I had basically /just/ started calling it Spectrum Scale. š So I guess Iām at least partially responsible for the name change.

It used to be called āSpectrum Scaleā but that being abbreviated to āSSā was a problem, hence the recent change. :-) As an appliance it is called ESS = āElastic Storage Systemā since before being called Spectrum Scale, it was briefly called āElastic Storageā All the software RPMs though still start with āgpfsā and that is what every techie person still calls the software. The software unpacks to /usr/lpp/mmfs/bin since the product was once the āMultiMedia FileSystemā The ālppā comes from AIX. It stands for āLicensed Programming Product ā. This term is lost on everyone who comes from a Linux background. Likewise no one from the Linux world know what āadmā is, as in /var/adm/ras (or ras?) There are c. 333 āmmā commands like say āmmdeldiskā. None are actual binaries ā all are Korn shell scripts (Korn was a shell language that Bash eventually replaced) *(actually a few mm commands are written in Python not Korn.) Most mm command call underlying binaries which all start with ātsā eg ātsdeldiskā. This is, as we all know is become the product was known as TigerShark but no one could be bothered renaming stuff when āTigerSharkā as a name was dropped 25 years ago. Simple?

When MMFS was cancelled, all four of its developers of the time joined the GPFS effort, and we had collaborated with them to sequence changes in the same code base for a few years by that point and knew them all well. ________________________________ From: gpfsug-discuss <[email protected]<mailto:[email protected]>> on behalf of Ryan Novosielski <[email protected]<mailto:[email protected]>> Sent: Wednesday, March 22, 2023 8:12 PM To: gpfsug main discussion list <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] Re: [gpfsug-discuss] How to: Show clients actively connected to a given NFS export (CES) The product formerly known as MMFS? -- #BlackLivesMatter ____ || \\UTGERS<file://UTGERS>, |---------------------------*O*--------------------------- ||_// the State | Ryan Novosielski - novosirj@ārutgers.āedu || \\ University | Sr. Technologist - 973/972.ā0922 The product formerly known as MMFS? -- #BlackLivesMatter ____ || \\UTGERS<file://UTGERS>, |---------------------------*O*--------------------------- ||_// the State | Ryan Novosielski - [email protected]<mailto:[email protected]> || \\ University | Sr. Technologist - 973/972.0922 (2x0922) ~*~ RBHS Campus || \\ of NJ | Office of Advanced Research Computing - MSB A555B, Newark `' On Mar 22, 2023, at 17:30, Alec <[email protected]<mailto:[email protected]>> wrote: Thanks for correction.. been using GPFS so long I forgot my basic NFS command. Or that its now IBM Storage Scale and no longer Spectrum Scale or GPFS... As a note that info is a little unreliable, but if you take a daily snapshots and throw it all together it should give you something. Alternatively you can have most nfsd daemons log mounts and then scan the logs for a more reliable method.

This info should not be considered reliable. See the notes on rmtab in rpc.mountd(8). showmount -d could also be an option: -d or --directories List only the directories mounted by some client. Best regards, Markus Thanks, but that shows the export list: a list of shares and the hosts / networks that have access. It does not show which of those clients are currently connected to a given share, as in have it mounted.

We have certain NFS exports that we suspect are no longer used or needed but before removing weād like to first check if any clients are currently mounting them. (Not just what has access to those exports.) Are there commands that will show this?
