I have the exact same problem: I upgraded to 16.2.6 and set bluestore_fsck_quick_fix_on_mount to true, after a rolling restart of my osds only 2 of 5 came back (one of them was only recently added and has only very few data, so in essence there is only 1 osd really running). Al other osds crashed with: > ./src/osd/PG.cc: In function 'static int PG::peek_map_epoch(ObjectStore*, spg_t, epoch_t*)' thread 7f68d999bd00 time 2021-10-30T08:59:11.782259+0200 > ./src/osd/PG.cc: 1009: FAILED ceph_assert(values.size() == 2) > ceph version 16.2.6 (ee28fb57e47e9f88813e24bbf4c14496ca299d31) pacific (stable) My cluster does not come up anymore and I cannot access my data. Any advice on how to recover here? -tmolitor _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
