You should consult the libata documentation and see whether this chip is supported. Even if you want to use this kind of RAID, using a random binary driver downloaded from a non-Linux vendor is increasing your risk. You need to track down whether a driver for this is in the mainline kernel. I cannot copy the data off and rebuild new volumes for the data). I need to know if I can use these volumes in Linux as they are just now (i.e. I already have 3 Raid5 NTFS volumes which were created through Windows on the RAID enclosure I intend to use with this card. This can be a real-world data saver, too. In addition to the better chance of recovery it has more advantages such as not limiting you which drives you can smack into the array. On the other hand, Linux' md driver (real software raid) is one of the finest pieces of Linux software and gets your behind out of the wheelbarrow all the time. Forums are full of reports of recovery failing (read: wipe out the good drive left over when one drive fails in a raid-1) when a reboot happens during recovery or something similar. The recovery in case of an error is complicated enough for one dedicated RAID system, but in the case of these things you have them twice, once in the BIOS, once in the driver at runtime. It doesn't directly answer your question, but unless you want to run raid-0 I cannot recommend that you use any of that onboard SATA raid stuff. Reading up only gets you so far.there are plenty of incomplete guides that don't take into account what could go wrong when you're following them through. I'm just making very slow progress on my own and I'm worried that I might lose the data on the array if I keep blundering about. Memory Range: 0xfbff0000-0xfbff7fff (rw,non-prefetchable) Memory Range: 0xfbfffc00-0xfbfffc7f (rw,non-prefetchable) SubVendor: pci 0x1095 "Silicon Image, Inc." Model: "Silicon Image SiI 3124 PCI-X Serial ATA Controller"ĭevice: pci 0x3124 "SiI 3124 PCI-X Serial ATA Controller" I've installed the hwinfo package and looking at the output from hwinfo -storage it looks as though the system recognises the card: I've done quite a bit of research but I have yet to find definitive answers to the questions above.Ĭan anyone please answer the questions and/or point me in the direction of some sort of guide/tutorial to getting things working? I'd really appreciate it. Put simply I'm very confused with this whole situation. I've also found something called libATA () which looks like it has support for the Sil3124 in all distros of linux. The User Guide () has a section on using the RAID Manager on a Linux environment, but drivers () only seem to be available for a few distributions (not including Ubuntu). I've read some very confusing and conflicting information when it comes to the Sil3124 drivers and SATA RAID Manager software in Linux. If the above is true then read on, if it's not then stop here ) If I can get the card working properly in Ubuntu will I be able to use the existing volumes without losing any data? They were created using the SATA RAID Manager in a Windows environment (XP SP2). The first question (and most important) is that I have some existing volumes defined in the array with a lot of data on them. I have a few questions centering around using a Silicon Images Sil3124 based RAID controller with Ubuntu 8.10.
