Recommendations and limitations for Cloud Scale deployment
This section provides the list of recommendations and limitations for Cloud Scale to be noted.
Ensure that NetBackup clients or media servers outside AKS/EKS cluster are DNS resolvable with NetBackup Primary server load balancer FQDN:
For AKS: For the DNS name, you can add DNS entries in Private DNS.
For EKS: For the DNS name, you can use the Private IP DNS name amazon provided, or you can create DNS and Reverse DNS entries under Route53.
Ensure that you do not use primary server as a media server for use cases where data movement is required.
To use a cloud bucket as storage, it is recommended to create a new DiskPool with the cloud volume or bucket configured under the
msdpscaleoutstorage server.

With NetBackup 10.5 or later, fluentbit DaemonSet's collect every pod's
stdout/stderrlogs for the nodes that the DaemonSets are scheduled on. However due to scheduling, some nodes would not get a DaemonSet pod on it due to the scheduling criteria (of having a major NetBackup pod on it). These pods on nodes without a schedule DaemonSet will not have their logs collected. These logs are non-crucial logs (but important to be aware of) such as infrastructure logs that you encounter in different configurations. However those logs are still available via standard Kubernetes log commands.:
Following are the sample occasional logs that are commonly viewed on the fluentbit collector pod:
[error] [input:forward:forward.0] could not accept new connection [error] [tls] error: unexpected EOF [error] [input:forward:forward.0] could not accept new connection [error] [tls] error: unexpected EOF [error] [input:forward:forward.0] could not accept new connection [error] [tls] error: unexpected EOF And this: [error] [/src/fluent-bit/src/tls/openssl.c:433 errno=104] Connection reset by peer [error] [tls] syscall error: error:00000005:lib(0):func(0):DH lib [error] [/src/fluent-bit/src/tls/openssl.c:433 errno=104] Connection reset by peer [error] [tls] syscall error: error:00000005:lib(0):func(0):DH lib [error] [/src/fluent-bit/src/tls/openssl.c:433 errno=104] Connection reset by peer [error] [tls] syscall error: error:00000005:lib(0):func(0):DH lib

Following are the sample occasional error messages that appear on startup of the fluentbit DaemonSet's and sidecars:
[warn] [net] getaddrinfo(host='nb-fluentbit-collector-svc', err=4): Domain name not found [warn] [net] getaddrinfo(host='nb-fluentbit-collector-svc', err=4): Domain name not found [error] [output:forward:forward.0] no upstream connections available [error] [output:forward:forward.0] no upstream connections available
The above error messages are due to collector having networking issues or not being fully up and accepting connections yet. These messages can be ignored if they are brief and not continuous.
