Please note: This documentation is for OSG 1.2. While we still provide critical security updates for OSG Software 1.2, we recommend you use OSG Software 3 for any new or updated installations. We are considering May 31, 2013 as possible OSG 1.2 End of Life (EOL).
Not at present. Developers are working on it.
No. In order to perform file operations (reading, concatenating, etc), you must copy files locally, manipulate/use them and copy them back to storage location.
No. There is no way to find out pool name on client side.
Recommended way is to clean out all the replicas from the companion DB via postgres, then run "pnfs register" on each pool via the admin interface.
Send an email to email@example.com
to get the solution. It is not posted here because of its critical nature.
No. Only Storage Element Admin can do so.
Use the "pacman -get OSG:client" command.
This can be obtained by having a few users belong to a special group/role within your VO and then using standard unix like permissions on the storage locations in question for the user to which this VO/group/role gets mapped to.
At present, nothing UNLESS you explicitly run a space cleaner tool which cleanups expired space reservations.
Yes. Credentials are delegated to pools so that they can act as clients when receiving data in pull mode or delivering
data in push mode. See slides 14 and 16 of https://srm.fnal.gov/twiki/pub/SrmProject/SrmPresentations/SRMDesign.pdf
. Therefore in these cases they
need host certificates.
Following different approaches have worked for admins in the past. However, you are responsible for making sure that this does not break other things on the system
- In /etc/hosts, map both the public and private host names to the public IP address.
- Swap IP address definitions for eth0 and eth1.
- Check that the public/private NICs occupy the same slots of the PCI bus on the doors that don't work as they do on the doors that do work and physically swap them if different.
- amount of available pool space for link group Reserved Space
- amount of space you reserved Available Space
- amount of space available for reservation
(Available space=Free Space-Reserved Space)

Yes, we highly recommend it. There have been cases of slow response from commands like srmcp, srmls when nodes were running different dCache versions.
Referring to the following sections of the Postgresql 9.0 documentation:
(scroll to “bytea_output(enum)”)
“The bytea type supports two external formats for input and output: PostgreSQL?
's historical "escape" format, and "hex" format. Both of these are always accepted on input. The output format depends on the configuration parameter bytea_output; the default is hex. (Note that the hex format was introduced in PostgreSQL?
9.0; earlier versions and some tools don't understand it.) “
So try this on the Postgresql 9.0.2 version of the Chimera DB:
[root@head02 ~]# env PGOPTIONS='-c bytea_output=escape' /usr/pgsql-9.0/bin/psql -p 5431 -U postgres
Type "help" for help.
postgres=# \c chimera
You are now connected to database "chimera".
chimera=# select * from t_tags_inodes limit 2;
itagid | imode | inlink | iuid | igid | isize | ictime | iatime | imtime |ivalue

Things seem to work now. I just need to find out how to set this “DB” wide (perhaps in postgresql.conf). Yes there is a setting:
#bytea_output = ‘hex’
Changing this to
bytea_output = ‘escape’
And restarting Postgresql 9.0.2 seems to work
