PLEASE!!!! Be more specific. There are many term versions out now, and especially starting with term version 2.0.0 many things have been changed.

So please state the term version you are using, are you using it in shared or non-shared mode, is root running term or a user, what clients did you try to start. Send any information you think we need to help you. That way you make sure we have a possibility to help you.

Please do not post questions to comp.os.linux.misc - read on for details of
which groups you should read and post to.

Please do not crosspost anything between different groups of the comp.os.linux
hierarchy.  See Matt Welsh's introduction to the hierarchy, posted weekly.

If you have a question about Linux you should get and read the Linux Frequently
Asked Questions with Answers list from sunsite.unc.edu, in /pub/Linux/docs, or
from another Linux FTP site.  It is also posted periodically to c.o.l.announce.

In particular, read the question `You still haven't answered my question!'
The FAQ will refer you to the Linux HOWTOs (more detailed descriptions of
particular topics) found in the HOWTO directory in the same place.

Then you should consider posting to comp.os.linux.help - not
comp.os.linux.misc.

Note that X Windows related questions should go to comp.windows.x.i386unix, and
that non-Linux-specific Unix questions should go to comp.unix.questions.
Please read the FAQs for these groups before posting - look on rtfm.mit.edu in
/pub/usenet/news.answers/Intel-Unix-X-faq and .../unix-faq.

Only if you have a posting that is not more appropriate for one of the other
Linux groups - ie it is not a question, not about the future development of
Linux, not an announcement or bug report and not about system administration -
should you post to comp.os.linux.misc.

Subject: Suggest:SCSI Tape File System
Date: 14 Aug 1994 02:20:00 GMT

I have been pondering a bit and have worked out a reasonable way to allow
a mountable file system for high speed tapes. 

 BUT   -  Has it been done for LINUX ?

If not (and I have looked) - this is my proposal : that a modified ext2 
file system be made with the following attributes :
(Note Primary is SMALL+HIGH SPEED, Secondary is LARGE+SLOW SPEED)

        1. Allows the directory entry portion to be stored on a primary 
           block device to the actual data. Of course there could only
           be 1 for each. Only entries of a normal data type would be
           redirected to tape - or alternately and in a totally non-standard
           fashion implement a new 'offline' bit for files stored on the
           secondary device. The aim is to ensure directories, devices and
           named pipes are not redirected to the secondary device.

        2. Upon initially mounting the device - the entire directory
           structure is loaded onto the primary block device from the
           secondary block device.

        3. Upon unmounting the device - the entire directory structure is
           stored from the primary block device onto the secondary block
           device.

        4. During idle time directory changes on the primary device
           are reflected to the secondary device.

(*)Also a block scsi tape device needs to be created to allow "random"
 access to the tape device. This device is stbn standing for SCSI Tape
 Block number 'n'.

The aim of this is as follows :

   Create for example a ext2new partition as /dev/hda4(primary 4Meg)
   /dev/stb0(secondary 2Gig) allowing a large file system accessible
   drive to be created for archival purposes.

My immediate problems are :
1. I only started on Linux 6 weeks ago.
2. I only have one drive subsystem (IDE) so testing is impossible.
3. I NEED HELP.

If anyone is interested give me an email, if not I'll still be working
on it just for the fun of it.

PS : This idea is modelled on the idea of similar products for DOS which
store the directory information as a DOS file and the data on either indexed
floppies or tape.

The manual for the FERRUPS series is Best TIP # 503 (Technical
Information Publication). I don't know the TIP # for the Fortress,
although I imagine the details are similar.

The manual is about 30 pages, with complete descriptions of all signals,
such as which pins close/open on alarm, that are available on the DB25
port as well as the complete RS232 interface description.  You need a
special cable to use these, but they are documented.

As to the communication interface, the manual also describes BOTH the
commands and responses available via a terminal as well as the 'Format'
mode, which transmits an 80 character status line every 15 seconds.

All I did was ask for the manual. I did install a 18KVA and a 7KVA
FERRUPS, but haven't the time to interface them yet.

Well, when you buy a distribution that has the entire directory tree
on it in non-compressed form, you can save quite some harddisk space
by keeping the CD mounted all the time, and setting up some symlinks to
subtrees which you don't use so often.

This will allow you to have a full installation on, say, a 200M disk and
still have space for your own files.

Now try that with a tapedrive :-)

(of course I have both a CD-ROM drive and a tape drive...)

You're right... you need to write a driver.
But usually the manufacturers are so proud of their clever scheme to use
a printer port to control a tape unit, that they won't tell you how it
works...

Disk-to-disk copies with disk swapping is currently not available for
Linux, I think.  You could write a program to do it, but it would not
be possible to do it on the only disk in the system.
Of course you could boot from floppy for the purpose of performing the
backup, when you make a bootfloppy with this special diskcopy program
on it.

When you want to write it, it is probably easier to do it on the sector
level (just as DOS is doing) than on the file level.
You could also setup swapspace on the IDE disk (e.g. in a DOS file) and
thereby expand the number of bytes you can transfer in a single swap.

   You may never have worked in a large corporate environment, but
from my experiences as a database consultant, I'd say that most
workstation-based environments only have tape drives on one out of
10-20 machines, if you're lucky.  Recently, I've been seeing Sun
installations where there are 10-20 cd rom drives in the site, but
only 2-3 machines with tape drives. (these are 100-200 sun
workstation sites.)  If you've got 120 IPXes, the additional $500
for a qic tape drive adds up frighteningly quickly.

                 ____

                  \/  and kicking the user off until the install was done.

No, I'm working in a _large_ international research institute, which
has about 2000 Unix workstations. Putting a tape drive on each one
would cost 1 M$, which is a bit more than nil, especially when you
have a big tape robot connected to an IBM 9000 mainframe.

Small businesses and large organizations are quite different, you know :-)
