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 :)

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.
If you exper
I read
http://www.stableit.ru/2014/07/using-zfs-with-openvz-openvzfs.html . Do
you use it in production? Can you share speed tests or some other
experience with zfs and openvz?

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

We are using this for only cashing reads (mode "thru"), not writes.

Nexenta is to expensive for us.
Anyway, we are doing completely migrate to SSD. It's just cheaper.

If you want speed you can try ZFS with l2arc/zvol cache because it's
native solution.

We are using latest flashcache 2.* with 2.6.32-042stab083.2 in
production for a long time. Planning to migrate 3.0 with latest 090.5
but did not tried yet.

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 know about the recent change in UB limits default settings in vzctl. I

I have had some problems with the mentioned change in vzctl on some of my

I am actually planning on using it only on test systems where i have

better value from a SATA+SSD combination that I would with SAS disks and

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.

Eh, it looks like a kernel update kicked in while I was testing, so I
was loading a debug kernel 2.6.32-042s
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 i

Hi,
I have a host node that only works with kernels up to and including
2.6.32-042stab084.26. Any kernel higher than that and the host reboots
during vzctl start after "The container has been mounted" message. There
is no oops, no logs (netconsole is configured and running), no crash
dump, nothin

I guess many people are still waiting for an answer from the OpenVZ
