While more redundancy (i.e. a third database server) is always a good idea, it is not strictly necessary, much less 'a bad idea to run with two database servers'. Agree. The host with the lowest IP gets an extra half vote, so there is never a draw. But back to your problem. I would tackle it like that: Set up a new DB host. Wait for it to replicate. Check that replica is OK. (1) Shoot original down. Erase database on original. Take first one up again and let it replicate back. Harald. (1) If the error replicates we have another problem, but let's first try this, ok? ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info

I *think* it has been fixed now. Not really a bug. If the lowest numbered DB server goes AWOL the remaining server has no chance to become master. I cannot distinguish (without human help) wether there is a simple communication problem or if the lower server really is down. So it stays in RO-Mode, as it should. As an admin you then have the choice to go back to a single-server scenario, or bring the other one back online. I do agree however that this is not too nice, and you are probably better off with three DB servers. Dipl. Chem.

So I used our backups from the last weekend and now the machines are running again. Now we are able to create new users and other things but there's still the problem with the database. Could someone please tell me how to rebuild/repair the database without loosing all data in it? Thanks for your help!

Can you reboot it? Once mounting fails you need to start with a fresh load of the kernel module, and it's not going to unload. I assume the root.afs volume is not on the same server, or, if it is, you're doing something clever like delaying client start until the server is running? If not... fix that?

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.

Are you sure your database servers are all running?

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).

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! kanou Am 23.07.2008 um 17:26 schrieb Steven Jenkins: On Wed, Jul 23, 2008 at 10:51 AM, kanou [EMAIL PROTECTED] wrote: 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.

[OpenAFS] Serious trouble, mounting /afs, ptserver, database rebuilding
Hello, i realy need some help. If I can't get this mess fixed I will be in serious trouble. Our AFS is running for more than 5 years, but I just joined the company a few weeks ago - so I'm pretty unexperienced with AFS. It started last week. There were messages like this: pts: database needs rebuilding. So I stopped the server with something like bos stop -server myserver -instance ptserver and did something perhaps not pretty good: Made backups of /var/lib/ openafs/db and deleted prdb.DB0 and prdb.DBSYS1. Restart: bos create -server myserver -instance ptserver -type simple -cmd /usr/ lib/openafs/ptserver That did it. The systems broken. Starting afsd prints: afsd: Can't mount AFS on /afs(22) The logs print: == /var/log/openafs/FileLog == Tue Jul 22 21:43:39 2008 Couldn't get CPS for AnyUser, will try again in 30 seconds; code=267275. and this: == /var/log/openafs/PtLog == ptserver: Unknown code pt 11 (267275) Can't rebuild database because it is not empty So playing back the prdb.DB0 and prdb.DBSYS1 and restarting the server didn't help. Please help me. Sincerely kanou ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
