StarWind Software

Hello

We are currently testing StarWind VSAN with Proxmox VE and the StarWind Proxmox VE SAN Integration, and we came across a question regarding the maximum VM disk size.
When we create a guest disk on storage with starlvm, we receive a message indicating that the 64 KiB chunk size only allows drives smaller than 15.88 TiB.

Unfortunately, we couldn’t find any information about this. Is there a way to adjust the chunk size when creating the storage, or is it fixed by design?

Thx in advance

Hi,

This is more a question of Proxmox configuration rather than StarWind VSAN. You can change the chunk size in the config files.

Hi

Thank you for the advice. I just found that you can change the default chunk size in /etc/lvm/lvmlocal.conf under "allocation -> thin_pool_chunk_size = 64". So all new VM disks are created with a bigger chunk size.

You are welcome! I am happy I could help
Yes, chunk size can be tricky.
