Re: [ceph-users] rbd and cephfs (data) in one pool?

All of the metadata for the filesystem resides in a different pool from the data so I doubt it would "format" the pool land erase the RBDs. Again, though, not a supported use case which means future releases could do something to mess it up and it wouldn't be a bug to be fixed as it isn't a feature

[ceph-users] bluestore store keyring

Hi all， I am a newbie， and have a question about bluestore osd keyring： after osd host reboot， I used “ceph-volume trigger” to start osd, but key in keyring file changed, osd can not startup. so I must modified keyring manually after every reboot. bluestore mount osd using “tmpfs

[ceph-users] slow osd problem

Hi all. In general - one single slow osd significantly affects the whole cluster of rbd clients. If just one osd in rbd pool has significantly increased latency, for example 30ms, while others are 0-1ms. For any reason, not crashes but just slowed down. Than every rbd client (application) will

Re: [ceph-users] Cache tiering on Erasure coded pools

Also carefully read the word of caution section on David's link (which is absent in the jewel version of the docs), a cache tier in front of an ersure coded data pool for RBD is almost always a bad idea. I would say that statement is incorrect if using Bluestore. If using Bluestore, small
