Subject: [Ozone-users] fixing a corrupted cluster

I had a disk problems corrupt one of my cluster files
(ozone/data/46185717.cl).  Rebuilding the nameTable.wizard, I hit:

Nov-21 16:15 WARN   [main] WizardStore - exception while loading
cluster: 46185717 (java.io.UTFDataFormatException)
Nov-21 16:15 DEBUG  [main] WizardStore -
        <snip stack trace>
Nov-21 16:15 INFO   [main] WizardStore -         cluster is unable to
read - should be deleted!

Now (as a result?) I'm hitting "org.ozoneDB.ObjectNotFoundException No
such object" as I traverse my data.  I'm wondering if someone can give
me some guidance to repair this. =20

I'm wondering how safe it is to restore that cluster file from a recent
backup. I'm going to try using backups to see.  Most of the objects in
my system are infrequently updated;  mostly new objects are added and
collections grow, so I am less worried about object values as I am about
getting those "missing" objects back.

For WizardStore, is it safe to assume objects generally reside in the
cluster they were created?  and  are objects added sequentially to a
cluster until it's size cap is reached, then a new cluster is added?

thanks for any help you can offer!
