Insightful. Thanx!
is it possible to create backup of data to tape (for long-term cold storage)?
After we installed the Hammer version of Ceph in 2016, we changed the the placement settings. The result was that on every signle OSD we got a very high cpu load. Our vender couldn't find an answer and we need to reinstall the ceph cluster. Luckely the system was still in testing. At the end it is still one box and wrong configuration could impact the whole cluster. We had a headache. But, when verything is running smootly, it's a fine system. Now, we are in the progress of upgrading ceph Nautilus to Pacific and this makes our heart beat faster because when someting is going wrong it has a big impact, but no headache yet.
That's why I like zfs replicating to an other system, they are 2 totally independent systems. If you messed up one system when configuring, you have still the other one. Yes, storage is hard.
clustering is so hype
I have worked in data science for almost a decade and experimented with Lustre, GlusterFS, BeeGFS, MoseFS and OneFS at the 100+ petascale levels of capacity. Have you ever setup Ceph? It's horrendous in terms of setup, management, and troubleshooting. It's arguably one of the most horrendous software stacks I have ever used in production environments.
