Managed Disk Space


Cannot update cluster due to every node

not having enough space - The documentation calls for 5GB in /opt/dynatrace-managed but every node has the same message and cannot update:

Not enough free space (2 GB) on filesystem "/dev/mapper/appsvg-lv_OptDynMan". At least 3 GB is required for locations: "/opt/dynatrace-managed" Not enough free space (1 GB) on filesystem "/dev/mapper/rootvg-lv_opt". At least 2 GB is required for locations: "/opt/dynatrace/oneagent"


I've checked and it looks like when the node downloads the latest 'upgrader*.jar' it puts the file system under the needed space.

Any suggestions? We need to make sure we have the space mapped out correctly for our unix team to give us the space.

Appreciate any help,

I've also encountered this issue at a PoC installation. Even if you configured your filesystem sizes according to the manual. The 5GB mentioned in the docs is enough for the dynatrace itself. It's not enough if you want to upgrade it what is happening every month 🙂

Have the /dev/mapper/appsvg-lv_OptDynMan increased to 10 or 15GB and it will be fine.
