This is not a bug or an issue with Proxmox.
LXC does not currently support an individual load value per a container.
The load avg's shown in the container are node wide, it has been discussed on LXC multiple times but it is not yet found a simple and accurate way to report a container only load.
I would wait for all your data to move around and the repair to fully complete, then let a full set of deep scrubs rotate.
While an OSD is in repair state it won't be deep scrubbed, so could just be a "false" positive.
I would suggest marking the most full SSD OSD as out.
This will allow I/O to still hit the SSD (read) but CEPH will start to move the data from this SSD to the other OSD's, just stopping the OSD's will make any data on these SSD's unavailable.
Once the first SSD is completed you can continue...
From your ceph osd df you have couple of OSD over the full limit, this will stop any further re balancing otherwise these may hit the 100% mark and stop I/O.
Do you have a cache layer infront of the hdd pool using the 4 SSDs?
So have been testing out raw EC (no change) with CEPHFS and RBD in latest CEPH 12.x release.
Works fine outside of Proxmox, however trying to use a RBD within Proxmox that is created on an EC pool fails.

Have had a 3 node cluster running perfectly fine for month's, recently added a 4th node to this cluster (Same hardware DL160 G9, and same configuration)
For the last few nights every night around 11:40-50 the server will reboot it self, looking in the log's I am struggling to see...
I think your forgetting a hardware raid card requires absolutely no support in the Proxmox installer, as the installer just manages it as if you was installing directly to one single disk, what your asking is for them to make a system available to install and configure mdadm. Which again is...
