[zfs-discuss] Investigating a hung system

2011-02-25 Thread Mark Logan

Hi,

I'm investigating a hung system. The machine is running snv_159 and was 
running a full build of Solaris 11. You cannot get any response from the 
console and you cannot ssh in, but it responds to ping.


The output from ::arc shows:
arc_meta_used =  3836 MB
arc_meta_limit=  3836 MB
arc_meta_max  =  3951 MB

Is it normal for arc_meta_used == arc_meta_limit?
Does this explain the hang?

Thanks,
Mark

It means that it has cached as much metadata as it's allowed to during
the current circumstances (arc size).

 Does this explain the hang?

No..
