You probably need a special driver. BIOS RAID is not real RAID; it falls under the category of "fake RAID." https://en.wikipedia.org/wiki/RAID#FAKE Essentially, a BIOS RAID is really a crappy software RAID implementation hosted on a chip. It is the worst of everything. If you need true RAID, then get a real RAID card (and be prepared to pay a decent amount). If you do not need real RAID, then setup your RAID as a pure software RAID managed from within Linux. If you use the BIOS fake RAID and your motherboard fails, there is a good possibility that you will not be able to to recover the data from your disks without another identical or nearly identical motherboard to which you can connect the drives. Linux software RAID, on the other hand, lets you plug the disks into any machine running Linux and assemle the array. Regards, -Roberto -- Roberto C. Sánchez

Debian 7 - No se instala Grub en Raid 0 con SSD
Hola, Tengo un problema con una instalación limpia de Debian 7. La instalación se realiza perfectamente, pero al llegar al punto de instalar el cargador de arranque (grub) no hay manera, da error fatal y no se instala. Por lo que he leído por ahí, el problema es que no sé el nombre del raid, y por lo tanto no se instala correctamente. En la caja de texto para introducir donde instalar el grub sale esto por defecto : /dev/md. Leí por foros que había que listar /dev/mapper para ver el nombre del raid, pero ahí solo me sale un archivo llamado control. Listando /dev/md, sí que me salen lo que parecen particiones del raid : md126p1, md126p2 , pero poniendo tanto la principal (md126) como la partición donde quiero ponerlo (md126p3), me da error fatal. Comentar también que en algún punto y en Windows al volumen del raid lo llaman Volumen_, y si pongo esto último (dev/md/Volume_) da error, pero en el error sale como que apunta a md126 (enlace?). Por ahora entro con un live cd (rescatux) que me lista los SO y me deja entrar, por lo que la instalación es correcta, pero no se graba bien el cargador de arranque. Lista de particiones y sus supuestos nombres raid 1- 100MB boot de Windows - md126p1 2- -100GB Windows 7 (NTFS) - md126p2 3- -20GB Debian (EXT4) - md126p3 4- 2048MB SWAP - md126p4 5- 100GB Datos (NTFS) - md126p5 Un cordial saludo y muchas gracias, Iván

Re: Vaio Z RAID 0
Hi Dan, the good news is that I can confirm that it is possibly to run Linux on a VAIO SVZ13, using the original Intel-RAID0 and without destroying the pre-installed Windows. The bad news is that the way I did it is probably not easy to follow for everyone, and it might require some luck (i.e. using the correct versions of everything, and in the right order). Unfortunately I cannot give you precise advice, but maybe telling you about my experiences installing Linux on this device will be of some help. However, in my case I did not install Debian Wheezy but Xubuntu 12.04. For this I had to use Ubuntu's alternate installer, which I believe behaves very similar to the Debian installer, although I guess there are some differences. But before running any installer, I actualled used a Linux-Live-CD (GRML 2012.05) to back up (using ntfsclone) and shrink (using ntfsresize) the Windows partitions and to repartition (using fdisk -uc) the Intel-RAID0. If I recall correctly, the original partitioning was: p1 = recovery p2 = Windows boot loader p3 = Windows 7 p4 = hibernation I deleted p1 and p4 and shrank p3. Later during the installation, I used p1 for the Linux / filesystem, and the space gained from p3p4 for /home. I do not recall having any trouble creating the filesystems. But if I had, I would have tried creating the filesystems manually via GRML, and then telling the installer to simply use the existing filesystems (which I believe is possible, but admittedely I'm not completely sure). For me the biggest snag was installing GRUB to the MBR, which requires giving the correct device name, i.e. /dev/mappers/isw_something or so. But in the end it worked, and dual-booting between Windows and Linux works fine so far. As such, I cannot confirm the statement from Julien's blog that this kind of RAID is not supported correctly by GRUB.

