Hi,

With same config as Kerl and Your patch I'm still getting thiese errors

May 16 12:11:36 thebe2 dovecot: imap(lazy): Debug: Namespace backup_h1: type=private, prefix=backup-h1., sep=, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/snapshot/h1/vmail/la/lazy/Maildir:INDEX=MEMORY May 16 12:11:36 thebe2 dovecot: imap(lazy): Debug: maildir++: root=/snapshot/h1/vmail/la/lazy/Maildir, index=, control=, inbox=, alt= May 16 12:11:36 thebe2 dovecot: imap(lazy): Error: open(/snapshot/h1/vmail/la/lazy/Maildir/.SPAM/dovecot-uidlist.lock) failed: Read-only file system May 16 12:11:36 thebe2 dovecot: imap(lazy): Error: file_dotlock_create(/snapshot/h1/vmail/la/lazy/Maildir/.SPAM/dovecot-uidlist) failed: Read-only file system May 16 12:11:36 thebe2 dovecot: imap(lazy): Error: open(/snapshot/h1/vmail/la/lazy/Maildir/.SPAM/dovecot-uidlist.lock) failed: Read-only file system May 16 12:11:36 thebe2 dovecot: imap(lazy): Error: file_dotlock_create(/snapshot/h1/vmail/la/lazy/Maildir/.SPAM/dovecot-uidlist) failed: Read-only file system May 16 12:11:36 thebe2 dovecot: imap(lazy): Error: open(/snapshot/h1/vmail/la/lazy/Maildir/.SPAM/dovecot-uidlist.lock) failed: Read-only file system May 16 12:11:36 thebe2 dovecot: imap(lazy): Error: file_dotlock_create(/snapshot/h1/vmail/la/lazy/Maildir/.SPAM/dovecot-uidlist) failed: Read-only file system May 16 12:11:36 thebe2 dovecot: imap(lazy): Disconnected: Internal error occurred. Refer to server log for more information. [2012-05-16 12:11:36] in=259 out= 100540

maybe it will be easier to move all dovecot metadata to separate (non snapshot) location ?

I have two problems :

• In my log, dovecot complain about the fact that my snapshot filsystem is read only Error: open(/da1/test2@toto.com/Maildir/.Trash/dovecot-uidlist) failed: Read-only file system

See if http://hg.dovecot.org/dovecot-2.1/rev/7f238016db81 helps. If you're not saving mails via dovecot-lda it might still complain if there are new files.

Also if it complains about indexes add :INDEX=MEMORY to location.

Alternative to the patch is to add :CONTROL=~/Maildir/snapshot-control/% u or something to location, but that could get problematic also.

...

The second problem is that through my thunderbird I can't see the Inbox saved in the snapshot (whereas I see Sent and Trash folders)

It should be accessible as "INBOX.backup.da", although some older Dovecot versions don't handle that properly.

Does the attached patch help?

It could also be a bit problematic. At least message keywords (=custom flags) wouldn't work because the dovecot-keywords file exists only in the snapshot dir.

Moving metadata helped, but now archived inbox is unsubscribed. Is there a way to make all folders in an namespace subscribed by default ?

Nope. I could try to get the snapshots fixed at some point when I have more time, but I'm not going to add a feature to subscribe everything by default. People might try to start using it.

If I enable per snapshot subscriptions i see all folders except INBOX, i have tried to subscribe it using mailbox_list_subscription_fill_one() or using imap as bellow without success

http://dovecot.org/list/dovecot/2007-October/025965.html suggest that it isn't possible
