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.

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

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."

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

radek_kubka — Thu, 06 Feb 2014 12:38:09 GMT

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 ?

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

lhoffman1 — Fri, 14 Feb 2014 11:14:15 GMT

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 ?
