[gpfsug-discuss] RFE upvote request for "Change NSD Name" RFE

[Bryan Banister]

Just for clarification, this RFE is for changing the name of the Network Shared Disk device used to store data for file systems, not a NSD I/O server node name,

+1 from me.
Someone did a building block install for us and named a couple io nodes with initial upper case (unlike all other unix hostnames in our env which are all lowercase). For a while it just bothered us, and we complained occasionally to hear that it was not easy to change. Over two years after install a case-sensitive bug in call home hit us on those two io nodes.

Best,
Chris

Hey all…

Hope all your clusters are up and performing well…

Got a new RFE (I searched and didn’t find anything like it) for your consideration.  The ability to change the name of an existing NSD:
http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=147125<https://urldefense.com/v3/__http:/www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=147125__;!!C6sPl7C9qQ!A9Xxl1aqkzhreSk41q7vR7GAgo-Dq3KsEpHcGfx8t_I15bCq7T0l5UyHAL7p6nLq$>

We embed information into the NSD name, which sometimes needs to be updated.  However there isn’t a way to simply change the NSD name.  You can update the NSD ServerList, but not the name.  You can remove the NSD from a file system, delete it, then recreate with a new name and add it back into the file system, but there are obvious risks and serious space and performance impacts to production file systems when performing these operations.

Thanks!
