Description
I just stumbled over this warning in /var/log/messages:
Aug 19 13:22:16 s01en22 kernel: [ 144.131936] EXT4-fs (sdb1): Unaligned AIO/DIO on inode 7345581 by VBoxHeadless; performance will be poor.
any insights on what this could actually mean? i found two things about it on the web ([1] and [2]).
