Ceph user here. Ceph works fine 99.9% of the time until it doesn't. In this case you get a bit panic and start to google, ask in IRC for help and take a look at the bug tracker. In all critical cases of the past we were able to recover and gained ceph experience. I guess this is how you become a ceph expert.
- luto 6y agocan confirm this on two 24 node / 100TB / 132 OSD clusters and ~2 years.
- elongatedMusku 6y agoGetting my feet wet with 3 nodes, 3 osds. Wish me luck.
- effie 6y agoCurious about Ceph, what feature are you using it for? Would it make sense to serve big number of websites, stored on 20 servers, using single Ceph filesystem with some SSD cache? Or am I better off having just 20 independent servers?
- hutrdvnj 6y ago> Curious about Ceph, what feature are you using it for? Mainly CephFS. It allows you similar to NFS to have a big shared filesystem over network. If you have clients that require access to a triple digit terabyte or petabyte sized filessystem, then you might want to consider ceph. > Or am I better off having just 20 independent servers? If you have 20 independent websites, then I would recommend to provide them their own storage. That is because if your ceph instance has a downtime, then all your 20 websites would be down simultaneously.
