With my patch that simulates wide-striping induced resends ( http://review.whamcloud.com/11842 ), it seems that SO is totally broken for such a scenario. sanity.sh test 132 dies with assertion right on mount with SOM enabled: kernel:[113171.017853] LustreError: 30895:0:(mdt_open.c:449:mdt_ioepoch_close()) ASSERTION( info->mti_ioepoch == ((void *)0) || info->mti_ioepoch->ioepoch == o->mot_ioepoch ) failed I poked in the core file a bit and I see that info->mti_ioepoch->ioepoch is 0 and o->mot_ioepoch is 1. |
