為了讓虛擬機訪問正常，先將存儲池的min_size調整為1

ceph osd pool set ssd min_size 1

查看存儲池，找出unfound狀態

查看存儲池狀態
ceph osd pool stats ssd
查看歸置組不響應的pg
ceph pg dump_stuck stale
ceph pg dump_stuck inactive
ceph pg dump_stuck unclean
might_have_unfound的osd有以下四種狀態
already probed
querying
OSD is down
not queried (yet)

查看pg恢復狀態

 ceph pg 4.210 query

處理pg unfound

兩種解決方案，回退舊版或者直接刪除
# ceph pg 4.210 mark_unfound_lost revert
Error EINVAL: pg has 1 unfound objects but we haven't probed all sources,not marking lost
# ceph pg 4.210 mark_unfound_lost delete
Error EINVAL: pg has 1 unfound objects but we haven't probed all sources,not marking lost

恢復存儲池min_size

# ceph osd pool set ssd min_size 2
set pool 4 min_size to 2
