Re: xfer problems between 2.3.15 and 2.4.17
this fix, detailed below, has indeed solved our problem with folder creation on our new 2.4.17 frontends. many thanks On Tue, 10 Jun 2014, Andrew Morgan wrote: > On Tue, 10 Jun 2014, gavin.g...@ed.ac.uk wrote: > >> Hi Wes, >> >> It looks like the whole mupdate thing is working perfectly well. >> If I create a folder while connected to my 2.4.17 frontend then the logs >> show the backend issuing the cmd_set and then a bunch of cmd_find going >> out including to the frontend in question.

See this message from the archives: http://asg.andrew.cmu.edu/archive/message.php?mailbox=archive.info-cyrus&searchterm=Murder%20mailbox%20create%20race%20condition&msg=54193 I ran into this same problem, which was introduced by changes in v2.4.13. The imapd.conf manpage says: proxyservers: A list of users and groups that are allowed to proxy for other users, separated by spaces. Any user listed in this will be allowed to login for any other user: use with caution. In a standard murder this option should ONLY be set on backends. DO NOT SET on frontends or things won't work properly. Let us know if removing proxyservers from your frontends fixes the problem!

Re: xfer problems between 2.3.15 and 2.4.17
Hi Wes, It looks like the whole mupdate thing is working perfectly well. If I create a folder while connected to my 2.4.17 frontend then the logs show the backend issuing the cmd_set and then a bunch of cmd_find going out including to the frontend in question. Furthermore the new folder really is there in the mailboxes.db on the frontend. So in a way that's reassuring, but then why is the frontend telling email clients that the folder doesn't exist when a request to subscribe to it comes in? We aren't seeing any kick_mupdate getting logged. The only thing is we see two cmd_sets is that normal? : Jun 10 11:07:29 mupd1 mupdate[31917]: cmd_set(fd:5, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_set(fd:5, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:29, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:29, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:24, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:24, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:25, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:25, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:10, user.gaving.gavarella) Jun 10 11:07:30 mupd1 mupdate[31917]: cmd_find(fd:10, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:11, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:11, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:36, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:36, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:26, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:38, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:38, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:14, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:22, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:22, user.gaving.gavarella) Jun 10 11:07:31 mupd1 mupdate[31917]: cmd_find(fd:26, user.gaving.gavarella) ... fd 38, and 26 is the 2.4.17 frontend in question.

This is tickling my memory, but I can't recall exactly what it was. I remember running into a problem like this as well.

I used the following when I upgraded from 2.3 to 2.4: suppress_capabilities: ESEARCH LIST-EXTENDED QRESYNC WITHIN XLIST ENABLE SORT=DISPLAY There was a thread I started back in October 2011 with the subject "2.3 to 2.4 Murder upgrade" where I ran through the upgrade and the workarounds I had to make.

It's exactly what we did to migrate our murder environment from 2.3.x to 2.4.x. I think I posted to the info-cyrus list about how we upgraded, but maybe I didn't. I got all the 2.4 backend servers built and ready to go, then I upgraded all the frontends to 2.4, then I used XFER to move all the mail from 2.3 to 2.4 servers. I don't recall exactly when I upgraded our mupdate server, but I don't think it matters. I don't believe anything changed in mupdate protocol or in the mailbox.db format between 2.3 and 2.4. Have you tried grabbing telemetry on the 2.4 server when the subscription fails? Is there anything being logged? Thanks!

xfer problems between 2.3.15 and 2.4.17
As you may be aware we are attempting this and have run into various problems. Currently we have a mixed murder of 2.3.15 backends and 2.4.17 backends. We are now fairly confident that we can xfer accounts succesfully between these backends. The problems we had appear to have been with a very small number of accounts on our older backends that had corrupt cyrus.index files. However we are now having trouble configuring frontends that will work with this mixed murder environment while we xfer our users accross. If we use our existing 2.3.15 frontends then users have who have been migrated lose the ability to see other accounts in the "Other Users" name space. On the other hand if we introduce 2.4.17 frontends then we see strange behaviour around folder creation. Clients can create the folders but autosubscription fails with the client being told the new folder doesn't exist. If one waits a minute or two one can manually subscribe to the folder. So far we have not upgraded the mupdate master. Is this a mistake? In terms of the frontend config we have added suppress_capabilities: ESEARCH QRESYNC WITHIN XLIST LIST-EXTENDED to the 2.4.17 frontends, otherwise the config is identical to our 2.3.15 frontends. Is there any other config changes we should be aware of? any ideas greatly appreciated...

Re: xfer problems between 2.3.15 and 2.4.17
So I'm going to attach the cyrus metadata files for a folder that behaved the way I am describing having been xfer'd between 2.3.15 and 2.4.17. these are the files from the source server ie the 2.3.15 backend. If anyone with far deeper knowledge of cyrus than we do, could have a look to see if they can identify a problem and possibly find a solution then we would be very grateful.

Re: xfer problems between 2.3.15 and 2.4.17
Thanks Ken, We have tried the -G and -R options to no avail. I've begun to experiment with your seen database idea. It would be nice to discover the reason for the corruption. We still don't even know whether the problem was there before the xfer or if it's a result of the xfer process. Obviously there are some major changes from cyrus 2.3.15 to 2.4.17, but then mostly folders are migrated and 'upgraded' correctly. cheers, Gavin Gray On Thu, 15 May 2014, Ken Murchison wrote: > Hi Gavin, > > Have you tried running reconstruct with the -G and/or -R options to see if > they fix the corruption without having to remove cyrus.index? > > Another option is to place a copy of the user's .seen file from the 2.3 > machine on the 2.4 machine prior to removing cyrus.index and reconstructing. > I *think* the server will then upgrade the seen state from .seen to > cyrus.index. > > > > On 05/15/2014 11:53 AM, gavin.g...@ed.ac.uk wrote: >> Any help with this would be much appreciated. >> >> We keep coming across folders that once they have been migrated seem to >> have corrupt cyrus.index files.

Re: xfer problems between 2.3.15 and 2.4.17
Hi Gavin, Have you tried running reconstruct with the -G and/or -R options to see if they fix the corruption without having to remove cyrus.index? Another option is to place a copy of the user's .seen file from the 2.3 machine on the 2.4 machine prior to removing cyrus.index and reconstructing. I *think* the server will then upgrade the seen state from .seen to cyrus.index.
