I have tried these commands:我试过这些命令:
ceph osd pool set default.rgw.buckets.data pg_num 32
ceph osd pool set default.rgw.buckets.data pgp_num 32
But it didn't help either.但它也没有帮助。 I think pg_num 32 is too small for my OSD count, but not sure if it's safe to set it bigger while health status is err我认为 pg_num 32 对于我的 OSD 计数来说太小了,但不确定在健康状态错误的情况下将其设置得更大是否安全
Your OSD #1 is full.您的 OSD #1 已满。 The disk drive is fairly small and you should probably exchange it with a 100G drive like the other two you have in use.磁盘驱动器相当小,您可能应该将其更换为 100G 驱动器,就像您使用的其他两个驱动器一样。 To remedy the situation have a look at the Ceph control commands .要纠正这种情况,请查看Ceph 控制命令。
The command ceph osd reweight-by-utilization
will adjust the weight for overused OSDs and trigger rebalance of PGs.命令ceph osd reweight-by-utilization
将调整过度使用的 OSD 的权重并触发 PG 的重新平衡。 See also this blog post describing this situation.另请参阅此博客文章描述这种情况。
