The file is currently 20 GB, but it is growing everyday, even though I’m not storing anything new in the guest file system.
I have been looking for hours for a way to reduce the maximum size of this diskso that it never gets to GB I’d like to set the limit to 30 GB, and see what vmware workstation 12 consolidate snapshots free when the VM reaches this size.
Although this task seems technically quite simple there is no tricky shrinking involved, just a simple change of size limitI’m really out of ideas here Defragment the disk via the guest, choosing a defragmentation mode that consolidates empty space at the end of the disk.
For a Windows guest, you приведенная ссылка empty vmware workstation 12 consolidate snapshots free Recycle Bin and turn off hibernation and paging, returning them after the defragmentation is done. Zero all unused space on the disk. For Windows use sdelete : sdelete -c.
Shrink the disk which may take quite a long time to complete. Or use : vmware-vdiskmanager. Converting the disk from growable to preallocated could stop its growing. This can be done using vmware-vdiskmanager with the -t parameter whose values are:. If you wish to change the size of the disk, this should be done while the disk is still in growable format examples here. The file is currently 20GB, but it is growing everyday, even though I’m not storing anything new in the guest file system.
Because the OS and its application programs temporarily use lots of disk space for temporary files, page files, hibernate file and config files. Once they get deleted depending on the policy of the OS new sectors on disk are used at the next time.
The VM allocate storage for the virtual disk from real disk whenever a new sector is used in the virtual disk. As the sector on virtual disk are always not reused by guest OS the VM thinks its a disk usage and give space from real disk and this will lead to growing virtual disk image. Your question title is less likely to be solved as using such a tool without inspection of image may lead to total disaster. But you can prevent growing of the image beyond logic pro x to export song. There are many way to achieve the goal.
Use only 30GB partitioned and leave remaining as free space. As the space in unpartitioned area is never used virtual disk will never grow beyond 30GB. Create a snapshot and restore to it after usage. After creating snapshot VM store data into a new image file. If you restore to it, without saving vmware workstation 12 consolidate snapshots free making new snapshots, all changed data is deleted and thus space is freed.
Create a new virtual disk of maximum 30GB, add it as a new disk into your current virtual machine, move продолжение здесь data to the new virtual disk using a backup tool. You may use a live Linux for the cloning.
The answer of harrym is pretty good, but it actually does not answer the question. The OP wants to reduce the maximum size. The problem is the hypervisor does not know how much of the presented size aka maximum size is indeed used by the OS.
The compaction vmware-vdiskmakager -k applies to a growable vmdk. It does nothing on preallocated one’s. The first step involves a procedure from within the VM and varies with guest OS. The second step could be supported by the vmware commands but I haven’t found a profound way of doing so. Thus the hacky approach. Here is a non so quick due to large data moving involved and dirty solution that did the trick. We will need to have available space equal to the maximum device size.
Find a way to resize the guest partition and leave unallocated space at the end of the device. Two examples:. Make sure you add at least this number to the disk size. Now we need convert the bytes to sectors dividing by and rounding upwards ceiling. Note this number for step 3. As the hack works on single file preallocated type 2 vmdks haven’t tried on multiple file types we first convert the growable to preallocated.
We will temporarily need a partition with physical space as the maximum size of the device. Open the first disk. Find the line. Yes you get vmware workstation 12 consolidate snapshots free point, the second field is the number of sectors allocated for vmware workstation 12 consolidate snapshots free device. This should be the previous device’s size.
Now replace that number with the noted number from step one and save the file. But we resized the fs on the нажмите для деталей of the device and made correct and safe calculations right? Until now no data have been touched yet. Do this final step to actually trim the extends. We will use the rename functionality of vmware-vdiskmanager to recreate the vmdk with it’s size now trimmed.
You’ll have to set the sum of all partitions to be less than 30GB. You’ll vmware workstation 12 consolidate snapshots free to shrink the sizes of the partitions down as you go. Why did you create a GB thin partition if you did not have the space to support it at maximum size?
Seems like this is just asking for trouble. Detailed steps here. Note that any changes to the VMDK size will also need a corresponding update to the partition table. In a Windows virtual machine, you must first run a disk defragment from within Windows.
Defragmenting within Windows ensures that all of the used spaces are contiguous. You can then reduce the size of the virtual disk. Note: In Workstation 9. Therefore, this option is removed from VMware Tools Panel.
