| Advanced File System (AdvFS) |
| AdvFS is a file system technology that is a replacement
for the standard "Unix File System" (ufs). It has
several improvements such as journaling, improved quotas, and disk
groups. The journaled or logging file system similar to "jfs"
in AIX or the journaled file system available in Solaris using
Online Disksuite. Journaled file systems are more resistant to
file system corruption and are much faster to check after a system
crash. |

| Logical Storage Manager (LSM) |
| There is a certain amount of overlap between AdvFS with
Polycenter and the logical storage manager. Both of these pieces
of software allow concatenated disk volumes and allow multiple "volumes"
per "volume group". But LSM provides striping and
mirroring as well. One way to think about it is that LSM operates
at the "device" level, and leaves the "filesystem"
implementation up to other software, such as "AdvFS" or "UFS".
