XenServer installation SR issue

AdamF

Does it matter that I installed XS on the actual RAID 10 array that I want to use for storage?

No, thats when I get the error in the original post. "Logical Volume mount/activate error."

OIC. Missed that on my initial read.

No, that shouldn't be an issue. Have you verified that all firmware is up to date?

Check out this article where they describe a similar issue and list their solution.

@Danp I dont even see my disks in XC...

Danp

You would need to SSH into the box or use the console tab within XC.

@Danp Following that guide.... " A PBD already exists connecting the SR to the host"

Danp

@fuznutz04 That was for the xe pbd-create? Did you try performing the xe pbd-plug?

AdamF

@Danp yes, also an error. I just stepped away from my desk so don't remember what it was at the moment

Danp

@fuznutz04 Details are important.

If there's nothing meaningful stored on the array, you may be better off to just blow it away and start over from scratch.

AdamF

@Danp I did that.. Twice already. Brand new installations

@fuznutz04 IDK. Seems odd that this has occurred multiple times. Found this forum post that you may want to review.

what is the output of vgs, lvs, pvs from the console?
Seems like either your lvm layer is bad, or the actual raid array is bad.
Have you tried to unmount this and then runs fsck?

Really weird that the local sr wasn't auto created for after install. It is like the first thing that happens when you connect to XS with XC.
Since it is not working you could just reinstall and try again, there shouldn't be an thing on it at this point.

I think he said he did that a few times already.

I wonder if it is indeed something with the array?

BRRABill

XS installs are usually pretty pain-free.

I ask this for understanding sake.

When you install XS on a hardware RAID Array, how does XS see the remaining disk? Does it see it as a completely different disk from the one XS is installed on? or does it realize it's just empty space and create an additional partition to whatever size you dictate?

Since it is a DELL H700 (I have the H710) it's just all one big array. No slicing it up from the hardware level.

Would have made things so much easier.

On my xs 6.5 install (which originally was 6.0 I think way before I started here) xs is installed on sda which is the local disk array. The partitions for xs are sda1 and sda2 while sda3 is the local sr. I didn't originally set this up but I would think that you just give XS a whole array, then let it take what it wants for itself, it then gives you the rest to use as local SR.

And yes, I've reinstalled twice. The second time, I completely destroyed the RAID array, and created a new one. Then ran a Fast Init on it and install XS. That's all I've done to get to the point of error.

I think you may need to use a different uuid in your xe pbd-plug command
Here is a reference article
http://support.citrix.com/article/CTX121896

This one in your case(I think):
xe pbd-plug uuid=0bff8e3b-dd7c-c3c4-3125-22569f5bbd77
