The goal is to have userspace entirely backward compatible (well, to the
last incompatible device format chang
I'm rebuilding now the 3.16.6 version from fedora for el6 (I had to
make some small modification: remove perl-carp dependency and some
compiler flag). And it's for el6, so we have only elrepo with a newer
kernel.
Is it safe to install the kernel without recompiling it first for the
new platform?
When you say "el6" you mean "el7" right? The last kernel for el7 is
3.10.x
But Redhat lie a little with kernel version numbers. They say you have a
3.10 kernel, but I think they backport a lot from newers kernels.
Probably the btrfs of redhat el7 is not really a btrfs from 3.10, maybe
is btr

If you've formatted with features in common between 3.10 and 3.17, I don't
think you need to do this.

More concisely: Don't use 3.10 BTRFS for data you value. There is a

Don't bother reformatting (yet). The on-disk layout is stable between
the releases. It should run fine and all the

I went back from 3.17.0 to 3.16.3 when 3.17 acted flaky, and since then
gone up to 3.16.5 with nice results. 3.17.2 is, I think, expect
Thank you for your answer.

Can I downgrade the kernel from 3.17.1 to latest 3.10 if I have a

I mean, is there something that could go wrong with the fs if suddenly
I use an older kernel?
I want to downgrade because last night we had some 1200 oops's in 1
hour on the 3.17 kernel
