But finally I had to "give up" the Data I had on the old md1.The resizing basically worked fine (although I didn't do it completely as Piete suggested), In case somebody is interested...: 1. unmount /dev/md1 2. raidstop /dev/md1 3. Resize Partition (I used Partition Magic anyway...) 4. Boot, put down the location of the smaller new partition 5. Run fdisk and delete all partitions except those that you didn't touch (in my case sdx1/2, sdx2 is running md0 with everything on.) 6. Reboot, create Partitions exactly like in 4., mark them as 83. 7. Reboot, mkraid -f /dev/mdx (why doesn't it work, if I don't use the -f flag the first time when running mkraid? This was the trick I was looking for in the archives. If mkraid aborts without the -f flag, I have to start all over at 5.). 8. Mark Partitions as fd At this point I had to deal with some (for me) interesting thing: After I had created md1 everything seemed nice. The old data were still on it, despite step 5. When I rebooted after 8., md1 was not yet put back into fstab, so it didn't get mounted, but the array built correctly and I could mount it manually. I put it again as /home into fstab. Now fsck complained during reboot that SB would be out of sync. Couldn't repair it with efs2ck. The other arrays (md2 and md3) went smoothly with no complaints. I had run mke2fs /dev/md2/3 on them before, so the SB and PArtition table were rewritten. After I did the same thing on md1 it worked again, I used my backup of the data, so the server is up again :-))) So it worked, except that I couldn't keeep the data when resizing, had to use the backup....
