I frequently change quorum on the fly on both our 4.x and 5.0 clusters during

You have sanity in the CCR to start with? (mmccr query, lsnodes, etc,etc)
Anything useful in the logs or if you drop debug on it? ('export DEBUG=1'and

Why not just configure a file placement policy using a non existent pool or a
bad encryption key to prevent files with non-printables characters from even
being created in the first place.

I know I've run into this before way back, but my notes on how I solved this
aren't getting the job done in Scale 5.0.5.8 and my notes are from 3.5. 😉
Anyone know a way to get a LIST policy to properly feed bad filenames into the
output or an external script?

This looks like a bad cable (or port). Trying re-seating the cable on both
ends, or replacing it to get to full Link Speed.
Re-run ibdiagnet to confirm or use something like 'ibportstate' to check it.

Replying to a 3 year old message I sent, hoping that in the last couple of
years that Scale has added some ILM extensions into the policy engine that I
have missed, or somehow didn't notice?

Ran into something a good while back and I'm curious how many others this

their SKLM server and reply with a rough count I'd appreciate it.

We also went with independent filesets for both backup (and quota) reasons for

I saw something EXACTLY like this way back in the 3.x days when I had a backend
storage unit that had a flaky main memory issue and some enclosures were
constantly flapping between controllers for ownership. Some NSDs were
affected, some were not. I can imagine this could still happen in 4.x a
Disregarding all the other reasons not to run it on the NSDs, many years of
rsync on GPFS has shown us it is ALWAYS faster from clients with reasonable
networks and no other overhead.

Interesting. We just deployed an ESS here and are running into a very similar
problem with the gui refresh it appears. Takes my ppc64le's about 45 seconds

I'm assuming that was a run in the foreground and not using QoS?
Our timings sound roughly similar for a Foreground run under 4.2.3.x. 1 hour
and ~2 hours for 100million and 300 million each. Also I'm assuming actual
file counts, not inode counts!
Background is, of course, all over the place
We use NHC here (Node Health Check) from LBNL and our SS clients are almost all
using NFS root. We have a check where we look for access to a couple of
dotfiles (we have multiple SS file systems) and will mark a node offline if the
checks fail.
Many things can contribute to the failure of a si
This is rather dependant on SS version.
So what used to happen before 4.2.2.* is that a client would be unable to mount
the filesystem in question and would give an error in the mmfs.log.latest for

This is a great idea. However there are quite a few other things to consider:
-max file count? If you need say a couple of billion files, this will affect
things.
-wish to store small files in the system pool in late model SS/GPFS?
-encryption? No data will be stored in the system pool so la
Along the same vein I've patched rsync to maintain source atimes in Linux for
