As I stated before, to my best knowledge (which is a bit dated) it is not possible to set up a decent md configuration that supports booting from just one of the two disks, replacing one of the two disks while running or rebuilding the array while still running production. << Hmmm. . . I'm using a: 01:00.0 RAID bus controller: Promise Technology, Inc. 20268R (rev 02) with PROMISE FastTrak Series Linux Driver Version 1.02.0.25 Adapter1 - FastTrak LP/TX2/TX4, IRQ(10) Array - Array[1] : 1X2 Mirror (OK-Gigabyte Boundary) Drive - 1: ST340016A Pri/Master Array[1] 40020MB BASE(0xdc00) BM(0xd400) UDMA5 3: ST340016A Sec/Master Array[1] 40020MB BASE(0xd800) BM(0xd408) UDMA5 SwapBox - 1 : SuperSwapBox - RPM(7941) TmpC(26°C) TmpF(79°F) Vcc(5.1V) V12(11.6V) 3 : SuperSwapBox - RPM( 0) TmpC(29°C) TmpF(85°F) Vcc(5.1V) V12(11.7V) and it does support those functions. I've written up the build process and configuration at: http://www.lesbell.com.au/Home.nsf/b8ec57204f60dfcb4a2568c60014ed0f/cc0e36c80bf652c7ca256d33001d5c83?OpenDocument My primary concern was the lack of support from Promise for kernels other than those on the Red Hat CD's, but I found they have a package which is a combination of proprietary object code and a source wrapper which can be built for any kernel. I initially set it up on a RH 9 system, but I moved it into our RH 7.3 file server, and I've had reports from another user who has it on RH 7.3 and has even built kernel RPM's including support for the Promise controller. I have mixed feelings about this, though. I was very disappointed with Promise's apathetic attitude and lack of proper support, to the extent ot publicly recommending against using their products. But with the driver problems now sorted out, the controller and its hot-swap boxes work well enough to meet my needs and are reasonable value for money. Sigh. . .
