River Tarnell:
There was an outage this morning (mostly of the web
server) caused by a
fault on the fibre between hemlock and its storage array, which hosts
user-store. I have unmounted user-store until the problem is resolved,
so www is now working again.
Hi,
This has been repaired and the storage is now online, so I have
remounted user-store everywhere.
The problem seems to have been caused by a faulty HBA port on hemlock.
Moving the fibre to the other port resolved the problem, but we will
probably need to replace the card.
Our current purchasing plan includes hardware to provide redundant fibre
connections to each host, to prevent problems like this in the future,
as well as moving user-store to the HA cluster, to protect it from
failure of a single host.
