Tip of the week: don't use Intel 530 SSD's for journals

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If you are like me, you have the journals for your OSD's with rotating
media stored separately on an SSD. If you are even more like me, you
happen to use Intel 530 SSD's in some of your hosts. If so, please do
check your S.M.A.R.T. statistics regularly, because these SSD's really
can't cope with Ceph.

Check out the media-wear graphs for the two Intel 530's in my cluster.
As soon as those declining lines get down to 30% or so, they need to be
replaced. That means less than half a year between purchase and
end-of-life :(

Tip of the week, keep an eye on those statistics, don't let a failing
SSD surprise you.

Erik.
