Ubuntu 18.04 VirtualBox disk full error: "ahci-0-3" (rc=VERR_DISK_FULL)

in flag

On my Ubuntu 18.04 desktop, I installed VirtualBox and added Windows 10 to it. Currently, Windows won't launch because VirtualBox experiences an error stating the following infoprmation:

"An error has occurred during virtual machine execution! The error details are shown below. You may try..."

DETAILS: "The I/O cache encountered an error while updating data in medium "ahci-0-3" (rc=VERR_DISK_FULL). Make sure there is enough free space on...."

"ERROR ID: BLKCACHE_IOERR" "SEVERITY: Non-fatal Error"

Have you tried making more room on the disk?

The **recommended minimum** disk space is 25GB, but that's only a minimum and varies on what you want to do with it. The more software and data you add, the more space you'll require.

I don't think it is full, but could be wrong. In VB settings under "Storage -> Storage Devices -> Windows 10 Virtual.vdi," the following information displays on the right: Virtual size of 121.55 GB Actual size of 53.58 GB Details: Dynamically allocated Location: /media/salmm/Files/VirtualBox_In_Linux/Windows 10 Virtual.vdi Attached to: Windows 10 Vurtual

The error message that you cut short explains the problem: Your *Host* has no more storage space. If you would like confirmation, [edit] your question to show the full output of `df -h`

I found out that the partition the vdi was on had no space left. Thank you all. Can I copy the vdi to another partition and use it on Ubuntu 20.04? I have an SSD on that OS.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
