So, I think there will be no help.
So please tell me:
Is it possible to build a system from scratch and to include all our user-data, all the files from our users?
I got clean backups of all files.

cheers

so, i thank you all for your help. i m sorry for not beeing so experienced with afs/kerberos. it s pretty new to me. by now, my first server, the one that was broken, is running pretty good and everybody gets their files, but still the database needs rebuilding and i dont know how.

the second one, that worked well until the other began running again, is in a bad state. nobody can connect to their files and i m not able to get a ticket from kerberos.

bos status -server myserver2
bos: no such entry (getting tickets)
bos: running unauthenticated
Instance fs, currently running normally.
   Auxiliary status is: file server running.
Instance ptserver, currently running normally.
Instance vlserver, currently running normally.

and logs:
==> /var/log/openafs/PtLog <==
ptserver: Unknown code pt 11 (267275) Can't rebuild database because it is not empty

please tell me how to rebuild the database.

The system on myserver (the first one) is now running again but if i try to create a user i still get: pts: database needs rebuilding ; unable to create user TESTUSER with id 3563
Volume 536872154 created on partition /vicepa of myserver
Released volume cell.user successfully
fs: Invalid argument, possible reasons include:
        -File not in AFS
        -Too many users on access control list
        -Tried to add non-existent user to access control list
pts: User or group doesn't exist ; unable to add user TESTUSER to group TESTGROUP pts: User or group doesn't exist ; unable to add user TESTUSER to group TESTAFSUSER
Added replication site myserver /vicepa for volume user. TESTUSER

Could please someone tell me how to rebuild the protection database?
I cant bos on myserver2 because i dont get a ticket from kerberos.
or does /etc/init.d/openafs-client stop and /etc/init.d/openafs- fileserver stop the job to stop the whole system?

thanks all for your help

code 5376 means no quorum elected. Are you sure your database servers are all running?

Try "udebug <server> 7002" for the ptserver
and "udebug <server> 7003" for the vldb

damn! i did not do anything on that second one!
Just to make sure you're working on the correct file:
As I understand you first deleted the file /var/lib/openafs/db/ prdb.DB0. This file was then probably recreated when you restarted the ptserver. Run this command on the backupfile you made first (or better on a copy of the backup file).

Thanks for your answer.
Well I found the file prdb_check. It doesnt print any errors. Only
thing I can find is with
./prdb_check -database /var/lib/openafs/db/prdb.DB0 -uheader - verbose
this line:
Ubik header size is 0 (should be 64)

So there are no errors! I can start the server and everything runs
fine but the machine wont mount /afs!

Hello,
well, there is a file called db_verify.c in the folder
/usr/src/modules/openafs/ptserver but I don' know how to build it.


If I recall correctly, db_verify gets renamed to 'prdb_check' during
the install, so you should check for the existence of that file.

If you can't find it, you'll need to build it from source code: the
directions on the AFSLore wiki are a good place to start:

http://www.dementia.org/twiki/bin/view/AFSLore/HowToBuildOpenAFSFromSource

If you have problems building openafs-stable-1_4_x, you could get
openafs-stable-1_4_7 instead, as that is the latest official release.

Once you have built the tree, src/ptserver/db_verify should get built, so you can simply copy it out of the source tree for your use. If it doesn't get built automatically for you, you can cd into src/ ptserver
and do a 'make db_verify' manuall.

Also, feel free to ask for help here  or on the irc channel.
