But it wasn't as easy as just running repair. With default bhash OOM killed repair in ~1/3 of phase6 (128GB of ram + 50GB of ssd swap). bhash=256000 worked. Sometimes segfault happens but I don't have any stack trace unfortunately and trying to reproduce on my other test machine gave me no luck. One time I got: xfs_repair: workqueue.c:142: workqueue_add: Assertion `wq->item_count == 0' failed. -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )
