Free space on datastore.

VMware specific discussions

Re: Error: Insufficient free disk space on production datast

The message comes from Veeam.
VM's with this error all have a physical RDM, but I thought that phisical RDM will automatically be skipped by Veeam.
Also tried to replicate the server but also get this error.
There must be a way to backups only the VM systemdisk without the pRDM, right?

Yes, by excluding specific disks in the job properties...

Yes, it is skipped, but the snapshot is still taken for the entire VM.

this is the only way i believe you can work around this, i'm open to be corrected, because we currently have some extremely large vm's we're needing to just do a backup of the 0:0/system drive, but we don't have a datastore that's large enough for the snapshots.

I believe the above will allow a change in the snapshot location.

Yes, changing the workingDir parameter should help.

[MERGED] Question on VeeamZIP backup and free space

Veeam Logoby coryvmbkp » Wed Aug 21, 2013 3:03 pm

Hi,
I just started trying out the free version of veeam, for vmware. I've run the veeamzip on a couple vm's and so far it seems to work.
On this other vm though, I'm running into the error: "Production datastore 'backup' is getting low on free space (305.0 MB left), and may run out of free disk space completely due to open snapshots. Error: Insufficient free disk space on production datastore 'backup'."

Basically, on my vmware host there are 3 internal hard drives. All my other vm's use 2 of them, but the vm I'm trying to back up is as follows:
VM -> primary hard disk on one of the two disks that other vm's (with successful backups) are on.
VM -> extra disk - for extra mount point in linux, and an extra disk - for nfs shares and samba shares ---> these are both stored on a datastore of their own that is fully used (thick provisioned disks) so it has the above 305MB free).

But, the Settings for the two extra disks, in vmware, have the checkbox "Independent" checked. This says "Independent disks are not affected by snapshots". So I'm not sure why the veeam backup is failing without free space, as these two extra disks shouldn't be affected by snapshots, and the vm and it's primary hard disk is on a datastore with plenty of free space (>800GB).

Thanks

Hi Cory,

Try to use the workaround with workingDir parameter, meanwhile I will try to find out if there is any registry key to change the threshold that prevents you from backing up this VM.

Thanks!

[MERGED] Error: Insufficient free disk space on....

Veeam Logoby dannyvdz » Mon Sep 09, 2013 1:47 pm

I am trying to backup a Ubuntu Server which is running on ESXI 5.1
The server has 5 drives assigned as separate virtual drives. I excluded all but the OS-drive which is 50 GB (otherwise I'd backup 2,75 TB).
However when I start the backup I have insufficient space on my datastore. I checked my datastore and I have a total of 250 GB free space.
How can I fix this? I tried removing and adding the job again and checked my my settings several times..

Hello Danny,

Even if you exclude disk from the backup job, the snapshot is still taken against all VM disks. The only way to exclude disks from snapshotting is to make them independent.

Thank you!

Ok, thanks for the info but how is this done best?

Nevermind.. I think I found out how.. now just let me see if backups work!

Unfortunately this doesn't change Veeam's behaviour, There still insufficient free disk space :(

You can try to use the reg key below (should be applied to the main Veeam B&R registry hive) which will change the threshold for this error message, but doing this is highly NOT recommended, because this may cause you issues in future.

BlockSnapshotThreshold - the default value is 2 (GB), try to set it to 0

[MERGED] Veeam error insufficient space

Veeam Logoby klre » Sun Feb 09, 2014 4:17 pm

Hi,
I've got the below mentioned error message when I try to do a full backup of a server with 2 disks.
System Disk: Disk:0:0 (on datastore 1)
Data Disk: Disk:0:1 (on datastore 2)

Error message:
Processing 'Server' Error: Insufficient free disk space on production datastore 'datastore 2'.

I know this message appears if there is not enough space for the snapshot.
But my problem is, I don't want to take a snapshot of disk:0:1. I also set this disk as independent, to make sure, vsphere won't take a snapshot of it. With the snapshot-manager everything works fine, but with veeam it doesn't.
Is there a known issue with this or any workaround?

thank you in advance.

Reto, as a workaround you can either try to reg key above, or use a VMware WorkingDir VM parameter to resolve this issue. Thanks!
