NFSD: attempt to initialize ... client tracking ... in a container #48

Open phlax opened 4 years ago

phlax commented 4 years ago

I see logs like

Jun  1 08:13:58 localhost kernel: [   84.417179] NFSD: attempt to initialize umh client tracking in a container ignored.
Jun  1 08:13:58 localhost kernel: [   84.417196] NFSD: attempt to initialize legacy client tracking in a container ignored.
Jun  1 08:13:58 localhost kernel: [   84.417197] NFSD: Unable to initialize client recovery tracking! (-22)
Jun  1 08:13:58 localhost kernel: [   84.417198] NFSD: starting 90-second grace period (net f0000233)

You can see these logs on travis here

Im thinking its the failure to initialize nfs tracking that is causing the grace period to come into effect.

kick #44

the logs are in the host syslog not in the container

for ref there is some discussion of similar logs here - https://bugzilla.redhat.com/show_bug.cgi?id=1700098

once the grace period expires, the container comes up and nfs exports as expected

im thinking this issue is not related to the grace period, and may well not be a problem. Not sure how to test the client-tracking
