Hi all
Please help to understand why space reserved LUN in space reserved volume went offline. ONTAP cDOT 8.3RC1
Volume Hyper_V_boot 200Gb, guarantee volume. (it was increased by autogrow later, you'll see output with increased values)
No snapshots.
Two LUNs created in that volume 80Gb each. 80Gb+80Gb=160Gb used, in theory. Now I see 55Gb reserved in a volume.
Host - Windows 2012 Hyper-V two node cluster.
One of LUNs went offline while copying VM from other storage to this LUN.
I can't understand why it went offline. This is unaccepatbale with resrvations ON.
Maybe it was related to ODX and it tried to create a sis clone??? Please help.
Thank you
Nick
