[LU-12209] cannot create stripe dir: Stale file handle

Description

I'm facing a new issue on Oak (2.10.7 servers), tried with both 2.10 and 2.12 clients:

As root:

# cd /oak/stanford/groups/
# lfs mkdir -i 1 caiwei
lfs mkdir: dirstripe error on 'caiwei': Stale file handle
lfs setdirstripe: cannot create stripe dir 'caiwei': Stale file handle

# lfs getdirstripe .
lmv_stripe_count: 0 lmv_stripe_offset: 0 lmv_hash_type: none

does that ring a bell? Oak is only using DNE v1 with statically striped directories. Never seen that before 2.10.7 (we recently upgraded Oak).

a basic lctl dk doesn't show anything on the MDS but I may have to enable specific debug flags to see more. No other traces found so far.

Tried with 2.10 and 2.12 clients, with or without idmap.

Thanks!
