Re: [Starcluster] enlarge volume
This archive was generated by
e2fsck should be run on the partition and not the disk.
sudo e2fsck /dev/sdz1
should work. BTW, if you put a $ in your sample command lines, I think
you are running it as non-root user so I always think you need a sudo.
If you are running them as root, I would expect a #.
Also, I am very confused why the error message says anything about
/dev/sdo, if the disk you ran it on was sdz.
I am having some of the same problems you are, so there is something
strange going on and I don't know what yet. I must have never resized a
starcluster ebs volume. I guess it was something else. I know I have
resized root ebs volumes according to the alestic instructions but never
anything with a partition in it ... I guess. I am working on building
a new version of parted to see if that helps things any.