This is not available in Linux version of VMware Workstation 9. Click the Shrink tab. Select the drive you want to shrink. Click Prepare to Shrink, then follow the vmware workstation 12 consolidate snapshots free instructions.
Caution: Do not shut down your virtual machine or the host machine while the disk is shrinking. Also, do not try to cancel the process. Interrupting this process can cause irreparable damage to your virtual disk and you may not be able to start your virtual machine again.

Improve this answer. DanielB: No, it doesn’t reduce the maximal size, just the physical size. Reducing the maximal size can be dangerous, as some OS cannot boot without some free space on the system disk.
However, this does not completely solve my problem, vmware workstation 12 consolidate snapshots free if I want to keep the VMDK always vmware workstation 12 consolidate snapshots free, let’s say 30GB, I will have to periodically repeat the operation which takes a long time indeed. If the disk can always be slimmed down to the wanted size, meaning that the procedure above always works to reduce the size, then you could limit the size in the future by converting the disk to fixed-size.
Vmware workstation 12 consolidate snapshots free.VMware Snapshot Consolidation | What, When & How
Do you know that you still need to perform VMware snapshot consolidation after the failure of reverting or deleting a snapshot? This article will introduce it to you in details. In vSphere 5, VMware introduced the Consolidation option, which is used when the associated disks are not committed back to the base disk after you revert or delete VMware snapshots.
You will remove redundant delta disk files that are left over from failed snapshot restore, delete, or delete all operations. It can improve the VM performance and save storage space. Snapshot consolidation does not require additional free disk space if all VM disks are thick provisioned. But if your VM disks are thin provisioned , it may require up to the same size of free space as the snapshot size.
In general, the larger the snapshot is, the longer the snapshot consolidation process will take. But it is not easy to determine exactly how long it will take. Many other factors may affect it directly or indirectly, including the depth of the virtual disk snapshot chain, the type of data, the storage array performance, etc. You can estimate the time required for snapshot consolidation by monitoring the throughput on the datastore, monitoring throughput for snapshot consolidation only, or estimating the time on a test VM.
If a VM requires snapshot consolidation, you will get a VMware error: virtual machine disks consolidation is needed to inform you that there are redundant delta disk files. To solve the VMware error: virtual machine disk consolidation is needed, you just need to perform the snapshot consolidation as required. In addition, it can further save storage space and improve VM performance. Open an SSH shell session to the host that is performing the consolidation and snapshot deletion task by running the following vim-cmd command:.
If you encounter the VMware error: An error occurred while consolidating disks. Here are the possible reasons and their solutions:. As you can see, taking too many snapshots, or keeping them for long can both lead to many errors, even data loss. This is because the snapshots are dependent on the parent disks.
Therefore, snapshots are often used as quick failsafe before performing development or testing, capable of rolling back in case of any problem. But if you want a VM data protection measure in production environments, it is much better to take a VM backup than a snapshot. A VM backup is an independent copy of the VM that can be safely stored offsite, cloud, or other locations.
By restoring from a VM backup you will get an instantly usable VM. If you encountered the VMware error: virtual machine disks consolidation is needed, it is informing you that you need to perform snapshot consolidation manually after the snapshot revert, delete, or delete all operations.
In this article, I introduced what is VMware snapshot consolidation, when and how you can perform it on your VMs, analyzed the reasons why the snapshots consolidation fails and the relevant solutions. Snapshot consolidation often fails because of the improperly usage of VM snapshots.
Most importantly, please do not take VM snapshot as VM backups. What is snapshot consolidation Snapshot consolidation is used to merge the snapshot delta disk files to the VM base disk. Consolidating a snapshot : You will remove redundant delta disk files that are left over from failed snapshot restore, delete, or delete all operations.
How long does snapshot consolidation take In general, the larger the snapshot is, the longer the snapshot consolidation process will take. There is no free space on the datastore to perform consolidation. Third-party backup application is performing backups thus locked snapshot files. You have too many snapshots up to 32 recommended by VMware.
You have one large snapshot is consolidating now. How to perform snapshot consolidation To solve the VMware error: virtual machine disk consolidation is needed, you just need to perform the snapshot consolidation as required. In this section, I will introduce 3 different ways to consolidate snapshot. How to perform snapshot consolidation via ESXi web client 1.
The reasons why snapshot consolidation failed and solutions If you encounter the VMware error: An error occurred while consolidating disks. The content ID of the parent virtual disk does not match the corresponding parent content ID in the child — correct the CID of the disks reference each other using text editor. The free space is not enough — free space on the datastore msg.
