Don’t worry @steevej , who knows how many times I skip whole parts to read

Would you consider downgrading, if in this situation yourself?.. As suggested in this post?

MONGODB_CONFIG_OVERRIDE_NOFORK after upgrade to 5.18 Installation & Upgrades

Hi, just updated my test server (Ubuntu 20.04) from a previous 5.x release to 5.18 and I’m now getting this error when restarting: Environment variable MONGODB_CONFIG_OVERRIDE_NOFORK == 1, overriding “processManagement.fork” to false Mongod is configured to run as a single-node replicaset on this server, more details here: storage: dbPath: /var/lib/mongodb journal: enabled: true oplogMinRetentionHours: 24 systemLog: destination: file logAppend: true logRotate: reopen path…

Thanks for your support

Sam

Hi @sam_ames,
Is selinux disabled?
The error now Is changed:

sam_ames:

{"error":"Location28596: Unable to determine status of lock file

In the extreme case, I would attempt to remove the files under the path /data/var/lib/mongodb (if you haven’ t collection populated with document in your istance) because seems corrupted the lock file or as you’ve suggested, try a downgrade or update.

Regards

sam_ames · 2023-08-11T18:23:15.478Z

It is a difficult install, I don’t even know what is se Linux is to be perfectly honest

Thanks,
Sam

I will try your suggestions on Monday morning, many thanks

sam_ames · 2023-08-11T18:23:56.385Z

Default install of Ubuntu **

Fabio_Ramohitaj · 2023-08-11T19:30:31.680Z

Hi @sam_ames,
cat /etc/selinux/config
Let me know how it will go then!

Regards

sam_ames · 2023-08-13T10:14:09.050Z


sysadmin@soft-serve:~$ sudo cat /etc/selinux/config
[sudo] password for sysadmin: 
cat: /etc/selinux/config: No such file or directory

It seems like your suspicions were correct.

Please suggest how I can resolve this. I did not delete selinux and am not sure why it’s missing.

Thanks for the support,

Sam

Fabio_Ramohitaj · 2023-08-13T12:27:33.937Z

Hi @sam_ames,
Another way to get selinux status Is toselinux status with the command
getenforce or cat /etc/sysconfig/selinux.
If the getenforce command results in output of the type enforcing or permissive, use the following command:
setenforce 0.
But as suggested in a previous post, i think is better to clean your data directory or do and update for resolve the problem
Regards

sam_ames · 2023-08-14T08:37:59.903Z

Please see the following output.

sysadmin@soft-serve:~$ cat /etc/sysconfig/selinux
cat: /etc/sysconfig/selinux: No such file or directory
sysadmin@soft-serve:~$ getenforce
Command 'getenforce' not found, but can be installed with:
sudo apt install selinux-utils
sysadmin@soft-serve:~$ sudo getenforce
[sudo] password for sysadmin: 
sudo: getenforce: command not found
sysadmin@soft-serve:~$

Do I need to install selinux tools?

Thanks,
Sam

Fabio_Ramohitaj · 2023-08-14T08:40:29.479Z

Hi @sam_ames,
In theory no, it should be present by default in the os.
Try the solutions discussed last time and let me know if they work

Regards

sam_ames · 2023-08-14T09:23:16.900Z

I can’t swipe the data volume because it is part of a raid partition and it was very complicated to set up.

However, I can delete everything in the directory that I have personally added. Is this worth doing?

You previously mentioned a downgrade, which version should I consider? I think I am currently using the latest release of version six. The post I shared, which mentioned downgrading was quite an old one so I assume the recommended version is no no longer the optimal solution.

Thank you,
Sam

sam_ames · 2023-08-14T11:31:40.014Z

All I’ve done is done is changed the directory. I’m amazed that this is so complicated…

Thanks for supporting me, Fabio

Fabio_Ramohitaj · 2023-08-14T14:49:50.335Z

Hi @sam_ames,
Great!!

Regards

sam_ames · 2023-08-14T15:27:53.955Z

Sorry, I wasn’t clear. The problem is not resolved, I was just complaining about how complicated this issue is to resolve.

Fabio_Ramohitaj · 2023-08-14T20:55:39.279Z

Hi @sam_ames,
Sorry, I didn’t understand before.
Now what problem is indicated to you by the logs and systemctl status?

Regards

Hi @sam_ames,
So you created a new data directory, gave all the correct permissions to this new data directory, and you get the same error again?

The only thing I have done is installed the os, made a volume group and fresh volume with luks, mounted it at /data and added my project source code to within /data.

Here are the commands I used:

Create encrypted software Raid1 volume 
To use all free space to create a soft raid 1 mirrored across 2 disks: 
Check volumes, space used and available with: 
sudo fdisk -l 

Create a new partition on /dev/sdb:
sudo fdisk /dev/sdb 

Use the options "n" (new partition), "p" (primary partition), and accept default partition number, starting sector, and ending sector to use the remaining space. 
Use "w" to save the changes and exit. 
Create a new partition on /dev/sdc:
sudo fdisk /dev/sdc

Use the options "n" (new partition), "p" (primary partition), and accept default partition number, starting sector, and ending sector to use the remaining space. 
Use "w" to save the changes and exit. 
Set up RAID 1: 
Run the command following command, but (if different) replace with the new partition you created previously with the other new, matching size partition:
sudo mdadm --create /dev/md4 --level=mirror --raid-devices=2 /dev/sdb5 /dev/sdc5 

Verify the RAID 1 array is synchronized: 
watch cat /proc/mdstat 
 Encrypt the RAID array: 
sudo cryptsetup luksFormat /dev/md4  
Type "YES" and enter a passphrase when prompted. 
Open the encrypted RAID array: 
sudo cryptsetup luksOpen /dev/md4 raid_encrypted  
Create a physical volume (PV) on the encrypted RAID array: 
sudo pvcreate /dev/mapper/raid_encrypted 
 create vg 
sudo vgcreate ubuntu-vg /dev/mapper/raid_encrypted 

create vg 100% available space: 
sudo lvcreate -n encrypted_volume -l 100%FREE ubuntu-vg 
 Format the encrypted volume with a ext4: 
sudo mkfs.ext4 /dev/ubuntu-vg/encrypted_volume 
 sudo mount /dev/ubuntu-vg/encrypted_volume /data 
 sudo mdadm --readwrite /dev/md127 
 watch cat /proc/mdstat

If you think it will make a difference, I can start over by reinstalling and using fresh Ubuntu 22.04.

I wiped the /data volume previously and it broke the ubuntu ssh… It seems like /data/lost+found is quite important.

Sam

sam_ames:

Not important and it won’t ‘break’ ssh. It might prevent login via ssh is a users home directory was under /data.

sam_ames:

sudo mkfs.ext4 /dev/ubuntu-vg/encrypted_volume

Only xfs filesystem is recommended for mongodb (data directory).

Please read further production notes in the manual.

Is this a brand new install or did you copy your existing database files into this directory, are there any files in the dbPath?

You could try the following:
sudo -u mongodb mongod -f /etc/mongod.conf --repair

And then see if it will start via systemctl.

Another possibility is incompatible permissions along the rest of the path, though I would expect a different error. Check that mongodb or ‘others’ have read and execute on /data /data/var /data/var/lib
