[HTCondor-users] UNC path in initialdir broken?

[Jason Liu <jason.liu@xxxxxxxxxxxxx>]

Hi,

I have a job description file which has these settings:

log           = BusyThreads.$(Cluster).$(Process).log

output   = BusyThreads.$(Cluster).$(Process).stdout

Error = BusyThreads.$(Cluster).$(Process).stderr

Initialdir = C:\condor\usr\scratch

This works fine. All files (.log, .stdout, .stderr) are written correctly to C:\condor\usr\scratch.

Then I changed initialdir to an UNC path:

initialdir = \\QNAP-STORAGE\Data\JasonL\htcondor\scratch

Then the .log is OK, but .stdout and .stderr are both created but have 0 byte. The .log shows the following error:

007 (054.000.000) 03/23 11:45:40 Shadow exception!

Error from slot1@S3C-MASTER1: STARTER at 192.168.46.11 failed to send file(s) to <192.168.46.22:52247>; SHADOW at 192.168.46.22 failed to write to file \\QNAP-STORAGE\Data\JasonL\htcondor\scratch\BusyThreads.54.0.stdout: (errno 22) Invalid argument

195  -  Run Bytes Sent By Job

353  -  Run Bytes Received By Job

Then I mapped the UNC path \\QNAP-STORAGE\Data to Y: drive, but to no avail. Basically the same error:

initialdir = Y:\JasonL\htcondor\scratch

The .log is still OK, but .stdout and .stderr are both created but have 0 byte. The .log shows the following error:

007 (055.000.000) 03/23 11:53:22 Shadow exception!

Error from slot1@S3C-MASTER1: STARTER at 192.168.46.11 failed to send file(s) to <192.168.46.22:52295>; SHADOW at 192.168.46.22 failed to write to file \\QNAP-STORAGE\Data\JasonL\htcondor\scratch\BusyThreads.55.0.stdout: (errno 22) Invalid argument

195  -  Run Bytes Sent By Job

353  -  Run Bytes Received By Job

It looks like htcondor has unmapped my Y: drive back to UNC path.

Iâve tried various other things, including:

1. Creating a symbolic link to \\QNAP-STORAGE\Data\JasonL\htcondor\scratch and mapping it to C:\condor\usr\link (using mklink /D). The error in the .log file is gone, but the .stdout and .stderr still have 0 bytes.
2. Use file://QNAP-STORAGE/Data/JasonL/htcondor/scratch, this causes htcondor to append the entire initialdir string to the current user directory and reports a directory not found error.

My question: is UNC path not working for initialdir or am I not doing something right?

The fact that .log file is written OK to the correct location means the initialdir must have been parsed correctly. The 0-byte .stdout and .stderr are strange though.

I am running htcondor 8.4.4 on Windows Server 2008 R2.

Thanks

Jason
