XenServer 7 install to Dell R730 OBR10 15TB

@FATeknollogee I'm not certain, I've never presented more than a single disk to be used for the local storage.

If it create a single array across of the disks then it's doing some sort of RAID setup. Which would be bad, since you generally want your array managed by the controller

DustinB3403

Unless of course you're using software raid.

But this was previously setup inside of XS, not during installation. (there is a guide around here somewhere with software raid and XS 6.5)

FATeknollogee

That message seems to imply that XS would create some type of "span" across the 4 disks I selected.

I assume some sort of RAID setup (span is just a non-scary word for it)

BRRABill

I think it just spans it. No RAID.

So the individual 8TB drives are all listed as available targets, but selecting the thin provisioning seems to do nothing.

It still configures it as LVM, and thick.

For testing, go ahead and follow through with the process, then once the install is complete run
 xe sr-list uuid=<any 8tb uuid> params=all

Ran that cmd as root: result - "No such file or directory"

DustinB3403

@FATeknollogee You put in a proper SR uuid, correct?

FATeknollogee

@DustinB3403 My bad, I forgot to enter the UUID.

You don't have remote access (or out of band access) to the host?

You can do this directly via XC and the console connection.

FATeknollogee

THat's exactly where I am, in XC, console tab

FATeknollogee

Is this the right cmd to find UUID?

Good, just making sure you weren't walking to the server...

FATeknollogee

@DustinB3403 Haha, no prob., thx for the reminder!

DustinB3403

@FATeknollogee yeah.

Start here though

 cat /proc/partitions

Also in XC do you see local storage under this host, or no?

FATeknollogee

No local storage

Ok so it didn't create any storage for you at all to use, meaning you have to manually create an SR. Follow the guide I posted just above.

FATeknollogee

Ok, let me follow the guide.
I'll report back in a few

DustinB3403

Your mileage may vary with that guide, since you have many drives presented to XS.

Also wouldn't it be the smarter choice to go with EXT4 over EXT3?

EXT4 has some oddities that made some people (XenServer) not trust it completely. I'd say XFS would've been a better choice at the time, and brtfs should be the future.

Getting an error msg
"The SR operation cannot be performed because a device underlying the SR is in use by the host."
