By the way, I think this is worth an entry in /usr/src/UPDATING. Oh, and is it possible to share the filesystems on ccd or vn with 1.8.x installation after running `dd' command? > > If your CCD or VN mount was using an MBR before, then no changes are > > needed.. it should just work.

I followed the instruction, and now I get no error messages when I access /dev/ccd0, but zero bytes can be read from/written to it. The `dd' command gave me the following output: # dd if=/dev/zero count=1 bs=512 of=/dev/ccd0 dd: /dev/ccd0: end of device 1+0 records in 0+0 records in 0 bytes transferred in 0.000056 secs (0 bytes/sec) is this expected? I changed my /etc/ccd.conf to look like this: ccd0s0 1152 none /dev/ad0s1e /dev/ad1s1e ccd1s0 16 CCDF_MIRROR,CCDF_UNIFORM /dev/ad0s1g /dev/ad1s1g However, I still can't access neither of the filesystems on ccd devices. I hope I haven't missed anything. Thanks.
