Hello list. A few months ago I posted a help request concerning the creation of a RAID0 volume using OpenBSD 4.4. http://marc.info/?l=openbsd-misc&m=122796220028136&w=2
Shortly: i386 PC with 3 PATA disks. - a 60g Maxtor attached to motherboard's IDE controller (wd0) - two 160g Maxtor attached to a Promise FastTrak TX2 PCI controller (wd1 and wd2) - a single 320g RAID0 volume (sd0) created on the two 160g disks. A few days ago the controller became definitely unstable: I keep receiving error messages from both disks in the RAID and I can read the volume's content only a few megabytes at a time. It's not that important, otherwise I would have used better equipment in the first place, but I'd like to try and retrieve the disks' content as an exercise, just to see what could be done in a "real" environment. Since during boot the FastTrak's firmware shows the disks approx 2 times out of 3, I thinks I'm quickly loosing either the controller, or both the disks, or the whole thing. Supposing the disks are failing there is very little to do except by spending half my year wage to engage broken-disk-data-retrieval specialists. No way. I have a Guzzi Stelvio to buy. On the other hand, should the controller (which was a crappy piece of cheap stuff back in 2001 when I bought it) has died once and for all, I could try to replace it and restore the RAID0 volume. Since I don't have access to a spare PATA controller, I can either plug the disks into the motherboard's IDE controller or use two USB2 disk cases I already have. Is there any kind of command to issue in order to have the PC scanning the disks for the RAID volume (I'm thinking about Linux LVM's vgscan)? Any suggestions abou how to proceed with this? Once more, I don't really care about the data in the volume, it's just a matter of curiosity. And yes, I already bought a new SATA controller and two new 500g SATA disks in order to replace the crappy stuff :-). Thank you all, Manuel -- Hana wa sakuragi, hito wa bushi
