Hello everyone!
I would like to report a bug here. We are using dovecot's sdbox with alternate storage here. From time to time my SSD partition gets full and I always find users with lots of e-mails stuck there, and altmove just won't move them. It moves most of the e-mails correctly, but a few was getting stuck everyday.
So, I think I have found the problem! When a user moves the message from one mailbox to another, the move will keep all the flags! Including MAIL_INDEX_MAIL_FLAG_BACKEND 0x40. So, altmove think this message was already moved and doesn't do anything.
I did a doveadm dump on the destination mailbox's index and what I see is a lot of this:
RECORD: seq=104, uid=104, flags=0x48 (Seen)
- ext 0 keywords : (0000)
- ext 1 modseq : 12 (0c00000000000000)
- ext 3 cache : 14004 (b4360000)
- cache offset=14004 size=76, prev_offset = 0
- mime.parts: (48000000b404000000000000cc04000000000000e542000000000000fd4300000000000018010000) (pos=0 hdr.p=1204 hdr.v=1228 body.p=17125 body.v=17405 flags=48)
- size.physical: 18329 (9947000000000000)
- date.received: 1418235366 (e68d8854)
Although the 0x40 flag is set, the file still lives on the main/ssd storage area.
My config: http://pastebin.com/8Wk4bfRK Dovecot version: 2.2.5-0~auto+22 Host is Xeon E3 64bit, running Debian 7. Filesystem is plain local ext4 on both storage areas
I know my version is outdated but I didn't find anything related to this there.
Just one last question: how can I remove that flag from the message? I have taken a look at doveadm-flags(1) but it doesn't seem to allow anything on that flag.
Thank you very much!
Best, Daniel Colchete
