Hi, I'm having massive problems getting ccd to run on my 2.1.5 machine. When I try to ccdconfig -C with the ccd.conf file below and the 2 ~1Gig SCSI drives ( disklabels also shown below ). I end up panicing my machine with the message: vm_bounce_alloc: b_bufsize(0x0) < b_bcount(0x200) !! panic: vm_bounce_alloc A trace in the debugger shows the following: _panic _vm_bounce_alloc _sd_strategy _scsi_strategy _sdstrategy _spec_strategy _ccdstart _ccdstrategy _correct_readdisklabel _ccdgetdisklabel _ccdioctl _vn_ioctl _ioctl _syscall _Xsyscall Can someone see anything wrong with what I am trying to do? Also, how many cylinders should I leave unused at the start of the disk if I'm using ccd? Many thanks in advance Gavin # ccd.conf #ccd ileave flags components ccd0 16 none /dev/sd0e /dev/sd1e disklabel of sd0 # /dev/rsd0c: type: SCSI disk: sd0s1 label: flags: bytes/sector: 512 sectors/track: 1 tracks/cylinder: 1 sectors/cylinder: 1 cylinders: 2074880 sectors/unit: 2074880 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 2074880 0 unused 0 0 # (Cyl. 0 - 2074879) e: 2074780 100 4.2BSD 0 0 0 # (Cyl. 100 - 2074879) disklabel of sd1 # /dev/rsd1c: type: SCSI disk: sd1s1 label: flags: bytes/sector: 512 sectors/track: 1 tracks/cylinder: 1 sectors/cylinder: 1 cylinders: 2134305 sectors/unit: 2134305 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 2134305 0 unused 0 0 # (Cyl. 0 - 2134304) e: 2134205 100 4.2BSD 0 0 0 # (Cyl. 100 - 2134304) -- []-------------------------------------+--------------------------------------[] | Gavin Cameron | Ormond College | | Ph : +61 3 9344 1201 | The University of Melbourne | | Fax : +61 3 9344 1111 | Parkville, Victoria | | Email : gavin@ormond.unimelb.edu.au | Australia, 3053 | []-------------------------------------+--------------------------------------[]
