Who has succesfully implemented Software RAID One with Red Hat 9?

Our specs: SuperMicro P4SPA+ Intel 865G chipset with ICH5, two 80GB Maxtor 7200RPM drives each on an IDE channel as Master. 1GB TwinMOS DDR400, P4-2.4C.

We were able to implement it. the problem is when we simulated a drive failure with the Secondary Master (pulled the plug on one of the Maxtor ATA/100 drives (of course while the system was turned off...)). The system worked fine and booted up on the Primary Master.

But, wen we put the Secondary Master drive back online, the image wasn't reconstructed and during boot up the message saying the filesystem was in "degraded mode" came up, i.e. mirroring wasn't working on the Secondary Master, i.e. failed RAID 1 implementation.

Any ideas as to whether our experiment was done correctly, or suggestions on things we should consider with such a setup when configuring RAID 1.

does anyone have some general experience with RAID 1 and linux?

Is RAID 1 supposed to automatically reconstruct an image when a failed drive comes back online or does one have to manually fix the image on the mirror drive and does linux have a way of doing this?

Thanks!

Yes, there is a nice SW RAID 1 howto for SoL - Server optimized Linux (http://www.sol-linux.com). I think you can use it for other distros also: http://www.sol-linux.com/Content/SoL/Documentation/sw-raid-install
Linux runs perfect with a SW RAID 1!

Did you have a bootloader manually installed on second harddrive since raid will most likely not mirror MBR
