Description
The issue can be reproduced by the following steps:
(1）ceph version: 14.2.10, multimds , multiple clients mount the same directory through ceph-fuse
(2) Use vdbench tool test performace, the test script is：
> hd=default,vdbench=/root/vdbench50406,user=root,shell=ssh > hd=hd1,system=192.168.8.101,clients=5 > hd=hd2,system=192.168.8.104,clients=5 > hd=hd3,system=192.168.8.103,clients=5 > fsd=fsd1,anchor=/mnt/dir2,depth=2,width=100,files=10,sizes=4k,shared=yes > fwd=format,threads=32,xfersize=4k > fwd=default,rdpct=60,xfersize=4k,fileio=sequential,fileselect=sequential,threads=32 > fwd=fwd1,fsd=fsd*, host=hd1 > fwd=fwd2,fsd=fsd*, host=hd2 > fwd=fwd3,fsd=fsd*, host=hd3 > rd=rd1,fwd=fwd*,fwdrate=max,format=restart,elapsed=300,interval=1
(3) vdbench tool abort because mkdir failure
