I have an issue with my Vess R2600fi (dual controller) unit. I have started RAID10 array migration from 8x8TB to 14x8TB.
First, the migration is very slow, regardles of the migration priority (6% after 4 days at 20MB/s rate). I can blame ~400 I/O per second from VMs running on top of it, but I was expecting faster migration where there is no VM activity over night...
The bigger issue is that one of the source HDDs failed in between. I cannot rebuild the array because the migration is in progress, I cannot cancel the migration just because there is no such option.
Question: is there any hidden CLI command to stop the migration, rebuild and move VMs away?
Any other suggestions?
