[9fans] Beginner question on how to change owner of files in fossil

[plan9]

Hi,

some time ago I upgraded my machines from kfs to fossil/venti using
the homegrown kernel (as described on the wiki page, this was before
the fossil/conf times) that uses a fossil without srv -AWP support.
In order to do a pull from sources, I created a special admin user,
who is a member of the sys group.

So, obviously, lots of new files that I have pulled subsequently are
now owned by my admin user.  And this leads to those annoying "cannot
change attributes" messages during pulls.  I have now rebuilt my
kernel using the latest, greatest fossil.

What is the most straightforward way of reverting all files owned by
my admin user to sys?  I have so far attempted doing just a pull, this
has no effect, bar giving me the usual warning.  I have attempted a
pull -s, which has absolutely no effect whatsoever, doesn't pull
anything as far as I can tell.  I have attempted removing the
offending files, but a pull only reports that it won't update "locally
removed files", and an explicit pull -s of an explicit deleted file
has no effect at all (again).

Any ideas?

Do I have to build a special purpose fossil that allows srv -AWPp?

Thank you very much in advance,
Robby

PS I am having difficulties using the pcf and pccpuf kernels, but I
   haven't yet played around enough to figure out what I might be doing
   wrong.  I just get a screen full of lots of 80...=something and a dump
   of the registers.  I'll play some more.

use the -AWP /srv/replica and just chmod there..  you can look at
/dist/replica/client/plan9.log for ownership information or,
alternatively, look at /n/sources/plan9/...

with plan9.log you can script it quite easily -- it has original
user/group for every file you've pulled...

Hi,

As far as I can tell, chmod does not support changing the owner of a
file.  I know I could do it by building a special fossil to allow srv
-AWPp and then use '[ fsys name ] wstat file elem uid gid perm length'
inside a con.

Is there any immediately usable command similar to chown for use on a
srv -AWP mounted tree?

Thanks,
Robby

Aha! Excellent. Can't really see how I missed that.

I'm pretty sure lookman owner didn't list that on Sunday.  Probably
selective vision, or something.  Apols for the noise.

[9fans] install w/Smart Array 3200

[Eric KD5UWL]

Hi,

So far I've only installed Plan 9 on IDE machines.

But now I have 3 Compaq proliant ML 570 machines that I'd like to install
it on.

The problem I am having is that I can't see the LUNs presented by the RAID
controller (Smart Array 3200) -- the only device the installer sees is the
CD ROM :(

Any ideas how I can build an install floppy image that will see my RAID
controllers?

Thanks,
Eric

Hi,

Hope this wasn't a stupid question -- ?

Hi,

with not having actually tested mine I didn't want to hazard a guess until someone else tried

here's the news you probably don't want :

I have FreeBSD installed on my 1600 proliant though it is due to come out of the co-lo soon 

dmesg reports the SMART as
ida0: <Compaq SMART-2SL array controller> port 0x3000-0x30ff mem 0xb8000000-0xbfffffff,0xc6ffff00-0xc6ffffff irq 11 at device 0.0 on pci2
ida0: drives=1 firm_rev=4.48
idad0: <Compaq Logical Drive> on ida0
idad0: 8673MB (17764320 sectors), blocksize=512


and looking in the kernel conf
device          ida             # Compaq Smart RAID

means that it is specialised so for it to work in plan9 someone will have to write a driver for it

The code for it is available and is under the BSD license

%pwd
/usr/src/sys/dev/ida
%ls -l

If you don't have a FBSD handy it's in CVS

Hi,

Thanks, Matt -- and you are right -- not exactly what I wanted to hear.
These boxes do have ncr scsi controllers in addition to the raid.  I have
some sun D1000 arrays (just boxes of scsi disks - no hw raid) I could drag
over there and use, or just use these machines as CPU servers.

I do have redhat on one of these machines and do see similar info about
the device and its driver...thanks for sharing the output of yours.

I haven't written a device driver since I rewrote the keyboard and video
drivers for my trs80 in 1979 .. and that was in z80 assembler...guess
there's no better time than the present to try another ...

Looks like I have some nice CPU servers in the meantime :)

Thanks to all,
Eric

Re: [9fans] install w/Smart Array 3200

[Martin Harriss]

If you go to http://sourceforge.net/projects/cpqarray you can find the 
specification for the Smart Array 3200 (and similar controllers.)

It doesn't look *too* bad - probably not more complex than a driver for 
ATA disks.  But I havn't looked at it too closely.

73 and Good Luck,
Martin
