Moving Alternate Storage to another disk.

[bOnK]

Hello,

Dovecot 2.3.4_3 on FreeBSD 11.2.

I am using mdbox Alternate Storage since about two years without any 
problems.
However, the disk containing this storage is almost full and I have to 
move this data to another disk, probably zpool.


Would it be okay to do the following?
1) Shut down dovecot (and mail server) so no new mail comes in.
2) Copy/move all files in ALT location to new disk, using shell commands 
like cp/mv/cpdup.

3) Change the path to ALT in dovecot-conf mail_location.
4) Change the 'dbox-alt-root' soft-links in each users main (INBOX) 
directory to point to this new location.

5) Start up dovecot and mail server.

Am I missing something or maybe there is a better way?

Thanks, and have a nice new year.

Hi,

if you have the new disk installed on the same server you can try:

- mount new disk for example in /mnt/temp
- rsync -vaWH all files + directories from the old to the new disk
- stop dovecot so no changes will happen on disks
- make a final rsync again -> should not take many time
- umout the old disk
- mount new disk to the original "alt-storage" path, so you don't have 
to change each soft-link in each users directory.

- start dovecot

Not tested, but in theory it should work.

Best

Any idea why?

mdbox Inconsistency in map index

[bOnK]

After a (power)crash two accounts have been corrupted.
I tried to rescue things by running force-resync multiple times, but 
that didn't work out.
Searching the archives, I found a recent suggestion (by Timo) to delete 
the index files, but I'm not sure which files to delete and what the 
consequences will be.
When I deleted ``storage/dovecot.map.index'' in an unimportant account 
of my own, things only grew worse and I decided to delete the account 
and start fresh...


Something I obviously don't want to do with the other account as it 
belongs to a client with about 2.5G mails (856 m.* files), which we 
don't want to lose.


I have observed the following behavior in the logs:

Besides the nuisance of getting kicked of every time a new mail arrives, 
user cannot delete mails (as in: move to Trash).


TL;DR: which files to delete and what will be the consequences?
