Some Docker are not reachable anymore

Featured Replies

Hey guys
Hopefully someone can give me a hint what going wring on my system at the moment. 

Some of my Docker containers are not reachable anymore when i try to open the Web-GUI. i get the message that the site is not accessable.

 

The website is not accessible
192.168.0.22 has rejected the connection.
Try the following:

Check connection
Check proxy and firewall
ERR_CONNECTION_REFUSED

I have this issue only with some of the Dockers.

Here are some examples:
 

Plex: https://192.168.0.22:32400/

Deluge http://192.168.0.22:8112/

Linkwarden http://192.168.0.22:3000/

Radarr http://192.168.0.22:7878/


I already swapped the ports of the different Dockers and also deactivated the Anti-Virus and Firewall. 

Thanks for your advise.

Cheers Visuals

please post diag. Make sure docker that have a web ui are running in custom br0/bont0/eth0 and have there own IP

Docker ports replace host unraid ports and a webserve can break the gui

Any hint what i could try?
i uninstalled and reinstalled Deluge to see if this helps, but no success.

I still think this is due to a NVME disk failure as per your syslog/diagnostic...


Unraid diags don't capture everything its a part of the picture.. I would need docker inspect of the docker posted...

as example?
which docker image did your run for deluge?
image.thumb.png.435863e5829a28ad53df2808399f9e02.png

*ask on their support form...
 

As I'm not sure if you did a true uninstall and reinstall. as their are quite a few steps.
1 delete docker (with checkmark to delete image!)

2. add container, hit the x to remove the template.
3. Web terminal cd /mnt/user/appdata and remove the deluge folder and any other docker folders configurations...
4. CA store and install...

 

per your diag i show btrfs issues on nvme0np1 this needs fixed first!

*you may need syslinux commands to help with nvme issues, but this looks like the start of nvme disk failure...

 

Key Observations
BTRFS Errors:

Repeated checksum failures

BTRFS warning (device nvme0n1p1): csum failed root 5 ino 3277227 off 7759556608 csum 0xa3a491cf expected csum 0xf5514fe6 mirror 1

Web UI run a btrfs scrub and btrfs check file system... Double check smart on the disk.

 

as this will have a huge Impact on Docker, Since Docker containers often rely on BTRFS for storage, these errors could lead to instability or reachability of certain containers.

 

These can be run in the Web UI, but Here are the terminal comands...

 

Check BTRFS Health:


*stop all dockers as they will not write when the file system is fixing itself..

Run a scrub operation to verify and fix errors

btrfs scrub start /mnt/cache

Monitor the output using

btrfs scrub status /mnt/cache

*can have 2 webui terminals...

 

Backup Critical Data:

Immediately back up any critical data stored on the affected device to prevent data loss

*While the drive is functional..
 

Repair File system:

If the scrub does not resolve the issue, attempt a filesystem repair

btrfs check --repair /dev/nvme0n1p1

Ensure you have a backup before running this command. 

 

Verify Docker Configuration:

Check if the affected containers (e.g., Plex, Deluge, Linkwarden, Radarr) have their data stored on /dev/nvme0n1p1. If so, the BTRFS issues could be the root cause.

 

Consider Hardware Issues:

Perform diagnostics on the NVMe drive to check for hardware fault, run smart:

smartctl -a /dev/nvme0n1


daig has smart data this is what i see:
 

The SMART report for the NVMe drive (Samsung SSD 970 PRO 1TB) indicates the following:

Key Details from the SMART Report

Device Information:

Model: Samsung SSD 970 PRO 1TB

Firmware Version: 1B2QEXP7

Capacity: 1.02 TB (350 GB utilized)

No Immediate Errors Displayed:

The initial lines of the SMART report do not show critical warnings or errors.

Next Steps

To determine whether the drive is healthy, we should examine further details in the SMART report, such as:

Media and Data Integrity Errors

Endurance Stats

Critical Warnings

 

so this is more a btrfs scrub and filesytem maintenance issue.

Thanks a lot @bmartino1 for your advise

i have checked the Cache drive and found some uncorrectable errors, the question is what this means. Is there a hardware error and should i replace the drive?

 

root@THOR:~# btrfs scrub status /mnt/cache
UUID:             f9420902-2775-4d15-ab3d-be3218c586c8
Scrub started:    Thu Dec  5 07:55:36 2024
Status:           finished
Duration:         0:00:29
Total to scrub:   323.66GiB
Rate:             2.55GiB/s
Error summary:    super=3 verify=2
  Corrected:      0
  Uncorrectable:  2
  Unverified:     0

 

The Smart test was sucessfull and didnt found any errors.

 

i now repaird the filesystem, how can i check if this was sucessfull? 

(Sorry, im a noob in this area)

Look in the syslog for the list of corrupt files and then delete them/restore from a backup, keep monitoring the pool, if more corruptions are found there could be a hardware issues, like bad RAM.
