Re: [9fans] Out of pseudo mount points

[Adriano Verardo]

Back home today ... I see no subdirs under /mnt/exportfs.
Done. Now both A and B work fine.
Thank you very much Charles !

You need /mnt/exportfs with a set of numbered directories in it, which 
might be missing on A:


% ls /mnt/exportfs
/mnt/exportfs/0
/mnt/exportfs/1
/mnt/exportfs/10
/mnt/exportfs/11
/mnt/exportfs/12
/mnt/exportfs/13
/mnt/exportfs/14
/mnt/exportfs/15
/mnt/exportfs/16
/mnt/exportfs/2
/mnt/exportfs/3
/mnt/exportfs/4
/mnt/exportfs/5
/mnt/exportfs/6
/mnt/exportfs/7
/mnt/exportfs/8
/mnt/exportfs/9

The same for all file servers imported from A.

Where is/could be  the (my, sure) error ?
Can someone kindly help me ?

can this be addressed with a a reboot?

No

if so, then i'd
recommend making Npsmpt larger in exportfs,

it's wired to 32!

  otherwise
there's a bug in exportfs that's leaking pseudo mount points.

The same exportfs runs on A and B.
B->A woks, A->B doesnt.
Probably there is something wrong on A, not in exportfs.
Not a "true" bug but a not-well-managed (because very-very strange) 
external event/condition.


I'll investigate with some print() in the code, I don't know how to use 
acid on an exportfs started by listen.
