Re: csum errors in VirtualBox VDI files

This is kinda confusing. So the gist is that the guest OS is Windows, so the VDI contains an NTFS file system. Correct? And that VDI is on a Btrfs formatted bcache device. Correct? Does the VDI have +C xattr set? Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe

csum errors in VirtualBox VDI files

Hello! Since one of the last kernel updates (I don't know which exactly), I'm experiencing csum errors within VDI files when running VirtualBox. A side effect of this is, as soon as dmesg shows these errors, commands like "du" and "df" hang until reboot. I've now restored the file from backup
