Good morning,
I have been checking how could we manage for automating master -> slave and
slave->master transition. I though one possibility could be having both servers
configured in master mode with each being replicating to the other one. I know
this was some time ago unsupported and have tried if it worked now in a testing
env but it seems it fails too… Could any Cyrus guru confirm that really this
does not work (just for avoiding driving myself crazy trying to find the config
issue)?.
By the way, I’m in progress too of automating mailbox movements… from
partition, from server… I had a question about renaming mailboxes for moving
from cyrus partition… as a safety measure, prior to launch a renm operation
(renm user/a...@bb.es <mailto:user/a...@bb.es> user/a...@bb.es
<mailto:user/a...@bb.es> different-partition) we block any kind of access to
that mailbox (even mail delivering)… and I was wondering if that is really
necessary nowadays…. or does Cyrus hold that locks by it’s own?. I mean does
Cyrus take care by it’s own, of avoiding mailbox corruption due to a renm
mailbox to a different partition?.
Just one more question… when we move a mailbox from a partition (a renm to
different partition) to another one… we usually do :
- stop replication between master/slave (as a safety measure for having a very
last “fall back” if the renm goes wrong). You know, promoting the slave to
master would have the mailbox of the failed renaming operation properly...
- renm in the master
- after successful rename, delete from the slave the mailboxes
- sync each of the master mailboxes to the slave… this way among other things,
the removed mailboxes in the slave (the dm is done in the slave for causing
mailboxes to be resynced again from the master to the slave to it’s new
location in the slave)
- start replication again…
Are all this steps really necessary?. What do you think about it?.
Best regards,
