anyone experienced this weird error. i dont find any reason for the disk to be full since it is still running at 45%.
tried clearing some log files on these directories but still the error still present
and also tried from these forum.
despite all of those actions the error still present.
Solved! Go to Solution.

What about if you are getting this error in FMC, but the firewalls don't show any signs of what I would consider excessive disk use, nor do I find any deleted files when I run the command everyone refers to "lsof | grep deleted". I don't see anything that would merit an alert about disk space or disk usage in the output below.

Hi Sir,
Try checking the log files from these directories below and if you find something that is defined below then you can delete it then run the "lsof | grep deleted" command again.
after deleting you need to run the restart diskmanager "pmtool restartbyid diskmanager"
then run the "lsof | grep deleted" command

@derek.small it's the /ngfw folder that the alert is triggering on. So check it with "df -k /ngfw".

Having the same issue but i don't have output for lsof | grep deleted
bpnfw04:~$ df -k /ngfw
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda6 41943040 41660476 282564 100% /ngfw

Hi Sir, it seems that you have not entered sudo su - after entering expert mode.
You need to enter "sudo su -" and it will ask for you password then thats the time you can run the lsof | grep deleted.

Still not seeing a problem...... FMC seems to think 34% used is a problem but that seems pretty rediculous.

@derek.small please check your diskmanager.conf file.
root@firepower:~# cat /etc/sf/diskmanager.conf
diskmanager
{
version 1;
warnings
{
percent_exceeded 19;
}
<snip>
Some use cases result in the "percent exceeded" value to be incorrect, resulting in false positive errors.
04-06-2023 04:51 AM
What is the correct value? 19% seems a bit low.

Anyone know if there are any new "high unamaged disk"bugs related to version 7.0.5?
This particalur bug was suposed to be fixed in 7.0.5, but I just heard from another customer reporting the same error with 7.0.5.
I haven't had any time yet to investigate the device yet, so just wanted to check if someone still having this error with 7.0.5?
Thanks

the only version I have actually seen with this fixed so far is 7.2.x
11-13-2023 04:15 AM
So far after upgrading my ftd to 7.0.5 until now 7.0.6 i havent encountered the same problem anymore, fingers crossed! However, i have this other bug related to CPU which is still ongoing. What happened to Cisco? Their system is so buggy lately! Made me think of switching to other brands. So frustrating. One bug got fixed bug a new release but another new bug comes up! What in the world!
