Repair Lotus Domino server 'Cannot write or create file' error

Discover what steps you can take if your Lotus Domino server runs out of disk space and you have issues sending and receiving Lotus Notes email messages.

My Lotus Notes Domino server ran out of disk space, and now several mailboxes are experiencing issues receiving and deleting email messages. We receive the error message, "Cannot write or create file (file or disk is read only)." I've checked file permissions and they seem fine. What do you think is the problem?

As you've discovered, bad things happen when you run out of space. I would suggest downing your Lotus Domino server and removing any *.tmp files and the log.nsf. The log might be corrupt, and if so, you won't be able to write any transactions. This also will cause errors.

The worst-case scenario is that the mail files might need to be compacted or restored from tape. This situation is an example of why it's important to have proper monitors running against your Lotus Domino server and hardware. Situations like this can cripple you for days while you try to repair the problem.
