That is pretty well documented in the handbook, FAQs and online publications. A brief rundown is: You don't have to literally "reformat" it. That is a low level process done at the factory and normally not redone. But, we know what you mean - you want to do whatever is necessary to use it in FreeBSD and don't care what the process is actually called. NOTE: If it is SCSI the name is da1: if IDE/SATA it is probably ad1: ALSO NOTE: I am presuming you do not intend to make this disk bootable. If you do, add a -B flag to the fdisk and to the first bsdlabel NOTE too: This all must be done as root. First: use fdisk to create one slice (da1s1) of FreeBSD type on it that occupies the whole disk. dd if=/dev/zero of=/dev/da1 bs=512 count=1024 fdisk -I da1 the dd wipes out old stuff. It might not be needed, but is easy just to make sure. Second: use bsdlabel to write the partitions in that slice. Partition layout Depends on how you want to use it. For example, I will use one chunk of extra swap and two mountable partitions d & e. bsdlabel -w da1s1 [this puts the base label there] bsdlabel -e da1s1 [this puts you in mode to edit partitions] you will then see something like this: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c:335544320 0 unused 0 0 # "raw" part, don't edit Edit it to look something like: 8 partitions: # size offset fstype [fsize bsize bps/cpg] b: 2097162 0 swap c:335544320 0 unused 0 0 # "raw" part, don't edit d: 33554432 * 4.2BSD 2048 16384 8 e: * * 4.2BSD 2048 16384 28552 This will give you a 1 GB swap partition, a 16 GB da1s1d partition and a da1s1e partition that takes up all the rest of the disk. NOTE: The numbers under size and offset are in 512 byte blocks. You can use values like 16GB, but this was is consistent. NOTE too: When you use * for offset and the final size, bsdlabel calculates them for you - correctly. But you can specify them yourself if you want - if you are doing something weird like leaving a hole in the middle or whatever. Third: You must run newfs on the two mountable partitions newfs /dev/da1s1d newfs /dev/da1s1e Nowdays the defaults are generally good for most usages, but there may be times you need to adjust them to get more inodes if you have a large filesystem with lots of vary small files. NOTE: newfs seems to want the full device name still, even though fdisk and bsdlabel now will fill in if you just give them da1 without /dev. Fourth: You must create mount points for the mountable partitions. Say you want to mount them as /work and /scratch, then mkdir /work mkdir /scratch Fifth: You must edit /etc/fstab to add lines for each of the three new partitions. The swap should look like your existing swap line with the new device name, something like: /dev/ad0s3b none swap sw 0 0 The mountable partition should look about like one of the other mountable partition lines but with the new names: /dev/da1s1d /work ufs rw 2 2 /dev/da1s1e /scratch ufs rw 2 2 Thereafter, it should all work just fine and dandy. Again, note, these examples are for SCSI. For IDE/SATA the device names would be ad.... in place of da.... such as bsdlabel ad1s1 and /dev/as1s1d for mounts. The documentation is quite complete on this. You should do some reading. ////jerry > > Thank you > Cyrus > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
