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 disk layout can be up
to 256 terabytes in size. The size to which a Version 5 or Version 6 disk layout file system can
be increased depends on the file system block size (as shown in the tables under "VxFS
Version5 Disk Layout" on page 208 and "VxFS Version 6 Disk Layout" on page 209). See the
following manual pages for more information about resizing file systems:
• extendfs(1M)
• fsadm_vxfs(1M)
How to Extend 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).
NOTE If a file system is full, busy, or too fragmented, the resize operation may fail.
To extend a VxFS file system, use the syntax:
fsadm [-F vxfs] [-b newsize] [-r rawdev] mount_point
vxfs The file system type.
