Re: [SSI-devel] Re: SSI-Lustre-1.2.4 initnode ssi_deadlock_check: cfs_kswapd hung?

[Jaideep D. <Jai...@hp...>]

Roger,
  Did the lines below work? Let me know. I will merge them into the 
patch and put the
new patch up on the website.
   Btw, to answer a previous question, we have always tested Lustre-SSI 
only as a client
so far. This goes for previous versions of lustre too. I think I might 
have tried briefly
using it as  an OST/MDS on previous versions. But definitely not on this 
one. If you are
intending to use it as an OST or MDS, let me know if you run into 
problems and how it goes.
              Jai.
