Hi,
is anyone using flashcache vith openvz? If so, which version and with
which kernel? Versions lower than 3 do not compile against the latest
el6 kernel and version 3.11 and the latest git oopses in
flashcache_md_write_kickoff with a null pointer.
I see provisions to detect ovz kernel source

Hi all!
I thought it's really not good idea because technology like ssd
caching should be tested _thoroughly_ before production use. But you
could try it with simfs but beware of ploop because it's really not
an standard ext4 with custom caches and unexpected behaviour in some
cases.

I am actually planning on using it only on test systems where i have
commodity SATA disks that are getting a bit overwhelmed. I hope to get
better value from a SATA+SSD combination that I would with SAS disks and
the appropriate controllers and fancy RAID levels that cost 3 times
more at least.

I know about the recent change in UB limits default settings in vzctl. I
haven't implemented the same logic into bossonvz yet because
I have had some problems with the mentioned change in vzctl on some of my

I think at some point Openvz.org should provide trusted builds like
docker is doing.
Ok, I'll bite. What is a Docker Trusted Build? Whatever those are, I'm sure
the OpenVZ official OS Templates are the equivalent.
I knew about few incidents with ___FULL___ data loss from customers of
flashcache. Beware of it in production.
If you want speed you can try ZFS with l2arc/zvol cache because it's
native solution.

We are using this for only cashing reads (mode thru), not writes.
(offtopic) We can not use ZFS. Unfortunately, NAS with something like
Nexenta is to expensive for us.
Anyway, we are doing completely migrate to SSD. It's just cheaper.

From what I've gathered from a few presentations, ZFS on Linux
(http://zfsonlinux.org/) is as stable but more performant than it is on the
OpenSolaris
I know about this project, but what about stability/compatibility ZFS on
Linux with OpenVZ kernel? Has anyone ever tested it?
Also, with ext4 I can always at any [our] datacenter boot to rescue mode
and, for example, move data to another/new server. I have no idea how to
get ZFS data if something
This is to announce that RHEL5 based OpenVZ kernel branch will reach
End Of Life in October, 2014, and will no longer be supported thereafter.
There is no guarantee for any RHEL5 kernel updates after the given date,
so we urge everyone to migrate their systems to RHEL6-based kernels.

Hello!
Yep, Read cache is nice and safe solution but not write cache :)
No, we do not use ZFS in production yet. We done only very specific
tests like this: https://github.com/zfsonlinux/zfs/issues/2458 But you
can do some performance tests and share :)
