Disk up

the new disk is up and running after less than 4 hours later.

This disk is were Boinc save all past and present data (not the DB, that is in another more faster one) and the downside of a Boinc installation is that space in that area will grown day by day.

As the old one last for more than 3 years, we have at least other 3 years of data to process before fulling this one :)

New disk

in the next days it is planned to move the Boinc data from actual disk to another big one.

The operation will be long 2 or more hours and during that time the server will be disconnected from network.

So be sure to have the WUs you need or add backup Boinc project to use in the mean time

Internet connection restored
So, the electrical power was shout down for 3,5h on Sunday in all the municipal area and the very good news was that the UPS (that was supposed to function for one hour) lasted for all the time and it was not near to finish the power reserve.

UPS is for saving integrity of server when there is no power, not to support all the rest of network equipments.

However when the power was back there were not internet connection!

As the service provider repeater is located 200m of distance and there were no workers on it (so all was supposed to be good), I contacted them soon for the problem as even their networks devices where in the area of power off so the problem could be here and/or there.

As it was Sunday their replay were at the rate of one in an hour and they let me makes lot of test until say at night that they will send a specialized technician to solve it.

I pass all the followed days to solicit intervention because the situation was critical for ODLK1, but it was in vain: assistance with ten-year customers proved to be practically absent!

Really unacceptable for a supplier who should guarantee a service that is always active 24h/24h!

This has now been, today they have restored the connection (it seems that the electrical works have damaged many devices throughout the area of 1Km^2).

I apologize for the situation but even replace the current internet providers will takes at least 20 working days, so the only solution was to attend their intervention.
