You're right, it was around 200 MB on each OSD (so in total 3,2 GB). Double restart of the OSDs fixed that. Can this log file keep 0-byte files alive? In other words could this LOG file be the reason for the missing 840 GB - or did you think that the log itself might be in the GB range? Anyway, already thanks for the hint about the log file. We'll keep an eye on that one and try to upgrade to Hammer soon!
