It took almost 2 hours to run but found no errors. There was only a few "Debug: pmap_interlock 00010003" lines in dmesg output. > But beyond that, think back about things you might have done > in the past that is outside the norm for HAMMER operations > that might have caused the problem, such as add or remove > a volume or adjust the disklabel or something like that. Nothing so extreme. I have updated the system to the latest 2.6 a few days ago. I think the previous version didn't have the new REDO code. I also briefly ran a DragonFly-2.6/x86-64 test installation from another disk and used the existing 500GB drive /home PFS. The error messages appeared the following day. -- Francois Tigeot
