DSS Temp Storage

[TheMan]

I recently found out about the amazing drizzle feature in DSS. So I bought a 3tb hard drive for the temp storage and later for photo storage. But even with 2.7tb of space for temp files it isn't enough for the stacking process. Is there a way to use 2 different storage devices for the DSS temp files?

How much data are you stacking? My working drives are 128gb and I haven't hit any limits with temp storage, even with drizzle and 300+ subs and 3x drizzle.

I have over 1200+ images...

45 second subs with a dslr in bortle 9 skies isn't the best combination.

So as raw files thats about 30gb? Even if you used 4 times that for drizzle you are well under 3000gb.

Is the temp directory saved in DSS settings?

 

[TheMan]

yes I did change that to the the temp file storage to the external hard drive. I can successfully register the images, but the stacking process needs more temporary space.

The only thing I can think of is if you have intermediate files turned on that would create alot of files each stacking attempt.

But to be honest even with that turned on you shouldn't be running out of space. What specific error are you getting when stacking?

[TheMan]

It doesn't show an error, but when stacking begins it says I do not have enough space. If I continue it shows it'll take an absurdly to finish processing. (70 hrs)

How much free space do you have on your main windows drive? Its possible I guess that its still using that for some sort of swap space.

DSS can be finicky, and usually a re-install sorts it out - but other than the above im out of ideas.

If the error is referring to memory, rather than space, it might be complaining about not having enough RAM. It seems odd that it would allow you to continue processing the image if it has worked out that there isn't enough space so im thinking this may be the actual problem. It would also account for the long processing time.

Well thanks anyway, i'll try looking through some settings and re-installing. But I doubt DSS would be asking for 2500+ gb of RAM.

Yeah its not going to need that much, but it might need more than say 2gb for a job like that with drizzle. It could do it with less, but that's where the delay comes into it - constantly loading files between storage and ram is time consuming. If your new drive is external there may also be a delay in transferring the data over USB etc. When I hook up my usb drive it really slows down the stacking process.

Stacking 300 subs on my system with drizzle, using Flash storage and 16gb ram takes just under an hour and a half.
