I/O error trying to recover log backup

Now I get the following error trying to recover log backup. The log files
are present, they are called BURVIS_LOG.001 and BURVIS_LOG.002, owner sdb
user. I have a suspicion that this is because there is no log volume file
itself in the directory (LOG_001). However I don't know why that is. There
is also no log volume file (physically) on my master database, although I've
created it in Database Manager and it shows there in the GUI.
