See description of dmraid(8). Various metadata formats are supported (dmraid -l). Such vendord specific metadata typically sits at the end of each componet device in a RAID set and is vendor specific. If you are interested in details, look at the .h files below lib/format/ in the dmraid source tree. > The DMRAID man page sadly don't say anything about it how DMRAID works > and google finds a lot - but not what I'm exactly looking for .... > So i try it with this E-Mail ;) > > The Problem is, with the Intel P35 system and Linux my raidarray get > broken. And i don't know if DMRAID writes anything on the disks? Not yet. Enhancements to so in order to eg. replace a broken mirror member, are in the works. > All partitions are read-only mounted - or even not mounted at all - > still the raid get corrupted. > > With the nForce Chipsets for AMD CPUs dmraid always worked perfectly > (except the bug with an old DMRaid Version, but after compiling DMRaid > 1.0-RC13 everything just run fine) but with the Intel Chipset i even > can't say what exactly is the problem ... Might be a flaw in the isw metadata format handler.
