Node pod reverse DNS.

Question

Hi. Have a new issue. The first was solved by creating a correct secret. Now my controller pods star and get Ready, but the node pods go in to CrashLoop complaining on not able to do reverse DNS lookup. time='2021-03-30T06:44:31Z' level=debug msg='/csi.v1.Identity/GetPluginInfo: REP 0391: Name=csi-isilon.dellemc.com, VendorVersion=1.5.0, Manifest=map[commit:964a54c79653516cbbb79fcd9a24ec8c1b3abfc7 formed:Mon, 22 Mar 2021 06:38:35 UTC semver:1.5.0 url:http://github.com/dell/csi-isilon], XXX_NoUnkeyedLiteral={}, XXX_sizecache=0'handleServer method: /csi.v1.Node/NodeGetInfotime='2021-03-30T06:44:32Z' level=debug msg='/csi.v1.Node/NodeGetInfo: REQ 0392: XXX_NoUnkeyedLiteral={}, XXX_sizecache=0'time='2021-03-30T06:44:32Z' level=error runid=392 msg='error getting FQDN: 'lookup 54.68.4.10.in-addr.arpa. on 10.4.68.54:53: no such host'' file='/go/src/common/utils/utils.go:266'time='2021-03-30T06:44:32Z' level=debug runid=392 msg='Node ID of worker node is ''' file='/go/src/service/node.go:298'time='2021-03-30T06:44:32Z' level=debug msg='/csi.v1.Node/NodeGetInfo: REP 0392: lookup 54.68.4.10.in-addr.arpa. on 10.4.68.54:53: no such host' Must the reverse maps be configured? -Ulf

The problem is that the deployment with the Dell CSI Operator misses the dnsPolicy: ClusterFirstWithHostNet by default (cf. https://github.com/dell/csi-powerscale/blob/master/helm/csi-isilon/templates/node.yaml#L63).

To fix it you can modify the DaemonSet Isilon-node and add it :
