First of all thanks for the responses. You guys and gals were a lot
of help. After reading all the responses I probably will stick with
ufs instead of advfs not because of any problems associated with
advanced file systems, but mainly because there doesnt seem to be
enough of an advantage to me to warrant switching. Depending upon your
application there may be enough of an advantage.
One question I asked was I heard you shouldnt make the root
partition an advfs. The answers I got really varied from
There is no reason not to, to no dont do that. So Im still
not convinced either way there. The main reason not to seemed to
be in case of a drive failure you cant restore the root file system
unless AdvFs is running and that is tough to do on a minimal CD boot.
Advantages of advanced file systems:
------------------------------------
Speed
Ease of use for the system admin, you can extend the boundaries
of a file system over several disks.
Disk mirroring
Speed of bringing the system up after a crash
Disadvantages of advanced file systems:
------------------------------------
Seem to be a lot of I/O errors causing panics especially before
V4.0.
Once corrupted, there arent a lot of tools to repair the files, so
its often necessary to restore the file system from backups.
If your system contains a lot of small files, your system may become
full even though you have plenty of room left on your disk.
All directories are 8192 bytes which means if you have lots of
directories you need a lot of space.
If one of your disks in your domain crashes then you lose your whole
domain. So you should mirror with LSM or get a RAID solution.
