Yes, version 1 superblock support is in 2.6.13. You need the latest mdadm as well. > 2) Does the version 1 you refer to have to do with pre-2.6 RAID support? No. 2.4 kernels do not understand version 1 superblocks. They only support 0.90 superblocks (which is what you've got). > 3) My existing RAID was original set up under 2.4.18 on PPC, but I'm > running 2.6.11 now and it works fine... for now.

You'll have to re-create the array using the version 1 superblock format. The existing 0.90 superblocks will continue to be used until you've done that. -- Paul
