Thanks for the suggestions.
I've tried both -- setting osd_find_best_info_ignore_history_les = true and restarting all OSDs, as well as 'ceph osd-force-create-pg' -- but both still show incomplete
PG_AVAILABILITY Reduced data availability: 2 pgs inactive, 2 pgs incomplete
pg 18.c is incomplete, acting [32,48,58,40,13,44,61,59,30,27,43,37] (reducing pool ec84-hdd-zm min_size from 8 may help; search ceph.com/docs for 'incomplete')
pg 18.1e is incomplete, acting [50,49,41,58,60,46,52,37,34,63,57,16] (reducing pool ec84-hdd-zm min_size from 8 may help; search ceph.com/docs for 'incomplete')
The OSDs in down_osds_we_would_probe have already been marked lost
When I ran the force-create-pg command, they went to peering for a few seconds, but then went back incomplete.
Updated ceph pg 18.1e query https://pastebin.com/XgZHvJXu
Updated ceph pg 18.c query https://pastebin.com/N7xdQnhX
Any other suggestions?
Thanks again,
Daniel

this should work for PG 18.1e, but not for 18.c. Try running "ceph osd
force-create-pg <pgid>" to reset the PGs instead.
Data will obviously be lost afterwards.
