Free space on datastore.

Hi Erik,
The VMDK is stored on a 8MB block datastore. The datastore I configured to store the snapshots to is 4MB. Should I change this to 8MB just to keep them the same?

I'm not sure actually... It should not matter for the hotadd functionality, but maybe vSphere is bothered by the fact that the snapshot file COULD potentially grow as big as the original VMDK?? Still, in that case you would be unable to create a snapshot manually as well... Have you tried this?

Erik is spot on. Durand, please search the forum for your error, there are a few dozens of posts regarding this issue.

Creating a manual snapshot results in the same <unspecified datastore> message. I will be updating the workingDir later tonight and will let you know if moving that to a 8MB block datastore will fix this.

Seems to have worked. Very strange that this would all of a sudden come up. This backup had been going for a long time without issues...

Good thing it is solved though :) Maybe Veeam support can find the underlying reason, but it appears to be a VMware issue and not a Veeam issue.

[MERGED] Backup error

Veeam Logoby Dale.E » Mon Jul 16, 2012 5:13 pm

I am new to Vmware and to Veeam Backup, so please bear with me and my learning curve :)

Before virtualization I used Ghost to create disaster recovery images.
I am now planning our new disaster recovery scheme and testing Veeam Backup to create the needed VM images.

It looks good and I have backed up all the small servers no problem, but when I tried our main server I got a space error?!?

"Production datastore 'DataVolume1 Raid 10' is getting low on free space (292.0 MB left), and may run out of free disk space completely due to open snapshots.
Error: Insufficient free disk space on production datastore 'DataVolume1 Raid 10'."


I understand the problem but I am not sure how to work around it.
The root of the issue is with how I laid out the server:
2x300GB Raid 1 Mirror - O/S and boot volume.
8x146GB Raid 10 - Data volume. This is only used by the main server O/S - W2k3 and shared to all domain clients from there.

When I did the p2v I stayed with the basic design and put all the VM O/S's on the raid 1 volume called 'O.S.Volume.Raid1'
and I created a FMFS on the raid 10 array called 'DataVolume1 Raid 10'
The main server O/S was given the data volume and I created a full NTFS volume to be shared from there. So its full, the NTFS is not but according to VMware 'DataVolume1 Raid 10' is full. Now the whole VM is listed as 647.2GB and there is nowhere to create the snapshot.

I like to keep my data separate, and TBU the whole thing once a week with daily changed file backups.
I like to take monthly image snapshots of my O/S for disaster planning.
I appear to be stuck....

Any pointers?

Error: Insufficient free disk space on production datastore

Veeam Logoby jjblaster » Fri Nov 16, 2012 5:28 pm

All,

I am having a problem backing up a single VM. We are running ESXi 5 and Veeam 6.1.0.205.

This is a remote site with 9 VMs. The backup outgrew the 2 TB storage allocated for the backups repository so I added another 2 TB datastore and mounted it on our Veeam backup VM. We backup the Veeam backup VM OS disks but exclude the 2 - 2 TB disks in the virtual machine options in the Veeam backup job.

Ever since added the new 2 TB datastore I get the following error when trying to backup the VM even though I have the disk excluded in the Veeam Job.

Production datastore 'BackupVM02-BACKUP02' is getting low on free space (2.0 GB left), and may run out of free disk space completely due to open snapshots.
Code: Select all
Error: Insufficient free disk space on production datastore 'BackupVM02-BACKUP02'

If I remove the new 2 TB disk from the VM setting the the job runs fine and I have the original 2 TB mounted and excluded.

Any ideas on why I am not able to exclude the new 2 TB disk I added to the Backup VM?

Thanks

Even if you exclude the disk within Veeam they are still included by VMWare in the snapshot creation process. I assume thats the reason why you get that error as you have insufficient space left on the datastore for the snapshot. Now you have two options. Or you reduce the size of the second disk so enough space is left on the datastore for snapshot creation or you edit your VM and configure your second disk as an independent disk. Independent disks are excluded from VMWare snapshot creation process. And they are automatically excluded by Veeam too as backups rely on snapshots.

Or exclude the disk from being processed for Backup under the Backup Job Configuration -> Exclusions -> Disks..

This wouldn't exclude the disk from snapshot process by VMWare itself as far as it isn't setup as an independent disk.

[MERGED] Production datastore 'RDM_Mappings' is getting low

Veeam Logoby hoogvliet » Mon Feb 11, 2013 1:30 pm

Hello,

I have a problem with some VM's in my Veeam Backup Jobs.
Some VM's have a Physical RDM, I only need to backup the VM so at disk exclusion I only choose for the system disk, but when I run the backup i still get the following error:

Production datastore 'RDM_Mappings' is getting low on free space (1.5 GB left), and may run out of free disk space completely due to open snapshots.
Error: Insufficient free disk space on production datastore 'RDM_Mappings'.


I only choose to backup the system disk and still get low free space on 'RDM Mapping' Datastore.
Does anyone know what i can do to fix this?

Thank you!

I'm afraid the only solution is to increase free space on your source datastore.

Uhm, this is however a strange error message. Do you created a dedicated datastore for RDM mapping files? Are there any other files into that datastore? Bacause minimum size of a snapshot is 16 Mb at time of creation, and it then grows as new data are written into it. Since is a physical RDM no snapshot activity should occur on that datastore...
Is the message coming from Veeam or vSphere?
