Bug Description

This could still be a bug.

LVM on a 64-bit CPU/Kernel should NOT have a 16TB limit. It should have a 8EB limit (exabyte).

https://www.redhat.com/archives/linux-lvm/2010-March/msg00007.html

Please pass this by the development team. I think the 16T limit in /usr/lib/python2.6/site-packages/fuel_agent/drivers/ks_spaces_validator.py was based on older 32-bit CPU/kernel.

could it duplicate this one https://bugs.launchpad.net/mos/+bug/1526845 ?

https://github.com/openstack/fuel-agent/blob/master/fuel_agent/drivers/ks_spaces_validator.py#L144

actually, 'Root file system must be less than 16T' is not true.

it seems that we could only resize rootfs image in 1024 times, so as was being initially made 8G it could only grows to 8T at most.

https://github.com/openstack/fuel-agent/blob/master/fuel_agent/manager.py#L97-L104

what type of fix is expected?

these are limitations of e2fsprogs package shipped with centos6.x

so yes, i was able to take a look into original ticket and according to fuel-agent logs it was:

2015-12-28 21:53:57 INFO fuel_agent.cmd.agent KeyError: 'mount'

therefore, it turned out to be a duplicate of https://bugs.launchpad.net/mos/+bug/1526845

however, https://bugs.launchpad.net/mos/+bug/1526845 should have been assigned to Fuel project, not MOS.
