It looks like I forgot to follow up with the resolution to this problem. The actual workaround was to add “< /dev/console” to the command line.
/usr/lpp/mmfs/bin/mmsdrrestore -p ut003 -R /usr/bin/scp < /dev/console The problem seems to be that under RHEL7, the postscripts do not have a /dev/tty and stdin is not a tty. I did not check under CentOS 6, but presume it had worked (and still works) that way because the scripts had always been run under a pseudoterminal. If the cluster is set up with central mode ssh authentication, the xcat code refuses to attempt an operation that might require typing a password if there is no tty …. Hope this is useful. — ddj Dave Johnson Brown University > On Feb 8, 2017, at 5:39 PM, Christopher Samuel <sam...@unimelb.edu.au> wrote: > > On 07/02/17 22:35, David D Johnson wrote: > >> Now the problem of the day is fixing the SSH credentials so that all >> the diskless nodes booting off the new frontend can get root access >> to all the nodes still booted off the old frontend.
