zfs discuss - Nov 2009 - rquota didnot show userquota (Solaris 10)

Hi,

we have a new fileserver running on X4275 hardware with Solaris 10U8.

On this fileserver we created one test dir with quota and mounted these
on another Solaris 10 system. Here the quota command didnot show the 
used quota. Does this feature only work with OpenSolaris or is it 
intended to work on Solaris 10?

Here what we did on the server:

# zfs create -o mountpoint=/export/home2 zpool1/home
# zfs set sharenfs=rw=sparcs zpool1/home
# zfs set userquota at wib=1M zpool1/home

# mkdir /export/home2/wib
# cp <some stuff> /export/home2/wib
# chown -Rh wib:sysadmin /export/home2/wib

# zfs userspace zpool1/home
TYPE        NAME    USED  QUOTA  
POSIX User  root      3K   none  
POSIX User  wib     154K     1M  

# quota -v wib
Disk quotas for wib (uid 90):
Filesystem     usage  quota  limit    timeleft  files  quota  limit    timeleft
/export/home2
                 154   1024   1024           -      -      -      -           -

and the client:

# mount <server>:/export/home2/wib /mnt

% cd /mnt
% du -sk .
154     .

% quota -v wib
Disk quotas for wib (uid 90):
Filesystem     usage  quota  limit    timeleft  files  quota  limit    timeleft


A simple snoop on the network shows us:

  client -> server   PORTMAP C GETPORT prog=100011 (RQUOTA) vers=1 proto=UDP
  server -> client   PORTMAP R GETPORT port=32865
  client -> server   RQUOTA C GETQUOTA Uid=90 Path=/export/home2/wib
  server -> client   RQUOTA R GETQUOTA No quota

Why ''no quota''?

Both systems are nearly fully patched.


Any help is appreciated. Thanks in advance.

Willi

ZFS userspace quota doesn''t support rquotad reporting. (.. yet?)

This thread seems to say it should work:

  http://mail.opensolaris.org/pipermail/zfs-discuss/2009-May/028291.html

And even the zfsadmin guide tells us:

  You can use the legacy quota command to review user quotas in an NFS
  environment, for example, where a ZFS file system is mounted.


So still the question: why does it not work in my setup?

Willi

Hopefully this will confirm to you that it should work:

x4500-10:~# zfs get userquota at 57564 zpool1/sd02_www
NAME             PROPERTY         VALUE            SOURCE
zpool1/sd02_www  userquota at 57564  29.5G            local



prov01# df -h |grep sd02
x4500-10.unix:/export/sd02/www    16T   839G    15T     6%    /export/sd02/www

remote/read/write/setuid/devices/vers=4/hard/intr/quota/xattr/dev=4700038


# quota -v 57564
Disk quotas for (no account) (uid 57564):
Filesystem     usage  quota  limit    timeleft  files  quota  limit    timeleft
/export/sd02/www
                   15 30932992 30932992                  0      0      0



I would suggest the usual things to check:

online         Aug_20   svc:/network/nfs/rquota:default

If you are using NFSv4, check /var/run/nfs4_domain match, we mount the volumes 
with "-o rq" (due to legacy reasons, it was UFS at one time) but I
don''t know if
that is still required.

I tried this too:

client# mount -F nfs -o quota server:/export/home2/wib /mnt
client# mount | egrep ^/mnt
/mnt on server:/export/home2/wib
remote/read/write/setuid/devices/quota/xattr/dev=598003f on Fri Nov 27 06:41:56
2009

and ''quota -v'' still shows nothing :-((

I think I will oben a service call.


Thanks for your help.

Willi

This is
CR 6907830 rquotad(1M) doesn''t return quotas for ZFS if NFS client 
mountpoint differs from entry in /etc/mnttab

Fix is in progress.
Thanks,
Lin
