How do I mount this as a SR in XenServer 6.5
-
@travisdh1 not relevant at the moment (performing a clean install)

https://support.citrix.com/article/CTX121896
does this article assume the local disk to already have a partition on it?
-
My local SRs on 6.5 are over 2TB
lvm not ext though. -

-
Was already here when i started
My guess is after though. I would be able to say for sure if there was any documentation for our XS infrastructure when i started. There wasnt. -

@Dashrender said in How do I mount this as a SR in XenServer 6.5:
We know from Dustin's posts that XS is creating a sba3 for the remaining space that XS itself doesn't use. That space is created as EXT3. I don't know enough about Linux and partitions, can EXT3 support 14 TB?
Yes, that's small for a filesystem.
Not for ext3. Max supported size is 16 GB.

Well on 32bit systems, yeah. But we're not on those. 32TB on 64bit.

We are still talking about the system drive, right? At least a VG will come into play as you can't just use an entire PV in that case.

No that's total. https://access.redhat.com/solutions/1532
Even on 7 which is 64 bit only.

Mother [moderat]ing thing works this time!

That's a RHEL limitation. Not ext3.

Even in 2011 it was 32TB. You use 8192 block size instead of 4096.

Which is what XenServer is built on. So the same limitation applies.

@DustinB3403 type being LVM is important.

XS smiles, nods at @scottalanmiller and slinks back into the corner.

But I ran this guide before earlier today and had the same issues.
Except that I was installed directly to the OBR10, and still had no storage.

while going through these instructions
http://support.citrix.com/article/CTX121313He added the 14TB drive as LVM instead, where XS was creating a 14TB with EXT3. Not sure why this mattered, If time allowed, Dustin could have tried this command with EXT instead and tried to mount it. But time is of the essence so he only tried LVM.
