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

file system does not support extent attributes, has a different block size than the

source file system, or lacks free extents appropriate to satisfy the extent attribute

requirements.

The -e option takes any of the following keywords as an argument:

Issues a warning message if extent attribute information cannot be

maintained (the default)

warn

Fails the copy if extent attribute information cannot be maintainedforce

Ignores extent attribute information entirelyignore

Example of setting an extent attribute

The following example creates a file named file1 and preallocates 2 GB of disk

space for the file.

To set an extent attribute

Create the file file1:

# touch file1

Preallocate 2 GB of disk space for the file file1:

# setext -F vxfs -r 2g -f chgsize file1

Since the example specifies the -f chgsize option, VxFS immediately

incorporates the reservation into the file and updates the file’s inode with

size and block count information that is increased to include the reserved

space. Only users with root privileges can use the -f chgsize option.

Example of getting an extent attribute

The following example gets the extent atribute information of a file named file1.
