Building Out XenServer 6.5 with USB Boot and Software RAID 10

Yes, seems ok. Reboot and try to check the status of the array once again

Rebooted.

Array found, drives mounted.

DustinB3403

So now that we're back to working condition. We need an entry added to fstab to auto-mount the array.

  GNU nano 1.3.12             File: /etc/fstab                                  

LABEL=root-mhdhrpdq    /         ext3     defaults   1  1
/var/swap/swap.001          swap      swap   defaults   0  0
none        /dev/pts  devpts defaults   0  0
none        /dev/shm  tmpfs  defaults   0  0
none        /proc     proc   defaults   0  0
none        /sys      sysfs  defaults   0  0
none        /sys/fs/cgroup cgroup memory 0 0
/opt/xensource/packages/iso/XenCenter.iso   /var/xen/xc-install   iso9660   loo$
/mnt/raid10   /dev/md0  ext3  defaults 0  0

Does xencenter see the storage?

DustinB3403

Yes, the Local OBR10 is back on XenCenter.

Romo

@DustinB3403 Not so sure about the entry on fstab, I don't have the entry in my setup and xen properly automounts it

DustinB3403

@Romo It's outside of the norm for XenServer.

Even if it's benign.

XenServer by default, doesn't say "oh yeah go build an mdadm array" because it's not ideal if you can avoid it.

Yes indeed.

Looks good?

@anonymous besides just the two disk, yeah it looks alright.

Nothing wrong with RAID 1!

Alex Sage

Will this guide work with CentOS 7?

It likely would, but you'll have to test it to find out.

To do what with CentOS 7? Do you want to install CentOS to a USB stick? Or are you just looking for the MD RAID portion?

scottalanmiller

We need to make this guide again with XS7.

DustinB3403

Has anyone attempted this guide on XS7? Confirming what works and what doesn't.

Alex Sage

@DustinB3403 I'll try it tomorrow night.

@scottalanmiller Well, change of plans, I ordered 32GB more RAM and 2 New 64GB thumbdrives, which will be here Saturday. Will upgrade then and test
