Hi, Dear ceph-devel
I met a issue: Ceph osd rm one osd cause 30% objects degraded.
Step 1:
#created a ssd root
ceph osd crush add-bucket ssd root
Step 2: Installed a osd.100 failed:
94 1 osd.94 up 1
95 1 osd.95 up 1
Hi:
I'm new to ceph and when I 'm reading ceph code, I find it
hard to understand the semantics of PG::info::last_update and
PG::info::last_complete (even after reading the comments in code..),
so would you please give a explanation on the two fields and their
semantics and their usage
Please do!
