Increase Cisco FTD and FMC Default Disk size in VMware Workstation.

whizkidraj — Thu, 06 Apr 2023 11:43:46 GMT

Hello guys,

So as we deploy (add) the Cisco FTD and FMC in VMware Workstation with the .ovf file, the default disk size is very less and since we can thin provision, how can I increase this size to 2 TB.

Also, once I upgrade my Cisco FTD or FMC, does the upgrade process also cleans (deletes) the old version files automatically i.e. is anything needed to be done after the upgrade to clean the old version and any other junk files,
and if yes then which files and under what directory can I safely delete such or other files to keep the disk space clean and not being wasted from old version files or any other junk files / unneeded files.

Database table sizes are limited by the license in FMCv, so it doesn't help anything to increase the disk size. See "event storage space" in the dats sheet here: https://www.cisco.com/c/en/us/products/collateral/security/firesight-management-center/datasheet-c78-736775.html#Platformspecifications

Changing FTDv disk size doesn't affect performance in any way.

So.... on a tac call right now... 7.2.x is wanting more space... I've got 104G free and can't get a geo location update to install, it wants 118. TAC says they're talking 500G for new deployments... And no-one knows how to grow it when you add space. I'm sure I'm going to hear that I have to redeploy and backup/restore, which is completely asinine.

As noted in your teams space posting, I had a TAC case for this issue a couple of months ago. The TAC cited https://bst.cisco.com/bugsearch/bug/CSCwe44571 . The workaround was as follows:
Truncated the geolocation files using below commands.
```
OmniQuery.pl -db mdb -e "truncate geolocation_ipv4;"
OmniQuery.pl -db mdb -e "truncate geolocation_ipv6;"
OmniQuery.pl -db mdb -e "truncate geolocation_ipv4_country;"
OmniQuery.pl -db mdb -e "truncate geolocation_ipv6_country;"
```
Reclaimed 48 GB of disk space for a total of 130 GB available to use.

Just to clarify there is no way to increase the diskspace on the vFMC?

You can make the disk larger during installation (not after), but it won't enable storage of more events in FMC's database tables.

It will increase space available for system files, log files etc.

Thanks Marvin.

So... that's a way around the space issues we're hitting with the geolocation data? Fresh deploy to a bigger disk, then backup/restore the FMC to the new deployment?

At the moment... no.
I was told by TAC that there may be something coming in 7.4.1?

I'm getting an error trying these truncate commands:

Error: DROP command denied to user 'barnyard'@'localhost' for table 'MYD'

@thor1024 you need to run the commands as root user. So, first "sudo su -".

Yes there is a way, I have done it by increasing virtual machine disk by 100GB, then boot up from growpart live cd, resize partition /dev/sda7, and then proceeded with an vFMC update from 7.0.1 to 7.2.4 without errors.

Hi Marvin, I came across this bug but also there is a "defect" related to resizing the vFMC disk: CSCwf93791. The last time I deployed the ovf, it didn't allow me to modify the disk size and used forcefully thick provisioning. How did you manage to change the disk size during the installation? Did you use the ovf template? Thanks as always for your generous help!

Thank you, Marvin

We have the same problem after upgrage to 7.2

I use your truncated released a lot space, but now GeoLocation ACP rules stopped working.

I'm try to update GeoDB again, but FMC said already installed.

How can I rollback now?

Thanks,

David

I suggest working with TAC.

If that's not an option for you, you should be able to manually download an earlier version and install it using "System > Updates > Geolocation Updates"

Thank you for your fast reply.

The cover is in renew, but the services impacted.

I tried download last version GeoBD from Cisco, and use GUI to update, but FMC still says the version is already installed.

Then I SSH to FMC go to /var/ sf/updates, removed the file, then tried again in FMC guide, but after the upload, it will still say the version is already installed.

I will log a TAC case once the cover renewed.

Thanks again.

David

Hi Marvin,

Cisco just released a new GeoDB, after push the update from the FMC GUI, all back to normal.

Maybe 11-05 GeoDB got problem.

Thanks,

David
