"Delays, Delays"
Hopefully it will not require another database rebuild.

Thanks for the Update.

Message 1617160 - Posted: 22 Dec 2014, 2:17:03 UTC - in response to Message 1617071.  

Marvin isn't finding a boot device on reboot. I'm not even sure it's seeing the RAID card at all (these remote interfaces to the boot screen aren't good at capturing things that happen quickly). Matt and I are meeting at the co-lo first thing tomorrow morning. I'm bringing a boot CD and what I think is a matching RAID card.

Any news on Lando? The SSP still shows Lando splitting APs and only 3 MB splitters working.

I take it it's not OK to leave it as it is until Monday in it's crashed state then? If non of the remote stuff works?

It's mainly generation of astropulse work that will suffer. No permanent damage should result. But I'd like to have everything in working order before folks do leave for the holidays.

Could you ask them to take a look at Lando as well tomorrow, please? Lando's four MB splitters don't seem to have been pulling their weight since Marvin went down.

The splitters on lando are hung waiting for the database to come back, so they are running, but not doing anything.

I'd expect that for the AP splitters, but I'm surprised that needs to affect the MB splitters as well? But thanks for looking.

Chicken and egg question.

When AP database is "working", is the database problem cause of poor AP slitting, or are the AP splitters cause of database problem?

P.S. If problem is not fixed by tomorrow, please leave it and go home or you will be facing cold shoulder and hot tongue over the festive season.

Hard end of year, indeed...
In next year more decoupled MultiBeam and AstroPulse workflows would be appreciated.

And Eric The Man has done his job, now 6 splitters doing work on MB.

I wish a good luck for marvin getting up.

Marvin is back up. For some reason the 3-ware BIOS was not being detected on reboot. After several attempts to make it visible we flashed a new BIOS. On the next reboot it came right back up.

The database is in transaction cleanup mode (which can take a while). Once that's done I'll survey for damage and if everything looks OK I'll restart the daemons.

Hmm, and what about the "root partition filled on marvin (rapidly)" that you initially wrote when Marvin crashed. Is that still the reason it crashed, and why would that happen?

"Filled up" might have been remote access shorthand for "has no visible free space" - which would be the case if the controller couldn't see the disk. Or something like that.

That's a good question. Apart from some email warnings we don't have any stored records of what happened at the time of the crash. It's likely that all the disk volumes disappeared simultaneously, but that doesn't really explain why we got any warning.

That might depend on how syslog is written. The warning message might have been passed in RAM and it was able to e-mail it but unable to find a disk to write it too, which would have generated another warning message.

I see the transitioner is down now, data being received but nothing is going out from seti. All graphs are frozen in time for 9 hours.

It's easy

If it doesn't move and it should you need a hammer

If it does move and it shouldn't use duct tape

If non of the above then it's an electrical problem and you need an electrician
