The activity rings on both of my hot plug drives rotates continuous (they are in RAID 1 configuration). The drive status on both is solid green.

Is this normal? The iotop command is showing no activity... Total Read/Write zero B/s.

Edit: However, I'm not sure if I'm using that command correctly. Just SSH'd while I had iotop on, it didn't pick up a file write...

Any advice would be great.

Whether there's read or write activity, the drives are still online and spinning!

Edit: This may just be a function of using the Dynamic Smart Array driver (hpvsa module).

HP explains the drive functions here.

Thanks for the reply. I browsed through both of those links, and they say the same as my user documentation - i.e., activity ring spins when there is activity... however mine is spinning non-stop - and I don't think I can see any processes doing anything? Is this still normal? – user3513346 Jun 9 '14 at 16:59
What model of server are you using? What operating system and version is installed? – ewwhite Jun 9 '14 at 17:01
Haha you're not going to like it. DL320e G8 v2. CentOs 6.5. – user3513346 Jun 9 '14 at 17:03
Then I suspect the Dynamic Smart Array driver (hpvsa module). Recall that this is a bit of a fakeraid. I wouldn't worry about it. – ewwhite Jun 9 '14 at 17:09
