[sles-beta] SLES12 beta3 question concerning XFS boot

Hi Matthias

Thank you very much

This is exactly what "dr google" showed me.

Superbe!

Yes of course, I joined this most welcome and very informative presentation.
I am looking at BtrFs on one of my test servers and I already replayed snapshots after applying zypper changes.
Works really perfect and in an amazing very fast way!
It is also already very well documented in book.sle.admin.pdf, chapter 4.

I would like to have a detailed look at all filesystems coming with SLES12, just to be able to know "what I am talking about" ;-D
Reason for this is, that some of our application architects like to have /opt for their special purposes (Weblogic, TC-Server ,etc.)
But when using BtrFS /opt should be a subvolume for snapshot purposes.

Best regards

Hello Urs and all,

this was and remains correct for SLE 11, as the grub1
bootloader does not successfully interacts with xfs
in all situations. For SLE 12, we have grub2 now, and
thus:

Yes, xfs is supported "everywhere" in SLE 12, including
/boot.

Our recommended filesystem for the OS is btrfs though,
as detailed in the presentation 3 weeks ago.
