On FreeBSD 5.3-RELEASE, we have mounted slices as follows: -bash-2.05b$ mount /dev/ad0s3a on / (ufs, local) devfs on /dev (devfs, local) /dev/ad0s3e on /tmp (ufs, local, soft-updates) /dev/ad0s3f on /usr (ufs, local, soft-updates) /dev/ad0s3d on /var (ufs, local, soft-updates) devfs on /var/named/dev (devfs, local) /dev/ad0s5 on /drive_d (msdosfs, local) /dev/ad3s1d on /tmp (ufs, local, soft-updates) /dev/ad0s3e was 500MB /dev/ad3s1d was 40GB In /etc/fstab, we specified the mount point for both to /tmp. We then wrote a 1GB file to /tmp and there was no error. The file was successfully written. Can an expert with disks tell me where the file was written? How did the system decide where to write the file? How did it "select" /tmp in this case? Linux guys have talked about "disk spanning" using the method we just tested. I am wondering the dangers I face doing such a thing!!
