Description

we hit LBUG in filter_finish_transno() on OSS and OSS got heavy loads, then it went to down, finally. Once rebooted it, then started the recovery, we got same LBUG again. In order to move back into the production, we actually started OST with abort_recov, now it's working well.

I found same bug (DDN hit same bug before and filed) on bugzilla (bug 20394) and it should be fixed in 1.8.6. Our branch lustre-1.8.4.ddn2 which based on 1.8.4, but this patch is included and applied to our branch, already. So, I don't know why got same LBUG in filter_finish_transno(). Please investigate this.
