[gpfsug-discuss] Request for folks using encryption on SKLM, run a word count

[IBM Spectrum Scale]

Hi Eric,

Please help me to understand your question. You have Spectrum Archive and
Spectrum Scale in your system, and both of them are connected to IBM SKLM
for encryption. Now you got lots of error/warning message from SKLM log.
Now you want to understand which component, Scale or Archive, makes the
SKLM print those error message, right?

Regards, The Spectrum Scale (GPFS) team

We have spectrum archive with encryption on disk and tape.   We get maybe a
100 or so messages like this daily.  It would be nice if message had some
information about which client is the issue.

We have had client certs expire in the past.  The root cause of the outage
was a network outage...iirc the certs are cached in the clients.

I don't know what to make of these messages...they do concern me.  I don't
have a very good opinion of the sklm code...key replication between the key
servers has never worked as expected.

  I've gone round and round with IBM SKLM support over the last year on
  this and it just has me wondering.  This is one of those "morbidly
  curious about making the sausage" things.

  Looking to see if this is a normal error message folks are seeing.  Just
  find your daily, rotating audit log and search it.  I'll trust most folks
  to figure this out, but let me know if you need help.
  Normal location is /opt/IBM/WebSphere/AppServer/products/sklm/logs/audit
  If you are on a normal linux box try something like:  "locate
  sklm_audit.log |head -1 |xargs -i grep "Server does not trust the client
  certificate" {} |wc "  or whatever works for you.   If your audit log is
  fairly fresh, you might want to check the previous one.   I do NOT need
  exact information, just 'yeah we get 12million out a 500MB file' or ' we
  get zero', or something like that.

   Mostly I'm curious if folks get zero, or a large number.  I've got my
  logs adjusted to 500MB and I get 8 digit numbers out of the previous
  log.   Yet things work perfectly.    I've talked to two other SS sites I
  know the admins personally, and they get larger numbers than I do. But
  it's such a tiny sample size! LOL

  Apologies for the message formatting issues.  Outlook fought tooth and
  nail against sending it with the path as is, and kept breaking my
  paragraphs.
