My SO is Ubuntu 16.04 x64 with kernel version 4.13.0-45-generic and ceph

How I can debug why that CPU usage?.
Thanks!

Call ReleaseFreeMemory() to release freelist memory to the OS (via

Bytes released to the OS take up virtual address space but no physical

because there
is no quota on this cluster.
This will lower the petitions to MDS and CPU usage, right?

My last question is if someone can recomend me a good client configuration
like cache size, and maybe something to lower the metadata servers load.
Thanks!!

Hello,
Today I've decided to upgrade my Cep
For now I've added the nodown flag to keep all OSD online, and all is
working fine, but this is not the best way to do it.
Someone knows how to fix this problem?. Maybe this release needs to open
new ports on firewall?
Thanks!!

Hello,
My question is about steam security of connections between ceph services.
I've read that connection is verified by private keys and signed packets,
but my question is if that packets are ciphered in any way to avoid packets
sniffers, because I want to know if can be used through internet

I forgot to say that after upgrade the machine RAM to 4Gb, the OSD daemons
has started to use only a 5% (about 200MB). Is like magic, and now I've
about 3.2Gb of free RAM.

SPOF and I only can deploy an MDS, then we have a new SPOF...
This is to know if maybe i need to use Block Devices pools instead File
Server pools.
