aacraid and rotational 1 even for ssd disks
Hi.
I wonder if aacraid shouldn't properly inform kernel about sdd disk via /sys/devices/../queue/rotational flag?
Using 3.18.22 kernel and aacraid driver tells linux that all drives are rotational:
raid:
# cat /sys/devices/pci0000:80/0000:80:03.0/0000:81:00.0/host10/target10:0:0/10:0:0:0/block/sda/queue/rotational 1
lvm on top of that raid:
# cat /sys/devices/virtual/block/dm-*/queue/rotational 1 1 1
while this system has raid array of SSD drives only (INTEL SSDSC2BB30). No rotational disks.
Adaptec ASR8405 7.8-0 (32730) firmware.
