[Octopus] OSD overloading

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

 



Hello,

I've a issue, since my Nautilus -> Octopus upgrade

My cluster has many rbd images (~3k or something)
Each of them has ~30 snapshots
Each day, I create and remove a least a snapshot per image

Since Octopus, when I remove the "nosnaptrim" flags, each OSDs uses 100%
of its CPU time
The whole cluster collapses: OSDs no longer see each others, most of
them are seens as down ..
I do not see any progress being made : it does not appear the problem
will solve by itself

What can I do ?

Best regards,
