Recommended R81.20 size partitions on MDS Gaia initial setup

[fjulianom]

Hi guys,

On a MDS Gaia initial setup, I find this:

How do I size this? Shall I size based on my logs requirements and the auto assigned size for system-root will be fine? Or there is a minimum size for system-root that I have to take into account?

Regards,

Julián

Hi @fjulianom,

• You will have SmartLog server?
  • If not, the 20 GB-s for the logs is nothing 🙂
• A rule of thumb is -> you need as many free space as the SYStem partition size. This needed for upgrade (when the auto-snapshot happens)

Overall, you can extend the volumes anytime you want.

Hi Akos,

No, I don't have a SmartLog server. That's screenshot is only an example for knowing I am talking about. I will have around 1.5 TB for logs, so I will give a 2 TB disk. With this, the default values Gaia gives for a 2 TB disk are:

And when assigning 1.5 TB for logs, the system-root changes to:

Will this be fine?

Hi @fjulianom 

Based on the available information, I would say yes. 🙂

For MDS you need alot of space in root partition, I would not go under 100Gb

[fjulianom]

Hi guys,

Thank you for your recommendations. @Martin_Raska it makes sense what you say since I checked my current MDS disk space and has 100 GB in root partition. But is there any official documentation where I can find this recommendation? Some times when I open a TAC case to ask about these things they reject it because is not a technical issue.

Here you can see it all: https://sc1.checkpoint.com/documents/R81.20/WebAdminGuides/EN/CP_R81.20_RN/Content/Topics-RN/Open-Se...

Hi,

Not all. In that link it says for MDS a recommended free disk space of 1 TB (whole disk), but it doesn't says the recommended root partition size.

Hi @fjulianom 

Point 1 and 2: for the first domain 100GB and any additional domain plus 110GB

Hi,

Yes, I am clear about that, I see those values. But those values are for free disk space (whole disk?), but what value for system-root partition size? You must configure this value in the inital setup:

Recommended 1 TB for the disk.

Minimum

• If you have 1 domain: 100GB
• If you have 2 domains: 210 GB
• If you have 2 domains: 320 GB

Make sense?

Hi,

It makes sense, but imagine I have a 2 TB disk and I have 2 domains, do I have to enter 210 in system-root partition in this screen during the initial setup?

Hi @fjulianom 

At least 210 GB but I round it up to 300GB

Hi,

Ok, then I assume free disk space = system-root partition space. That was my original question.

Julián

[AkosBakos]

Yes, in this case you set 2 TB for disk

Ant 300 GB for system.root. 

Am I right?

[fjulianom]

Hi,

No, that's not the right image. The following is the right one:

A disk of 2 TB and system-root of 300 GB. And this gives me a maximum of 914 GB for logs partition. Then, when the document says "Recommended 1 TB for the disk.", does it mean recommended 1 TB for system-root partition?

Regards,

Julián

[AkosBakos]

That should be OK. You can add disk for the LOG almost anytime. 

[fjulianom]

Hi,

But I don't think the Minimum free disk space of 110 GB for each additional Domain corresponds to system-root. I have a customer with a MDS and 9 domains plus the global domain, then he will need a 1090 GB for system-root partition. And this is his partitions size:

Doesn't make sense, right?
