Hello. I am working on an Ubuntu 12.04, virtualized by a VMWare server, usually through a remote desktop protocol (see xrdp) or a simple ssh connection. This machine which is rebooted very rarely (basically only when there is an updates which needs a reboot to be applied). This morning, when I've reconnected to rdp session, I found that the root was mounted readonly (visible from the /proc/mount, becouse /etc/mtab was not up to update). After a reboot, and a filesystem check all seems to work, but it was quite a curious situation! Searching on the web I found that it happens tipically when kernel finds bad blocks on the disk, but since it's a virtual disk, I have some question. 1) Can bad block appear on a virtual disk too? Even if it is eventually just a flat file in the host filesystem? 2) Are those bad blocks related to real bad blocks on the physical host file system? Thanks in advance for any answer. -- Mick
