Re: Software RAID-1 - Swap partition

Can I shrink the mirror partition and have two swap partitions, or if that is not possible, how would I go about creating a "mirrored" swap partition?

RE: Software RAID-1 on FreeBSD 5.4
One last comment for you on software mirroring, While I am not trying to disparage the various efforts, software mirroring provides limited redundancy unless the hard drives are on separate busses. If you do the common thing of putting 2 IDE drives as the master and slave on the primary IDE controller, than all it takes is a buss error on the IDE bus and you have scrambled the data on both hard drives. The same problem exists if you setup a ccd or vinum or gmirror or whatever on a SCSI controller where the disks are all on the same SCSI bus. The same problem also exists on SATA controllers, and on cheaper hardware RAID cards where the disks are on a single IDE bus. This is why hardware RAID controllers are quite often better as the better ones contain multiple interfaces.

Last time I tried ccd it would work fine on dissimilar drives so long as the partitions (not slices) that are used for the mirroring were exactly the same size. -- Ean Kingston E-Mail: ean AT hedron DOT org URL: http://www.hedron.org/ I am currently looking for work.

Hello again, Thank you for all your answers ! I am going to look at gmirror and ccd. But I have a last question. My disks are differents. One is a Maxtor detected with a 111 GB capacity and the other is a Seagate detected with a 114 GB capacity. Will I have problems trying to use RAID with this configuration ?

Re: Software RAID-1 on FreeBSD 5.4
I have had a lot of sucess with ccd. Its pretty simple to configure. Basically, you just add the kernel device. Label the disks, do a ccdconfig ccd0 0 /dev/ /dev/. Then newfs ccd0 and mount it where you want it. Casey > Hello everybody, > > I have 2 120 Go Drives installed on my FreeBSD 5.4 Box. I want to create > with these 2 disks a software RAID-1 solution.

The Handbook is your friend: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/vinum-root.html Vinum is considerably more stable under FreeBSD than RaidFrame -- I'm not even sure that the people porting RaidFrame are ready to have people use it on anything other than development systems yet. Since, as you say, it's not supported on RELENG_5_1, then the only place you'ld have a hope of finding it is HEAD, and that's just too grisly to contemplate running a proper server system on. In fact, unless your hardware requires you to run 5.x, I'd strongly recommend that you stick with 4.8-RELEASE (or 4.9-RELEASE due out in the next few weeks). Using Vinum boot drives under 4.x is supported, but not quite so well integrated into the boot code as on 5.x. However, all it requires are a few extra twiddles in /boot/loader.conf as shown at the end of the referenced Handbook section.
