Nope. Mine are openvz boxes on a single server. I can actually generate the same issues by hammering a clean server - no vm's with loads of random io. :-)

Sadly.. I have no 100% fix. Still searching.

Latest kernel is 2.6.32-10-pve I use this and a custome lsi megaraid driver for all mine.

Hello, I am basing my info from this page: http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5082327 May be wrong.. guess the easist way is the following on your server: lsmod |grep mega if you come back with something like: megaraid_sas 93022 2 Then it is...

Assuming you are talking IBM serveraid. To my knowledge this is yet another LSI megaraid reband. (please correct me if I am wrong) I two have had no problems until I overstressed the IO.. and suddenly the same issues occured again! Even with HCP! This leads me to believe that their is still...

My script (v1 nearly ready) is essentically a basic re-implimentation of vzdump So... hcpdump <all|vmid> it then creats a dump that can be restored using the regular proxmox tools. The biggest issues appear in my opinion to be related to LSI cards; using a sata drive. I have found loads of...

I am working on a script called hcpdump that should be stable. As soon as I have it working I will post it Rob

Hello, This article http://www.anchor.com.au/blog/2012/03/bugfixing-the-in-kernel-megaraid_sas-driver-from-crash-to-patch/ has some interesting debug and fix on the lsi problems. I have checked and the 'patch' they have is not yet included on the LSI supplied driver source. So guess it may...

Any chance you are using an LSI based raid card?

Hello, Silly question I am sure! vzdump of openvz containers basically does a tar of the container. Not a problem :-) But where in this tar file is the machines configuration file kept? e.g. My machine is is 102; and has the config file: /etc/vz/conf/102.conf on the host. vzdump creates...

My fix is to never ever ever use vz dump! I now use r1soft hcp to do manual snapshots. But would love a proper solution :) Sent from my iPhone using Tapatalk

I think you may be trying to snapshot a physical machines volgroup? I have never tried this. Try snapshot the volgroup for /var/lib/vz Sent from my iPhone using Tapatalk

What does the error log say? I would assume something in /var/log/messages Sent from my iPhone using Tapatalk

Have you run: hcp-setup --get-module ? And also installed your kernel headers? Sent from my iPhone using Tapatalk

Right... Case scenarios: These are difficult to debug - I aggree. If the issue does not occor on your machine - then how do you fix it! Here are some examples: http://www.redhat.com/archives/linux-lvm/2010-April/msg00035.html https://bugs.launchpad.net/ubuntu/+source/linux/+bug/605551...

I agree. It cannot replace LVM for all core functions. I personally have not experienced any issues with LVM using these sort of functions. The issues only occur when doing snapshot backups. That is why I have only suggested it for an option in the vzdump function :-) Rob

Why oh why does written text get miss-interpretted! I feel you have taken my comments as negative or critisisms - yet that is not what I have intended. I fully understand that the point is to make the software the best; and that you need to act as gate keepers to ensure the end product works -...

I totally get the point you guys may have in keeping to lvm - and reluctance to use alternative systems. Remember.... This is all about choice. No solution is a perfect fit. We all do things a bit differently. The beauty of open-source is that it provides the ability for alternative...

I agree. Most issues seem to source on Lsi cards. But strangely.. This not appear to cause problems with kernels pre 2.6.32. Redhats answer to the problem was - run an earlier kernel! Not really a solution. I agree about not providing a non gpl product in a gpl solution. You will note...

I can reproduce the lvm crash on my systems easily. Simply generate high io... Do a 'very long' backup. And the unmount the snapshot. The system goes into a state where all disk io stops. Only solution is a reboot. I am not saying hcp is better. And don't want to get into a flaming war...
