Ticket #10227 (new defect)
Unaligned AIO/DIO with ext4
|Reported by:||melchiaros||Owned by:|
I find from time to time on different linux host the kernel entry:
Feb 8 12:31:52 userhost kernel: [ 1822.712781] warning: `VirtualBox' uses 32-bit capabilities (legacy support in use) Feb 8 12:32:26 userhost kernel: [ 1856.921623] EXT4-fs (sda1): Unaligned AIO/DIO on inode 1179650 by VirtualBox; performance will be poor.
Actual it is on Ubuntu11.10 (kernel3.0.17)with VirtualBox4.1.8. I test it there for backporting repositories, so a statement from you would be fine.
Also actual I am using a debian 64bit(sid) guest that has caused this, but it is not limited to debian guests.
I attach the log of the guest.
- Summary changed from virtualbox conflicting with ext4 to Unaligned AIO/DIO with ext4
