All I’ve done is done is changed the directory. I’m amazed that this is so complicated…
Thanks for supporting me, Fabio

Hi @sam_ames,
Great!!

Sorry, I wasn’t clear. The problem is not resolved, I was just complaining about how complicated this issue is to resolve.
Hi @sam_ames,
Sorry, I didn’t understand before.
Now what problem is indicated to you by the logs and systemctl status?
Regards

Thanks,

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?
Regards
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.
Regards,
Sam
Not important and it won’t ‘break’ ssh. It might prevent login via ssh is a users home directory was under /data.
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
Thank you very much, if your terminal command doesn’t resolve this I will start over with the instructions that I compiled after my research, changing to luks with xfs.
This is a fresh database with no existing data.
That’s a huge help, please allow me a couple of days to follow all you have suggested; as I have other projects as well.
It’s unfortunate that my company won’t justify the paid version of mongo. I’m guessing that would be much easier to set up. We’re a tiny start up.
Anyway, thank you for your support and have a nice day.
Sam
