Hi,

It may be the case that fractional reserve kicked in.

What is the output of:

df -r /vol/Files_backups

?

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 ?

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

What's the output of

df -r /vol/your_vol_name

?

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."

Where is this message coming from?

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

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.

mhh.. it is true you have  nosnap on,  but nevertheless,  what says  "snap list" ?   was says   sis status /vol/vol1   ?    and of course the question how much space is available within the aggregate yet ??     what about the SIS Metadata?   so , what is the output of  aggr show_space -g  of the content aggregate ?

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.

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

your problem is the not sufficient space within the aggregate !  that's why your volume is  100% full  ...  and with that the LUN too !

I have enough and more space in the aggr. And, I use a thick volume...

-> Snaps all deleted and we have enough (more as 600GB) on the aggr

-> What do you mean with "what about the SIS Metadata?" ? Dedup ist enabled on the volume. Do you think the dedup db on this volume is corrupt ?
