Re: [HTCondor-users] Duplicate mount points for docker jobs

[Marco van Zwetselaar <zwets@xxxxxxxxxx>]

Dear all,

I remember seeing this happen in the past (v9.5.0?) whenever the execute 
node was the same as the submit node (and with non-shared filesystem). 
Workaround then was to make sure the submit node wasn't the docker 
execute node.

I didn't have the time then to investigate further, but the problem was 
replicable every time.

Kind regards,
Marco
