Following URL:

The line with ndb_restore options:
 ndb_restore [-c connectstring] -n node_id [-s] [-m] -b backup_id -r [backup_path=]/path/to/backup/files [-e]

[backup_path] should be [--backup_path]

Otherwise it thinks it's part of the file.

How to repeat:
shell> ndb_restore -n 4 -b 1 -m -r backup_path=/data2/users/geert/cluster/master/BACKUP/BACKUP-1/
Nodeid = 4
Backup Id = 1
backup path = backup_path=/data2/users/geert/cluster/master/BACKUP/BACKUP-1/
Opening file 'backup_path=/data2/users/geert/cluster/master/BACKUP/BACKUP-1/BACKUP-1.4.ctl'
Progress reporting degraded output since fstat failed,errno: 9
Failed to read backup_path=/data2/users/geert/cluster/master/BACKUP/BACKUP-1/BACKUP-1.4.ctl

Correct version:

shell> ndb_restore -n 4 -b 1 -m -r --backup_path=/data2/users/geert/cluster/master/BACKUP/BACKUP-1/
Nodeid = 4
Backup Id = 1
backup path = /data2/users/geert/cluster/master/BACKUP/BACKUP-1/
Opening file '/data2/users/geert/cluster/master/BACKUP/BACKUP-1/BACKUP-1.4.ctl'
Backup version in files: ndb-6.3.11 ndb version: mysql-5.1.31 ndb-6.3.22

Suggested fix:
Small update in the docs.

It's a Docs bug, so I've changed the Category and Lead to match.

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.

NOTE: The syntax changed in 5.0.38/5.1.17/NDB-6.1.7 (but not in 4.1.X) to conform better with how other MySQL program options work. I've updated the documentation accordingly.