I use most of the time linux and not Windows. I am creating now the rescue DVDs. Windows 7 takes 5 DVDs!!! Best, Dan You need to use the Windows Disk Manager to shrink the windows partition because both the actual partition and the file system need to be adjusted. After doing this, you should check the partition for errors. Only then should you try to do anything else. Using RAID 0 (not really RAID because there is no redundancy) for a primary file system is a scary proposition. Both drives need to be working or your system is in deep trouble. Given that disk failures probably account for the majority of hardware problems, I personally would try to get rid of the RAID 0 entirely. To remove RAID 0, you may have to copy your Windows partitions to another drive temporarily, then try to break the array and copy the partitions back to just one drive. This means that you need to resize the Windows partitions so that they fit onto a 128G drive. Once you have your partitions copied, try booting from a live cd and use gparted to create new Windows partitions on one disk and Linux partitions on the other. Copy the Windows partitions back and try rebooting into Windows. This may actually require reinstalling Windows (do a repair-type installation so you don't wipe out your other Windows programs). Don't reformat the disks but do allow Windows to try to repair them if needed. And keep the copies of the original partitions until you have this working. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Si tu utilises mdadm, le problème ne se pose pas en ces termes car mdadm utilise les metadatas enregistrés sur les disques pour déterminer la place du disque dans l'ensemble raid. Donc déplacer les disques n'a aucune influence (ou autrement dit: les noms des disques n'ont aucune influence). Dans ton cas, si tu veux vérifier: - arrête le raid: mdadm --stop /dev/md0 (pa exemple) - copie la sortie de mdadm --examine /dev/sd?1 - arrête le système, déplace les disques, reboot sur un livecd _sans lancer le raid_ - copie la sortie de mdadm --examine /dev/sd?1 compare avec l'autre sortie: même si les noms des disques (/dev/sd?1) changent, leur checksum te permet de les reconnaitre, et tu verras qu'ils conservent le même numéro dans l'ensemble Raid.

Re: Instal·lació dual (win / linux) en u n disc dur doble de 2 TB Raid 0 Stripe (2 x 1 TB - 7.200 rpm)
Al meu SAI APC suposo que se li va morir la bateria després de no fer-lo anar durant més d'un any (ja tenia uns 4 anys)... Bueno, jo em vaig pensar que era la bateria, perquè allò no rutllava... I unes bateries noves casi valen tant com tot el SAI! Però si és per salvar el disc dur, jo faig el que calgui!! Algú pot confirmar lo dels SAIs i la vioda dels discs durs!

Segueixo comprant PCs subdesenvolupats, però els canvio la font per una més presentable. Deu fer sis anys que la vaig comprar, la migro cada cop que compro un PC nou, va costar 50 euros, fa menys soroll que les habituals i el PC (discs inclosos) funciona més feliç. Tot i que fa molts anys que no em miro les especificacions d'un SAI per casa, em sembla que el consum és força alt.

O és una altra cosa? 2) hi ha cap problema perquè quan m'arribi l'equip amb windows 7 jo deixi un disc dur amb el windows i posi el linux a l'altre?? Em trobaré el windows 7 tot al mateix disc dur o això de Raid 0 implicarà que el trobaré escampat per tot arreu com si fos un tumor? 3) Més en general, per instal·lar, i després treballar, amb linux, és més convenient aquesta configuració o agafar un disc dur de 1,5Tb sense històries de Raid 0???

This is usually done using a Floppy disk, but one can also 'slipstream' the whole installation, including drivers for SATA/RAID/SCSI controllers. Besides the fact that many Mobo Onboard RAID Controllers utilize and purport to be hardware' RAID, and while they do utilize a Chip (either part of the Chipset, or a Separate 3rd Party Chip) - they are usually software' based and run (emulated in a sense). I *guess* similar to what Winmodems do/did. Negating that circumstance - there's also windoze so-called Dynamic Disks, which ranges from using DynamicDisks as a LVM, to creating softRAID arrays - but which have many limitations as far as creating/breaking, setting up, reverting back to Basic Disk ...not to mention that I *think* one needs to use a *Server Based* Windoze installation (Win2K or Win2K3), just to set up a software RAID using XP.

