Sometimes it can work its way through it, sometimes it failes. Seems to happen more reliable if the two disks used for this have different speeds. Happens even if disk IO is down to 5 MB/sec and newfs is niced to -20. >How-To-Repeat: clean install made ccd kernel configured ccd device newfs -> hungs >Fix: do not use newfs on ccd devices 8-} >Audit-Trail: >Unformatted:
