Dear all,
I'm trying to migrate a vm that has two disk one over a nvme and the other over a lvm across four sata disk.
The nvme has 32gb and the lvm has 14Tb.
The migration is between two nodes non-clustered, with a 1Gb network between them.
All starts fine, tranferring 117Mbps the first nvme disk allways go fast.
The problem comes with the lvm disk, it starts allways at 115Mbps, and more or less when it has sended 23Gb it starts to slow down.
I opened a console and I run 'iostat 1', and I see the Kb/read column drop to 2900 Kb oscillating to 0 Kb.
I'm lost with this problem.
Thanks
