Recommended R81.20 size partitions on MDS Gaia initial setup

fjulianom — Tue, 24 Sep 2024 05:59:25 GMT

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?

Julián

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

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.

Julián

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.

Julián

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?

Julián

AkosBakos — Tue, 24 Sep 2024 10:54:58 GMT

Hi @fjulianom

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

Re: Recommended R81.20 size partitions on MDS Gaia initial setup

fjulianom — Tue, 24 Sep 2024 11:24:45 GMT

Hi,

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

Julián

AkosBakos — Tue, 24 Sep 2024 11:27:30 GMT

Yes, in this case you set 2 TB for disk

Ant 300 GB for system.root.

Am I right?

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?

Julián

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

Hi,

I have a meeting with PS yesterday and confirmed the free disk space indicated in the release notes corresponds to the System-root partition space, and, the system automatically reserves the same size aproximately for upgrades, as @AkosBakos said in a previous post. I have made a test. A disk of 2 TB, and I have allocated 500 GB for System-root, the system don't let me put more than 254 GB for the logs partition, because it selects at least 1230 GB for Backup and upgrade, as you can see here:

After the installation, I have checked with lvm_manager, and I have seen the following:

I see the 1230 GB of Backup and upgrade partition during the Gaia initial setup corresponds to 550 GB of Upgrade itself, and 680 GB of Unallocated space. Then, I think if I want to put a 2 TB disk, and 500 GB for system-root and the rest for the Logs partition, the only thing I can do is install the system and after the installation, move all the space from the Unallocated space to lv_log through lvm_manager. Is that right?

Regards,

Julián

Thanks for the info. i don’t install MDS daily 🙂

In my experience you don't need that much for the root partition. 100GB root should be plenty for 2 domains. I have an MDS here running 2 domains on a 75G root and it's only 49% full after a year of runnign and keeping up with regular jumbo's. Another 2 domain MDS is running 50G root with 54% used space, but that's only been recently installed.
