nvm, I figured it out after my whole day :)<br>The BIOS was automatically updated and moved the OS drive down from the 1st boot drive to the last boot drive. sheesh, so simple!<br>Thanks anyways!<br><br><div class="gmail_quote">

Hello,<br><br>I have a GridEngine setup with 5 subnodes and two RAIDS attached. I backed up the OS drive - 120GB - to an external hard drive - 500GB - using ddrescue. The OS drive is partitioned as:<br>sda1 has the OS and is about 7 GB<br>
sda2 has /var and is about 4 GB<br>sda3 has swap and is about 1 GB<br><br>After backing up, there were 4KB of errors, but all at the end of the disk around 118GB. This used to be a partition back in the day, but I deleted it accidentally. I want to back up to this new larger disk b/c the original 120GB disk is discontinued. I boot from a live cd - SystemRescue CD - and run e2fsck -c -c -C 0 y on sda1 and sda2 on the backup drive, and it seems to finish fine. Then I replaced the OS drive with the backup drive, and it goes to boot, then Grub Loading Stage 1.5; Error 22.<br>
<br>Here's the important stuff from fstab:<br># This file is edited by fstab-sync - see 'man fstab-sync' for details<br>LABEL=/1 / ext3 defaults 1 1<br>none /dev/pts devpts gid=5,mode=620 0 0<br>

<br>I boot up from the live cd, and then tell it to search for bootloaders on the drives, and it finds one, and it goes through, and then throws errors b/c it is mounting the OS /sda1 drive and then trying to run fsck on it. I tried setting the error-check values to 0 for /1 and /var, but it is still trying to error check it.<br>
<br>My blkid says that sda1, sda2, and sda3 all have different UUIDs. sdc1, sdd1, and md0 all have the same UUID. md0 is a RAID1 comprised of sdc1 and sdd1. sdc and sdd are identical drives.<br><br>This used to happen, and I would just restart a couple of times, and it would sneak on past the error eventually, but to no avail this time. Does anyone have any ideas? Thank you so much!<br>
<br>And thank you to the dozen people who offered advice on the best backup option. After reading all of the replies and the links, I think I will prob go with the rsync-backup suggestion.<br><br>Mahalo,<br><font color="#888888">Jeff<br>
