Home Lab - Odd Issue

DustinB3403

I've just downloaded the ISO from Xen's site, and did an MD5 check. Will build installation media and test tonight.

I'll also check to see if there is an available SATA port on the server.

Maybe get that cryptic message before you do anything else. Maybe we can solve the issue with the USB stick that isn't working right now.

Dashrender

I was wondering if the original USB stick might have just gone bad - but that wouldn't explain a bad password prompt, other than bad install as Coliver said.

Are you sure you're reinstalls aren't writting to the RAID instead of the USB drive?

DustinB3403

I'll collect all of the information tonight before proceeding with yet another install.

and @Dashrender I'm positive it's not installing the to RAID, but to the USB drive, but thanks for checking.

DustinB3403

Well something happened to the USB drive that was throwing the error.

At power up the system couldn't even find the drive to boot from.

I've reformatted the usb disk, and am installing to yet another one. I'll keep you all informed.

DustinB3403

Format to FAT32 and install seems to have corrected the issue.

OK so it would appear, that the RAID is orphaned from the Host OS, which makes perfect sense.

How can I go about deleting the orphaned storage, or just formatting the entire raid from within Xen?

You should be able to attach it again.

Any recommendations as to how, reading everything from online is not only vague, but often misleading

What does...

cat /proc/mdstat

tell you?

DustinB3403

When I try to recreate the filesystem using

pvcreate /dev/cciss/c0d0p1
 Can't open /dev/cciss/c0d0p1 exclusively.  Mounted filesystem?

That is what I receive.

DustinB3403

Attempting to perform the below:

# xe sr-create content-type=user type=ext device-config:device=/dev/cciss/c0d0p1 shared=false name-label="Local Storage"
The SR operation cannot be performed because a device underlying the SR is in use by the host.

Wait, do you have hardware RAID or software RAID?

Performing a fdisk -l results in:

# fdisk -l

That looks like an HP SmartArray controller.

You're running a lot of commands but not answering any questions

DustinB3403

It is an HP Smart Array, in a DL360 G5

Ah, okay. So that makes this a lot easier.

scottalanmiller

What do these commands say...

df -h

and

lvs
