Re: WAFL Inconsistent

EMMANUEL_LANDIVIER · ‎2014-09-16

Hello Communities,

I have a FAS on 8.2 7M on witch I have lot of flexible volumes.

I configured Flexcone to test this functionality and did a clone on one small volume (~200MB)

Last week-end electrical power outage occurred and unfortunately this volume and his clone became "WAFL Inconsistent".

I don't care of data inside.

I did a wafliron on aggregate yesterday, no WAFLcheck on this release of Netapp, but nothing to do volumes still WAFL Inconsistent.

Already tried to offline parents volume and destroy it but it has a clone...

Already tried to offline clone volume and destroy it but I have to split first. Split failed because parent volume is not online...

The snake biting its tail

Does anyone can help me?

Maintenance mode, systemshell command exist?

Thanks a lot for all answers.

Emmanuel

I assume that since you had a power outage, you losts disks and your aggregate became wafl inconsistent, not just the volume. right?

Can you show us output from aggr status

Hi JGPSHNTAP.

No disk failed and aggregate is OK.. Only volume and clone mentioned above.
