Log Shipping in a SQL CLuster

sql server replication:
I have SQL in a cluster with Log Shipping enabled to a remote DR server.

Yesterday, I did my regular security updates following KB article Q174799.
Now my log shipping job is out of synch and it looks like I need to re-create
it. What would have caused this given the database was never offline? Did
moving the group to the other server cause the transaction logs to get out
of order. I woulkd like to know what caused this I can avoid it next time.

Moving it to the other node doesn't affect the database at all. It does
take the SQL Server offline and then start it back up. But it is exactly
the same database and there is never a possibility of getting logs out of
order.

You would have to define what you mean by out of synch? Is it behind? Are
things accumulating? Are jobs not started? Can it not see the file share?

There is nothing to recreate. You have a job that backs up a database, a
job that copies files, and a job that restores a database. Recreating it is
going to hand you back exactly what you have right now.

It looks like something I did on the night I did the security updates caused
the file share on the source server directory to be removed. That in turn,
caused the copy and load delta to start increasing and the log shipping
monitor to say "out of synch"

I am not sure why or how the file share was removed. I enabled "sharing"
again on the source folder and the values are decreasing. I will see if this
will get back into synch.

Vincent,

OK...thanks!! What I have determined is anytime I failover the cluster the
directory that is setup as a "share" for the transactions logs is removed.
Not the physical directory itself the share properties...what is causing
that?? Thanks!

Hi,

It appears the following KB article can address your concern.

PRB: Cannot Modify Backup Network Share After You Change the Transaction
Log Backup Folder
http://support.microsoft.com/?id=314570

Let me know if the problem still occurs.

Vincent,

Would this KB Article still apply if the share directory is actually on the
EMC array. The share is not local to the server? When the fail over occures
the drive is mapped exactly the same during failover. Thanks!!
