I don't know if this forum is the right one to post my problem, but here goes: I have a virtual disk in a state of formatting for several days, and it still hasn't finished, as shown in the image.
This is not normal, but I also don't understand what could be going on.

Hello Margarida,
 The formatting of a vdisk is a background / low priority task and depending on how busy the Storage is and how large the Volume is that you are formatting will vary the ammount of time it takes significantly.
It is not of any real concern though, as you can use the Volume(vdisk) while it is formatting,  if a write to a block that is not formatted is needed, the FlashSystem will format the block and then write your data to it.
I would not be worried with a large volume format to take days.
