Description

Our BG/P I/O Nodes (IONs, ppc32), which are lustre clients are hitting the following assertions now that they are talking to 2.1 servers:

mdc_fid.c:110:seq_client_rpc()) cli-srv-ls2-MDT0000-mdc-c1298800: Invalid range received from server:[0xffe959f603000000 - 0x00ea59f603000000)
mdc_fid.c:154:seq_client_alloc_seq()) cli-srv-ls2-MDT0000-mdc-c1298800: Can't allocate new meta-sequence, rc -22
mdc_fid.c:193:seq_client_alloc_seq()) cli-srv-ls2-MDT0000-mdc-c1298800: Can't allocate new sequence, rc -22
mdc_locks.c:614:mdc_enqueue()) fid allocation result: -22
mdc_fix.c:148:seq_cleint_alloc_seq()) ASSERTION(range_is_sane(&seq->lcs_space)) failed

I had to transpose that by hand, so please forgive any typos. But I tried to get the range on the first line correct, because it looks fishy at first glance.

This is high priority, because a major user of our BG/P system is dead in the water until this is fixed.
