Filesystems

• /etc/filesystems - AIX's version of /etc/fstab. Uses stanza format, * is comment character.
• Useful commands:
  • crfs - Creates logical volume, makes filesystem on logical volume, adds entry to /etc/filesystems. Does not mount the new filesystem for you!
  • chfs - Changes settings of filesystem, logical volume, or /etc/filesystems entry.
  • rmfs - Removes filesystem, logical volume, entry from /etc/filesystems, and optionally the mount point.
• AIX itself is always installed in a VG called rootvg
• The jfs filesystem is a journaling filesystem, meaning that it keeps a summary of filesystem update information on a special LV of type jfslog
