Resize Dataset not possible

My DataSet is using POSIX Permissions.
I am trying to resize the quota from 4TiB to 5TiB but can’t because TrueNAS keeps telling me

[EINVAL] pool_dataset_update.aclmode: Must be set to DISCARD when acltype is POSIX or OFF

I have no idea what to do. I tried to edit the Permissions to ACL but the presets say

  • POSIX_OPEN
  • POSIX_RESTRICTED
  • POSIX_HOME
  • POSIX_ADMIN

and choosing one obviously will not get me a proper ACL-Permission-Set. I am not sure but changing from POSIX to ACL does not seem to be an option. All I want to do is change the quota for the one DataSet. I hope somebody will be able to help me.

Thanks in advance!

You need to go into the dataset settings and change the aclmode for your dataset to DISCARD.
