Upgrade 4.5.3 -> 4.5.6 failed: ldap hangs

[sm3.142]

Hello,

I've attempted an upgrade of a Zimbra 4.5.3 to 4.5.6 on an Fedora Core 4 system. I started out well but doesn't seem to get past starting LDAP, i.e. the install process is hanging here (since about half an hour or so):

Restoring existing configuration file from /opt/zimbra/.saveconfig/config.save...done
Operations logged to /tmp/zmsetup.log.8971
Checking ldap status
Starting ldap

Checking the processes:

# ps -eaf | grep ldap

root     11282 32621  0 21:56 pts/0    00:00:00 grep ldap

So it looks to me like slapd is not detaching. Looking at what slapd is doing:

# strace -p 9349
Process 9349 attached - interrupt to quit
futex(0xb3a8fbf8, FUTEX_WAIT, 9351, NULL

which doesn't tell me a lot, not knowing anything about the internals of slapd, but it clearly is not doing much!

also found this thread: Upgrade: 4.5.5 -> 4.5.6 failed, LDAP/slapd issues, which may be related, but while it mentions that the issue was resolved, it doesn't say how!

Any help is wildly appreciated as I'm really not sure what to do next - stop the upgrade and try it again?

thanks

Ok, I resolved one question, namely how to proceed, by hitting Ctrl-C in the wrong window. It's proceeding with the update now, but not before saying:

...
Starting ldap
ERROR: service.FAILURE (system failure: getDirectContext) (cause: javax.naming.CommunicationException mail.elit-caffelatte.com:389)
Setting defaults...Done
Setting defaults from existing config...Upgrading from 4.5.3_GA_733 to 4.5.6_GA_1044
...

so I have to assume I'm missing some LDAP schema update now. After proceeding with a seemingly normal update, it has stopped now stopped again at the main menu:

Main menu

  10) zimbra-spell:                            Disabled                      
   r) Start servers after configuration        yes                           
   s) Save config to file                                                    
   x) Expand menu                                                            
   q) Quit

Going into the sub menus here, e.g. for the store, it looks like all the old
settings are gone. Yikes, this is getting somewhat ugly.

Ufff, got off lightly today. I forcefully terminated the previous installation session and started install.sh again. Much to my surprise and relief it ran like a champ and my server is up and running again. Everything still seems to here.

Thanks, Zimbra, for an apparently pretty bomb proof upgrade procedure!

Well, what else is there to say than Editorial: TAKE TIME TO BACKUP
(although thankfully I didn't need it today)
