[gpfsug-discuss] Spectrum Scale CES and remote file system mounts

[Simon Thompson (IT Research Support)]

You have been able to do this for some time, though I think it's only just supported.

We've been exporting remote mounts since CES was added.

At some point we've had two storage clusters supplying data and at least 3 remote file-systems exported over NFS and SMB.

One thing to watch, be careful if your CES root is on a remote fs, as if that goes away, so do all CES exports. We do have CES root on a remote fs and it works, just be aware...

Hello All,

I read from the below link, that it is now possible to export remote mounts over NFS/SMB.

https://www.ibm.com/support/knowledgecenter/en/STXKQY_5.0.0/com.ibm.spectrum.scale.v5r00.doc/bl1adv_protocoloverremoteclu.htm

I am thinking of using a single CES protocol cluster, with remote mounts from 3 storage clusters.
May i know, if i will be able to export the 3 remote mounts(from 3 storage clusters) over NFS/SMB from a single CES protocol cluster?

Because according to the limitations as mentioned in the below link:

https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.0/com.ibm.spectrum.scale.v5r00.doc/bl1adv_limitationofprotocolonRMT.htm

It says “You can configure one storage cluster and up to five protocol clusters (current limit).”

Lohit
