Hi All,
I'm using the VMware standalone converter tool (v5.5.2) to P2V a Dell 2950 running OEL 5.1 on a RAID-1 virtual disk. The disk controller is a Perc 6/i integrated according to the Dell OMSA.
-
The P2V seems to run without an issue, but when I boot the new VM, I get the dreaded kernel panic after:
Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root'
<snip>
Lots of general google hits on it, but nothing I've tried has helped. I presume I'm missing something from my rebuilt initrd, but I don't know what.
-
I have been successful at P2V'ing on similar hardware and OS, but the main difference is that it was a single disk configuration.
That makes me think the raid controller is fouling me up, but I'm not enough of a Linux guru yet to solve this issue.
-
Any ideas?
I'll also be happy to provide any more information to help troubleshoot this issue.
Thanks!
Mike Wood

Hello and welcome to LQ.

I don't have an exact answer but this question has been sitting so I'll offer some questions at least.

P2V apps do pretty good on a windows but linux may have some issues. What vmware is doing exactly I can't say. It may not convert any hardware other than network if that.

In any clone or conversion you have to take into account some of the underlying naming. One comes to mind that you ought to start with is the grub naming.

Can you boot to single user mode?

You will have to bone up on grub pretty fast I'd think.

You should be able to boot this system to a live iso of Oracle, RH, Centos or even Fedora to look into the now virtual hard drive.

While I agree that the original drive was mounted on a raid, there are only a few issues that separate a hardware raid drive versus a sata connected raid.

As to why a similar conversion worked and not this I can't say. How a muli drive raid on perc worked and not a single I can't guess.

Hi, and thanks for the response.
I discovered what the problem is/was.

On the physical server:
# fdisk -l

Disk /dev/sda: 146.1 GB, 146163105792 bytes
255 heads, 63 sectors/track, 17769 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 17769 142625070 8e Linux LVM

Using an lvm filter of:
filter = [ "r/sd[b-z].*/", "r/disk.*/", "a/.*/" ]



On the P2V:

# fdisk -l

Disk /dev/sda: 108 MB, 108134400 bytes
4 heads, 32 sectors/track, 1650 cylinders
Units = cylinders of 128 * 512 = 65536 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 2 1633 104448 83 Linux

Disk /dev/sdb: 171.7 GB, 171798691840 bytes
188 heads, 7 sectors/track, 254972 cylinders
Units = cylinders of 1316 * 512 = 673792 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 1 254973 167772096 8e Linux LVM


The /dev/sdb1 device is being filtered.
I adjusted the filter on the physical server and re-attempted the P2V.
It worked like a charm.

Outstanding!

Thanks for the update and solution.
