Hi, I was wondering... If one had mdbox ALT path set to a shared storage mount (say, on NFS) and one wanted to move a mailbox to a different host... I guess it in principle wouldn't be necessary to copy all the ALT storage through dsync, when the volume could just be mounted on the new host. Is there anyway for dsync to avoid moving Gigabytes of data for could just be "moved" by

So... I've done some testing. One method which seemed to work - at least for primitive cases - was to: * Mount the ALT storage on the destination. * Run "doveadm force-resync \*" on the destination. (putting all the mails in ALT storage into the dovecot.map.index) * Run dsync from source to destination. Of course... if there was some way to avoid step 2... /Peter

I was thinking about documentation for alternate storage. We have a few mentions at: http://wiki2.dovecot.org/MailboxFormat/dbox http://wiki2.dovecot.org/Tools/Doveadm http://wiki2.dovecot.org/Tools/Doveadm/Altmove But I was thinking it would be helpful if there could be a page about alternate storage. I could write the page, but I currently have so many unknowns that I think it would be
