GPFS share via linux archiving files rules

hi,

i was working with an end customer on archiving for linux.

we have established they are not able to replace Files with stubs as there as is not supported on rhel 7.9.

so we are trying to delete the files ones archived.

but the we are noticing that for NFS and CIFS you would have to use a Pseudo client for this to be able to archive.

now it is a share But formatted to GPFS so i does not state this needs to have Pseudo client for this.

are we able to archive on GPFS formatted share?

do we need to do it via a Pseudo client like cifs or NFS?

is there a specific document for this?

could you also clarify why stubbing is not possible RHEL 7.9, as it is the only one missing?

thank you in advance!
