Support for Large File Systems and Large Files
In conjunction with VxVM, VxFS can support file systems up to 8 exabytes in size. For large
database configurations, this eliminates the need to use multiple file systems because of the size
limitations of the underlying physical devices.
Changes implemented with the VxFS Version 6 disk layout have greatly expanded file system
scalability, including support for large files. You can create or mount file systems with or without
large files by specifying either the largefiles or nolargefiles option in mkfs or mount
commands. If you specify the nolargefiles option, a file system cannot contain files 2 GB or
larger.
Usage Notes
◆ See the mount_vxfs(1M) and mkfs_vxfs(1M) manual pages for detailed information on
mounting and creating file systems.
◆ See the fsadm_vxfs(1M) manual pages for detailed information about large files.
▼ To enable large files on a file system that was created without the largefiles option
Use the fsadm command as follows:
# /opt/VRTS/bin/fsadm -F vxfs -o largefiles /mount_point
Mount Options:
◆ Enter the mount point for the file system, if you want the file system
mounted at system startup.
◆ Select the Create mount point checkbox if you want the system to
create the mount point if it does not already exist.
◆ Select the Read only and Honor setuid checkboxes, as required.
◆ Select the Add to file system table and Mount at boot checkboxes to
update the system table file and mount the file system at system
startup.
◆ To update the system table file and not mount the file system at system
startup, select Add to file sytem table checkbox and leave the Mount
at Boot checkbox unselected.
◆ To specify mount options, click Mount File System Details and
specify the appropriate options in the Mount Details dialog box.
