Now comes business as usual: Initializing the new pseudo disk ar1 with fdisk fdisk -BI /dev/ar1 It is recommended to use this method for new disk installs. This setup will allow your disk to work correctly with other operating systems that might be installed on your computer and will not confuse other operating systems' fdisk utilities. Ja, this is looking good Configuring the RAID If that is not what you want, use the BIOS to create the arrayĭisk scheduler: set policy of ar1 to noopĪr1: disk0 READY (master) using ad8 at ata4-masterĪr1: disk1 READY (master) using ad10 at ata5-masterĪr1: disk2 READY (mirror) using ad12 at ata6-masterĪr1: disk3 READY (mirror) using ad14 at ata7-master WARNING!! - Using FreeBSD PseudoRAID metadata WARNING!! - not able to determine metadata format Let's check what happened and look into the logs. If you have not much space natacontrol will automatically adjust the stripe to a minor number (to 64KB a.e.) The 128 is the interleave I used - which should be reasonable for this kind of setup. Interestingly RAID10 is accepted, I think it is just a synonym for RAID0+1. Let's dive into real world practice and setup the RAID with a simple command: # natacontrol create RAID10 128 ad14 ad12 ad10 ad8 The RAID will be created of the individual disks namedĪs I only have 4 1TB disks I think RAID0+1 is the best solution as mentioned above. In case the RAID has a RAID0Ĭomponent, the interleave must be specified in number of sec. Looking at the man page of natacontrol(8) we see our software RAID options: create Create a type ATA RAID. Certainly there are other maybe better ones around, like the RAID60 or even RAID50 but we have to consider what the nata(4) driver offers and that I only have 4 disks. You can look around on the internet for various Raid calculatorsĪ very helpful page for general info is this one:Īs I want to have a Backup Fileserver I am choosing a VERY HIGH fault tolerant kind of RAID10 thing. You could also use the devattr command: devattr -m driver:diskĭevattr -d ad* # for example Choosing the right RAID Kern.disks: ad14 ad12 ad10 ad8 da0 da1 md0 So attach it first! You can operate on the channels with the following commands: natacontrol info channelĭo it, until natacontrol can list all single disks you are going to use.įor further investigation you can try out other commands to find the disks:Īlso look out for the disks sysctl kern.disks ad14 Problems finding the disks?īut you see the controller in the dmesg message?įirst, maybe natacontrol doesn't find them because the ata channel is not attached. Let natacontrol look out for our possible drives su-4.2# natacontrol list Identifying the disksĪfter booting up the system please check that the Adapter you are going to use is correctly found.ĭmesg reveals: atapci1: port 0xe100-0xe10f,0xe110-0xe113,0xe120-0xe127,0xe130-0xe133,0xe140-0xe147 mem 0xfe4a1000-0xfe4a13ff irq 21 at device 0.0 on pci1 Please make sure that the adapter is not configured (after the BIOS just before dfBSD starts) with RAID - just expose the disks individually to Dragonfly.
