 Description   

the hostname convention is define here:

https://github.com/Subaru-PFS/ics_doc/tree/master/SoftwareStudyNote/SSN-00028

We like to modify the hostname convention to match with the current names and to define more meaningful names

we could use

software-nfs for mhs software share

data-nfs for data share

I strongly agree with adding meaningful aliases.

Comment by yuki.moritani [ 15/May/20 ]

I also agree to the idea.
Specifically you are suggesting to change as follows?

  • nfso-ics -> software-nfs
  • nfsp-ics  -> data-nfs
Comment by cloomis [ 05/Jun/20 ]

That works for the hosts, but I'm not convinced that will make fstabs universal because of the server export points. Subaru uses /datapool/proddata and /datapool/software. I think I can change JHU to match, but can LAM?

Comment by fmadec [ 05/Jun/20 ]

unfortunately that seems not possible at LAM

so that's right that we will have to update fstab, but having the same host is maybe useful anyway ?

I see... so I'm afraid this assumption is not so good...

NFS service is assumed to be capable reorganizing into separated hosts. Adding individual target hostname for each target (directory) is assumed, as listed below:

Probably we could use just nfs-ics (and digit for S/N) as a base line, and add feature if you need to separate NFS server for each component (e,g, nfs-software-ics, nfs-data-ics). 

The summit server seem to use nfsv-ics, so it may be confusing to delete this section completely now..
