Title: Proper restore procedure 6.0.1 -> 7.0 [SOLVED]
Post by: kirkf on September 23, 2006, 07:11:40 PM

I'm trying to restore a backup from a 6.0.1 server to a fresh 7.0 install.  I've used variation of the script developed here:

http://forums.contribs.org/index.php?topic=31159.0

The users and data seem to be copied cleanly, but the pre-restore event seems not do what I expected.  The old and new passwd files are not correctly merged (some system users are missing afterwards).

When the post-upgrade runs, the S05imap-relocate-maildirs script returns:

esmith::event[27946]: Couldn't chdir User::pwent=ARRAY(0x9614ae4)->dir:No such file or directory

I've also observed that the mysql databases are not migrated properly.  

Can anyone suggest a procedure to try?  I'm not sure how to start troubleshooting this.

Please report any problems to the Bug Tracker, and give a full account of what you attempted and any steps you followed.

Yes, I usually do open a bug in such a case, but I think the problems here are out of the ordinary as the 6.0.1 system had several contribs, which I didn't have the opportunity to remove as hardware failure crashed the server.

I do have the full contents of /etc, /home, and a dump of the databases created with mysqldump, so I'm trying to patch it back together.

Turned out that nothing was wrong with the procedure.  The server that failed turned out to have had a user that was listed in the db as user-deleted, and for some reason the pre-restore event failed, so the new server's passwd file was missing key users.  In addition the imap-relocate-maildirs event during post-upgrade failed while attempting to process this user.  Once I removed that entry from the db, the post-upgrade completed properly, and the maildirs were in the correct format.  I had to fix the missing user entries by hand (useradd), copying the parameters from another SME7 box.

The missing users included:

haldaemon
nut
spamd
qpsmtpd

clamav existed, but had wrong uid, gid, home, and shell.

I suppose that the backup script should either ask the user to run (and verify) pre-backup manually or should check that it completes succesfully before continuing.

I think you were just probably missing a lot of user and password info.

re the need to do:

On the old sme6 server prior to shutting down do:
/sbin/e-smith/signal-event pre-backup

Yes, I wish I could have done a pre-backup.  Unfortunately the server had already failed before I started the recovery, and I only had the /etc and /home files and a mysql dump of all the databases...

All seems well now, though.  Based on what I've learned here, I'll have to refine the backup procedures to include the pre-backup step.

Thanks,
