Disk reported full

[brombloke]

Hello, Everytime I try to use virtual box it pauses with the message "disk full" this is incorrect as their is 2 1/2 gb free! The guest o/s cant be restarted unless i shutdown and then restart which just repeats the problem. I'm using gentoo. i have virtualbox on a 6gb partition. the xp installation takes up 3 1/2 gb so there is plenty os space. thanks

i discovered that apportioning the entire space on a partition to virtual box is the wrong thing to do. on re-installing vbox i allocated 5gb on a 6gb partition to virtualbox which fixed the disk full problem and all works very well. didn't see that in the documentation anywhere but i've learned that allocating all the space to virtualbox will always eventually result in the disk full error and an unusable guest. thanks

Could you attach your VBox log here? (~/.VirtualBox/Machines/vm_name/Log/VBox.log) Of course a log of such a failed session.

Are you sure you didn't put the disk image on a filesystem which doesn't support large files? The only similar reports I've seen have been from people putting the VDI on a FAT32 partition. Which is limited to 4GB by design. Not very much for a disk image.

yes i'm almost positive. it was reiserfs partition. it was the host (gentoo) that reported disk full. i think the host gentoo needed to write some stuff to this partition but couldn't because the space was unavailable (guessing). since i only allocated 90% of the space on the larger than original partition to the vbox i have had no problems. in short.. i would recommend that say on a 5 gig partition only allocate 4.9 gig to allow the host some space to do it's thing. glenn

We've clarified the meaning of dynamically expanding hard disk containers in the GUI. (last comment)

This simply looks like a user configuration issue. Maybe the ReiserFS partition used a too small sector size, thereby restricting the maximum file size.
