I’ve also voted and commented on the ticket, but I’ll say this here: If the
amount of time I spent on this alone (and I like to think I’m pretty good with
this sort of thing, and am somewhat of a systemd evangelist when the
opportunity presents itself), this has caused a lot of people a lot of
Has anyone confirmed this? At one point, I mucked around with this somewhat
endlessly to try to get something sane and systemd-based to work and ultimately
surrendered and inserted a 30 second delay. I didn’t try the “check for the
presence of a file” thing as I’m allergic to that sort of thing
We use callbacks successfully to ensure Linux auditd rules are only loaded
after GPFS is mounted. It was easy to setup, and there's very fine-grained
events that you can trigger on:

Hi Venkat,
The AFM fileset becomes totally unresponsive from all nodes within the cluster
and the only way to resolve it is to do a "mmshutdown" and wait 2 mins, then
"mmshutdown" again as it cannot really do it the first time.. and then a
"mmstartup" then all is back to normal and AFM is
There’s an RFE related to this: RFE 125955
(https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe_ID=125955)
I recommend that people add their votes and comments there as well as
discussing it here in the UG.

Hi,
a gpfs.mount target should be automatically created at boot by the
systemd-fstab-generator from the fstab entry, so no need with hackery like

Hi,
What is lock down of AFM fileset ? Are the messages in requeued state and
AFM won't replicate any data ? I would recommend opening a ticket by
collecting the logs and internaldump from the gateway node when the
replication is stuck.
You can also try increasing the value of
Have you looked a the mmaddcallback command and specifically the file system mount callbacks?

Hi All,
Can anyone share some thoughts on how to tune AFM for stability? at the moment
we have ok performance between our sites (5-8Gbits with 34ms latency) but we
encounter a lock down of the cache fileset from week to week, which was day to
day before we tuned below settings.. is there any
