       kernel:LustreError: 3652:0:(mdt_handler.c:2706:mdt_object_lock0()) ASSERTION( !(ibits & (MDS_INODELOCK_UPDATE | MDS_INODELOCK_PERM)) ) failed: lustre-MDT0001: wrong bit 0x2 for remote obj [0x200000007:0x1:0x0]
 kernel:LustreError: 3652:0:(mdt_handler.c:2706:mdt_object_lock0()) LBUG

      To reproduce the issue two-node cluster is enough.

      On server:

      #MDSCOUNT=3 lustre/tests/llmount.sh
#lctl set_param mdt.*.enable_remote_dir=1
#lctl set_param mdt.*.enable_remote_dir_gid=1122

      Client

      #mount -t lustre 172.16.157.136@tcp0:/lustre /mnt/lustre
#lustre/utils/lfs mkdir -i 1 /mnt/lustre/mdt1

      Server is failed with LBUG above.
