Can't create NSS pool with iManager

I have installed SLES 10 SP2 and OES2 SP1 (x86-64) onto a new sever with a new tree.

Everything seems to work fine but I can't create a NSS pool and volume in iManager, I get this error:

Error: The selected segment is not available. Select pool segments from free space on an unpartitioned device or an EVMS-managed device.



In Yast Partitioner I see I have a device (/dev/sda) that is 233GB in size.
On this I have a 22GB linux partition (/dev/sda1) and a 4GB swap partition (/dev/sda2).
This leaves me over 200GB for NSS volumes.

In iManager I have selected Pools from the Storage menu and then selected my server followed by New to create a new pool.
I then entered a name for the poolfollowed by the used size (mount on creation is ticked).
When I select Finish I get the error.

There's your problem. LVM is the default volume manager, whereas NSS
requires EVMS. The best solution is to use a completely separate hard
disk (or logical disk when using an array controller) for NSS. It's
possible to use it on the same device as your root partition, but it's
very difficult to configure and prone to breaking. Since this is a new
server I would look at blowing it away and using a separate device for
NSS.

Having done this many times I second this idea.

Creating the Partition, pool and volume is trivial if it is a second
physical drive/RAID array.

Re: Can't create NSS pool with iManager

I get the same error in an ESX environment...
Which had 7 separate virtual disks already, some of them NSS, and stored on a SAN.

However after adding three additional virtual disks that are on the SAN also I received the same error as above when attempting to create an NSS Pool.

I've tried with NSSMU and explored with EVMSGUI, to no avail.

Most advice about this error relates to using a separate disk for NSS, which is what we have (virtual one). Can anyone suggest why we have this issue, or is there a trick to setting up NSS on ESX server / SAN environment?

Cheers
Gordon

So you've got a different problem. Please start a new thread.
