I need to move a VM to another, so I checked the VM folder and discovered that one (out of 3) disks was running off a snapshot.

# grep vmdk SQL01.vmx

scsi0:0.fileName = "SQL01.vmdk"
scsi0:1.fileName = "SQL01_1-000001.vmdk"
scsi0:2.fileName = "SQL01_2.vmdk"

Additionally I discovered that the Acronis appliance had extra disk(s) attached:

# grep vmdk acronis01.vmx

scsi0:0.fileName = "HardDisk_1.vmdk"
scsi1:0.fileName = "HardDisk_2.vmdk"
scsi1:4.fileName = "_dsqnap__SQL01_SQL01_1.vmdk"
scsi1:4.redo = "./_dsqnap__SQL01_SQL01_1.vmdk.REDO_Z6ytPv"

Further findings (according to: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&c… )

# find /vmfs/volumes/ -iname "*.vmx" -exec grep -HEie "-[0-9]{6}.vmdk" {} \;

/vmfs/volumes/9881eafb-da40f427/SQL01/SQL01.vmx:scsi0:1.fileName = "SQL01_1-000001.vmdk"

# ls -lah /vmfs/devices/deltadisks/

-rw-------    1 root     root      500.0G Jul 13 13:36 184742c3-_dsqnap__SQL01_SQL01_1.vmdk-delta.REDO_Z6ytPv
-rw-------    1 root     root      500.0G Jul 13 13:36 6da24184-SQL01_1-000001-delta.vmdk

# find /vmfs/volumes/ -iname "*delta.vmdk"

/vmfs/volumes/9881eafb-da40f427/SQL01/SQL01_1-000001-delta.vmdk
/vmfs/volumes/588ddc51-b076e1bc-8c9e-1402ec6b7d88/acronis01/_dsqnap__SQL01_SQL01_1-delta.vmdk

How do I go about cleaning this up?

1. Can I remove the extra disk (Delete from disk) from Acronis appliance?
2. Can I cleanup the snapshot by first creating a new snapshot and then remove all snapshots?

Any help is appriciated.

TIA,
Kristian

Hi Kristian,

The proper cleanup method is to remove the attached disk from appliance configuration (delete from disk):  "_dsqnap__SQL01_SQL01_1.vmdk" - this disk locks the snapshot on the original VM, so it must be removed from appliance first. After that you can create a snapshot of the original backed up VM and remove it - it will effectively consolidate the snapshot file after that.

See also the following KB article describing the process.

Thank you.

Thank you, Vasily,

That was also what I had planned, but now I am more confident in performing th procedure. :)

For extra security, I am now testing a restore of the lastest backup on another host.

Regards,
Kristian
