Min Chen commented on CLOUDSTACK-6797:
--------------------------------------
Assigned to Marcus to investigate this issue since he is the expert on resize
volume feature. Based on communication with Prashant, the problem is this:
although resizeVolume did resource limit check and maxVolumeSize check in the
flow, it didn't really check the real available storage space in a storage
pool. For attached volume, it replies on sending resizeVolumeCommand to storage
pool to error out, but for detached volume, it will succeed even though user
gave a very large size that outnumber our storage pool capacity. Actually
relying on sending resizeVolumeCommand to storage pool to error out is not an
ideal solution, the better fix should be checking currently available space on
storage pool to early abort if a big size is provided, just like how we did in
StoragePoolAllocator to check whether a pool has enough space.
> volume resize should not be allowed for detached volumes

> =>since resize space is counted in allocated space even though it cant be
> attach to VM , other storage operation will fail because threshold value
> If resize is allowed in volume detach
> ==============================
> 1-since there is no check for how much can be increased , suppose user has
> resized it to 1000GB
> 2-when user try to attach volume to vm it will fail since available space is
> not sufficient .
> 3-even though user is not able to use the resized volume ,CS will count
> 1000GB in allocated storage .
> 4-Dash will show allocated percentage >100%
> 5-Because threshold values , we cant perform any operation to that PS
> If resize is allowed online ( volume Attach) state it will fail in first
> place and will not cause any problem
