Big-IP virtual edition not loading configuration

[v2]

Hello.

i have a virtual edition of Big-Ip that is not loading the configuration. am getting the following message on the CLI 

load_config_files[8736]: "/usr/bin/tmsh -n -g -a load sys config partitions all base " - failed. -- Unexpected Error: No user configuration is found. Loading process is aborted.

2023 Feb 6 03:42:41 BIG-IP-01.lab.local load_config_files[8736]: "/usr/bin/tmsh -n -g -a load sys config partitions all base " - failed. -- Unexpected Error: No user configuration is found. Loading process is aborted.

I  tried to load the config manually but its giving the same error:

[admin@BIG-IP-01:INOPERATIVE:Standalone] ~ # tmsh load sys config

How can i resolve this without wiping the configuration?

@v2 you might try this article and see if that fixes your issue.

I tried running the fsck as the recommended action but it looks like that tool is not available:

[admin@BIG-IP-01:INOPERATIVE:Standalone] / # fsck -p
fsck from util-linux 2.23.2
[admin@BIG-IP-01:INOPERATIVE:Standalone] / # fsck
fsck from util-linux 2.23.2

@v2 What code version are you running on this device?

[boneyard]

You tried the command, but did you check if those three files exist and are not 0 bytes?

/config/bigip_base.conf
/config/bigip_user.conf
/config/bigip.conf

[v2]

The files were there but with 0 bytes, i also had backup copies of the files, so what i did is to copy the .bak files and replace the .conf files, now the Big-IP has booted prperly.

Thanks.
