“mount.nfs4: Operation not permitted” when mounting NFS device

Posted on by

This is a configuration issue. A required parameter needs to be added to the file /etc/exports to define the root file system for mounting.

The parameter that needs to be added follows:

fsid=0

An example line would look like the following:

/storage *(rw,fsid=0,sync,insecure_locks,insecure,no_root_squash)

Additional information

NFSv4 works differently and no longer references the root of the file system but instead requires the root to be defined with fsid=0.

If fsid=0 is not present, permission will never be granted for the file system to be mounted.

via RHEL6: “mount.nfs4: Operation not permitted” when mounting NFS device – IBM System Cluster 1350 (1410).

NFS4 is different.   After configuring exportfs the old fashioned way the nfs mounts did not work at all.  I narrowed it down to the CentOS server running nfs4 and then found this article from IBM.  It seems to work now.

IBM Faces the Perils of “Bring Your Own Device”

Posted on by

The trend toward employee-owned devices isn’t saving IBM any money, says Jeanette Horan, who is IBM’s chief information officer and oversees all the company’s internal use of IT. Instead, she says, it has created new challenges for her department of 5,000 people, because employees’ devices are full of software that IBM doesn’t control.

Horan isn’t only trying to educate IBM workers about computer security. She’s also enforcing better security. Before an employee’s own device can be used to access IBM networks, the IT department configures it so that its memory can be erased remotely if it is lost or stolen. The IT crew also disables public file-transfer programs like Apple’s iCloud; instead, employees use an IBM-hosted version called MyMobileHub. IBM even turns off Siri, the voice-activated personal assistant, on employees’ iPhones. The company worries that the spoken queries, which are uploaded to Apple servers, could ultimately reveal sensitive information.

How To Catch a Criminal With Data

The researchers ultimately turned the department onto a predictive software called SPSS, which had for years been used to crunch data in a host of disciplines not necessarily connected to crime. The department launched a pilot program with it to analyze trends, as part of a strategy of fighting crime by real-time data-mining.

IBM acquired SPSS back in 2009, and did the same late last year with Knisley’s software company, i2. On a computer monitor, Knisley had pulled up a program called COPLINK, which sucks into one massive database all that disjointed information that was once scribbled down by hand.

DB2 – the secret database

Certainly, according to the Winter Corporation’s 2005 survey, the largest OLTP (On-Line Transaction Processing) databases in the world are hosted on DB2. The volume prize goes to the Land Registry at 23.1 TB and the prize for the number of rows goes to UPS – 89.6 billion; both run on DB2.

DB2 has always ruled in the mainframe environment: on that platform it has no peer. In 1996 (ten years ago!) IBM made all the right technical moves to expand the use of DB2 down to the mini and even the PC markets. DB2 was produced in three versions. These have had various names over the years – UDB (Universal DataBase) was often used but it now being gently dropped by IBM. The most useful names I’ve come across are:

• DB2 for z/OS (Mainframe)

• DB2 for iSeries (AS400 as was)

• DB2 for LUW (Linux, UNIX and Windows)

NASA unplugs last mainframe

Posted on by

Of course NASA is just one of the latest high profile mainframe decommissionings. In 2009 The U.S. House of Representatives took its last mainframe offline. At the time Network World wrote: “The last mainframe supposedly enjoyed “quasi-celebrity status” within the House data center, having spent 12 years keeping the House’s inventory control records and financial management data, among other tasks. But it was time for a change, with the House spending $30,000 a year to power the mainframe and another $700,000 each year for maintenance and support.”

Cue violins.
