Add a blkio restriction to bastion cgroups
Closed, InvalidPublic

Description

It is possible to use enough IO on a tools bastion (which loads home directories via NFS) to make login and other general activities they are intended to support very slow.

Adding a limit using the cgroups mechanism now in place should help with that.

Except that NFS may not be maintainable via blkio restrictions. Will verify if that is true and close the ticket if so.

On looking, it doesn't seem possible through this mechanism. Another one will be needed for this.

Out of curiosity, could you share the tests you did? :-) I would like to understand why cgroups can't handle this.
