We are using two instances of version 8.0 of ceph both on ZFS. We are
frequently getting placement group inconsistent on both Ceph clusters
We are suspecting that there is a problem with the network that is
randomly corrupting the update of placement groups. Does anyone have any
suggestions as to where and how to look for the problem. The network
does not seem to have any problems. ZFS is not reporting any problems
with the disks and the OSD's are fine.
Thanks
Peter.
