If I can receive any assistance in troubleshooting the issue I have. thanks

scsitarget.lun.noSpace:error]: LUN '/vol/Files_backups/Files_backups' has run out of space.

Re: Volume 990GB - LUN 900GB - but im out of space

Hi,

It may be the case that fractional reserve kicked in.

What is the output of:

df -r /vol/Files_backups

?

Re: Volume 990GB - LUN 900GB - but im out of space

Same problem here after aggregate was full. I reduced the snap reserve on that and delete all snapshot. (aggrX  13TB       13TB      650GB      95%)

NetApp Release 7.3.2P3: Fri Dec 11 18:10:24 PST 2009

Volume has 1550GB, LUN is thin with 1.5TB and use only 957GB...

Any idea ?

Re: Volume 990GB - LUN 900GB - but im out of space

So my first guess will be as above - fractional reserve?

What's the output of

df -r /vol/your_vol_name

?

Re: Volume 990GB - LUN 900GB - but im out of space

Hi,

you have to increase your volume immediately or just delete the contained snaps..  You have taken snapshots which consumed  20406916 , this value you have to add with the consumed LUN space of  915798232 !  

That's why the LUN itself has no sufficient space anymore.

change/adjust your snapshot scheduler for the future.

Not quite. Snap reserve is set to 0% for this volume, so any space taken by snapshots is included in the first line of the output.

I think the following message is not true, but I don't know how I can remove it...

"Thu Feb  6 07:13:03 CET [scsitarget.lun.noSpace:error]: LUN '/vol/vol1' has run out of space."

Re: Volume 990GB - LUN 900GB - but im out of space

Thats correct for the user above, but what do you think about my similar problem ?

Re: Volume 990GB - LUN 900GB - but im out of space

Where is this message coming from?

There is space within volume & there should be space within LUN as well if we use simple arithmetic.

Re: Volume 990GB - LUN 900GB - but im out of space

The message is from the logs (messages) and is displayed continuous on the console.

Th Volume (thick) has 1550GB, LUN is created with 1.5TB and use only 957GB on the volume.
