Hi folkes! Is there any way to do this with FreeBSD? Background: I have to admit, that I have never actually done or even tried this with any OS whatsoever. I am running a two drive system with two mirrors on it. Because I wanted a lot of room for /usr while /usr/home ist mounted on a different partition, the second drive is filled with the two mirror partitions, /usr and a swap partition. Everything else is mounted on the first drive. That being: /, /temp, /var, /usr/obj and the second swap partition. Together with the two mirrors this means seven (in words: 7) partitions. The table looks like this: Filesystem Size Used Avail Capacity Mounted on /dev/da0a 501M 72M 389M 16% / devfs 1.0K 1.0K 0B 100% /dev /dev/da0d 1.9G 102K 1.8G 0% /tmp /dev/da1f 21G 2.9G 17G 15% /usr /dev/da0h 6.8G 742M 5.5G 12% /usr/obj /dev/da0e 4.8G 71M 4.4G 2% /var /dev/mirror/sec1.eli 9.8G 7.5M 9.0G 0% /usr/home /dev/mirror/sec0.eli 34G 21M 32G 0% /usr/home/christian What really sounds (and probably is) pathetic is that I have nearly 6 gigs of 'leftover' space on da0. Increasing the size of the mounted partitions isn't really useful anymore (apart from reducing the free space) as I for example probably won't be needing 2GB for /temp or more than 5GB for /var - those are the sizes I have allocated now. Making / any bigger than the current 512MB wouldn't bring any advances either. Increasing the size of the mirrors isn't an option because that would be schrinking /usr. Finding a new mount point wouldn't be a problem. I was thinking something along the lines of /usr/ports. /usr/src was an idea at first but since I want to keep that on a different physical drive than /usr/obj, the idea doesn't seem that bright anymore. But the problem is that I can't allocate another partition, not that I ran out of ideas for mount points. :-) On other machines with IDE-drives I had one slice with partitions inside and never ran into this limitation before. Is there any way to do something like that on SCSI-drives? We are talking about SPARC64 here. Regards Chris
