Hi,
Try looking for file locate in a folder named Slot X where X in the
number of the slot, then echoing 1 in the locate file will make the
led blink. :
# find /sys -name locate |grep Slot
Sorry, I forgot to say that in Slot X/device/block you could find the
device name, like sdc.
Cheers

SSDs were pretty new so I don’t we hit that sort of things. I believe that

Hi Alexandre,
thanks for the reply. As said, my switches are not stackable, so using LCAP
seems not to be my best option.
I'm seeking for an explanation how Ceph is utilizing two (or more)
independent links on both the public and the cluster
the only way to get working multipathing for Ceph.
