Hi, while playing around with the old (not builtin) startup method of slave tasks involving the SGE delivered version of `rsh` which allows the setting of a port and has the access rights -rws--x--x (in $SGE_ROOT/utilbin/lx24-amd64) I got "permission denied" on a NFSv4 mount on a node in the cluster. Falling back to NFSv3 during the mount on the node without changing anything else worked as expected.
First I thought it's because of the SUID, but it turned out to be working again when adding r for group and other. So the question is: does NFSv4 need the files to be readable and it's just not implemented to serve executable only files? The only thing I found on the net was, that for a local access there is a difference between a pagein and a read of a file. As NFSv3 can't distinguish these different access modes it grants access in any case ignoring the differences. Can NFSv4 be setup to behave the same way again? -- Reuti _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
