Managing File Systems
Chapter 6650
In an NFS environment, tell users of other systems that they can
remount the file systems to their systems.
After you have verified that the new JFS file systems are accessible, you
can remove the /etc/fstab.save file and edit the /etc/fstab file to
remove the commented out lines.
For more information on the commands used in this procedure, see cpio
(1), fbackup (1M), frecover (1M), fstab (4), lvcreate (1M), mount_vxfs (1M),
mkfs_vxfs (1M), shutdown (1M), and tar (1).
Method 3: Converting from HFS to JFS Using vxfsconvert
Use this method to convert an HFS file system to a JFS file system when
you want automatic ACL conversion (if you have no incompatible ACLs).
WARNING Do not use vxfsconvert without doing a complete backup of your
file system. vxfsconvert is not guaranteed to work on every file
system. If the conversion should fail, you will lose your data if
you don’t have a backup copy.
NOTE vxfsconvert converts HFS access control list (ACL) entries to JFS ACL
entries. However, only the entries that comply with the POSIX ACL
standard are converted. The compliant entries are those that specify
permissions for either a user or a group, but not both. For example,
entries of format ( user .%) and (%. group ) will be converted, while entries
of format ( user.group ) will be omitted. For files with both supported and
unsupported entries, all supported entries will be converted, but
unsupported entries will be omitted. If the HFS file system you are
converting contains unsupported entries, you must write a script to find
and convert such entries to supported entries, so that vxfsconvert will
convert them to JFS ACLs.
Step 1. In an NFS environment, tell remote users to unmount the affected file
systems to avoid having stale NFS mounts later.
Step 2. Unmount the HFS file system. For example:
umount /opt
