VPhot out of disk space

Hello,

I have tried to save analyses on multiple images tonight, and continue to get an out of disk space error...?

Thanks,

VPhot needs attention from software engineering

This is sad. So many operational issues lately. It is a great application, popular and heavily used. We really need to have the code looked at from the point of view of reliability and error handling. What comes to my mind first, is more exception handling with "try ... catch ..." statements, if it is written in C++ or Java(?), for example.

I just deleted 1/2 my files....not many (20x6.7Mb files). I decided to use my desktop for photometric processing and only use VPhot to derrive my instrumental magnitudes for NGC7790 and M67 standard fields for transformations.  It works like a champ for this!  I'll need Vphot again when I get my CDK17 back from re-aluminizing with my new 10-slot filter wheel;  filter wheel has a different optical window.

I was afraid I was the only one having this problem

I see others have had this problem, too. It is reassuring that I'm not the only one, but I'm sad Vphot is not meeting the expectations we've had for it. I'm sure Geir is working on this problem if it falls on his shoulders. If it is someone else's, I hope they are addressing it.

Has any one heard from AAVSO HQ on this?

VPhot Disk Issues

Folks:

Thanks for this feedback! I have investigated the issue and found disk space wanting on drive d:. I've worked with Geir and gotten 4.5GB of space freed up. We may be performing a "disk switch" tonight to gain even more space and this will be transparent to you, the user.

I will contine to follow up on this tomorrow and make sure that our disk space on VPhot is balanced as needed.

Thank you all!

4 GB may not be enough!

Thanks, Doc!

I find that 4 GB will only hold about 300 of my zipped images from the largest format camera I use. I can shoot that many images in 3 nights, easy. I'd suggest 4 TB!

Relieved, Lew

VPhot Disk Issues

Hi Doc,

whatever magic you and Geir did worked for me. Tonight I was able to download all the BSM images I've been having trouble with for the last few days. Great work yet again. Cheers,

Mark

It dood it agin!

Already out of disk space ...

The physical switch can't happen soon enough!

VPhot Disk Update

Folks:

Just to keep everyone in the loop, early this morning Geir was able to "switch disks" so we are now working on a disk that has over 300GB of space free on it. This will solve our space problem for a good bit of time, and this is how the system was designed to run.

That being said, we appreciate at HQ how much Geir's program has become an important part of the AAVSO's offerings. We also realize that both this type of use and images sizes in general will only get larger as time goes on.

I appreciate the emails I've gotten offering help of whatever kind for this important project. Again, AAVSO members show they are part of one of the greatest communities in science. We'll keep these in mind as we chart the progress of VPhot forward.

Thank you all, and please continue to let us know, as you have done, if something is not working along these lines.
