--- Begin Message ---Package: nfs-kernel-server Version: 1:2.8.2-1+b1 Severity: grave Justification: causes non-serious data loss X-Debbugs-Cc: invernom...@paranoici.org Dear maintainers, I encountered a big issue, while upgrading package 'nfs-kernel-server' on the box where the NFS server runs (the clients run on the compute nodes of an HPC cluster). The upgrade: [UPGRADE] nfs-kernel-server:amd64 1:2.8.2-1 -> 1:2.8.2-1+b1 got stuck at [...] Setting up nfs-kernel-server (1:2.8.2-1+b1) ... It looks like it was stuck at the restart of the systemd service: # systemctl status nfs-kernel-server.service ● nfs-server.service - NFS server and services Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled; prese> Drop-In: /run/systemd/generator/nfs-server.service.d └─order-with-mounts.conf Active: activating (start-pre) since Tue 2025-01-21 12:40:52 CET; 10min ago Job: 97667 Invocation: ced460d410fe4059b9e8781b35340d70 Docs: man:rpc.nfsd(8) man:exportfs(8) Cntrl PID: 249039 (exportfs) Tasks: 3 (limit: 154102) Memory: 680K (peak: 2.5M) CPU: 10ms CGroup: /system.slice/nfs-server.service ├─239857 /usr/sbin/nfsdctl threads 0 ├─239918 /usr/sbin/exportfs -au └─249039 /usr/sbin/exportfs -r There was a 'nfsdctl' process in uninterruptible sleep (D): $ ps -eldaf | grep nf[s] 4 D root 239857 1 0 80 0 - 847 - 12:07 ? 00:00:00 /usr/sbin/nfsdctl threads 0 5 S root 247511 1 0 80 0 - 1375 - 12:35 ? 00:00:00 /usr/sbin/nfsdcld After about 30 min, since trying to kill PID 239857 obviously had no effect, and I could not find any other strategy to restart nfs-kernel-server.service, I had to reboot the box, thus causing many problems to all the NFS clients. After reboot, I could issue: # aptitude --purge-unused safe-upgrade which finally completed the upgrade (fixing the nfs-kernel-server package, which was left in a partially configured state). I have never seen anything like this before, and I have upgraded nfs-kernel-server and related packages on Debian machines for quite a long time. Anyway, this should *not* happen during a system upgrade with aptitude or apt! I don't know whether bug [#992661] is related or not. [#992661]: <https://bugs.debian.org/992661> By looking at /var/log/kern.log , I see that a kernel BUG was traced at the time when the 'nfsdctl' process got stuck in D state. See the attached kern.log snippet. Please investigate and fix the issue as soon as possible. I really hope we can prevent this from happening again!
