr,largefiles,logging,xattr,onerror=panic,dev=900002
