Hi bill, Will try and find the rsync errors I saw when I was testing all of this. The part of the script you commented out controls the size of the logfile, but since 20Mb is rather large it takes time to run, so it can mange without it. Your script runs fine on my system. However I suspect the problem lies in the size variable. the ls listing in centos is probably different to fedora. Run the below command and see which field it is displaying. Is should be the size portion, but it may not be. Increment or decrese the 5 until you get the correct result, and edit your script accordingly. However you can manage without that if you want to manually rotate your logs. ls -l $LOG|cut -d ' ' -f 5 As for the rsync errors, the errors relating to MY.DOMAIN are normal if your mail is being deleted from the server as people check. It will be down to the script running after a file was there, and during the run was deleted. What happens if you run /unison/unison -force / -batch qmail and then run it again straight after it completes, are the errors identical or do they differ or go away? It may be that you need to reset the unison database. To do that on both servers do the following. cd /root/.unison. If you do ll you will see something similar to arb35cf206e53266f6ceb48d38f9f6c049. That is the database, if you delete or rename those on both servers and then run the command it will repopulate the data it is working with. Try that and let me know. P.S. If you do sort out the size variable on your system could you leave a comment on the wiki, or let me know the details so I can leave a note for other centos users. Also did you notice I took the backup server side script out of cron, as it isn't really necessary and should be run manually in the case of a switch over. However I would recommend, that you test your backup server on a regular basis to make sure it is working and you can logon. Run the qmail-replicateb script and then verify.
I normally activate the backup server, and change my account to point to it, and make sure I can authenticate. I also do /home/vpopmail/bin/vuserinfo randomn users and confirm their details. Hope that helps. Let me know what unison says after a clearout.

Thanks. Best regards, Bill On 11/27/06, Craig Smith <[EMAIL PROTECTED]> wrote: Hi Bill, It's no problem, I hope I can help get it sorted and that it works as well for you as it does for me. Does the error you get still reflect the same line now that you've recopied the script? the unison run seems to be running. I see 2 failures and I can't remember at this point what they indicate, but I have seen them before. If the script error is still on the same line, can you comment out the section you pasted and let me know what it says then. So add # in front of each line from 61 to 65. It is probably something that centos expects that fedora doesn't. I've not worked with centos before. Jake or Eric, do you guys know if Centos handles shell script slightly differently? Also bill could you attach the script from your server, so I can run your exact script on my server and see what happens?

Assuming that the unison application and the qmail.prf file is in place, it should run fine. Try running the unison command manually and let me know what happens. /unison/unison -force / -batch qmail Did you skip anything in the process or run into problems during it? It may be something that centos doesn't like that fedora doesn't care about, but I can't say as I've never used centos. Try recopying, the script and let me know what happens.

It may just be something that copied from the site. In terms of setup, on the backup server you don't need to create anything, just have QMT installed and working. The replication script will replicate all folders, users, control files and mysql data to populate the backup folder. The fact that you are getting an error in the script means there is something wrong on line 61. On my line 61 there is an open line with nothing. I will copy the one from the wiki and run it to see what I get. As for the file, it fails during transfer which is why it is blank. Let me see what happens if I copy and paste directly from the wiki. Also I've just made a minor change to the qmail-replicatec file by adding a lock file process, as mine went a bit nuts last night. Also I've removed the qmail-replicateb from cron as this only really needs to be run if you switch to the backup. Sorry for the slow reply been mad busy.

Both machines are running CentOS 4.2. I've just installed qt to my backup server, but no domains and users were setup. I am having problem in synchronizing them. When I run the qmail-replicatec, I got the following error: [EMAIL PROTECTED] unison]# ./qmail-replicatec ./qmail-replicatec: line 61: [: root: integer expression expected In the unisonlog.full, some error message such as the following are logged: Failed: The file /home/vpopmail/.spamassassin/auto-whitelist has been modified during synchronization: transfer aborted 2% 04:06 ETAFailed [home/vpopmail/.spamassassin]: The file /home/vpopmail/.spamassassin/auto-whitelist has been modified during synchronization: transfer aborted Failed: The file /home/vpopmail/domains/my.domain.com/alison.lam/Maildir/maildirsize has been modified during synchronization: transfer aborted 2% 04:06 ETAFailed [home/vpopmail/domains]: The file /home/vpopmail/domains/my.domain.com/userA/Maildir/maildirsize has been modified during synchronization: transfer aborted UNISON finished propagating changes at 17:04:14 on 23 Nov 2006 Saving synchronizer state Synchronization incomplete (1 item transferred, 0 skipped, 2 failures) failed: home/vpopmail/.spamassassin failed: home/vpopmail/domains Then I found that there's no file copied to /home/vpopmail/domains.
