Hello,
I can not seem to be able to extend slightly a raid volume of mine. I issue
the command:
mdadm --grow --size=max /dev/md5
it completes and nothing happens. The kernel log is empty, however the even
counter on the drive is incremented by +3.
Here is what I have (yes I know that I am resizing only by about 200MB). Why
am I not able to reach 824.8GiB?
Thank you for your help.
