Hi guys, looking for a little bit of assistance with Ubuntu Server 6.06 LTS. What happened is we had an issue a little while back that required us to restore from a backup that we created while making changes. When we restored from backup the server wouldn't boot. Before, it was booting off of md0 but after imaging, the only HD that was available was sda so I had to make changes to mount points in order to reflect the device changes. Now we would like to re-establish the redundant array. The only issue is that a reload of Ubuntu and reconfigure of ISPconfig is probably out of the picture. What I am wondering is: is there any way to create some redundancy without having to reload the whole thing. Any help or suggestions would be appreciated. Thanks.
This page shows how you can rebuild a RAID array (software RAID1): http://www.howtoforge.com/how-to-se...ystem-incl-grub-configuration-debian-lenny-p4
Thanks for your reply falko. I read through all the information on that page, and it all seems to refer to only using md devices. Well, after restoration, my system has managed to lose all md devices and now only has one sda device. Just one question, if I were to run mdadm and create a RAID 1 array with sda and sdb by running (roughly) "mdadm --create /dev/md0 /dev/sda /dev/sdb" (i know it's incorrect syntax), but would that wipe out the data on the drive?
The guide http://www.howtoforge.com/how-to-se...g-system-incl-grub-configuration-debian-lenny shows how to set up software RAID1 on a running system. I guess it should work for your situation as well.
