4/10/2015 1:10:30 PM | ATLAS@home | Aborting task 40GKDmnAi0lnDDn7oo6G73TpABFKDmABFKDmiiLKDmABFKDmhOKPIn_2: exceeded disk limit: 6528.21MB > 4291.53MB


First CMS task ran fine while at the same time I was running Einstein GPU X2,vLHC X2,and Atlas X2

Second CMS task it would only let me run E-GPU X1 and vLHC X2 and Atlas X2

Third CMS task it will only let me run vLHC X2 and Einstein GPU X1

No longer can run any Atlas at the same time.

Never had this happen before.

Is that why not many members did more than one CMS task before they quit?

CMS-dev workunits like to leave their disk images behind, check your slots there's probably one or more with only a .vdi left in them.

If you delete the vdi you should be good to go again.

Why this causes other projects to get that exceeded disk space error even if Boinc has lot's of available space left I don't know but it's very annoying...

Yes I always image *remove* vdi's on all of my hosts since I am a long time T4T/vLHC member and the same with Atlas so I am used to doing that on my 6 hosts.

I only have CMS running on my 8-core and it is my only SSD

Of course I also run all of mine 24/7 and in my preferences have them all set at no limit.

Strange that it worked normal during the first CMS and has got worse the following 2 tasks here.

But then I did not have any problem getting the first 2 tasks here complete and validated.

My first CMS-devs were also ran on a rig using an SSD and I had the same result.

I thought it might be due lack of space on the ssd and so switched CMS over to two other dualie rigs that use hdds.

What was puzzling was it still happened on one of those even though Boinc has 180GB+ of space available.

This rig was also running 2x Atlas, 2x Edge and 8x SRBase wus plus an Einstein on the gpu.

Once I removed the leftover vdi it has been back to zero errors.

The second rig had no leftovers and no disk space error problems.

Both are due to finish their second CMSs tomorrow and it will be interesting to see what happens then.

I also run T4T, vLHC and Atlas and haven't had this particular problem with them.

I just find it weird that the CMS wus seem to keep running fine but yet cause problems for wus from other projects...

Hello, New Member too.
My 1st job failed as well. and a bunch of Sixtrack and SETI bombed out with Disk Usage Exceeded error too.
Job No2 is running so far...

The VDI has grown to over 4Gb, and in the VM the loadav has grown to about 8, with each task now taking over 30 mins.

In fact the VM has now stalled using 1 CPU core to 100%, the console shows a frozen TOP and Apache wont connect.

14 errors for me on this host since joining CMS-dev a couple of days ago.
Sixtrack wu fails with LHC@home 1.0 | Aborting task.....exceeded disk limit: 6860.42MB > 572.20MB before it gets a chance to start.

CMS itself appears to run fine and I'm not seeing any debris left behind after it finishes.

Don't know how or why there should be this interaction but others have reported similar here, and further down this thread.

No interference with vLHC VM but I'm only allowing 1 of them to run just now while there's Sixtrack work available.
Currently running:
1 x CMS
1 x vLHC
2 x Sixtrack

8GB RAM with another 4GB allocated on a ReadyBoost USB stick.
Boinc 7.4.42

Follow-up on my sixtrack exceeded-space errors below:
I have noticed that when CMS finishes, it doesn't quite do a full cleanup and leaves a disk image .vdi in the slot. I guess that Sixtrack tries to use that slot, thinking it is empty but finds the .vdi which pushes it over the permitted size, causing the error.
I have reset LHC 1.0 just in case anything else may have become corrupted but I'll need to wait for the next batch of work to see if that fixes it. Until a fix can be found I'll only let CMS and sixtrack run when the other isn't and will delete the relevant slot to clear the debris when required.

A 'private drop' (bare BOINC client, no installer, place in existing BOINC program directory) has been made available for people willing to test this. I believe it will also have the extra <slot_debug> logging that David mentioned.

x64:
http://boinc.berkeley.edu/dl/boinc.040515.x64.zip

If you use it, please enable the extra logging and report back (whether success or failure) - we're looking for proper deletion of the .vdi file in all cases.

That seems normal - I'm seeing init_data.xml being removed and replaced regularly with earlier versions too. The interesting thing will be to compare the list of files deleted at the end of the run, between the earlier versions (which I will post - later today) and this private drop version - and to compare both with what happens in the slot directory, of course.

Btw: I'm running vboxwrapper 26166 in stead of the stock application 26165 and have set in the vbox job xml the flags
<enable_vm_savestate_usage/>
<disable_automatic_checkpoints/>


However I made 1 snapshot myself between switching BOINC releases.
I've seen with vLHC that those manual snapshots are properly cleared when the task finishes.

Upgraded to 7.5.1 and set the slots flag and get similar output to Richard with all files deleted as they should. (As soon as you take your car to a mechanic, the rattle stops!)

Maybe something else has changed between 7.4.42 and 7.5.1 which has unintentionally fixed the slot clean-out error?

Task on the other machine is due to finish in an hour or so, so I'll watch it finish as well.

[Afterthought]
When the second one finishes, I'll go back to the earlier version but will leave the .pdb in the Boinc folder to see if it will produce any different output when the next one finishes.

My second one completed as it should, cleaning up all files and not causing any errors for the following task.

So, who's seeing these errors, and what's the common factor?

Version of VBox?
Version of Windows?
Running as a service?

In my case - 4.3.26, 7, no.
