Hi,
I rebooted my server today to find out that one of the arrays is being
re-synced (see output below)
.
1. What does the (S) to the right of hdh1[5](S) mean?
2. How do I know, from this output, which disk is the one holding the
most current data and from which all the other drives are syncing
from? Or are they all containing the data and this sync process is
something else? Maybe I'm just not understanding what is being done
exactly?
Thanks in advance for the help.
Shai
