If you install an updated version of the multipath driver package, the package manager will automatically uninstall the previous version and then load the new version. For OpenSUSE, a reboot will be required after this.
However, with Ubuntu, ‘ramfs’ can be used to reload the running kernel image. For example:
# sudo update-initramfs -u -k `uname -r`
Perform a reload to confirm the service is running correctly. For example:
# dellnfs-ctl reload
dellnfs-ctl: stopping service rpcbind.socket
dellnfs-ctl: umounting fs /run/rpc_pipefs
dellnfs-ctl: unloading kmod nfsv3
dellnfs-ctl: unloading kmod nfs
dellnfs-ctl: unloading kmod nfs_acl
dellnfs-ctl: unloading kmod lockd
dellnfs-ctl: unloading kmod compat_nfs_ssc
dellnfs-ctl: unloading kmod rpcrdma
dellnfs-ctl: unloading kmod sunrpc
dellnfs-ctl: loading kmod sunrpc
dellnfs-ctl: loading kmod rpcrdma
dellnfs-ctl: loading kmod compat_nfs_ssc
dellnfs-ctl: loading kmod lockd
dellnfs-ctl: loading kmod nfs_acl
dellnfs-ctl: loading kmod nfs
dellnfs-ctl: loading kmod nfsv3
dellnfs-ctl: mounting fs /run/rpc_pipefs
dellnfs-ctl: starting service rpcbind.socket
dellnfs-ctl: starting service rpcbind
Note that there are no upgrade or patching systems available for the ‘dellnfs’ multipath driver module. If a Linux client’s kernel version is updated, the module must be rebuilt or a matching package reinstalled. Similarly, if there is an update to the ‘dellnfs’ package, the module must be reinstalled.
