2.4, 2.4-ac and quotas

2.4, 2.4-ac and quotas

[Matt Bernstein]

I'm desperately looking for some recent documentation on quotas.

We've recently upgraded our two Debian potato fileservers to 2.4 and
2.4-ac (currently they're both running 2.4-ac so I can't check 2.4 atm)
and quotas have stopped working.

The quota package is 3.00pre01-7.bunk, and quotaon calls quotactl which
returns -1 ENOENT (No such file or directory), as it's looking for
aquota.user, evidently a "version 2 quota" (according to the edquota
manpage), and not falling back to the quota.user files which do exist.

So now we're essentially running without quota support :-(

On another computer (Debian woody) I've made an ext3 partition, touched
aquota.user and quotactl now returns -1 EINVAL (Invalid argument).

Please can anyone help? Should I switch to XFS and go back to a
2.4.5-based kernel?

The -ac kernels use the updated quota tools - they are needed to support
32bit uid quota

OK.. so I download and build quota-3.01-pre9 on my woody box and I still
get EINVAL (2.4.9-ac10 + ext3 0.9.9 + ext3 speedup + ext3 experimental VM
patch + jfs 1.0.4). Can you tell me where the updated tools are please?

I got them from the quota folks. They are also packaged by most (non debian)
vendors. If you cant find the right tar ball I can pull it out from one
and send it to you

That is the package I'm using with 2.4.9-ac10.  Did you convertquota?

  Before you can use new quota you have to convert old quotafiles to new
ones. You can do this by convertquota(8) utility which is in the package.
Or you can just run 'quotacheck -F vfsv0 -c <mountpoint>' to create completely
new quota files with new quota format.
  3.01-pre9 which Alan pointed you to is the latest release of quota tools
(I have already some bugfixes but they are of minor nature).

Thanks--over the weekend I appear to have that bit working. I still can't
add quotas to my shiny new ext3 partition though :(

$ touch /export01/aquota.user
$ umount /export01
$ mount /export01 -o usrquota
$ quotaon /export01
quotaon: using /export01/aquota.user on /dev/sda3: Invalid argument

The strace shows:
quotactl(0x10000, 0x8053fe8, 0, 0x8053fc8) = -1 EINVAL (Invalid argument)

Is there a recent HOWTO on this (maybe I've got it wrong)?

Cheers,

Matt

  And are you sure that /export01/aquota.user is correct quotafile (ie.
created by quotacheck or convertquota)? This is message you usually get
when quotafile has incorrect header... (or also when bogus arguments
are specified but it's probably not your case).

Bingo.. I naively read http://www.linuxdoc.org/HOWTO/mini/Quota.html
and applied it to vfsv0. Could this be updated to reflect the new quotas
please? I'd like to read of the differences--is, for example, the new
quotacheck faster? Or does it all depend on the speed of the underlying
filesystem ond not much else?

Thanks,

Matt

  Ok. I'll try to update the howto and send it to maintainer.

  The main difference is that new quota format supports 32-uids. There are
other minor changes - like root is no longer special user and such.
  quotacheck speed relies completely on filesystem speed - quotacheck
has to scan all the filesystem. If you use e2fslib support on ext2 than
it should be reasonably fast but I agree that otherwise it's pain.
