How databases can suddenly dissapear

We had this case recently where a mailbox just disappeared. Upon further investigation, we found something like this in the logs:

05/12/2008 05:06:38 PM Compaction failed: Unable to bring e:\Lotus\Domino\Data\mail\someuser.nsf back online.: File does not exist
05/12/2008 05:06:38 PM Compaction failed: Unable to rename e:\Lotus\Domino\Data\mail\someuser6.TMP back to e:\Lotus\Domino\Data\mail\someuser.nsf: File is in use by another program – You must rename it yourself.

Then we found this IBM technote:

which is entitled “Databases Are Left with .TMP Extensions After Running Compact -c or -L”

After looking in the temp folder, we found the database and were able to rename the filename.

We suspect that the cause is a backup program which coincidentally is running on this database or the temp file at the same time that compact is running.

    Be sure your db did not just disappeared. This happens only in MS world :)
    compact -c actually compacts ur dbs by creating copies. This means a copy is created and old db is deleted. If something like a backup software got in the way while you were compacting, then …. it’s not the software’s fault :)
