We have over 14 million files stored without any problems.

To get a count of files stored by node and filespace use 'q occ' from the
admin commandline client.  Node and filespace are optional; if you can
capture the output, you can use some other tool to get a count of all files
in the server.  Do 'help query occ' for the details.

Several of our people went to LISA in Chicago this year.  One rumor that
came back from LISA was that ADSM failed, silently and hard, when it hit a
million files stored.  The rumor goes on, quoting IBM as saying they're not
going to fix it.  This is now part of the received wisdom around our site;
frankly, I find it hard to believe based on the good experiences I have had
setting up ADSM with 3494 libraries and 3590 drives.

My guess is that the million file limit came from somone setting up an HSM
client with only a million inodes, and when it hit a million files it quit
accepting new ones.  Either that or someone set up their db too small.

I would be interested to hear from sites that are storing more than a
million files, especially those that are storing >1E6 files via the HSM
client.  Also, if this story sounds familiar, and you know the details, I
would be interested to hear about them as well.  Also: is there an easy way
to query a filespace or storage pool to see how many files are stored in
that filespace/storage pool?

Thanks,
