to persist than write errors, such as when using non-redundant storage. mwdisable
is the default ioerror mount option for local mounts.
See the mount_vxfs(1M) manual page.
The mdisable policy
If mdisable (metadata disable) is selected, the file system is disabled if a metadata
read or write fails. However, the file system continues to operate if the failure is
confined to data extents. mdisable is the default ioerror mount option for cluster
mounts.
The largefiles|nolargefiles option
VxFS supports files larger than 2 gigabytes. The maximum file size that can be
created is 2 terabytes.
Note: Applications and utilities such as backup may experience problems if they
are not aware of large files. In such a case, create your file system without large
file capability.
See “Creating a file system with large files” on page 42.

Creating a file system with large files
To create a file system with a large file capability:
# mkfs -F vxfs -o largefiles special_device size
Specifying largefiles sets the largefiles flag. This lets the file system to hold
files that are two gigabytes or larger. This is the default option.
To clear the flag and prevent large files from being created:
# mkfs -F vxfs -o nolargefiles special_device size
The largefiles flag is persistent and stored on disk.
