Home Lab - Odd Issue

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.

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.

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

DustinB3403

df -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p1 4.0G 1.8G 2.0G 47% /
none 932M 20K 932M 1% /dev/shm
/opt/xensource/packages/iso/XenCenter.iso
56M 56M 0 100% /var/xen/xc-install

And

lvs
  No volume groups found

You appear to be booted into the RAID array. Your root filesystem is located there.

scottalanmiller

You are running from the RAID, as @Dashrender hypothesized, not from the USB stick.

DustinB3403

hrm... that's very odd....

DustinB3403

I performed the identical installation as I have previously, and the OS was installed to the USB drive.

Who knows what the storage looks like now that a new partition has been created over top of the filesystem that was there before.

DustinB3403

But it does make sense now

DustinB3403

I'm not concerned with the data on the RAID.

I just want it corrected. Installed to the USB drive, and running from said USB. While having the local RAID 10 array for VM storage.

DustinB3403

I'll be back, going to reinstall!

DustinB3403

Now performing the install yet again, I see the key difference with the installer.

The initial screen (for what ever reason) was only installing to the local spinning rust array, rather than the 8GB Drive.

I found a 16GB and restarted the installation, at which point it listed 2 devices to chose from to install Xen too.

Wow I wished I noticed that before hand lol

DustinB3403

And we are back in action!

Sweet!
