[SOLVED] Migration error while upgrading packages to version 2.2

[gandalfmagic]

I'm sorry, but I've bad news. Last version of the script doesn't work for me.

I've extracted the list of active process at the moment of the error:

Code: [Select]

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
ebox      4304  0.0  0.2  53772  2468 ?        S    23:38   0:00 imap
ebox      4306  0.0  0.2  54188  2808 ?        S    23:38   0:00 imap
ebox      4308  0.0  0.2  53424  2256 ?        S    23:38   0:00 imap
ebox      4311  0.0  0.2  53888  2516 ?        S    23:38   0:00 imap
ebox      4313  0.0  0.1  53424  1992 ?        S    23:38   0:00 imap

When I try to manually kill them, the continue to pop-up.

Also, If I successfully kill ALL the processes and continue the script, I obtain the error in LDAP master sync:

Code: [Select]

Copying old ebox dirs to zentyal...
Importing old configuration...
Upgrading objects to new schema...
Upgrading ldap attributes (quotas from mail and users)...
Cannot restore slave machine when master is down: xxx.xxx.xxx.xxx run-parts: ./post-upgrade/004_upgrade_ldap exited with return code 255
Adding quota objectclasses...
Creating new core tables...
Importing old quota config
Migrating fetchmail accounts
No fetchamil accounts to migrate
Resetting data_version for all modules...

But the master is UP and running.

And after the migration, if I go in users or groups list from web interface on the server I get this message:

Code: [Select]

Zentyal is configured as slave and there are no users at the moment. You may want to add some in the master.

Finally, I've managed to solve 004_upgrade_ldap error:

This method worked for me, I hope it can help other people.
