Description
This issue was initially from Zheng Yan, and locally I have reproduced it by running for 5 hours:
Steps:
1, enable async create/unlink ops by specifying the `-o nowsync` when mounting
2, in one bash terminal run:
# for i in {0..1000}; do pkill -9 ceph-mds; sleep 30; ./bin/ceph-mds -i a -c /data/ceph/build/ceph.conf; sleep 20; done
3, in another bash terminal run:
# for i in {0..1000}; do for i in {0..10}; do mkdir /mnt/cephfs/dir_$i; touch /mnt/cephfs/dir_$i/$i; touch /mnt/cephfs/dir_$i/$i_1; echo "create /mnt/cephfs/dir_$i/$i"; done; sleep 2; for i in {0..10}; do rm -rf /mnt/cephfs/dir_$i; echo "unlinking /mnt/cephfs/dir_$i"; done; done
