Yend seismometer isolation kit (elog 8461) hosts Guralp seismometer. I made a cable for inside connection, assembled the kit and relocated the instrument from its previous position at the yend inside the kit.
Seismometer is connected to the readout box and running.
I went to Ottavia, and tried running yum update. It was having dependancy issues with mjpegtools, which was a rpmforge provided package. In order to get it to update, I moved the rpmforge priority above (a lower number) that of epel ( epel -> 20 from 10, rpmforge -> 10 to 20). This resolved the problem and the updates proceeded (all 434 of them). yum update on Ottavia now reports nothing needs to be done.
I went to Rosalba and found rpmfusion repositories enabled. The only one of the 3 repositories in each file enabled was the first one.
I then added priority listing to all the repositories on Rosalba. I set CentOS-Base and related to priority=1. I set CentOS-Media.repo priority to 1 (although it is disabled - just to head off future problems). I set all epel related to priorities to 20. I set all rpmforge related priorities to 10. I set all rpmfusion related priorities to 30, and left the first repo in rpmfusion-free-updates and rpmfusion-nonfree-updates were enabled. All other rpmfusion testing repositories were disabled by me.
I then had to by hand downgrade expat to expat-1.95.8-8.3.el5_4.2.x86_64 (the rpmforge version). I also removed and reinstalled x264.x86_64. Lastly I removed and reinstalled lyx. yum update was then run and completed successfully.
I installed yum-priorities on Allegra and made all CentOS-Base repositories priority 1. I similarly made the still disabled CentOS-Media priority 1. I made all epel related repos priority 20. I made all lscsoft repos priority=50 (not sure why its on Allegra and none of the other ones). I made all rpmforge priorities 10. I then ran "yum update" which updated 416 packages.
So basically all the Centos control room machines are now using the following order for repositories:
CentOS-Base > rpmforge > epel > (rpmfusion - rosalba only) > lscsoft (allegra only)
I'm not sure if rpmfusion and lscsoft are necessary, but I've left them for now. This should mean "yum update" will have far fewer problems in the future.
I added the following repos which I found on allegra to megatron and then did a 'yum install sshfs' on both machines:
-rw-r--r-- 1 root root 428 Feb 12 16:47 rpmforge.repo
-rw-r--r-- 1 root root 684 Feb 12 16:47 mirrors-rpmforge
-rw-r--r-- 1 root root 1054 Feb 12 16:47 epel-testing.repo
-rw-r--r-- 1 root root 954 Feb 12 16:47 epel.repo
-rw-r--r-- 1 root root 626 Feb 12 16:47 CentOS-Media.repo
-rw-r--r-- 1 root root 1869 Feb 12 16:47 CentOS-Base.repo
-rw-r--r-- 1 root root 179 Feb 12 16:47 adobe-linux-i386.repo
This also required me to import the rpmforge GPG key:
sudo rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
For several of the channels on the PEM ADCU, zeros are occuring at the same time. Does anyone know why that might happen or how to fix it?
Added zita to the martian host table, and configured his network accordingly:
zita A 192.168.113.217
I installed 'nfs-client' on zita (the StripTool terminal). It now has mounted all the shared disks, but still can't do StripTool since its a 32-bit machine and our StripTool is 64.
I'll finish the rest of the config to turn it into a full-fledged workstation tomorrow.
Here is a comparison of the response of various DoFs in our various RFPD sensors for two different CARM offsets. Even in the case of the smaller CARM offset of ~1kHz, we are several linewidths away from the resonance. Need to do some finesse modeling to make any meaningful statement about this - why is the CARM response in REFL11 apparently smaller for the smaller CARM offset?
If you mistrust my signal processing, the GPS times for which I ran the sensing lines are:
CARM offset = ~30kHz (arm transmission <0.02) --- 1257064777+5min
CARM offset = ~1kHz (arm transmission ~5) --- 1257065566+5min
There seems to be stronger-than-expected coupling between CARM and the 3f sensors.
