This bug was initially created as a copy of Bug #1982721 Description of problem (please be detailed as possible and provide log snippests): In a Multus enabled OCS Internal mode cluster, all commands are not working as expected in toolbox pod. Simple ceph commands works, but rbd commands get hung. ``` sh-4.4# ceph -s cluster: id: 465f536e-3fed-41ec-88c5-00584ad4f069 health: HEALTH_OK services: mon: 3 daemons, quorum a,b,c (age 6h) mgr: a(active, since 6h) mds: ocs-storagecluster-cephfilesystem:1 {0=ocs-storagecluster-cephfilesystem-a=up:active} 1 up:standby-replay osd: 3 osds: 3 up (since 6h), 3 in (since 6h) rgw: 1 daemon active (ocs.storagecluster.cephobjectstore.a) data: pools: 10 pools, 176 pgs objects: 351 objects, 204 MiB usage: 3.5 GiB used, 1.5 TiB / 1.5 TiB avail pgs: 176 active+clean io: client: 852 B/s rd, 11 KiB/s wr, 1 op/s rd, 1 op/s wr sh-4.4# rbd ls -p ocs-storagecluster-cephblockpool >> hangs & no output after several minutes ``` It was observed that toolbox pod doesn't have Multus related annotaions/interfaces by default. Operator should take care of this automatically and apply proper multus annotations to the toolbox. Version of all relevant components (if applicable): OCP: 4.8.0-0.nightly-2021-07-14-153019 OCS: ocs-operator.v4.8.0-452.ci Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? User won't be able to execute all commands via toolbox Is there any workaround available to the best of your knowledge? Yes, Add annotation to "rook-ceph-tools" deployment similar to what MONs have and set hostNetwork to false. Rate from 1 - 5 the complexity of the scenario you performed that caused this bug (1 - very simple, 5 - very complex)? 1 Can this issue reproducible? Yes Can this issue reproduce from the UI? Yes If this is a regression, please provide more details to justify this: - Steps to Reproduce: 1. Install OCS operator 2. Create Storage Cluster with Multus 3. Use this command to start toolbox pod $ oc patch ocsinitialization ocsinit -n openshift-storage --type json --patch '[{ "op": "replace", "path": "/spec/enableCephTools", "value": true }]' 4. Run a simple rbd command $ rbd ls -p ocs-storagecluster-cephblockpool Actual results: rbd command get hung in toolbox pod Expected results: all ceph & rbd commands should work same with and without multus Additional info:
