Local storage full wrong

[Nicolas Closs]

My local storage shows that it's full.

I have 2 VMs allocated 455 GB from 852 GB total space in storage, but it shows 855 allocated.

There are no snapshots to be shown in menu snapshots in XenCenter.

As Alan says, just because you've deleted the snapshots it does not mean that the space can be freed. In order to free the space for the snapshot the parent and sibling nodes (to the deleted snapshot) in the tree have to be merged together. This means copying data from the child into the parent and may require the size of the parent to be increased in order to accommodate extra data blocks which are not present in the parent. Once the parent is a complete superset of the data in the child node the child becomes redundant and can be removed, releasing the storage space used by the child.

Do you ever do snapshots? Maybe you were so full at some point that the cleanup stopped working right.

The easiest way to handle it is storage migrate the VM data to another datastore and rebuild this one.

It could be you are on a version/build that has bugs, are you on 8.2 ?

Plus if the SR is something like over 90% full, the coalescing may not work and you may have to move the storage to a different sr to be able to free up enough space to get it to work.

That's it! When I released space, removing one VM, the coalescing worked correctly and in a few minutes, my spaces was right.

Thanks.
