Ciao,
I am playing with a tape setup at CNAF, and I want to enable stagein support …
I have a simple xrootd.cfg (only relevant parts shown)
…
all.export / r nomig nocheck nodread stage
# Hosts allowed to use this xrootd cluster
cms.allow host *
#stagein stuff....
frm.xfr.copycmd out /bin/true 0
frm.xfr.copycmd in stats noalloc /opt/xrootd/bin/copy.sh $SRC $DST
frm.xfr.copymax 200
# Keep this as a work-around for an xrootd bug
oss.localroot /storage/gpfs_tsm_cms/cms/
…
I have nomig since migrations will happen automatically … Instead I have put an explicit stage-in part:
frm.xfr.copycmd in stats noalloc /opt/xrootd/bin/copy.sh $SRC $DST
what happens is that is I request a file which does not exist (or exists only on tape), and xrdcp client waits with
130311 13:25:16 14110 Xrd: ReadPartialAnswer: Server [ds-202-08-37.cr.cnaf.infn.it:1094] answered [kXR_waitresp] (4006)
130311 13:25:16 14110 Xrd: WaitResp: Waiting response for 1800 secs.
and
/opt/xrootd/bin/copy.sh
in never invoked (i checked putting inside a lot of debug printout)..
Also, if I do
[root@ds-202-08-37 xrootd]# /etc/init.d/frm_xfrd start
[root@ds-202-08-37 xrootd]#
nothing happens … instead by doing by hand
frm_xfrd -l /var/log/xrootd/cms/xfrd.log -c /etc/xrootd/xrootd-clustered.cfg -k 5
I get some logging, but again no attempt of stagein:
