Création de la ressource :

#clresource "create" -g "NomAppli-rg" -t "SUNW.nfs" -v "NomAppli-nfs-rs"
clresource : node2 - Unable to access directory /RepAppl/SUNW.nfs:No such file or directory.
clresource : (C189917) VALIDATE on resource NomAppli-nfs-rs, resource group NomAppli-rg, exited with non-zero exit status.
clresource : (C720144) Validation of resource NomAppli-nfs-rs in resource group NomAppli-rg on node node2 failed.
clresource : (C891200) Failed to create resource "NomAppli-nfs-rs".

==> Cette erreur indique l’oublie de la prise en compte de HAStoragePlus. Le cluster pense qu’on utilise le global FS.

 


Liste les ressources du cluster


root@node1 # clrs list
NomAppli2-lh-oper
NomAppli2-hasp-rs
NomAppli-hasp-rs
NomAppli-oralsnr-rs
NomAppli-orasrv-rs
NomAppli-sapci-rs
NomAppli-cft-rs
NomAppli-sapas-rs
NomAppli-lh-oper


Dans ce cluster la ressoruces NomAppli-hasp-rs est de type HAStoragePlus.
Nous allons maintenant intégrer cette dépendance à la ressource NFS par l’option "-p resource_dependencies="

root@node1 # clresource "create" -g "NomAppli-rg" -t "SUNW.nfs" -p resource_dependencies=NomAppli-hasp-rs "NomAppli-nfs-rs"
clresource : node1 - Some shared paths in file /RepAppl/SUNW.nfs/dfstab.NomAppli-nfs-rs are invalid.
clresource : (C189917) VALIDATE on resource NomAppli-nfs-rs, resource group NomAppli-rg, exited with non-zero exit status.
clresource : (C720144) Validation of resource NomAppli-nfs-rs in resource group NomAppli-rg on node node1 failed.
clresource : (C891200) Failed to create resource "NomAppli-nfs-rs".

==> La création de la ressource n’a toujours pas abouti ...
==> Il faut créer le fichier /RepAppl/SUNW.nfs/dfstab.NomAppli-nfs-rs avant la création de la ressource NFS

root@node1 # vi /RepAppl/SUNW.nfs/dfstab.NomAppli-nfs-rs
share -F nfs -o anon=0 /RepAppl/sapmnt/NomAppli
share -F nfs -o anon=0 /RepAppl/sapmnt/NomAppli/exe_linux
share -F nfs -o anon=0 /RepAppl/NomAppli
share -F nfs -o anon=0 /RepAppl/NomAppli/aci/archivage


root@node1 # clresource "create" -g "NomAppli-rg" -t "SUNW.nfs" -p resource_dependencies=NomAppli-hasp-rs "NomAppli-nfs-rs"


# clrs list
NomAppli2-lh-oper
NomAppli2-hasp-rs
NomAppli-hasp-rs
NomAppli-oralsnr-rs
NomAppli-orasrv-rs
NomAppli-sapci-rs
NomAppli-cft-rs

Synthese :
 

# clrt list
# pkgadd -d . SUNWscnfs
# clrt register -n node1:node2 SUNW.nfs:3.2
# vi /RepAppl/SUNW.nfs/dfstab.NomAppli-nfs-rs
# clresource "create" -g "NomAppli-rg" -t "SUNW.nfs" -p resource_dependencies=NomAppli-hasp-rs "NomAppli-nfs-rs"
