[PVE-User] Ceph: sudden slow ops, freezes, and slow-downs

[Branislav Viest <info@branoviest.com>]

Hello, 

I have experienced some serious difficulties with our Ceph cluster built-in from 4 nodes. I have created a proxmox forum topic regarding this problem and I think it is useless to type all the information in this mailing thread. I would like to ask you guys to check it out and if anyone has any idea what should cause this problem, what should be a problem, or how to solve it, I would be very sincere and thankful. Any idea or your experience is worthy. 

We have already begun the migration process to another provider but I want to know the answer or the problem roots anyway to prevent possible failure or problems after migration. 

The topic is here: [ https://forum.proxmox.com/threads/ceph-sudden-slow-ops-freezes-and-slow-downs.111144/ | https://forum.proxmox.com/threads/ceph-sudden-slow-ops-freezes-and-slow-downs.111144/ ] 

Thank you all.
