gilgamesh: christmas miracle - of sorts - i think

[John Kitchin]

Hi all,

I believe I have managed to get the cluster to a state where we can recover
data.

Here is the current situation. I replaced two drives, and the array is
rebuilt and reporting to be mostly healthy. However, there are some "bad
stripes" which prevent me from repairing the file system, and the data on
those stripes is almost certainly lost. We are going to have to do some
work that will probably involve destroying the array, and recreating it.

In the meantime, I have mounted the homes as read-only, and it appears I
can access some of the data. Some of the data is unavailable.  That means I
can list directory contents and see contents of some files, but some files
give errors trying to read or copy them. I am working on some options for
backing this data up.

To avoid pandemonium and overloading the server with file transfers, i have
disabled login for now. The best plan I think is to get an external drive
connected to the server to transfer the data (rather than lots of people
trying to rsync).

In the meantime, if there are some super urgent needs please let me know, I
will see what I can do.


John
