I think that product was Videocharger, but it used the multimedia file system striped across multiple SCSI-1 disks for streaming video performance IIRC!
Sure we're not talking about Tigershark? 😉 (and can't forget the cousin, PIOFS or Parallel I/O File System) --- Glen Corneau Senior, Power Partner Technical Specialist (PTS-P) IBM Technology, North America Email: [email protected] Cell: 512-420-7988 ________________________________ From: gpfsug-discuss <[email protected]> on behalf of Ryan Novosielski <[email protected]> Sent: Wednesday, March 22, 2023 19:12 To: gpfsug main discussion list <[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, |---------------------------*O*--------------------------- ||_// the State | Ryan Novosielski - novosirj@ rutgers. edu || \\ University | Sr. Technologist - 973/972. 0922 ZjQcmQRYFpfptBannerStart This Message Is From an External Sender This message came from outside your organization.

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 we’d 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?
