sPHENIX HCal discussion

HCalers,

Stefan had called me to ask if we could find more disk space for the 912
DAQ machine, as space was getting tight. There is no easy way to put
more disk into the actual "sphenixdaq" machine, it's old and all. I put
an additional disk in the gateway machine, and NFS-mounted it on the DAQ
machine as /data (same name on the gateway).

Sorry that I inadvertently kicked Daniel off; I had checked that no one
was logged in but he must have sneaked past while I was getting there.

You have now

> ...

> hcal912gw.phy.bnl.local:/data on /data type nfs

I made directories

> [phnxsa@sphenixdaq ~]$ ls /data/phnxsa/912/
> cosmics  junk  test
>
and modified the the setup script /homesa/phnxsa/hcal912/bin/setup_912.sh

to read


> # activate this for new disk DEST=/data/phnxsa//912
> DEST=/scratch/data/912

> rcdaq_client daq_define_runtype test     $DEST/test/test_%08d-%04d.prdf
> rcdaq_client daq_define_runtype cosmics 
> $DEST/cosmics/cosmics_%08d-%04d.prdf

so right now it is still all as it used to be.

Comment the currently active "DEST=" line, and un-comment the other one,
reload, and you'll write to the new disk.

I did set the filerule manually and wrote a junk file to the new place.
All good.

BTW, just to state the obvious, if you transfer data to the RCF or so,
please do from the gateway for more efficiency, as that's where the data
are physically hosted now. You have 8 TB.

Have fun!
