8.5 VxFS Internal Structures Including VxFS Access Control Lists
8.6 Online JFS Features
8.7 Tuning a VxFS Filesystem
8.8 VxFS Snapshots
8.9 Navigating through Filesystems via the VFS Layer
In this chapter, we look at one of the main uses of disk and volumes : filesystems. The HP-UX kernel can support many filesystem types including Network FS, CDFS, Distributed FS, Auto FS, Cache FS, CIFS, and Loopback FS. We look at the two main filesystem types: HFS and VxFS. Understanding the structure of a filesystem can help you reap rewards when it comes to fixing filesystems, i.e., running fsck . When we run fsck and are prompted with questions regarding fixing the filesystem, we normally reply YES . This is good practice for the vast majority of situations. Understanding what fsck is asking you can lead you to make some other decisions in certain circumstances. We look at the structure of a filesystem as well as managing its many aspects. When I am talking about and creating filesystems, I use both LVM logical volumes and VxVM volumes. There are only a few instances when the commands know or care which type of filesystem is in the underlying logical disk.
