Oops! This was the wrong thread! Sorry. So, ignore the resize stuff and read the dd stuff.

"You must resize the partition now. The device that the partition on is now about 500Gb, but the partition is still 250Gb. If you're partition is ext2 or ext3, you can use resize2fs. A word of caution for you. I've used this utility many times, and it is necessary to do a e2fsck -f on the partition to be resized BOTH before and after. The program itself will require you to do it before. If you skip doing it after resize2fs completes, you will almost assuredly ruin your filesystem. I've skipped the fsck after the resize2fs myself 2-3 times, and it killed the filesystem every time.

This is just a read test. You can test all at the same time if you use different windows (xterms, or whatever).

What I had been trying to do was expand one of my ext3 volumes on top of the lvm, I had taken it offline and evms was proceeding with the expansion, but then the server locked up. Now, the reason I think this list might be the right spot is that whenever I boot up it hangs after detecting the arraying and beginning a sync. To troubleshoot I attempted to remove the md0 device and recreate it with mdadm. Upon doing this it hung immediately. Mdadm reported that the array still existed and that it would try to bring it online, at that point it just hung. I didn't get a kernel panic error or anything just a blank line. Are there any logs that I should send along to the list or if perhaps anyone has any ideas on what might have gone wrong/how to fix it?
