Description
As per David Fagan's requests:
Gerard,
Based on our brief conversation the right machines are from cmseos50 up, as you mentioned one at a time and see what happens.
Please let me know how things go, I'll watch the net lot of this will be local to a switch but I don't know if the space is totally all over the space or specific to nodes..
If I see a network top out I'll let you know, we are pushing but they aren't bouncing off the ceiling.thanks,
David.

So the drains are not working very well, will now set all this disks as Read Only and (re)start the drain only for one of the pools:

My new theory is that drains stall whenever they find files in error state, which means I'll have to go dig out all what's wrong in the FS:

I've noticed that the migration speed with a single FST was gradually decreasing speed. Since there are sooo many small files, I've increased the parallelism per FST migration from 2 to 20 transfers at a time, this boosted the transfer bandwidth back up :)
#4 Updated by Gerard Bernabeu Altayo about 5 years ago
With 20 the load increased very high in many FSTs, lowered it to 5...

In order to clear the running transfers, restarting cmseos50 & cmseos51 and then I'll look at each individual FST to clear them up.

Nodes keep draining, now it is time to look at the few remaining files and solve the individual issues, for exmample:
