slightly odd interface name IMO, as it's a bit more of a "get storage config from
volid", so adapt the method name in that direction, e.g.:
# extract the storage ID from a volume ID and returns it config or undef if storage could not be
# found (i.e., got removed)
sub storage_config_from_volid {
> + my ($cfg, $volid) = @_;

couldn't we avoid the useless intermediate variable and directly
return storage_config($cfg, $storeid, 1);
At which point the question arises if we really want a common helper "just" for this,
no hard feelings against, but is IMO a bit close to thinking that not much would be
lost in terms of code beauty or maintenance if we'd just program those two lines out
on the few call sites.
