Re: What are you working on?

highflyer - we went through a CVM re-IP'ing because of a VLAN change.  It is not pretty by any way you do it.  I will say that we basically re-wrote supports document on how to do it properly.  So if you contact them they should be able to help you now.  If not, send me a message and I'll see if we can help.

Re: What are you working on?

My problem

While working on changing IP's my zk_server_config_file got a line added to it.

 

if you have 4 nodes, you should have three "zk lines" in the file.

so,

my file had

 # Version 10

10.0.0.1 zk1 # DON'T TOUCH THIS LINE

10.0.0.2 zk2 # DON'T TOUCH THIS LINE

10.0.0.3 zk3 # DON'T TOUCH THIS LINE

-------

after the ip change,

 

# Version 10

192.168.0.1 zk1 # DON'T TOUCH THIS LINE

192.168.0.2 zk2 # DON'T TOUCH THIS LINE

192.168.0.3 zk3 # DON'T TOUCH THIS LINE

192.168.0.4 zk4 # DON'T TOUCH THIS LINE

 

when I did a svmips

================192.168.0.1===============

2================192.168.0.2===============

3================192.168.0.3===============

3================10.0.0.4==================

Can't find a path to this node.

 

Once I,with Dell and Nutanix's help, changed the file in vi and rebooted the cvm....the cluster worked, and stargate is not down.

Hi Aleksei,

 

We have find the issue with de CRC errors and the host time-outs in ESXi 6.0. The CRC errors came from an old ESXi 4.1 cluster. That cluster is now completely destroyed Smiley Happy

The time-out issue was interesting! I seems like that our NVidia GRID GPU driver had some strange issues on ESXi 6.0. You saw in the log that the hostd was crashing trough the gpu driver. After a driver update of NVidia, the issues were gone.

 

In order to identify if GPU driver was causing the hostd crash, we need to extract the hostd zdump and then validate the backtrace:

 

portion of coredump backtrace:

Therefore I had to update the driver for the Nvidia G1 grid adapter as per VMware HCL

Also updated the ESXi host to the latest version 6.0U2 or Patch 03.

Re: What are you working on?

I am really having issues getting a working itteration of Remote Site replication working. Apparently there is a known issue with De-Dupe and replication in which replication performance is seriously hampered. Anxiously waiting for Astrix release to address this!

Re: What are you working on?

I'm working on migrating our existing workload from VMware to AHV.  The migration process is actually pretty painless, and with the exception of a couple of 'missing features', I think it's going to work out great!

I trying to setup a lab environment where I can implement and research more about the working off the technology.
