aggr split aggrname/plexname new_aggrname
Removes plexname from a mirrored aggregate and creates a new unmirrored aggregate named
new_aggrname that contains the plex. The original mirrored aggregate becomes unmirrored. The
plex to besplit from the original aggregate must be functional (not partial), but it could be inactive,
resyncing, or out-ofdate.
Aggr split can therefore be used to gain access to a plex that is not up to date with respect to its
partner
plex, if its partner plex is currently failed.
If the aggregate in which plexname resides is embedded in a traditional volume, aggr split
behaves identicallyto vol split. The new aggregate is embedded in a new traditional volume of the
same name.
The aggregate in which plexname resides must contain exactly one flexible volume, aggr split will
by defaultrename the flexible volume image in the split-off plex to be the same as the new
aggregate.
If the original aggregate is restricted at the time of the split, the resulting aggregate will also be
restricted. If therestricted aggregate is hosting flexible volumes, they are not renamed at the time
of the split. Flexible volumeswill be renamed later, when the name conflict is detected while
bringing an aggregate online. Flexible volumesin the aggregate that is brought online first keep
their names. That aggregate can be either the originalaggregate, or the aggregate resulting from
the split. When the other aggregate is brought online later, flexiblevolumes in that aggregate will
be renamed.
If the plex of an aggregate embedded within a traditional volume is offline at the time of the split,
the resultingaggregate will be offline. When splitting a plex from an aggregate that hosts flexible
volumes, if that plex isoffline, but the aggregate is online, the resulting aggregate will come online,
and its flexible volumes will berenamed. It is not allowed to split a plex from an offline aggregate.
A split mirror can be joined back together via the -v option to aggr mirror.
