Installing the Optional OnlineJFS Product
HP OnlineJFS is the advanced optional bundle for the VxFS File System.
You can use the capabilities of OnlineJFS to perform certain key
administrative tasks on mounted VxFS file systems. Because you can
perform these tasks on mounted file systems, users on the system can
continue to perform their work uninterrupted.
These tasks include:
• Defragmenting a file system to regain performance.
• Resizing a file system.
• Creating a snapshot file system for backup purposes.
You can install it with swinstall in the following order:
1. Install the JournalFS product, if it is not already installed.
2. Install two HP OnlineJFS bundle filesets.
(AdvJournalFS.VXFS-ADV-KRN and
AdvJournalFS.VXFS-ADV-RUN).
During the install, swinstall will edit the /stand/system file, rebuild
the kernel, and reboot the system to bring the new kernel libraries into
memory.
For more information about installing and using VxFS and HP
OnlineJFS, see the manual HP-UX System Administration Tasks,
