suppress takeover for certain aggregate

[HolgerDD]

following situation

1) MC with 8.2.3 7-Mode
2) each site
aggr0 mirrored
aggr1 not mirrored

It's possible to suppress a takeover only for aggr1 during failover?

[aborzenkov]

No. Filer will configure all aggregates it sees.

Hi,

What is the reason for your question ? Maintenance ?

Do you mean a normal Failover or a Site-Failover ? In a normal takeover the aggregate is still available, but in a Site-Failover the aggregate can't be used.

-> Site-Failover of an asymmetrical mirroring

But if this occurs (e.g. controller A fails) and controller B have no access to a certain aggregat of controller A at this time, a kernel panic is possible. right ?

[aborzenkov]

It should not panic. Some aggregates will be missing after takeover, that's all. Of course if root aggregate itself is missing, no takeover is possible.

[MarcSchindler]

That's correct.

It should not panic, especially if the release version is equal or above 7.1.x.

Did you have the problem after a takeover ?
