NetBackup PureDisk Appliance 5020/5030 version 1.4.4 may perform sluggishly.

NetBackup PureDisk Appliance 5020/5030 version 1.4.4 may perform sluggishly resulting in poor backup performance or an unresponsive appliance operating system, when callhome executes too many concurrent fsadm commands.


The NetBackup PureDisk Appliance 5020/5030 version 1.4.4 callhome/hardware monitoring feature includes monitoring for filesystem fragmentation using fsadm commands. Callhome runs hardware and software monitoring commands every 15 minutes. In some environments, fsadm fragmentation checks can take longer than 15 minutes to complete leading to an increasing number of concurrent fsadm, callhome and perl processes running which can exhaust appliance cpu and memory resources.

Confirm by reviewing running processes specific to fsadm.
1. Login to CLISH and access a root prompt via: > admin > su

2. Execute:
# ps -ef | grep fsadm | grep -v grep | wc -l

If a value greater than 1 is returned, that means that there is more than one fsadm command executing currently and the Appliance may be potentially affected by this issue.
