Veritas File System 5.1 SP1 Administrator"s Guide (5900-1499, April 2011)

Example of determining a file system's type
The following example uses the fstyp command to determine the file system type
of the /dev/vx/dsk/fsvol/vol1 device.
To determine the file system's type
◆
Use the fstyp command to determine the file system type of the device
/dev/vx/dsk/fsvol/vol1:
# 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:
vxfs version: 6 f_bsize: 8192 f_frsize: 1024 f_blocks: 1027432
f_bfree: 1026075 f_bavail: 961946 f_files: 256548 f_ffree: 256516
f_favail: 256516 f_fsid: 520114176 f_basetype: vxfs f_namemax: 254
f_magic: a501fcf5 f_featurebits: 0 f_flag: 0 f_fsindex: 7
f_size: 4194304
Resizing a file system
You can extend or shrink mounted VxFS file systems using the fsadm command.
Use the extendfs command to extend the size of an unmounted file system. A
file system using the Version 4 disk layout can be up to two terabytes in size. A
file system using the Version 5 disk layout can be up to 32 terabytes in size. A file
system using the Version 6 or later disk layout can be up to 8 exabytes in size.
The size to which a Version 5 or later disk layout file system can be increased
depends on the file system block size.
See “About disk layouts” on page 231.
See the extendfs(1M) and fsadm_vxfs(1M) manual pages.
Extending a file system using fsadm
If a VxFS file system is not large enough, you can increase its size. The size of the
file system is specified in units of 1024-byte blocks (or sectors).
The device must have enough space to contain the larger file system.
See the format(1M) manual page.
See the Veritas Volume Manager Administrator's Guide.
