gilgamesh: update on cluster

[John Kitchin]

It appears there are multiple drive issues on the home server raid array,
including one drive that is totally failed, and one or more with some
errors. odds are high it is lost.

The array is "online" which means it exists, but it is in degraded state,
and I am unable to mount the homes due to xfs errors that cannot be
repaired, possibly from the failed disk.

This afternoon I am going to try replacing the failed drive and see if the
array will rebuild, and if that works, replace the other drives one at a
time with rebuild. this will take a few days to figure out if it works
because it takes a long time to rebuild the ~10TB array. If that works,
then I can try repairing the file system errors, and if it all goes well we
may have minimal data loss. if not, we will likely have total loss of the
homes. hopefully not.
