FMC readiness check fail while upgrade from version 6.6.4 to 7.0.5

[longtran4679]

Greetings,

I ran readiness check before the upgrade 6.6.4 to 7.0.5 on FTD Firepower 2130. I got error message:

"SCRIPT NAME: 000_start/410_check_disk_space.sh
RECOVERY MESSAGE: Not enough disk space available in /ngfw(Filesystem:/dev/sda4) to perform the upgrade.(Current available disk space: 62239752KB. Minimum required disk space: 116535669KB)."

Verify the disk, I see it have 65GB available but it is still not enough. /dev/sda4 xfs 136G 72G 65G 53% /ngfw

I found the folder "db" has 51GB. 

root@dc2-bos-fw-1:/ngfw/Volume/root2/ngfw/var/cisco/deploy# du -sh *
51G db

root@dc2-bos-fw-1:/ngfw/Volume/root2/ngfw/var/cisco/deploy/db# du -sh * | sort -rh | head -5

182M 81604379708
174M 38654983044
174M 38654978829

Could you advise if I can delete files in this folder ? 

Thanks in advance,

Long

If the db folder is the one taking up too much disk space, do not directly delete any files there.

Instead, open a TAC case and have them verify that's the only feasible place where too much space is being used. If they confirm that, it may be necessary to rebuild the database which must be done with TAC guidance using some scripts.

Failure to do so according to these steps may result in corrupting the server altogether leaving you with an unusable system.

Sorry for my late reply. I created ticket to Cisco but still waiting for a WebEx session. I will update here if have any update from the TAC.  Marvin, Appreciate your input!!!

I clean up old folders in this path /ngfw/Volume/root2/ngfw/var/cisco/deploy/db# , it fixed the issue. 

Notice, I got same issue on 2 FP1140, I did the same and now all 3 FP passed the readiness check, no issue. 

Thank again Marvin for helping us.

@jorge.olivera check for large files by running the following (as root user):

find /Volume -type f -exec du -Sh {} + | sort -rh | head -n 15

Please share the output.

Hello,

I also encountered the same problem. Which files did you delete from the directory you mentioned? Will it cause a problem if I delete the files in this output?
