Disk Capacity Detection

Hi,

I've recently started using the disk resource, and it seems like mesos
slaves only detect disk resources mounted on the root directory. Is there
anyway to point mesos to storage mounted elsewhere? Should I just pass what
I know to be the cumulative storage to the resources flag?

Thanks!
Chris

Thanks for the answers! The workaround did what I was looking for.

Thanks again,
Chris

Chris,

There is a workaround.  If you wrap up your storage devices prior to
starting Mesos, then you can transparently use multiple disks as a single
disk.  See [1].

Chris, Mesos currently only supports a single disk. In other words, if you
have multiple disks, Mesos can only manage one of them. You can choose
which disk to use by setting --work_dir to the appropriate directory under
the given disk.
