This was fantastic help. This evening I went for it and got pretty far. Doing the RAID clone was a wonderful idea - the files copied in about an hour. I now have a booting system with both the 500GB drives in there in a RAID 1.
Just one last thing to do. During the RAID merge with the mismatched drive sizes, mdadm drew down my partition size on the 500GB drive to create a partition that matched the size of the Linux Raid partition on the 300GB drive. So, even though I have a working system, I still have to extend that booted partition to fill the remainder of the free space. That's for tomorrow - hopefully I'll use the right program and not have to go back to the start. Thanks to all who have tried to help, -- Dave Spencer, PageWeavers --- Original Message --- I also figured I'd mentioned that with a mirror it's even easier. I just did this to migrate from 2 250GB disks to 2 500GB disks. Something along the lines of: #1 Pull disk B, put it in a safe place in case this goes poorly. #2 Insert 500 GB disk B #3 partition disk b #4 hotraid add #5 install grub #6 wait for raid sync #7 shutdown, put 500 disk B in slot A and new 500GB disk in slot b #8 partition disk b #9 hotsync b #10 install grub #11 resize2fs and/or lvextend No need for partition magic, and most importantly if it goes poorly you have an original disk to use. Partition magic and friends often work, but I wouldn't want to try them without a backup. You have a backup... right? So there's potentially 3 things to change: 1) Software RAID 2) LVM (pvresize and/or lvextend) 3) Actual filesystem (resize2fs or friends) _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
