New page

This wiki page is intended to help admins debugging dCache issues.

=== Tracking pnfs id and pool for a specific file ===

*Login to the admin console
<pre>
[root@maite ~]# ssh -F /root/.ssh/dcache_admin_config admin@localhost

dCache Admin (VII) (user=admin)

[maite.iihe.ac.be] (local) admin >
</pre>

*Copy the file with <tt>dccp</tt> and check in <tt>PoolManager</tt> the status of the transfer. In our case, something is bad with <tt>pnfsid 000C00000000000000D4D6F8</tt>
<pre>
[maite.iihe.ac.be] (local) admin > cd PoolManager
[maite.iihe.ac.be] (PoolManager) admin > rc ls
000C00000000000000D4D6F8@0.0.0.0/0.0.0.0-*/* m=9 r=1 [<unknown>] [Suspended (pool unavailable) 08.19 10:01:01] {0,}
</pre>

*Another way to know the pnfsid of a file is to run:
<pre>
[maite.iihe.ac.be] (local) admin > pnfs map /pnfs/iihe/cms/ph/sc4/store/mc/2007/11/13/CSA07-tt0j_mT_70-alpgen-3545/0005/064A4D43-7DC3-DC11-B586-0030487C116E.root
000C00000000000000D4D6F8
</pre>

*Or yet another way, in <tt>PnfsManager</tt>
<pre>
[maite.iihe.ac.be] (PnfsManager) admin > pnfsidof /pnfs/iihe/cms/ph/sc4/store/mc/2007/11/13/CSA07-tt0j_mT_70-alpgen-3545/0005/064A4D43-7DC3-DC11-B586-0030487C116E.root
000C00000000000000D4D6F8
</pre>

*In <tt>PnfsManager</tt>, using the pnfsid you can locate the pool that stores physically the file by running:
<pre>
[maite.iihe.ac.be] (PnfsManager) admin > cacheinfoof 000C00000000000000D4D6F8
behar5_1
</pre>

*The command cd will not work to leave go back to admin
<pre>
..
</pre>

*Looking into each machine explicitly
<pre>
[beharX.iihe.ac.be] > ls /storage/[1,2,3]/pool/data/0011000000000000032CC250
</pre>

=== Setting the verbosity level of dCache ===
to increase the verbose level in the logs of dCache, go to /opt/d-cache/config/<br>
In this directory, there are a number of files ending in .batch. There is one per service.<br>
Open the file and adapt the printout level (default=2, increase to 5)<br>
Then restart the associated dCache service.