Re: Need help installing RAID 0+1
Peter, thanks, I actually did use that guide to do the set-up, and it was very helpful. the problem I have is how do I move from having either a RAID0 or RAID1 to having BOTH. I have the four disks broken up into two RAID0 arrays of two disks each. what I want to do now is have the two RAID0 disks be 'mirrored' to each other - i.e. RAID1 when I try to use the Create MD It am told that I don't have any RAID partitions; but I can't set the RAID) partitions to physical RAID partition either. so that's where I am stalled out.

HW SCSI Raid 0 - Dog Slow...
Hello all, I have a Server that I have updated several things as of late. I upgraded the debian version to Sarge. I have built a new kernel version 2.6.8. I have upgraded the mother board and processor (Asus K8N - Sempron 3100+). Anyway I kept the old (3 years) Adaptec Model:2400A SCSI Raid 0 array, with IBM SCSI drives. I remember back when I put in this setup in the server it seemed like I had to put in a couple of lines of code in some config file to make it run at the proper speed. But being that was 3 years ago and my memory seems to be failing by the day I cannot remember what it was I did to make this raid array work like it should. And searching through all the Debian list archives have yielded nothing. The Raid array does work fine it is just slow. Here is a print out below. of the SCSI raid compared to the IDE on the same machine. Also included the partial output of the /usr/adm/dmesg about Adaptec 2400a. Any ideas on how to speed up this SCSI raid array?

Asus P4C800-E / Debian Sarge / RAID 0
Hallo Leute, ich habe mir ein Asus P4C800-E Mainboard zugelegt. Nun möchte ich meine beiden 80G Platten im RAID 0 betreiben. Das Board bietet nun zwei Möglichkeiten : 1. Intel ICH5R South Bridge des 875er Chipsatzes Hier können zwei Platten über SATA im RAID 0 betrieben werden 2. Promise PDC20378 Auf dem Board befindet sich auch dieser Promise Controller. Auch hier werden die Platten über SATA angeschlossen. Wird einer der beiden Möglichkeit z.Zt. überhaupt unterstützt? Wenn ja, welche und wie muß ich bei einer Neuinstallation vorgehen ? Zur Zeit habe ich meine beiden Platten an einem Promise FastTrak 100TX2 mit Debian Sarge und Kernel 2.4.26 laufen. Dies ist aber ein Upgrade von einem laufenden Woody, eine neue Installation einer Sarge CD erkennt den Promise Controller nicht. Am besten wäre es natürlich wenn ich meine beiden Platten direkt weiter betreiben könnte (ohne neue Installation). Ich denke aber da gäbe es nur bei der Installation mit dem Promise Chip eine kleine Chance.

Re: Software RAID 0 and linux 2.6.8.1
Well, definitely sounds like you know what you want :) Seems like my confusion between you saying software and hardware controller is, as Paolo was saying, the Promise FastTrak isn't a true hardware controller apparently. It still requires some software, ie. kernel module, on the software side to operate. This is, however, coNSIDerably faster than using strictly software RAID where no card is needed at all. From the description of your system, however, this wouldn't appear to be a problem. I'll opt out of the conversation at this point because your proposed setup is different enough from mine that I can't really helpfully comment on it. As I mentioned (and I believe even tried), the partial source code from Promise for the FastTrak doesn't compile (or at least isn't written to compile) for the 2.6 kernel. If the drivers you know of are slow, maybe Paolo is right and you should go with either strictly a hardware RAID controller or strictly software RAID given that you have a slick system. As for the boot loader issue, I'm not sure how a large BIOS is a solution unless you can get your boot loader to use your BIOS which I've never heard of. Unless you are using a true hardware controller, I'm not sure where/how your boot loader will be read with no other disks other than the RAID 0'ed disks.
