Bcache is hanging for me. When this first started occurring, I upgraded
from 3.10.9 to 3.10.19, hoping that it was fixed recently. At that time,
when I rebooted the machine everything returned to normal. However, the
machine hung up again within 24 hours.
I have two bcache devices with different backing devices, but with shared
cache. The backing devices are LVM logical volumes on top of an RAID1
software raid device (/dev/md2). The filesystem is ext4.

Off-topic, sorry, but if I understand you your layering is:
disks - mdraid - lvm - bcache - filesystem?
So you created an lv which is the backing device for bcache?
I've been looking at using bcache, but I was planning on switching the
ordering and putting bcache on top of the mdraid, then creating a pv for lvm
on the bcache device:
disks - mdraid - bcache - lvm - filesystem
Out of curiosity, I was wondering why you layered the other way.
Thanks.

Laziness, mostly. The RAID1 array is a PV that houses filesystems we'd
rather thot lose. The development databases are not so critical - we
rebuild them at least once a week anyway. The use of LVs was a quick
and easy way to test various caching implementations without increasing
the risk of data loss or corruption in the rest of the system.
If you want to provide a block cache for all of your logical volumes,
it would make much more sense to put LVM on top of bcache rather than
the other way around.

As I start to use more LVM based RAID, and with it fault allocation
policy's, logically it makes more sense to setup individual volumes as
backing stores instead of PV's. That way you always know your caching
the volumes you want no matter what PV device(s) they are sitting on.
That's really one of the great things about this. You can pick what
target you use as a backing store depending on your performance and
management needs. There is no one right way to do this.

Ah, okay, I get it; you had a pre-existing PV with production stuff on it
you didn't want to lose and were just testing out bcache, makes sense.
I haven't seen any responses to your hang report though :(, while obviously
there's no expectation of support, it's always nice if you're going to drop
something into production to have a forum where the experts give you a hand
when things blow chunks.

I looked at LVM raid once a while ago, it didn't really seem quite there
yet. I haven't checked recently, do you consider it a better choice than
classic md raid now? It would be one less layer in the stack, but mdraid has
been pretty bulletproof for me for quite some time and I'd be hesitant to
switch.

I would say it is going to be a better choice for use cases that are
more dynamic in nature. By that I mean where you may have a larger
number of smaller volumes that may have different needs for redundancy
and/or where you may be adding or removing physical devices often.
LVM RAID, not to be confused with LVM mirroring or striping, gives you
more flexibility in extent placement than what you have if you use MD
RAID. From what I understand the LVM RAID code comes directly from the
MD RAID code so it should be just as reliable as MD but give you more
volume level flexibility. There is obviously some serious performance
constraints that can come up if you mix RAID types on the same set of
physical disks but this is one place where bcache can come in and help.
MD RAID will still be the option of choice for me in cases where I have
a single large volume that will span multiple PV's such as a multi
terabyte media repository. Although since overall performance is not
terribly important for me there it may make more sense to just use LVM
RAID to keep it all in the same layer.
There are lots of good options that are becoming more viable now that we
have a real in kernel caching device to mask out allot of previous
performance concerns.

Ah, that's true; using raid at the lvm layer allows you to selectively
choose redundancy as opposed to dropping the entire pv on top of an mdraid.

Continuing to veer off-topic ;), what kernel version are you currently using
with bcache? I was originally thinking of going 3.10LTS, but ended up
installing 3.11 based on the mailing list traffic.

Not sure I understood that passage...
But in any event I'm working on a script I'm calling "md-3par" which will
create a number of chunklets (aka LV) from a set of PV (contained
naturally in a single VG) onto which to assemble a MD array of chosen
geometry and redundancy level. Of course one can then additionally layer
LVM, bcache, or (b)tier as desired. LVM is just a replacement for the
archaic and inflexible partition table, IMO. Granted snapshots and
thin-provisioning are nice to have.
I am disappointed that LVM is trying to expand into MD's territory. It's
bad enough they had the LVM 'mirror' (IMO a sad effort, pitifully slow,
and given it's unability to handle missing mirror members very much not
useful) and an interleaved 'striping'. Simple concat/extension of course
makes sense but the One True Faith of *nix is one simple tool to do one
job and ONLY that job to the best possible. If they want to pretend to be
ZFS-lite then just do ZFS already but keep it out of LVM. </rant>

If you take two physical disks, use mdraid, and then create a single pv
on top, every lv is redundant. If you take two physical disks, make two
separate pv's, you can either have a non-redundant lv, or use lvm raid
and have a redundant lv, and you can mix and match as you wish. This is
based on my understanding of lvm raid, which is not guaranteed correct
;), and as such should be taken as an opinion only :).

Actually that is probably veering back on topic :)
At the moment I am using Fedora 20 Beta's version of 3.11.8. I don't
yet have enough time with it to say how useful/stable it is. I try to
stick with something that has a better chance of making it into an
enterprise distro as that is my main focus.

Well, for the list maybe, but not for the thread, which has still not seen
any debugging/troubleshooting recommendations for the bcache hang originally
reported.

I generally run Gentoo unless there is a proprietary commercial application
involved, in which case we use RHEL. I can't see this being backported to
RHEL6, but possibly it might show up in RHEL7. I guess there's no firm
release date on that yet, but scuttlebutt has it that they will be using
kernel 3.11 (although I don't think that's intended to be an upstream LTS
kernel), which matches the current development fedora version...

I would say there is exactly zero hope of anything exciting coming onto
RHEL6 at this point. My hope is that bcache will at least be a "tech

hope they give us some more solid direction soon on what RHEL7 should
look like.
