Comment 37 for bug 1093918

yes - the name was misspelled -- the correct name is via_jahhchjje3 and not via_hehhchjje3
but i only end up with different error message
-
sorry that it took longer - i deleted whole raid by error and built it new ... i made backup of all partitions with fsarchiver before and do currently recover the raid ... os's are back ... only data to copy .. can do later

josef@josef-maxtor-quad:~$ sudo dmsetup remove /dev/mapper/via_jehhchjje3
device-mapper: remove ioctl failed: Das Gerät oder die Ressource ist belegt
Command failed

"Das Gerät oder die Ressource ist belegt" means device or resource is busy
but no partition is mounted :(
