Still on the problem with dovecot 2.2.27 ....

I use the single instance storage, and mdbox format. I use 2 zfs file systems, one for mailboxes, the other for attachements. I use znapzend to generate many zfs snapshots for backup purpose (inode numbers are preserved but it is unusefull).

When I try to restore a deleted/purged mailbox with doveadm import I get the error of the first attachement missing in the SIS and the process stops.

Option 1: the python script is working but it's really too long.

* I restore all the SIS missing files since the snapshot date,

preserving hard link count;

* I restore the mailbox

* I purge all the mailbox to delete the large number of unnecessery

files restored

Option 2: looking in the list archive I see that doveadm dump can guive me the msg.ext-ref that was missing to my knowledge.

I try this use of doveadm dump:

doveadm dump /MySnapShot/vmail/user/mdbox/storage/m.*

Is this correct to get all the information I need ?

I have to write a script to get msg.ext-ref for a particular msf.guid, or a specific mailbox

Is there a way with doveadm dump to extract this type of information for a particular mailbox ?

Thanks for your support.
