Hi,

we have observed that in some situations ( probably network glitches )
the pnfs client blacklisted one of the data servers:

NFS: data server 83a95099 connection error -12. Deviceid [22000000000]
marked out of use.

As a result, data server can't be used by this client anymore.

Is there a way to let client to forget about data server?
Some magic in /proc ?

This is SL6.2 (RHEL 6.2):
# uname -a
Linux p3-wgs13 2.6.32-220.2.1.el6.x86_64 #1 SMP Thu Dec 22 11:15:52
CST 2011 x86_64 x86_64 x86_64 GNU/Linux

Regards,
   Tigran.
