Internal Server Error on Search

Hi there,

Having an error on Seafile Pro, on which I receive ‘Internal Server Error’ on the search page.

seahub.log shows the following:

I saw some other posts that made reference to elasticsearch logs, however nothing has come up in those. The last entry in the elasticsearch.log is from 5 days ago which had a ‘high disk watermark exceeded’ error – my disk was full a couple of days ago, but i have expanded the drive size now, and there is still 80GB available.

Any clues?

The search uses elasticsearch. It looks like elasticsearch is either not running at all or at least not accepting connections (Failed to establish a new connection).

Ok thanks. Based on some web searching I did a test from the command line to see if elasticsearch was running:

root@x:/data/seafile# curl -X GET http://localhost:9200
curl: (7) Failed to connect to localhost port 9200: Connection refused

now doing a

netstat -a | grep 9200

returns no results.

i’m a bit stuck as to how to get elasticsearch to start running, as my searches so far point to restarting the ‘elasticsearch’ service (using ubuntu FYI), however elasticsearch is an unrecognized service:

root@x:/data/seafile# service elasticsearch status
Unit elasticsearch.service could not be found.

would anyone have anything further to point me in the right direction?

thanks.

Seafile delivers a bundled version of elasticsearch. It should be within the install directory. I’m not into how it is started an managed, though.

There is definitely elasticsearch folders in the install directory:

/data/seafile/seafile-pro-server-7.0.9/pro/elasticsearch/
/data/seafile/seafile-pro-server-7.0.9/pro/python/elasticsearch/
/data/seafile/seafile-pro-server-7.0.9/pro/python/elasticsearch-5.5.0.dist-info/
/data/seafile/seafile-pro-server-7.0.9/pro/python/elasticsearch_dsl/
/data/seafile/seafile-pro-server-7.0.9/pro/python/elasticsearch_dsl-5.4.0.dist-info/

i’m hoping one of the devs could maybe offer some insight? otherwise i might have to log an email directly with them as i’m out of ideas at this point.

Hi adam,

I ran into the same issue before. The cause of this for me is quite simple.

First, check if elasticsearch process is running:

~$ ps -aux | grep elastic

You shouldn’t see any process related with elasticsearch.
Then, check if the pid exists.

~$ ls haiwen/pids/elasticsearch.pid

The pid should exist.

If the above two steps match what I describe, then congrats, you ran into the same issue as I have.

Solution is pretty straightforward: delete the haiwen/pids/elasticsearch.pid, and restart seafile server. Check the elasticsearch process again and it should be running. Then seafile should get back to normal.

Fantastic, thanks for your help.

Deleting the elasticsearch.pid has fixed the issue for me.

Much appreciated!
