Is mirroring supported on HighPoint 374's? I've defined two arrays for use in a multiboot system, one RAID0 and one RAID1. The 4 disks are attached as master drives on each channel of a HPT374. The HPT374 is integrated into an Epox 4PCA3+ mobo. Only the striped array is found by the ATARAID driver. I'm using a vanilla kernel 2.4.23-pre9. I've read all the docs I could find. The HOWTO mentions that only striping is supported. But that document is 30 months old.. Any help appreciated!
