Quota support

Quota support

[Michal Humpula]

Hi, 

I was interesting if there is some plan for linux quota support (I've searched 
the list and the code and found nothing). If it is, is there some experimental 
code or at least some place with ideas how it should be implemented?

Regards

Michal Humpula

Hi Michal,

Kristal Pollack did a paper on distributed quotas that represents one 
possible approach for enforcement in the case where clients are untrusted:

	http://ceph.newdream.net/publications/quota-voucher-paper.pdf

There is also the recursive accounting in the the MDS that in theory could 
facilitate subtree quotas.  It already implements the accounting half of 
the problem, but the implementation of enforcement would be tricky.  See

quota support

Hello,

as fas as I can see UBIFS doesn't support quota yet, is anyone working
on UBIFS quota support?

Dongsheng Yang posted a quota patch series some time ago, is this the
newest series https://github.com/yangdongsheng/linux/tree/ubifs_quota_v3 ?

regards,
Marc

Do you have any work in progress code?

AFAIK I was not really happy with the series because it did not
support project quotas
and had some issues with being power-cut tolerant.
VFS folks also had concerns since the quota subsystem assumes a block
device but UBIFS
works on top of a character device. This needs to be addressed is a
sane way too.

Quota Support

[Stephen]

Sorry about emailing the list about this but after doing some googling i
can't seem to find the answer.

Im just wondering if subvolumes or snap shot can have quotas imposed on
them.

The wiki says that:

"Subvolumes can be given a quota of blocks, and once this quota is
reached no new writes are allowed."

Although many posts to this mailing list and on other mailing list seem
to indicate that quotas are not implemented, im just wondering if
someone can clean this up.

Thanks Steve

Subvolume quotas are one of the many features that haven't yet been
implemented. See

data logging and quota updated for 2.4.23

[Chris Mason]

Hello everyone,

ftp.suse.com/pub/people/mason/patches/data-logging/2.4.23

Will have a new version of the data logging and quota code as soon as
the suse mirror system copies it over.

There are two changes here, first is 01-reiserfs-free-blocks, which
fixes a problem where reiserfs can falsely report the disk is full.

This required rediffing reiserfs-sync-fs and the data logging patch.

reiserfs-jh-3 has been removed while I work out a bug in it.  It
probably won't reappear in 2.4 form, since I'm trying to spend all my
time on 2.6 these days.  Aside from critical bug fixes (which I don't
expect ;) and minor merges with later 2.4 code, this should be the last
data logging/quota drop for 2.4

Hello,

'official' Namesys quota-patches are only available up to 2.4.20 and actually 
I thought that a new quota layer has been integrated in 2.4.21 and that quota 
for reiserfs is naturally supported since that version. 
However when I briefly looked through the quota-patch, it seems it adds basic 
quota stuff to the reiserfs-code.

Please, can someone here enlight me about current quota+reiserfs status?


Thanks,
	Bernd

PS: We are currently not using quota on reiserfs, but will need to use it 
within the next 6 weeks.

Hello,

Below you will find patches for kernels 2.4.20-23
ftp://ftp.suse.com/pub/people/mason/patches/data-logging/

I have already sent a post about kernel not compilig with quota patches 
applied if you dont' have modules enabled...

Hello Bostjan,

yeah I know about those patches, but actually I want to know about general 
quota support status:

1.)  So is there vanilla-kernel quota support for reiserfs since 2.4.21? 

2.1.)If not, why are there no quota patches on ftp.namesys.com for 
2.4.{21-23}? 

2.2) If there is quota support for these versions, what does the patch from 
Chris improve?

Thanks,
	Bernd

Re: quota support

[Bostjan Skufca (at) domenca.si]

Hello Bernd,

i've been asking the same questions and got myself an answer: RTFF (the last F 
stands for FAQ on namesys' webpage)

FAQ should answer your 1 and 2.2 questions. As for the 2.1 i think everyone at 
Namesys is concerned about Reiser4 and Linux 2.6.0 - thus patches for 2.4.xx 
are no longer amongst their top priorities. They do not bother hosting it on 
their ftp because are hosted on suse's and FAQ clearly directs it's readers 
to correct ftp site. 
Besides all that we should thank Chris for his patience and good will which, I 
believe, brings us THE patches.

Regards,
Bostjan

D'oh, stupid me, last time I checked the FAQ was several month ago. So I only 
searched in the download-section and only found references for 2.4.20.

Yeah probably you are right, I only thought since a new quota format was 
introduced in 2.4.21 and since I didn't find any quota-patches in the 
download section, quota support for reiserfs is already available since that 
kernel version.

Yes of course, Chris, many thanks for providing the patches.


Thanks a lot,

Chris and Vladimir, what is the status of quotas in the official kernel?

  Generic VFS support needed for ReiserFS is all there since 2.4.21.
Modification needed in ReiserFS code are only in Chris's patches AFAIK.
