我有一个小的Ceph集群。它的设置方式如下所述：
https://www.theo-andreou.org/?p=1750
在部署节点（托管ntp服务器的地方）上重启后，我得到：
ceph health; ceph osd tree
HEALTH_ERR 370 pgs are stuck inactive for more than 300 seconds; 370 pgs stale; 370 pgs stuck stale; too many PGs per OSD (307 > max 300)

节点已启动并且ssh可访问。有没有办法让系统恢复健康？
答案 0 :(得分：1)
显然，OSD守护程序已关闭（即使在报告为“向上”的节点上）。运行I=0; for ID in {02..10} {12..14} {16..23}; do ceph-deploy osd activate node${ID}:/var/local/osd${I}; I=$((${I}+1)); done后，我现在有 HEALTH_OK
非常感谢#ceph IRC频道！
