[NOTE: There is important information hidden throughout this note,
please read *ALL* of it!]

Wuarchive.wustl.edu will be down Tuesday, Wednesday and Thursday, June
15th through 17th to install a new disk drive.  During this downtime we
will also be committing wuarchive to the OSF/1 operating system.  This
downtime is part of a continuing program to enhance the services
offered by wuarchive, which is supported in part by a grant from the
National Science Foundation.

As part of the downtime, we will be combining all of the archive disks
(/archive, /archive/decus, /archive/usenet, /archive/systems and
/archive/mirrors*) into a single 14.6 gigabyte logical volume.  This
will have a number of positive benefits, including:

   o  A Single NFS mount point to access the entire archives, rather
      than nine.

   o  All free space will be combined, leading to less wasted space.

   o  Disk striping may be enabled when it is available, permitting
      really massive I/O performance.

   o  /mirrors* will no longer be necessary.

The reason wuarchive will be down so long is that it will be necessary
to backup the entire system, create and initialize the logical volume
and then restore the backup.  It takes quite a long time to create a
backup of 11-something gigabytes of data, and even longer to restore
it.

As noted above, the archives currently consists of eight disk drives.
Each disk drive must be mounted as a particular part of the directory
structure.  For example, one disk is mounted as /archive/mirrors.  By
going to a single logical volume, it will no longer be necessary to
have the various /archive/mirrors directories.  IN THE TWO WEEKS AFTER
THE DOWNTIME, ALL OF THE /MIRRORS DIRECTORIES WILL DISAPPEAR.  All of
the material in the mirrors directories will be placed into the
/systems hierarchy, which will be slightly reorganized to accommodate
all of the new information.

This downtime will affect all services offered by wuarchive:

   o Anonymous FTP access,

   o FSP access,

   o NFS access,

     IMPORTANT: YOU MUST DISMOUNT *ALL* ARCHIVE PARTITIONS BEFORE THE
                DOWNTIME BEGINS:

		/archive
		/archive/usenet
		/archive/systems
		/archive/mirrors
		/archive/mirrors2
		/archive/mirrors3
		/archive/mirrors4

   o Nameservice

   o All e-mail going to/passing through wuarchive will be delayed.
