Can't connect to NC after OS updates (maybe redis?)

johnmcd · May 6, 2023, 3:52pm

Nextcloud version (eg, 20.0.5): 25.0.6.1
Operating system and version (eg, Ubuntu 20.04): Debian GNU/Linux 11 (bullseye) on Raspberry Pi
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.56
PHP version (eg, 7.4): 8.1.18
redis version: ‘6.0.16’

The issue you are facing:
I’m running NextCloudPi on a Raspberry Pi 4, and being a good little doobie I try to regularly update my system with new patches (e.g. apt get update/upgrade). I’ve never had any problems until now - after upgrading this morning and rebooting I now get a ‘Service unavailable’ error when attempting to connect. I took a look and it seems like it might be related to redis, but I’m not a redis expert. I tried to do some research on the various possible issues but I just got more confused, so I’m hoping someone can help.

Is this the first time you’ve seen this error? (Y):

Steps to replicate it:

it looks like you did overwrite your redis.conf.
I will try to help:

Since redis normaly is run by user redis

and php/nextcloud is run by the ht-user (www-data), you need

unixsocketperm 777

I don’t know, how you start redis, but I would assume that you start it by systemd.
Then you would normaly need:

daemonize yes
supervised auto

You normaly would not need password protection, so the following settings can be removed:

requirepass ******
and
rename-command CONFIG “”

I would set:

stop-writes-on-bgsave-error no
maxmemory 1GB (or what your system needs, you have set to"0")
maxmemory-policy volatile-lfu
maxmemory-samples 10
appendfsync no
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-size -2
set-max-intset-entries 512
hll-sparse-max-bytes 3000

Then, since you have:

append this lines (if not yet done) to the php.ini of the php-sapi you are using (normaly php-fpm):

redis.session.locking_enabled=1
redis.session.lock_retries=-1
redis.session.lock_wait_time=10000

Much luck.

I wrote that, but I don’t know if that is a special way of connecting NextCloudPi to Redis. I’m not a Pi specialist.

jtr · May 6, 2023, 9:57pm

I’m a little confused about your query - but it might be because I haven’t touched NCPi directly in a long time - but I thought updates were handled differently when using NextcloudPi (even for the OS and certainly for major NC dependencies like Redis).

NCPi is a bit of a special animal because even though it’s running on Raspberry Pi OS 10/11 and you can touch the OS directly still, it’s usually better not to because the pieces are designed to work together in a special way. There are a lot of assumptions made across the board. It’s essentially its own little sub-distribution of Raspberry Pi OS tuned specifically for running NC in a very specific way (or that’s what you end up with once you install it - particularly outside of Docker).

Are you saying you bypassed the NCP update process?

I.e. Staying up to date

johnmcd · May 7, 2023, 12:00am

jtr - there were a number of security patches for various OS components that hadn’t been installed, and I was seeing a lot of unusual failed activity on my public Internet connection, so I made the decision to go ahead and do a manual update. I knew I was taking a chance, but I though it was worth it - apparently I thought wrong

johnmcd · May 7, 2023, 12:10am

ernolf - thank you so much! I made the suggested changes but I have a question - for the changes to the fpm php.ini file, is there a specific section I should place those entries in, or just append them to the end (which is what I did). After rebooting I still get the 503 message, it appears that progress has been made - I’m now getting a bunch of messages locks:

I went into the nextcloud MySQL database, but the oc_file_locks table is empty. I’ll keep looking.

Thanks again

I wanted thank you all again for your help with my issue. What I ended up doing is using the ncp-config utility to manually update my NC version to 26, which seems to have fixed my problem(s) as I can once again access my NC instance. I made sure to immediately do a full backup of my NC config, data and database, and I’ll avoid doing any manual OS updates going forward.

Thanks

John

This is for the next time:

This forum makes use of markdown syntax. That means it uses special characters and parses them for formating what makes your logfile echoes impossible to work with (I analyse them normally with jq in a terminal which is made impossible when broken by markdown formatting).

Please make use of the right markdown syntax in future and paste such long logfile echoes in a fenced code-block.

Will do - thank you.

Can't connect to NC after OS updates (maybe redis?)
