Hello,
today adenia finally died - OS not found.
Fortunatelly all relevant data was already on the SAN so I could move the DBs completely to cassia. The host alias sql also points there.
user-store had to move as well and is now active on cassia, too.
It was an interruption of about 2,5h all together.
This regards very few users only but you should know since OSM and Merls tools were not accessible and are probably still broken if they dont use the hostname "sql" for the queries.
Cheers
nosy
