Disk is full

I have changed database pool size and sidekiq concurrency to 25. Hopefully this fixes the issue.

@praveenarimbrathod It was 15. I increased it to 20. The max limit is 25.

Comrades Again we have trouble connecting with other pods. Already more than 24 hours with the problem.

Sorry to be once again the bearer of bad news.

@juansantiago thanks for the heads up, we got another report of the same problem from another user as well. I have increased sidekiq workers to 2 and which means it can handle 50 connections now. But it seems mysql is not able handle such load. There is some discussion here https://poddery.com/posts/1304598 anyone familiar with mysql tuning please suggest.

-------- Recommendations -----------------------------------------------------
General recommendations:
Add skip-innodb to MySQL configuration to disable InnoDB
Enable the slow query log to troubleshoot bad queries
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Variables to adjust:
query_cache_size (> 16M)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
table_open_cache (> 400)

query_cache_size is now increased to 24MB.

I can see mysql is loading the server very heavily. We have to switch to postgresql immediately.

Another action that can help things better is to move out all other sites on the server. @manukrishnantv what can we do here?

I remember having a copy of an old DB also active in the mysql server, but not being used, which if exists will surely take more than 3GB. Removing that might also increase mysql performance for now.

poddery is now offline :(

@juansantiago I just checked and things look fine. Its working fine for me here.

I do not understand what happens, I can not access the from browser to domain and from another pod, I access to the profiles but the images are not visible.

@juansantiago Seems like there are issues. My account is not primarily on poddery. When I logged into one of the accounts now, the stream is loading too slow.

@praveenarimbrathod @balasankarchelamat Has anyone changed the settings with the admin panel? Can't access the sidekiq status now from the poddery admin account.

Shall we disable new user signup till the issues gets fixed? Seems like it seriously affects the user experience, mostly during peak usage hours.

@manukrishnantv yes, lets disable new sign ups for now.

can't find rake when trying to start server, now running bundle install

@manukrishnantv I have disabled new sign ups now. Lets move smc site off the server soon.

@manukrishnantv No, I never touch admin account.

News? I have convinced some groups that use Diaspora and have recommended poddery , now people ask me what happens

I suppose that you will be working to solve the problem and not good time to ask questions about it, but I am dedicated to promouthing the using free networks, I have had success in the past weeks and this is a problem on this struggle.

@juansantiago We are working to solve issues and it appears disabling signups for now is better than providing a bad user experience for the new users. After all, diaspora is distributed and there are other pods which could accommodate and connect the users.

Right now, we have multiple issues and we are working on it with the communities involved.

Unfortunately my knowledge is not enough to offer help to resolve problems, but if I do something, I'm here.

If it possible, I would like to receive periodic information to inform some poddery users who are not in loomio.
