Re: NFS mount problem between zOS and Linux
I was having some strange issues with my z/OS to linux system and had to
specify vers(3).
MOUNT FILESYSTEM(MYNFS) +
MOUNTPOINT('/mnt') +
parm('10.6.0.10:/srv/ftp/pub,vers(3)') +
TYPE(NFS) MODE(RDWR)

The typical mount syntax involves
hostname:/path/name
whereas you don't have the colon in it.
I don't know what the -o sec=sys does, so I can't comment on that.
In the past, you used to have to compile the mvslogin program to run on
the Linux system that would be doing the mount. That was so the External
Security Manager on z/OS (whether ACF2, RACF, or other) could authenticate
the subsequent request for the mount. I would think that _some_ sort of
authentication would still be needed today.

NFS mount problem between zOS and Linux
Hi all First of all a happy good year. I can not mount a zOS NFS directory from my Linux machine. I searched the web and tried the command examples from the IBM manual but every variation failed. From the Linux machine I can do a showattr of the zOS server if I only supply the zOS host name. The last attempt was the Linux command: mount -t nfs4 -o sec=sys proto=tcp Catweazle-zOS/jedsp /jedsp where Catweazle-zOS is the zOS host name and jedsp are directories on both systems. The EXPORTS file contains: /hfs/jedsp JEdSP Any help would be greatly appreciated.

NFS mount problem between zOS and Linux
Hi all, Thanks Mark for your quick reply. The message after the mount command is the mount help information. JEDSP is a MVS FLQ I changed the EXPORTS dsn to include /hfs/jedsp/web WEB and removed the old jedsp entries. but to avail. I am running Ubuntu 12.04 kernel 3.2.0.57 Can somebody help? I think there is an error in the mount command. Thanks, j@n -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

I think there is an error in the mount command. Thanks, You didn't answer the question about the dir you are trying to export. Is it in the root file system on z/OS? Is the path actually /jedsp or /jedsp/web or something else (like /u/jedsp)? I'm asking because it would be bad practice to create a path / dir in your z/OS root or even sysplex root as opposed to having some other standard / path where you install z/OS unix software. But I see it often anyway.

Re: NFS mount problem between zOS and Linux
Please check your MVS syslog... you should have error messages (especially if your mount command is wrong) that should give you an idea of what the problem is. I missed your initial post ... please also repost your mount command ... Kind Regards.

NFS mount problem between zOS and Linux
Hi all, Mark, I agree that maybe it is a bad practice to touch the root system but in my case the zOS has a /jedsp/web directory because I did not want the pollute the default install directories Underneath /jedsp/web there are directories for pub, cgi, css images. The zOS HTTP server has no problem to find /jedsp/web/pub/index.html Can you or somebody else from the list help?

Re: NFS mount problem between zOS and Linux
Could you issue a 'mount -q /Catweazle-zOS' and re-post ??. Are you sure there are no error messages in the SYSLOG ??. How about RACF messages ??. -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of jan de decker Sent: Thursday, December 26, 2013 11:55 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: NFS mount problem between zOS and Linux Hi all, The mount command I tried last, after several variartions was the example from the IBM manual: mount -t nfs4 -o sec=sys proto=tcp Catweazle-zOS/hfs/jedsp/web /jedsp/web There are no error messages in the zOS log nor in the NFSS STC Hope somebody can help.
