Hi,
I have a EC pool with these settings:
crush-device-class= crush-failure-domain=host crush-root=default
jerasure-per-chunk-alignment=false k=10 m=2 plugin=jerasure
technique=reed_sol_van w=8
and my understanding is if some of the OSDs goes down because of read
error or just flapping due to some reason (mostly read errors , bad
sectors in my case) clients IO shouldn't be disturbed because we have
other object replicas and Ceph sould manage it. But clients IOs are
disturbed, cephfs mount point gets inaccessible on clients even if they
are mounting cephfs against all 3 monitors.
It's not happening always just sometimes. Is it right understanding that
it can happen if read error or flapping occures on active OSD?
Thx!
