Module: Zammad

Hello friends,

after I installed Zammad, the associated service Elasticsearch refuses to start working. Multiple reboots of the server brings nothing. The service is enabled but does not start.
Attached is the error message:

elasticsearch.service - Elasticsearch
Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: disabled)
Active: failed (Result: timeout) since Sun 2022-03-13 13:39:52 CET; 1min 9s ago
Docs: https://www.elastic.co
Process: 1413 ExecStart=/usr/share/elasticsearch/bin/systemd-entrypoint -p ${PID_DIR}/elasticsearch.pid --quiet (code=exited, status=143)
Main PID: 1413 (code=exited, status=143)

Mar 13 13:38:37 server.xxx.com systemd[1]: Starting Elasticsearch…
Mar 13 13:39:52 server.xxx.com systemd[1]: elasticsearch.service start operation timed out. Terminating.
Mar 13 13:39:52 server.xxx.com systemd[1]: Failed to start Elasticsearch.
Mar 13 13:39:52 server.xxx.com systemd[1]: Unit elasticsearch.service entered failed state.
Mar 13 13:39:52 server.xxx.com systemd[1]: elasticsearch.service failed.

Where is the error?

Regards…

Please check if there’s enough free memory.

You may also check /var/log/elasticsearch/elasticsearch.log to get more information about the error.

EDIT:

I’m working on a nethserver-zammad5 docker version, the current module is bound to version 4 because native install of Zammad 5 isn’t possible anymore, see Zammad ticketing/helpdesk on Nethserver available - #169 by mrmarkuz

Maybe this helps:

/usr/share/elasticsearch/bin/elasticsearch-plugin remove ingest-attachment
/usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment

systemctl enable elasticsearch
systemctl restart elasticsearch
systemctl status elasticsearch

Hope this helps

My 2 cents

Hello mrmarkuz,

here is an excerpt from the log:

This seems to be the relevant error:

[2022-03-13T13:17:57,018][ERROR][o.e.b.Bootstrap ] [xxx.com] Exception java.lang.IllegalStateException: failed to obtain node locks, tried [[/var/lib/elasticsearch]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?

It happens immediately after loading the ingest-attachment, did you try to start elasticsearch without the plugin?

Please also check permissions:

ls -ld /var/lib/elasticsearch

After searching I found that others solved this issue by deleting lock files. If you don’t need elasticsearch for other apps, you could try it:

I never tested but it should work to delete write.lock files under /var/lib/elasticsearch .

cd to relevant directory:

cd /var/lib/elasticsearch

Find and delete write.lock files:

find -name write.lock -delete
