Bug #847
open
processes getting stuck on mount point
Description
Hey,
I just experienced the infamous ``cache_lock: blocked on 0xd591d418 ""'' message. Checking why the process got stuck revealed that the lock is actually being held by another process which is in the process of doing a lstat(2) on /mnt, a nfs mount which server went away. The stuck process is doing the same, fwiw.
So here it is not a namecache bug, but rather an artifact of nfs being stuck. Anoying nevertheless. Anybody have a clue how to fix that? Yea, mount with -intr. Why don't we do that per default?
cheers

I actually think changing the default to 'intr' is a good idea.-Matt

Matt,
intr is not the default for NFS mounts. Do we want this yet?

Hi,
Attached a (draft) patch for mounting NFS with 'intr' by default.

Hi guys,
Do we all agree we should switch to intr by default?

I use intr on all my boxes and don't see why one wouldn't.
But there might be issues I don't know of, so more feedback is appreciated.
