Done: Filesystem kbytes used avail capacity Mounted on /dev/md/dsk/d5 19584720 9536 19269332 1% /ftp-root /dev/md/dsk/d6 15667560 6120 15172028 1% /lxr-root d5 (/ftp-root) is a raid5 volume; it is "reliable" but slow. d6 (/lxr-root) is a simple stripe volume. It is fast but not safe; if even a single disk crashes, you will lose all the data on it. Both volumes have vxfs filesystems with delayed log commits for performance; in the case of the ftp volume it should not be written often and in the case of lxr, it's probably not important if you lose the tail end of the log after a crash anyway. I strongly recommend setting up a jail for the anonymous ftp area, similar to what we did for cvs. I've extended the jailsh frob we use for mirroring via rsync a bit so that you can specify the root on the command line (and improved the syslogging a little bit). I'll check it in tomorrow.
