Disk /dev/sdb doesn't contain a valid partition table

I’ve installed Oracle Linux 5 as a guess OS on VirtualBox. I’ve added a new disk to the virtual machine.

Code:
[root@11gr2-secondary ~]# fdisk -l

Disk /dev/sda: 32.2 GB, 32212254720 bytes
255 heads, 63 sectors/track, 3916 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 32 257008+ 83 Linux
/dev/sda2 33 1337 10482412+ 83 Linux
/dev/sda3 1338 1990 5245222+ 83 Linux
/dev/sda4 1991 3916 15470595 5 Extended
/dev/sda5 1991 2643 5245191 83 Linux
/dev/sda6 2644 3165 4192933+ 82 Linux swap / Solaris
/dev/sda7 3166 3687 4192933+ 83 Linux

Disk /dev/sdb: 4294 MB, 4294967296 bytes
255 heads, 63 sectors/track, 522 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

Before the above I’ve done a mkfs on the new virtual disk, i.e.

Code:

[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sd
sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sdb
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sd
sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sdb
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sd
sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sdb
[root@11gr2-secondary ~]# mkfs -t ext3 /dev/sdb
mke2fs 1.39 (29-May-2006)
/dev/sdb is entire device, not just one partition!

OVM Server for SPARC … Need Your Help Guys !

Leave a comment

By Mack1982

>* I have two SPARC T4-2 servers:
– Oracle Solaris 11.1 Installed.
– Oracle VM Server for SPARC 3.0 software Installed.
– Shared LUN provisioned to both servers from Clariion CX4 storage box (shared LUN to be used for the Live Migration of the VMs).
– Oracle VM Agent 3.2.1 for SPARC installed.

* Oracle Linux and Oracle VM Manager 3.2.1 installed on Oracle X6220 server.
– the T4-2 SPARC servers has been discovered and added to a pool using the OVM Manager.

How can i configure the shared LUN that was provisioned from the CX4 storage box to the OVM servers to be as the VMs repo./location and use the Live Migration Feature?
I tried to scan/discover the local disks attached to OVM servers from the Manager GUI but it didn’t drop any thing !

Please advice about the proper configuration apart from using NFS …… if it is not possible to use the SAN …. how we can configure the NFS so !

Need Advise on various Linux Install

Leave a comment

By newbie_01

Hi all,

First off, Happy New Year.

Just recently bought a Gateway/Acer 16GB laptop that comes pre-installed with Windows8 and 500GB drive. I also bought a 1TB external drive.

I need to install several Linux Distros on it, Ubuntu, CentOS, Oracle Linux, Fedora, SuSE, that’s just for starter. This is because I have several customers that uses different distros and I need to install Oracle on them. Besides the Linux distros, I also need Oracle on Windows running :(-

Can anyone please advise if this is achievable? I’ve read several blogs of issues installing Windows8 and Linux’es. I am looking at re-partitioning the Windows 8 HD and create another partition there for the Linux Distros but a bit anxious whether that will break Windows 8.

Performance is not an issue at the moment. Will using the 1TB external hard drive be a better option? Can I create boot partitions for each distros on the external drive and then boot off the external drive? Does the boot partition need to be ext or they have to be FAT32?

I want to be able to explore this option first before going to using a VirtualBox on Windows8 as the last option.

Any advise/feedback will be much appreciated. Thanks in advance.
