I’m not sure, but this seems to have a whiff of a problem we had a while back, wherewe forgot to make appropriate holes in the firewall. GPFS died after the node had beenup successfully for a while. It worked because connection initiated from the host to theGPFS servers, but traffic back to the node was blocked after the session was dropped fromthe firewall table of active connections.On Jul 13, 2018, at 5:06 AM, Javier Ron <j....@qmul.ac.uk> wrote:
Hello,It sounds like an NFS thing, you could try different options for the mount

Subject: [xcat-user] statelite crashes with nfs server timeout------------------------------------------------------------------------------Good afternoon all,
I've got some Centos 7.5 statelite nodes which seem to be booting properly, but after being up for less than a day, they crash with what look like nfs timeouts. The server is up, and if I rpower reset the nodes, they come back up with no problem, but then they crash again overnight.
this may not be an xcat problem at all, it may be an nfs issue, but I thought I'd toss it out here and see if it rang any bells for anyone,
Jeff Berry, MRC CBSU
