I am observing different behavior with Debian Lenny and “dmraid” in the following two scenarios. I have configured one logical volume in RAID-1 on embedded SATA controller on HP ProLiant DL320 G5 server.
1. Windows 2000 Advanced Server and Debian Lenny
a. Installed Windows 2000 on one half of the disk (36GB) and left the other half empty with no valid partition/file system
b. Booted the system with Lenny CD image and started the installation with “install dmraid=true” option
c. Debian installer recognized windows partition and let me choose the empty partition to install Debian
d. Lenny installation went fine. Both the OSes (Windows 2000 AS & Debian Lenny) boot fine
2. Created a fresh logical volume in Raid-1 on embedded SATA. No OS exists before starting Debian Lenny.
a. Booted the system with Lenny CD image and passed “install dmraid=true” option
b. Debian installer failed to recognize SATA RAID-1 volume. It instead presented two physical disks to choose.
c. I installed libdevmapper, dmsetup and dmraid SW components with “udpkg -i” command
d. Executed “dmraid –ay –vvvv –d”. But dmraid failed to execute and displayed the following:
dmraid: error while loading shared libraries: libdevmapper.so.1.02.1: cannot open shared object file: No such file or directory
e. “lsmod” does not list dmraid or devmapper modules. (In the first scenario, “lsmod” does list dmraid and devmapper modules.)
How do I install Debian in 2nd scenario? My reference to this installation is http://wiki.debian.org/DebianInstaller/SataRaid
Thanks for any help!
