Hello,
We have two Datacenters with two HP EVA Storage Arrays.
We installed RH Cluster ( two Nodes ) and presented each
Node 50GB from each Storage Array.
Then created PV, VG and mirrored LV on top of this.
( formatted the resulting Block Device with GFS2 )
If i simulate Storage Failure ( unpresent LUN )
the Disk access will stuck for about 1 Minute,
then restarts.
Seems OK, but the failed PV is removed from the VG.
Linear LV, no more mirror available.
Storage 1 | Storage 2
LUN 1 | LUN 2
----------------------
Fabric A and Fabric B
----------------------
NODE 1 | Node 2
LUN1, LUN2| LUN1, LUN2
PV1 , PV2 | PV1 , PV2
VG | VG
LV-MIRROR | LV-MIRROR
How can i readd this PV, and get a consistent mirrored LV ?
I supposed that the LV resyncs after the failed PV is reactivated,
was this a false assumption ?
