Db failure, but can't figure out why
[This originally posted on May 14, but went into Transformer because I wasn't a member of the project blog.]
JJ called to report that after uploading a file (STOW3) into the topics folder in the db, a whole set of files stopped working -- in fact almost all the content is unavailable except for that file. We tried everything, including shutting down and restarting the db, and dumping out an re-uploading all the data, but no joy; it seems a complete mystery. One possibility is that a file has been accidentally deleted -- this has happened before -- but I can't find any backup of the db against which the current db contents could be compared. There must be one somewhere, but I've search Stew's machine and can't find it.
There is a set of XML files up on the Lettuce account in /home1t/london/xml, but that's not complete; I see only two files in the root directory but the db itself currently has eight. So Greg and I are at a loss, and I have to leave soon; I'm going to have to leave it with him.
