1) The AIX quotactl subroutine is defined here(put it in the search box)
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp
Partial cut and paste of it:
*#include jfs/quota.h*
*int quotactl (*/Path/*,*/ Cmd/*,*/ ID/*,*/ Addr/*)*
*int* /Cmd/

** /Path/
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/topic/com.ibm.aix.basetechref/doc/basetrf2/quotactl.htm#xpk2250bob*;*
Description
The *quotactl* subroutine enables, disables, and manipulates disk
quotas for file systems on which quotas have been enabled.
On AIX, disk quotas are supported by the legacy Journaled File System
(JFS) and the enhanced Journaled File System (JFS2).
The /Cmd/ parameter is constructed through use of the
*QCMD(*/Qcmd/*,*/ type/*)* macro contained within the
*sys/fs/quota_common.h* file. The /Qcmd/ parameter specifies the quota
control command. The /type/ parameter specifies either user
(*USRQUOTA*) or group (*GRPQUOTA*) quota type.
The valid values for the /Cmd/ parameter in all supported file system
types sare:
*Q_QUOTAON*
Enables disk quotas for the file system specified by the /Path/
parameter. The /Addr/ parameter specifies a file from which to
take the quotas. The quota file must exist; it is normally created
with the *quotacheck*
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/topic/com.ibm.aix.cmds/doc/aixcmds4/quotacheck.htm#a84c12e
command. The /ID/ parameter is unused. Root user authority is
required to enable quotas. By specifying the new quota file path
in the /Addr/ parameter, the *quotactl* command can also be used
to change the quota file that is being used without first
disabling disk quotas.
*Q_QUOTAOFF*
Disables disk quotas for the file system specified by the /Path/
parameter. The /Addr/ and /ID/ arguments are unused. Root user
authority is required to disable quotas.
Additional JFS specific values for the /Cmd/ parameter are as follows:
*Q_GETQUOTA*
Gets disk quota limits and current usage for a user or group
specified by the /ID/ parameter. The /Addr/ parameter points to a
*dqblk* buffer to hold the returned information. The *dqblk*
structure is defined in the *jfs/quota.h* file. Root user
authority is required if the /ID/ value is not the current ID of
the caller.
Did the trace hold any more information? Note that I didn't attach it
the first time I sent it to you, the second time I did. I also resent
the note with the trace attached to mailing list, but the mailman
software said it was too big, so I canceled the second post.
2) No, nothing is remote here:
1) dovecot is running here on mercury
2) mercury is where all the inboxes and home/folder dirs physically reside
3) These /are/ exported to other machines by mercury.
4) The quotaing is running on here mercury itself as part of O/S and
FSes; it is enabled during boot
5) rquotad runs to provide quota info to the remote machines where the
inboxes and home/folder dirs are NFS client imported and mounted

quotactl(Q_GETQUOTA, /) failed: Invalid argument
So apparently this quotactl() call is wrong with AIX:
if (quotactl(root-mount-mount_path, QCMD(Q_GETQUOTA, USRQUOTA),
root-uid, (void *)dqblk) 0) {
I don't know why though. You could try changing root-mount-mount_path
to some actual mbox file path to see if it returns errors then.
Except weren't your mailboxes NFS mounted? quotactl() doesn't work for
NFS mounts at all. For NFS you could try this instead

[Dovecot] AIX mail quota plugin problems
From reading the wiki for a filesystem quota, I took my shot at
1) building my binaries using the mods in AIXPluginsSupport
2) changing dovecot.conf and
3) putting the plugins in the library
But I'm getting this error message when I invoke dovecot:
Plugin imap_quota not found from directory /usr/local/lib/dovecot
Error: imap dump-capability process returned 89
It would seem that
a) I have the syntax or the parameters wrong
b) I didn't get the changes to the AIX build environment right
I've attached the dovecot -n output.
Here are the details of what I did.
1) dovecot.conf
=== within the imap config section ===
# Support for dynamically loadable plugins. mail_plugins is a space
separated
# list of plugins to load.
#mail_plugins =
#mail_plugin_dir = /usr/lib/dovecot/imap
# SD 5/24/07 tryout FS quota plugin
mail_plugins = quota imap_quota
mail_plugin_dir = /usr/local/lib/dovecot/imap
plugin {
# Here you can give some extra environment variables to mail processes.
# This is mostly meant for passing parameters to plugins. %variable
# expansion is done for all values.
# Quota plugin. Multiple backends are supported:
# dirsize: Find and sum all the files found from mail directory.
#Extremely SLOW with Maildir. It'll eat your CPU and disk
I/O.
# dict: Keep quota stored in dictionary (eg. SQL)
# maildir: Maildir++ quota
# fs: Read-only support for filesystem quota
#quota = maildir
# SD 5/24/07 Try FS quota support
quota = fs
I've tried it as both
mail_plugin_dir = /usr/local/lib/dovecot/imap
and
mail_plugin_dir = /usr/local/lib/dovecot
2) Both ways I see this error message:
4229 [EMAIL PROTECTED]:/usr/local/etc ## dovecot
