Debug log taken on:
- client helios4502 (10.4.29.248@o2ib)
- MDS helios16 (10.4.72.50@o2ib)
- OSS helios19 (10.4.72.1@o2ib) serving work-OST0003

Problem:
'lfs setstripe -c 1 -o 3 toto'  takes 50 seconds to complete, and finally the OST index 4 (work-OST0004) is assigned to file "toto" instead of OST index 3 (work-OST0003)

MDS reports the following errors after the 50 seconds:
