I hadn't had need to use the cdrom since early December, so I was surprised when I tried to mount a cdrom and got the error message "cd9660: device busy." I had a lot of trouble with the cdrom not being detected under 4-STABLE, so have stuck with 4.1-RELEASE. The cdrom was working fine and I don't know of anything that's changed. The cdrom is used as an NFS filesystem by another server, but is not automatically mounted -- it is currently *not* mounted on the other system. Mountd is running. I have the following line in /etc/fstab: /dev/acd0c /cdrom cd9660 ro,noauto 0 0 From dmesg: acd0: CDROM <CD-ROM Philips PCA402CDA> at ata0-slave using PIO4 I've tried the commands mount /cdrom mount -t cd9660 /dev/acd0c /cdrom mount_cd9660 /dev/acd0c /cdrom All with the same result: device busy. I tried going to /dev and rm acd*, followed by ./MAKEDEV acd* Is there a utility which will identify which processes are using which files/devices? I ran across a posting in Deja News that Sun has a utility called fuser that does this, but it doesn't exist (at least under that name) in FreeBSD. Cand anyone suggest other troubleshooting steps I might take, or any tutorial which discusses possible causes of obscure error messages?
