- Infrastructure management issues
- Storage-related logs are not written to the designated log files
- Unable to start a node that is shut down
- Arrival or recovery of the volume does not bring the file system back into online state making the file system unusable
- Unable to replace a stopped node
- An NVMe disk is wrongly selected as a target disk while replacing a SAS SSD
- Disk replacement might fail in certain situations
- Replacing an NVMe disk fails with a data movement from source disk to destination disk error
- Unable to detect a faulted disk that is brought online after some time
- When NetBackup Flex Scale is configured, the size of NetBackup logs might exceed the /log partition size
- Nodes may go into an irrecoverable state if shut down and reboot operations are performed using IPMI-based commands
- Add node fails because of memory fragmentation
- Replace node may fail if the new node is not reachable
- NetBackup certificates tab and the External certificates tab in the Certificate management page on the NetBackup UI show different hosts list
- The NetBackup web GUI does not list media or storage hosts in Security > Hosts page
- Media hosts do not appear in the search icon for Recovery host/target host during Nutanix AHV agentless files and folders restore
- On the NetBackup media server, the ECA health check shows the warning, 'hostname missing'
- The backup host pool is not visible while configuring the Dynamic NAS (DNAS) policy on a NetBackup Flex Scale cluster.

NetBackup primary container goes into unhealthy state
It may happen that the NetBackup primary container goes into unhealthy state on its own and the following error message gets displayed:
bashrpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:235: starting container process caused "process_linux.go:110: decoding init error from pipe caused \"read parent: connection reset by peer\""
This also causes the ongoing backup and restore jobs to fail. (APPSOL-148171)
Workaround:
Stop the NetBackup primary container (nb_master) forcefully and wait for few minutes till the master container starts on its own.
# docker stop nb_master
Note:
This needs the involvement of the Veritas Support.
