1) Message boards : : Number crunching : Planned outage for BOS and ESEA
Posted 3949 days ago by Bruno G. Olsen & ESEA @ greenholt
I've spent the last few days checking everything was working correctly, and it seems so. This is what happened Sunday:

Around 10 am local time, the database drive stalled once again, and I shut down the system, knowing I was going to correct things later.

Around 3 pm local time, I had moved everything to my work area, and wanted to start up to test everything would work fine when attempting to do the drive switch. But now the database drive box didn't start at all - no fan, no light, nothing. The other one seemed to start as usual. I thought it might be the power supply, so I switch to the other power supply - this time the box started, but I really didn't like the sound, so I turned it off quickly. The other box didn't like the power supply from the database drive box.

So, now I had two drives that I didn't know if I could even get working. Anyway, with two drives to switch and only two drives to replace them, I could wave goodbye to my RAID plans. The only hope I had was that it was the external boxes that were failing, not the hard drives themselves. And it turned out to be just that. So after I had copied the database drive successfully, I made the sites available again while copying the other drives - before moving things back where they belong.

I will try to build a RAID with these two new hard drives, but this may take some time, as it is the first RAID I've ever made.


If I knew what a RAID is, then I would say, "Awww that is easy to do." But I have no clue what a RAID is, so I will just stand on my chair and applaud the hard work you do. Ya gots a wrinkly brain there kid ! *smile*

good luck,

Thanks :)

And RAID is a set of different ways to set up hard drives for data security/performance boost except RAID 0, which is a way to set up multiple physical drives as one big logical drive. RAID 1, which was the one I intended to use, creates a mirror of one (or more) drive(s) on another (or more) drive(s). This one increases data security, as one hard drive can fail without loss of data, and increases read speed, as reading can be devided to all mirrors.

There are several other RAID strategies, like stripe sets with parity, which basically splits data onto several hard drives, making both read and write speed faster, and through a drive containing the parity data, makes it possible to restore data if a disk fails.

I wish you all the best and maybe I'm offending you, but I like to mention:

Maybe it is of some help...

No offence taken ;) Not sure I could use it, though, as I'm on the Windows platform. But thanks anyway ;)

For those who haven't read the BOS RSS feed, the BOS message boards or the ESEA message boards, here some info:

The hard drive containing the databases has been giving trouble these last few days. It is close to give up. I have two hard drives which was planned to be used as a replacement for the boot/system drive, but this is more important right now. So this weekend I will spend some time replacing the database drive. I will try to build a RAID with these two new hard drives, but this may take some time, as it is the first RAID I've ever made. Keeping all data/programs completely intact during the process is an extra task, and may make it take a bit longer, as I don't have a third clean hard drive to save things on. But I'll do my best to do this as fast as possible. If all things go wrong I have back-ups.

So, just so you know, the BOS site and services and the ESEA site will be down for a while this weekend.
5) Message boards : : Leiden Classical : new URL

looks like advanced users can edit the master url in the client_state.xml (when boinc is shut down, of course)

As I\'ve seen this on my secondary computer many times with various boinc versions, long before Classical, I\'d say it\'s a boinc problem. I know others have had the same problem as well. It seems it occurs less with each new boinc version (my experience, at least). Sometimes I even have to reboot the machine to get it working properly.

There is a problem with this website\'s security certificate


As mentioned try to leave out the \"s\" in the URL so it only sais \"http\" - some links on the website has had this change, and I guess the rest will follow eventually ;)

BTW, if you can\'t login at our website please email me at bruno at esea.dk

Seems to be a reoccuring problem on all new projects - that and single quotes ;)
9) Message boards : : Number crunching : Stats on BOINCstats
Posted 4277 days ago by Bruno G. Olsen & ESEA @ greenholt
Why not simply turn off new account creation? Then the stats can go public with little fear of being further overloaded by new members.


As I understand it, it is not only a matter of keeping the project from being overloaded. The URL for the project may change - and basically it is not good if an old URL leeding nowhere is spread all over the net. Been there, trying to find AP which had already come and gone when I first entered the BOINC world. Too many people don\'t update links on their websites

It is not a problem for seti synergy...

here

stats are already public !


Yeah, I noticed they\'d done that too. Even when they were asked not too. Bit sad really.


They did the same with Lattice too, I see. Some of us honour the wishes of the projects...
