Question

I/O errors

My Ubuntu 12.10 instance failed with the following errors. According to DO support, it is an issue with my VM, not the host. Did anyone else experience this? I think it is a bit dodgy, as it was quite a vanilla install running almost idle (apart from a single “wget” cronjob once an hour).

At the moment I am running fio tests to see whether I can recreate the issue (according to this thread; https://bugzilla.redhat.com/show_bug.cgi?id=549981 )
