I was trying to upgrade my OVM Server environment from *3.0.2* to *3.1.1* using the CD. I got the following error message after choosing the Upgrade option: Oracle VM server 3.0.2 (cciss/c0d0p2). The other option was to Reinstall System.
+"Error mounting device sda2 as /:+
+Device or resource busy+
+This most likely means this+
+partition hast not been formatted.+
+Press OK to reboot your system."+
My hardware is a HP BL465c G7 server, which is certified by Oracle to run the OVM 3.1.
Any advice that can help me find the way to upgrade my servers?
Thanks in advance,
I tried "yum update -y" and after reboot I encountered a kernel panic after the following message: switchroot: mount failed: No such file or directory.
So I got to reinstall ovm 3.0.3 from scratch.
Maybe the hard disk drivers in 3.1.1 kernel version (uek2) are not compatible with my server disks.
If someone has an accurate explanation to this issue, could be helpfull.
