Yesterday I found that 3 OSDs were down and out with 89% space utilization.

Kernel is root@ed-ds-c178:[~]:$ uname -r 4.7.0-1.el7.wg.x86_64 What else can I do to rectify that situation? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
