Hi,

  I have defined thin LUNs on the array and presented them to the oVirt hosts. I will change the LUN from thin to preallocated on the array (which is transparent to the oVirt host).

Besides removing “discard after delete” from the storage domain flags, is there anything else I need to take care of on the oVirt side?

All the best,

Oliver

Hi,

What do you mean by converting the LUN from thin to preallocated? 

oVirt creates LVs on top of the LUNs you provide

Hi all,

  I have to move some FC storage domains from thin to preallocated. I would set the storage domain to maintenance, convert the LUN from thin to preallocated on the array, remove “Discard After Delete” from the advanced settings of the storage domain and active it again. Is there anything else I need to take care of?

All the best,

Oliver
