Hello Another dump/snapshot problem that seems to have surfaced with NetBSD 8.0: I run a dump with snapshot, and after a while, all processes get stuck in tstile.
This happens with GENERIC kernel, though I added LOCKDEBUG to investigate. Processes backtrace show namei/VOP_LOCK/rw_enter and following the locks owner, it seems everyone is ultimately waiting for ioflush, i which itself is stuck with this backtrace: sleepq_block cv_wait fstrans_start VOP_BWRITE getnewbuf getblk bio_doread bread ffs_update.part.3 ffs_sync VFS_SYNC sched_sync If I understand correctly, that means a n I/O that never completed, right? Anyone has something to test here before I downgrade this machine to 7.1.2? -- Emmanuel Dreyfus m...@netbsd.org
