The Services Unit
A dumping ground for various useful bits of info - mainly for us, but occasionally for others. For older stuff, see the earlier, pre-wiki
Service Unit info page.
We take it in turns to be the front-line Support contact,
RT Guy. This honour rotates weekly on an alphabetical basis: Craig, Gordon, Neil, Roger.
Operational Stuff
Servers
The Services Unit is currently responsible for 58 machines, of which 47 include the <dice/options/server.h> header, and 11 the <dice/options/small-server.h> header. Of these machines, 15 are AFS servers:
- cetus, cockatrice, crocotta, gorgon, hawthorn, kraken, lammasu, minotaur, mullo, naga, nessie, pyrolisk, squonk, telford (not Services, MPU), unicorn, yeti
We also started keeping a note of
server status and availability, but this appears to have fallen by the wayside.
We have a checklist from the last
servers OS upgrade.
Hardware
Filespace & Backups
As listed above, we currently have 15 AFS servers (excluding the VM afsdb stand-in server), providing RW, RO, & BK volumes. A list (of all configured AFS servers, whether currently serving volumes or not) can be generated from the command-line using:
vos listaddrs
For servers with active volumes, use:
vos listvldb | awk '$1 ~ /server/ {print $2}'
(this currently gives the same list as above, but without crocotta).
Our
backups are managed via TiBS, using the
eponymous component (with notes on its
development and
full implementation).
Additionally, there are notes on
configuration and use, plus
NFS partititions (OLD) that may or may not still need adding.
The
TiBS 2109 manual is also available, as are additional notes on TiBS
configuration files and a snapshot of
self-managed backups.
AFS
In addition to the
servers mentioned above, we have notes on:
Printing
There are notes on
CUPS configuration and problem-solving, plus notes on the more recent
CUPS in Appleton Tower and general
CUPS printing admin.
There's also a list of
known printing problems that may be useful (OLD), and some
fixes (OLD).
Additionally, there is
Information on the Xerox MFDs (2012), plus
scanning information and details of
E-financials printing.
Web
Meetings, Timekeeping, & Projects
- All our meeting notes and minutes can be found on the Unit Meetings page. Unit meetings are usually held fortnightly, with individual meetings in between.
- Neil's Time-keeping page describes his time-analysis script, and lists current "buckets"
Policy Statements, and lists of Things To Do
Current Tasks
We also maintain a
list of jobs we're currently looking at, plus
some
smaller projects.
