Hello,
I tried to patch the kernel with accounting and quota support.
Everything seems to be Ok but I'm not sure I can trust on quota since
the patch was for an older version of the kernel (mine is 1.2.13) and I had
to patch by hand (open.c.rej). Have someone out there used the quota for a long
time on a linux box with no problem ? Can I trust or I'd better turning
it off ?

Ciao,
Nico

It's reliable, at leat for my linux box.  I've been using quota for 4
months and never encounter any problem with it (there are 8 user accounts
in it).  I grabbed a pre-patched kernel 1.2.13 for a ftp site which I
can't remeber its addess from my head now.  If you need it mail me and
I'll send it to you.  Oh..., I can put it in my ftp site:
ftp://celab3.ce.arizona.edu/pub/linux-kernel-with-quota/

We are an ISP using linux and happen to be the home site of the quota
developers (marco and ed). We couldn't live without quota.
Our account machine runs 1.2.13 (+ strace patch) & quota.
works like a charm for over 6 months now.

At our site you can find patches and complete kernels for
quota

ftp.cistron.nl:/pub/os/linux/kernel/v1.3 or v1.2

Good luck,

I tried those patches for 1.2.13, too, and they completely suck with NFS!
Namely, copying file to NFS-mounted partition with quotas enabled (on the
server, of course) make no changes to quota usage, i.e. given I have 10 MB
disk usage, after copying & and deleting a 1MB file 10 times `quota' tells
I'm using 0 blocks!

Exactly.

Quote:>Instead of your "*" reply,

May be it was childish - ok; but it's not more "*" than saying somehting
"works like charm" based on single person (==box) expirience.

I intended to do so; but here came your followup (just on the day I tried new
quotas). So, I thought it's the same 'cause you're from the same (linux!)
site.

BTW, as we "couldn't live without quota", too, I switched back to quotas-1.33.

Over NFS?

Hmm, it looks strange.

The point is authors of quota should have their newsreadres tuned to hot
any *quota*-containing messages; if you insist I'm wrong I'll send this stuff
directly by email.

Quote:>We are developers for linux on more than one front.

I'm maintaining bunch (>10) of linux boxes mounting 20+ users' home dirs from
NFS server (linux, too), so I'm serious about quotas either.

Quote:>>BTW, as we "couldn't live without quota", too, I switched back to quotas-1.33.
>?? which version ? We are still using 1.2.pre14 (13 with strace patch)

Server is 1.2.13+kswap; clients are 1.2.1, 1.2.10, 1.2.13+kswap

Quote:>We are currently running 1.3.34 on our news server (without quota).

As I said before, the problem is with NFS; being on the server side, the quota
seemed to work ok.

Everytime linus makes a new kernel version we try and send him a new diff.
Last time he wanted some changes which were made in a few days.
Since then i havent heard from linus about quota.

Really, we tried a _LOT_ of times but for some reason he wont put them
in. In the mean time, you can get both complete kernel sources and
the patches from our site ...

I've been running the 1.3.35 with quota for a few days.  The quota
part is okay but I managed to crash the kernel with a run away process.
All I did was try quotachk.  It is slackware 2.2.  I think I will
try kernel 1.3.32 which is reported to be a bit more stable. Crash?
What a mess.  But 1.3.xx kernels are so nice otherwise. It is hard
to resist. :-)

Last time I heard Linus talk about this (in the linux-kernel mailing
list) he told that the quota pathces weren't stable enough...

1.3.x kernels are development kernels anyway. They aren't supposed to be
stable but to help to develop new uitlities like quota.
You would me, the author (marco) and a lot of other people a great
pleasure by downloading the patches, apply them and report BUGS so we
can fix them in order to make them better/faster/cleaner ..
Isn't this the general idea about linux development in general ????

Danny

        The linux quota patches have some bugs in them.  I dunno if this is
just with my system, or if it has a problem scaling, or what..

        I've got a p66 w/ a 4 gigs of disk, and 1 gig of that is quotaized.
Perodically users report that they have 200k of files, and it says that they
have over their 3MB quota.  There are roughly 3000 users on this filesystem,
and i've got them set up with *group* quotas.

        This is an instability that needs to be figured out by the author,
and I'm more than willing to work with him and give him access to my box
to do so.

        Do you have some utilities that might help me track down this problem?
Please let me know.

He has the last word, but (a) 1.3 is a development kernel, (b)
configuration can take the patches completely out if you don't use
quota, and (c) looking at some of the stuff which has made it into
1.3, I can't see stability as an issue.

I wouldn't use a 1.3 kernel on a production system on a bet,
although if some new feature comes along which needs a new kernel I
might have to. This is not at all like the 1.0 vs. 1.1 situation,
where the 1.0 kernel was stable but sadly limited. While there is
some new stuff in the 1.3 kernel, the 1.2 is able to handle serious
commercial production.

I agree, but for some reason, Linus doesn't like the quota patches. Do
you know the reason (Linus prejudice? What?)

Carlos Antunes.

Last time he gave us some comments about certain code. We changed it
accordingly to his whishes. never heard of it since ...
(and we really try ;-)
