Can't create channel directory: '/apps/nfsen/profiles-data/live/abc-test' File exists

[ozbillwang]

my environment is RHEL 9 with nfsen 1.3.8, perl v5.32.1

when run nfsen start with default nfsen.conf , it is fine. But when add new source, got error:

RRD DB 'abc3.rrd' already exists!
RRD DB 'abc2.rrd' already exists!
Use existing profile info for profile 'live'

New sources to configure : abc-test
Continue? [y/n] y

Add source 'abc-test'Error while setting up channel 'abc-test': Can't create channel directory: '/apps/nfsen/profiles-data/live/abc-test' File exists
No collector started!

Reconfig done!
Setup done.

After troubleshooting, I found , even I manually deleted the folder "/apps/nfsen/profiles-data/live/abc-test" , when the install.pl ask for

New sources to configure : abc-test
Continue? [y/n] 

the folder has been created in the backend. Not sure which perl module did that, the only one is

# grep -ri 'New sources to configure' *
libexec/Nfsources.pm:	print "New sources to configure : ", join(' ', @AddSourceList), "\n" if scalar @AddSourceList;

But there is no line to create new folder in it.

I did a fix directly in libexec/NfProfile.pm

change from

mkdir "$dir

to

mkdir "$dir" unless -d $dir or

it works now.
