Hi Peter, Thanks for reporting this. I am now facing the same error, but I don't get it.... For example: normally it appears when I try to change something in the DB (e.g. adding a new history), but then suddenly I managed to create one new history item....and now it is occurring again. It seems to be a transient locked state, so every now and then the lock is released somehow. Anyway, are there any ideas on what could be a real solution to this problem? This is the second Galaxy server I upgrade which now is stuck after the upgrade...any help is appreciated! Thanks and regards, Pieter. -----Original Message----- From: galaxy-dev-bounces@lists.bx.psu.edu [mailto:galaxy-dev-bounces@lists.bx.psu.edu] On Behalf Of Peter Cock Sent: donderdag 31 oktober 2013 11:54 To: Galaxy Dev Subject: [galaxy-dev] New Galaxy won't start, SQLite (OperationalError) database is locked Hello all, While attempting a fresh Galaxy install from both galaxy-central and galaxy-dist, I ran into a problem initialising the default SQLite database (database/universe.sqlite), $ hg clone https://bitbucket.org/galaxy/galaxy-dist ... $ cd galaxy-dist $ ./run.sh ... galaxy.model.migrate.check DEBUG 2013-10-31 10:28:26,143 pysqlite>=2 egg successfully loaded for sqlite dialect Traceback (most recent call last): ... OperationalError: (OperationalError) database is locked u'PRAGMA table_info("dataset")' () After some puzzlement, I realised this was down to the file system - I was trying this under my home directory mounted via a distributed file system (gluster I think). Repeating the experiment under /tmp on a local hard disk worked :) (I'm posting this message for future reference; hopefully Google and/or mailing list searches will help anyone else facing this error) Regards, Peter ___________________________________________________________ Please keep all replies on the list by using "reply all" in your mail client.
