Fulldirhash-metapartition bug?

[Tornoci Laszlo]

Hi,

I am in the process of migrating my users to a nice new hardware setup. 
I decided to change to fulldirhash and to migrate metadata to a separate 
partition. First I used "rehash" then "migrate-metadata". Aside from one 
glitch (rehash choked on the quota data of a root level mailbox called 
"net") everything went fine.

The problem is the following: I have 2 users with long usernames: 
csorcsabne and spatandras. Running squatter on these mailboxes dies with:

Oct 24 14:56:27 net-imap imaplocal[12992]: IOERROR: opening 
/var/lib/imap/meta/I/user/csorcsabne/cyrus.header: No such file or directory
Oct 24 14:56:58 net-imap imaplocal[12992]: IOERROR: opening 
/var/lib/imap/meta/F/user/spatandras/cyrus.header: No such file or directory

Which is not surprising, because the real hash of these users are S and 
V respectively, and NOT I and F as squatter tries to access the header 
files. I get exactly the same errors if I try to set ACLs on these 
mailboxes in cyradm. Listing mailboxes, listing ACLs is fine.

I am not familiar with the cyrus source, but this definitely looks like 
a bug. I created user.abcdefghij to see if all mailboxes with a 10 
character username have a problem, but this one worked fine.

This is Simon Matters' cyrus-imapd-2.3.9-3 on a 64bit Intel machine with 
RHEL 5.


By the way, I remember people having problems with index files after 
migrating to 64bit machines. Is this still an issue?
