Hi All, Thanks for everyone who helped me get my md1 data volume brought up correctly. Now I have another issue. I've rebuilt my host OS using RedHat 7.3, and I loaded it on RAID1 also. I built my data volume as md1 so that I could load the OS on md0, but I forgot about swap. Now I have md0 as /, md1 as swap, and another md1 data volume that won't activate since there is already an md1 in use as swap. Can anyone help me get my data volume brought up as md2? I have it in the raidtab as md2, but during boot it reads the superblock and knows it's md1, but won't bring it up since there's already an md1. I've gone back to the old OS disk, so I don't have logs handy, but if they're critical it won't be a problem to post them. I looked byt coulnd't find any pointer in the FAQ or Howto's... I know I could probably turn swap off, so that the data volume activates correctly, but I'm considering putting software RAID1 onto production servers, and now that I've found this issue, I really feel I need to understand how to manage it rather than work around it.
