Configuration SMB Monitors

Hi, We are looking to load balance CIFS servers using the F5 - the idea is we have two servers, a primary and a secondary. I'd like to only use the secondary when the primary fails (using priority gr...

    It seems as though the issue was due to a missing directory. The message below which was seen in the logs was due to the local directory not being present.

    file.txt was not transferred: No such file or directory

    The monitoring uses /var/run/monitors as a default directory. This appears to be hardcoded. The get commands are successful and the files are being placed in /var/run as indicated by the preceding lines in the logs.

    smbclient //longweb03sandbo/share mypassword -I 10.200.8.28 -p 445 -c cd .; cd; get file.txt file.txt.18261 -U myuser

getting file \file.txt of size 2 as file.txt.18261 (0.5 kb/s) (average 0.5 kb/s)
Recvd: 'Current directory is \

    Creating /var/run/monitors directory resolved the issue. We now get:

    smbclient //longweb03sandbox/share mypassword -I 10.200.8.28 -p 445 -c cd .; cd; get damian.txt damian.txt.24691 -U 101135

I've done that, and it looks like the file is being returned to the Monitor:
