>Description:
Following the enabling of MBR/disklabel wedge support, "ccd" devices
configured with traditional device-path component names fail:
#
# /etc/ccd.conf
# Configuration file for concatenated disk devices
#
# ccd ileave flags component devices
ccd0 32 none /dev/wd0p /dev/wd1p
and subsequent attempts to access (such as the boot-time fsck)
report "device not configured" and eventually an unexpected
inconsistency causing multiuser boot to be aborted.
>How-To-Repeat:
On a system with a "ccd" device configured using traditional device
paths similar to that shown above, boot a kernel that has MBR/disklabel
wedge support enabled.
>Fix:
At this time, changing the components to "/dev/dkN" (as found in
'dmesg' output) appears to be the only way to achieve working "ccd"
devices:
#
# /etc/ccd.conf
# Configuration file for concatenated disk devices
#
# ccd ileave flags component devices
ccd0 32 none /dev/dk6 /dev/dk7
Interestingly, once configured, partitions on the "ccd" device are not
then associated with any "/dev/dkN" wedge devices.
It would be nice to have the old device names continue to work, and for
'ccdconfig' to grow "NAME=..." support.
