sysctl: permission denied on key 'vm.max_map_count' - OpenVZ Elasticsearch 0.90.9 compatibility issue #4978
Comments
Hey, can you please check, if the process started anyway? It should have been. The error is just a permission problem due to your VM, but should not prevent elasticsearch from starting usually. |
I've got the same issue, and on my VM it's not starting. |
can you add |
do you mean |
sorry for not being clear. You can do the following: Open

Then run Thanks a lot for helping! |
|
can you run |
Returns just header, i've tried |
Can you make sure elasticsearch does not run, and try this on the commandline (as root!):
and paste the output here? |
{0.90.8}: Initialization Failed ...

@empirik One last question: Did this message also occur in the log file at |
@spinscale I don't see this message in logs. |
Just for the record. Getting same error on startup in openvz, but elasticsearch runs without problems for now. A bit irritating as normaly a service start error means the service won't run. As opposed to a warning. |
I dont know openvz enough, but not setting this setting can also result in lucene exceptions and indexing problems, it is not only about performance here - I dont how openvz is handling this. Can you get us any insight here @derEremit? |
Got the same on openvz |
I see the same message on big index but after allocating more memmory elasticsearch starts at least :) Using OpenVZ too and elasticsearch 1.1.1. |
Got the same on OpenVZ and elasticsearch 1.2.0. |
Got the same on OpenVZ and elasticsearch 1.2.0 |
Basically openvz does not allow modifications of kernel parameters as these would affect the host and every other guest machine. |

Hi all, |
Hi all, Thanks to scamianbas for his tips, I tested this on proxmox 3.2-4, debian7-x64 template, works like a charm ! Thanks to the elasticsearch guys too for this great piece of software ;) |
FYI: fresh install of Unbuntu 12.4 with elastic search 1.3.1 over the top, following this Gist (easy way) for install https://gist.github.com/wingdspur/2026107 I get the error
when I do a ps check, I get ps p $(cat /var/run/elasticsearch.pid) and finally when doing "service elasticsearch status" it says it is running. So the error has a slightly different prefix (error: and not sysctl:) but as with other information above it is not stopping the server. If needed I have the screen output with set -x in the elasticsearch config file. |
I'm having the same issue on CentOS 6.5 with elasticsearch 1.3.2 in OpenVZ. |
Same issue with LXC and Ubuntu 14.04
though elasticsearch is running, is it a huge problem for production environment? |
I also get this error on VPS running Ubuntu 14.04 when I (re)start Elasticsearch but is running at least.
|
Can someone please merge this? This works! 👍
|
@jogaco Absolutely no practical consequences other than having this message in the logs |
@spinscale, this issue is still linked from the TravisCI docs, maybe we can look into it? |
@karmi it is trivial to add another check if the proc file is writable and silence out the message, I just tested that locally on non OpenVZ and everything works as expected. What I dont know is, if just adding another check, that checks if the file in the proc file system is writable, actually changes anything for OpenVZ users. Maybe one OpenVZ user can shed some light on this? If we check for being able to write |
same problem on ES 2.3.0 Ubuntu 14.04 |
there is no solutions for this problem? fresh install of ubuntu server will be fix them? |
this is caused on ubuntu 14 on proc/sys/vm permitted |
now i know the problem is on server host is use openvz or any virtualization that doesnt support editing |
then it is posible on how to make elasticsearch and java not without editing this request |
omg help mee |
@rectoid The bug isn't causing any actual issues. Your Elasticsearch will work fine. It's just annoying to see in the logs. I can't believe it's been over 2 years. |

Same on 2.4.1, Ubuntu 14.04. |
steps that i took to make es 5 run in an environment when i can't change vm.max_map_count
but remember, es will run on DEVELOPMENT mode here is my workaround for making it run inside docker container |
You should not have to. My is running fine, except that error/warning message... |
As of 5.0, Elasticsearch will not start in production mode if |
@arypurnomoz Your workaround is overly complicated if all you want to do is expose a node via HTTP on an interface other than |
you should provide a flag to prevent this check or better do not conduct it in development mode. this currently prevents me from running tests on travis.ci. |
I have this issue before and solved by running my docker container in privileged mode, The actual reason behind this error is quite simple, Elasticsearch needs to change the "vm.max_map_count" to run, so changing via sysctl by Elasticseach itself and action is denied due to lack of permission. The issue will occur even the it is also a root user(Docker). Simply run the container in privileged mode and this will fix the similar type of issues. root@Zion:/home/jeswin/dockerproject# docker run -i -t --privileged ecc4953c8296 "/bin/bash" |
When elasticsearch is bound to localhost it runs in development mode. This mode makes a few startup checks of elasticsearch less strict (they become warnings), allowing it to boot anyway. On circleci its servers the value for is too low and elasticsearch wont start. So we make sure we are running in dev mode so we can at least run our tests elastic/elasticsearch#4978 (comment)
This problem really drives me mad with docker !!!!!!!! --privileged does not work anymore, nothing works anymore!!!! memory is set, but not checked correctly by ES5.x so it tries to write for no reason! result: ERROR |
My version: elasticsearch: 5.6.4 (but not working 6.2.3)
result:

I changed permission with chmod 777 and I edited sysctl.conf in the last line with |
