I've had to add a disk to a VM (RHEL5) in VMWare due to space issues and at the same time, I've optimized the disks assigned to SCSI controllers, because some disks are for Oracle. It would have been 7 disks to one controller, however I split them up. One controller (LSI Logical Parallel) has three disks that pertain to the RHEL5 OS and the other controller (Paravirtual) now has four disks that pertain to Oracle, are assigned to it. Rebooted and seems ok. However when using the fdisk command a number of the partitions are showing the following:
[root@server etc]# fdisk -l | less Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc doesn't contain a valid partition table Disk /dev/sde doesn't contain a valid partition table Disk /dev/sdf doesn't contain a valid partition table Disk /dev/dm-0 doesn't contain a valid partition table Disk /dev/dm-1 doesn't contain a valid partition table Disk /dev/dm-2 doesn't contain a valid partition table Disk /dev/dm-3 doesn't contain a valid partition table Disk /dev/dm-4 doesn't contain a valid partition table Disk /dev/dm-5 doesn't contain a valid partition table /dev/sda2 14 6527 52323705 8e Linux LVM
So far the guest seems ok, and I have a snapshot to fall back on, however it bothers me to see this. Was wondering if anyone has come across this before when moving disks between SCSI controllers and what to make of it? thanks
