Hi!
First off, thank you thank you thank for making such a great product in
Starcluster. I'm fairly new to Amazon cloud computing, and Starcluster has
make it so easy to spin up a cluster of machines for my research.
I was resizing a 100GB attached volume to 500GB using the "resizevolume"
command, and it got pretty far along but then crashed. I've attached the
bug report and also pasted the terminal output below.
In the end, I finished the resize manually using resize2fs, umounted my old
(100 GB) volume and mounted the new one. So things seem ok.
Looking forward to release of version 0.94 so I can use one of the Ubuntu
12.04 AMIs, which have should have current glibc libraries that will play
nicer with my own Ubuntu 12.04 machine!
Thanks again!
