"Sparsebundle ... is already in use."

I am using a MacMini with OSX 10.9.1, 2.3 GHz i7, and 4GB RAM.

Apologies if this question has been asked frequently. I attempted to ask this question in the apple support communities here but got pretty much trolled by a particularlly unhelpful individual.

I have been using Time machine successfully with Mountain Lion (and all othe OSX's 10.8.x and below) and the ReadyNAS Duo v2, RAIDiator 5.3.8, without incident. However upgrading to Mavericks I now find that Time Machine delivers the error "The Backup disk image ... sparsebundle ... is already in use." or it hangs at 'Backing Up'.

What I have tried without success:
1. Following information listed on Pondini which appears only to be valid for either Mountain Lion or Time Capsule.
2. Restarting both the ReadyNAS and Mac Mini in combination as suggested here.

Has anyone experienced a similar problem, or is this something which the Folks at Netgear are aware of? I'm happy to roll back to Mountain Lion as Mavericks doesn't do anything for me (and had an abundance of software I regularly use made redundant in one terrifyingly foul swoop).

Any suggestions how to get things working again would be welcome too :D. I'd thought about ps aux ing the NAS and seeing if there was a way to kill the process but tbh my knowledge is insufficient and I don't really know what I'm looking for :oops:

  • Hi,

    I have seen same issue. It started I think in 6.1.4 or 6.1.5. It is still present in 6.1.6 RC13.
    To resolve this issue, is needed to go Backup -> Time Machine and turn feature off and back on.
    After that backups work fine for a while.
  • I've had this happen on occasion on multiple TM platforms if a backup is not gracefully interrupted. All that was required was to reboot the target device (in this case the ReadyNAS).

    That said, after OSX 10.6.8 I cannot actually keep a TM backup on the ReadyNAS. OSX's periodic verification requires I start the backup over from scratch every month or so. This occurs with 10.7.5 and Mavericks.

    I gave up on the RN104 and my TM backups now go to a drive on my Ubuntu server. No issues there. So something is wrong with the ReadyNAS TM implementation.

    I'm running 6.1.1

    If this has this been specifically addressed in a later firmware I might consider going through the pain of updating, but I otherwise have a stable system.
  • I'm having similar headaches to the posters above as well - getting both the "Sparsebundle in use" and "Verification errors", and am at the point where I am considering selling the ReadyNAS and buying an alternate product as this was a major purchasing factor.

    Have updated to 6.1.6 and using mavericks.
  • Well I guess seeing this... I'm not alone with this issue and not alone in thinking of getting rid of my readynas
  • I'm now seeing this for my users as well. Since I'm using this box as an iSCSI share rebooting it isn't trivial. I have several production VMs that must be shutdown before I can reboot. :(
  • I started seeing this as well. As a long time ReadyNAS user I've been real disappointed in the Time Machine support. I'm always nervous it's just going to stop working again.

    Anyway, I started seeing this sparse bundle is in use error on one of my Mac's and all the usual things were not working. I also use this particular ReadyNAS as an iSCSI target for some VMWare VMs, so rebooting it means shutting them all down. But before I did, I thought, what might reset the connections? It uses AFP I'm pretty sure. So I just went into Frontview, went to standard file protocols, unchecked both the Advertise AFP Service over Bonjour and AFP boxes, Applied, then immediately re-checked them and hit apply. Then I went into Time Machine and re-selected my backup disk. To my surprise, this worked! The backup ran successfully. So I did not have to reboot my ReadyNAS. I'll be curious to know if it fixes it for anyone else.

    I sure hope they are able to correct these inconsistencies in the Time Machine support in a future update. Otherwise, I'm going to have to pick up a Time Capsule to backup our Macs.

    Thanks!! That works here too!

    Amen to that :(
  • Likewise - I just reformatted my ReadyNAS NV+ v2 and created new backups - my Air after just 2 days it's complaining about the sparsebundle already in use - and it's my experience says it's just a matter of time before I'll have to start over on each of my backups.

    Another vote for Netgear to *finally* get Timemachine backups working correctly. (This is so much better than on the v1 NV+)
