Re: UserID's clearing after reboot

This is no longer an issue...at least in regards to *corrupted* data and
attempting to recover it.  I've restored database files from a recent
backup.  The users are now back as they were.  I'm back to focusing on why
this is occurring after every reboot.  I've setup a similar configuration on
another Linux server, rebooted it and all the users I created are there.

I'll resubmit more questions if I have any on that.

Thanks again,
Ryan

Kurt,

Thanks for the advice.

I first stopped ldap & slapd and then ran 'db_recover -v' while in the
directory for ldap (/var/lib/ldap) and received the following:

db_recover: Finding last valid log LSN: file: 1 offset 415705
db_recover: Recovery starting from [1][415564]
db_recover: Recovery complete at Wed Jul 12 07:32:44 2006
db_recover: Maximum transaction ID 800000da Recovery checkpoint
[1][415705]

I then restarted ldap & slapd, however nothing changed.  I then attempted
to add a user that I knew was there before, using ldapadd and received a
statement that the user already exists.  When using a GUI such as LDAP
Admin, I don't see the user(s) listed.  I can grep the files in
/var/lib/ldap for users and I receive results back.  For some reason these
files are not being read by the GUI, but are seen by ldapadd.

I tried using 'db_recover -c -v', but receive:

db_recover: Finding last valid log LSN: file: 1 offset 424467
db_recover: Recovery starting from [1][28]
db_recover: Log sequence error: page LSN 1 416496; previous LSN 1 558401
db_recover: Recovery function for LSN 1 416216 failed on forward pass
db_recover: PANIC: Invalid argument
db_recover: PANIC: fatal region error detected; run recovery

db_recover: PANIC: fatal region error detected; run recovery
db_recover: PANIC: fatal region error detected; run recovery
db_recover: DB_ENV->open: DB_RUNRECOVERY: Fatal error, run database

Any further suggestions are very appreciated.

Thanks,
Ryan
