Not for growing a pseudo-worm.  You need to expand
the bitmaps at the beginning of the disk.

Funny you should ask - last weekend I took my brain out the box where
it's been hiding for 6 months, dusted it off and set it back onto the
fileserver problem. Then came Monday and back to the administrivia...

A lot has changed in the meantime so it's almost like starting from scratch.
I appreciate the offer of help, if something comes up that doesn't rely on
having our current environemnt I'll let you know.

Cool, thanks Nemo.  btw- on a related note, can anyone at the labs
comment on how the recent economic situation has affected the various
fileserver work currently in progress?  Is there anything that the
community can do to help out?

If forsyth finds out where he had the code to grow I'm willing to
merge it into the ide patch for the fs kernel. At least, that
would let us grow before something better gets integrated (?)
into the official fs code.

It'd be really nice if, instead of a special kernel, I could do
this from a standalone terminal with a small suite of tools designed
to manipulate file server disk images.  Particularly nice would be
the ability to do copies from one *worm volume to another (resizing
as needed), and the ability to delete old files from a pseudo-worm
(cf, to combat the undergraduate student who downloads 20 gigs of
porn or `WaReZ' or something and fills up a significant percentage
of the department's dump space).

Wouldn't a ream on the target device followed by a raw copy of
the source into the target work?

you can concatenate the new device on the end, but if
it's a pseudo-worm (f) you'll need to run a special kernel
to initialise it first.  it can normally be initialised only by ream,
but of course you don't want to do that.  i've probably got
the code to do it somewhere since i've done it several times.

I think you just have to copy the old device into the
bigger one; the fs kernel would note a resize and simply
adjust the new limits and keep on burning the worm.

However, since I tried with two disks of the same size and
they were ide, I'd wait for  acks/nacks from others.

okay, so i've got this file server. given my
space and money constraints, it's a pseudo-worm,
running off a single 36GB SCSI disk. said disk is
nearing capacity.

as one might imagine, i'd like to add capacity to
my file server. how do i do so? i'm particularly
interested in how to do so without loss of all my
history, and, if possible, without wasting a disk
of size equal to my current fs.

i've heard tell on this list of people upgrading
file servers, changing jukeboxes and retaining the
history, and so on. the common response seems to
be "it's not too hard." great. so please describe
the procedure to someone interested in doing it.

the above is a hypothetical question. i do actually
have the disk and box, but havn't set up the file
server yet. i want to know the process for upgrades
before i set up my file server with _any_ set size
for storage. so... anyone?
