Re: [vchkpw] qmail queue directory...
I think I will try to use the symlik and then run qmail queue-fix program.
I had nice results a little bit ago moving a whole system to another
drive. I tarred everything and opened to the filesystems in new disk.
The only thing which didnt work was again qmail trigger file (I assumed
but might be something else) I ran the qmail-queue-fix program and
everything is working.
Now I think that trigger file was not the problem but the inode numbers
which are changed when I tar the directory and open back was.
Also now I know that I can just move the queue directory symlink it then
run qmail queue-fix program and everything will work.
Thanks

Hi Evren,
Please don't send any reply to me privately unless explicitely
requested. I do read the list (else I wouldn't have been able to answer
your question) and I don't need two or more copies of one mail.
Thank you.

What about an extra partition for '/var/qmail/queue' that's simply
mounted there? No need for symlinking, lots of space, not affected by a
possible overflow in '/var/log', etc , etc ...

Stop the SMTPD for no new mails coming in. Make your best attempt to
stop processes that might inject mails locally.
Send 'qmail-send' process an 'ALRM' signal. Wait.
You'll /NOT/ loose any external mail that can't be delivered due to the
fact the SMTP is down, /IF/ the foreing MTAs are configured correctly.
They should keep the message "in queue" for several days until your MTA
is up again (if you don't even have a backup MX for your domain).

Maybe because 'qmail-send' still ran when you did something on this
file? It's 'fifo', a 'name pipe' and qmail-send keeps a handle opened on
this file. Stop qmail-send before moving anything and if you've any
trouble moving 'lock/trigger' "as is" use 'mkfifo' to recreate it at
it's new location.

'make setup' in qmail source tree will generate the queue structure.
But you can easliy
pushd /var/qmail/queue
find . -type d | \
(cd /path/to/new/queue/dir;
while read $DIRECTORY; do mkdir "$DIRECTORY" && \
chown --reference=/var/qmail/queue/$DIRECTORY && \
chmod --reference=/var/qmail/queue/$DIRETORY ;
done)
It's then two files to copy: './lock/{sendmutex,tcpto}' and the fifo
'./lock/trigger' that has to be created and you're done with creating a
new, clean qmail-queue-structure.

Re: [vchkpw] qmail queue directory...
I want to change it because current queue directory is in /var/qmail/queue and I figured out that the 256mbyte in /var filesystem might be insufficient if there comes too much emails with attachments from my customers at the same time. Plus the undeliverable ones etc. I thought I might use this qmail queue fix tool from qmail web page. I simply dont know how to empty the queue ? Previously I had bad experience with lock/trigger file in queue directory. I also wonder how to regenerate it with correct options in the new filesystem. :) There was supposed to be a make command for that but :) Evren On Fri, 22 Aug 2003, Peter Palmreuther wrote: > Hi Evren, > > On Fri, 22 Aug 2003 11:18:29 +0300 (WET) Evren Yurtesen wrote: > > > I know this is not the right list but do you know how can I change the > > qmail's queue directory nicely? :) Is a little symlink to another location > > would do? or would sacrifice too much of performance? > > It should work and not impact on performance /too/ much, but why do you > want to change the location? > > But be aware the queue is empty before you switch over, files names used > in queue directory are 'Inode-bound', simply moving the queue files will > break them. > -- > Ciao, > Pit > >

It should work and not impact on performance /too/ much, but why do you want to change the location? But be aware the queue is empty before you switch over, files names used in queue directory are 'Inode-bound', simply moving the queue files will break them. -- Ciao, Pit
