I was following this discussion with the great interest but without intend to participate in it until today.
Namely one of my OpenBSD servers (5.6 sparc64) runs Mollify and last night I received an e-mail from an angry user who could not upload files (the upload will fail or upload the file with file size zero). After running df I noticed that /tmp was 100% full (4GB used) but the size of individual files was only 12Kb. I thought for a second and I remember seeing this with HAMMER on DF. Long story short I checked /etc/fstab and sure enough I had rw,softdep next to each partition including tmp. I removed softdep rebooted the sytem and /tmp usage dropped to 0%. More importantly users could upload files again. My questions is which partitions should be mounted with softdep option? Is there a way to prune metadata which will save me for problems like the one I encountered last night. Best, Predrag
