Public bug reported: Trying to use kernel nfs server in containers generally works, but generates dmesg warnings as follows:
[ 23.392559] NFSD: attempt to initialize umh client tracking in a container ignored. [ 23.395065] NFSD: attempt to initialize legacy client tracking in a container ignored. [ 23.395085] NFSD: Unable to initialize client recovery tracking! (-22) [ 23.395106] NFSD: starting 90-second grace period (net f00005fd) On reboot clients do indeed hang for the grace period. >From the description here .. https://man7.org/linux/man-pages/man8/nfsdcld.8.html .. it seems that modern kernels in combination with nfsdcld from modern nfs-utils can avoid this problem - is there any chance we could build and install it? It looks like it might have a sqlite dependency so possibly needs splitting off into a separate package. ** Affects: nfs-utils (Ubuntu) Importance: Undecided Status: New ** Description changed: - Trying to use kernel nfs server in containers generally workers, but + Trying to use kernel nfs server in containers generally works, but generates dmesg warnings as follows: [ 23.392559] NFSD: attempt to initialize umh client tracking in a container ignored.
