system use the vxupgrade command as described in step 8. You must run fsck after
vxfsconvert as vxfsconvert does not create all metadata files.
8. To run the VxFS-specific full fsck on the converted file system, enter the following:
# fsck -F vxfs -y -o full <vol_name>
During pass 4, fsck displays several error messages that require a yes response to
complete the conversion process.
9. VxFS file systems with disk layout 4 can still be mounted with VxFS 5.0. However, to
upgrade to disk layout versions 5, 6, or 7, use vxupgrade as follows:
a. To upgrade a mounted VxFS file system from disk layout 4 to disk layout 5
# vxupgrade -n 5 <mount_point>
b. To upgrade a mounted VxFS file system from disk layout 4 to disk layout 6
# vxupgrade -n 5 <mount_point>
# vxupgrade -n 6 <mount_point>
c. To upgrade a mounted VxFS file system from disk layout 4 to disk layout 7
# vxupgrade -n 5 <mount_point>
# vxupgrade -n 6 <mount_point>
# vxupgrade -n 7 <mount_point>
10. To verify the conversion, enter the following:
# fstyp -v <vol_name>
Access Control Lists
An Access Control List (ACL) stores a series of entries that identify specific users or groups and
their access privileges for a directory or file. A file may have its own ACL or may share an ACL
with other files. ACLs have the advantage of specifying detailed access permissions for multiple
users and groups.
File systems created with the Version 5, 6, or 7 disk layouts, up to 1024 ACL entries can be
specified. ACLs are also supported on cluster file systems. See the getacl(1) and setacl(1) manual
pages.
NOTE: only available for disk layout 4 and above.
