Description:
We have a 6 node 3 replicas cluster and when I try to start a backup from the Mgmt-client I get this message:

ndb_mgm> start backup
Waiting for completed, this may take several minutes
Node 1: Backup request from 7 failed to start. Error: 1304
Start of backup failed
*  3001: Could not start backup
*        Sequence failure: Permanent error: Internal error
ndb_mgm> quit

How to repeat:
The cluster was restarted after a router crach but not the mgmt server.

can you try "ndb_select_all -d sys SYSTAB_0" and upload result here ?

also please upload cluster log and config.ini ?

Is this repeatable ?

Have uploaded the cluster log (bug-data-22698.tar.gz)

If you need additional info about what has happened you can try asking Stewart Smith, he was doing debug stuff there last week. He might have left something in debug mode.

We have not managed to reproduce it.

We would need a repeatable test case for bug #22698. It can't be repeated currently.

Unfortunately I have not been able to repeat this sins we now are using a two replicas cluster. Or is it fortunately!
