i need to upgrade a disk
i have a system that is FreeBSD 6.2-PRERELEASE, that i need to upgrade its single disk. id like to keep all its existing slices the same size, and then use the unused space to create a new /opt slice. would dd be the way to go? if so, could someone advise on its proper usage for duplicating one disk to another? or, if there is an alternative way to skin this cat, im willing to learn whatever way might be the best. cheers, jonathan ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Start by reading the FAQ entries on How can I add my new hard disk to my FreeBSD system? and How do I move my system over to my huge new disk?. They'll give you some good options. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Use fdisk or sysinstall to create a disk label on the new disk with the partitions sized and named as you want. Then run: dd if=/dev/ad0s1a of=/dev/ad1s1a bs=64k ...for each partition (except swap), where you would use the appropriate device names-- if is the source, of points to where you are writing to. It's best to do this in a shell after booting off a FreeBSD CD, so that the on-disk filesystems are not actively mounted when you copy them. The FAQ has a more complete discussion and alternatives like using dump and restore, I believe. -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

No. I presume you mean that you want to switch to a larger new disk. If you can plug it in while the other one is still in place, then use fdisk, bsdlabel and newfs (you can do this from within sysinstall if you want, but using them by themselves is not really hard) to make your primary slice and divide it in to the partitions you want and build the filesystems in the partitions. Mount the new file systems to temporary mount points such as /newroot /newusr, whatever, then mount them. Then use dump/restore to transfer the contents of the filesystems to their new homes. It would look something like: cd /newroot dump 0af - / | restore -rf - cd /newusr dump 0af - /usr | restore -rf - etc for whatever partitions you want to move. Preferably this dump/restore would be done in single user with all files systems mounted and 'swapon -a' Once you are done moving all file systems, shutdown, move the drives and reboot. This will get you the copied file systems you want and dd might not. jerry or, if there is an alternative way to skin this cat, im willing to learn whatever way might be the best. cheers, jonathan ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
