correlate with the NFSD misbehavior?
There was a big change: Most clients (>100) were upgraded from Debian 11 to Debian 12 within the last couple of months. A big chunk of about 40 hosts have been upgraded on May 21st. This included the kernel upgrade to 6.1.xx, and the upgrade of the "nfs-common" package from version 1.3.4 to 2.6.2. The current nfs-common package provides these tools: /sbin/mount.nfs /sbin/mount.nfs4 /sbin/rpc.statd /sbin/showmount /sbin/sm-notify /sbin/umount.nfs /sbin/umount.nfs4 /usr/sbin/blkmapd /usr/sbin/mountstats /usr/sbin/nfsconf /usr/sbin/nfsidmap /usr/sbin/nfsiostat /usr/sbin/nfsstat /usr/sbin/rpc.gssd /usr/sbin/rpc.idmapd /usr/sbin/rpc.svcgssd /usr/sbin/rpcctl /usr/sbin/rpcdebug /usr/sbin/start-statd I have 3 clients with more recent kernel versions 5.10.209, 5.10.218 and 6.7.12. The 5.10.x hosts are running Debian 12 and this kernel for several months, but the host with 6.7.12 is running this kernel since May 16th. These "backports" kernels were installed for testing purposes. Would you recommend to downgrade these kernels to 6.1.90? As asked before, do you think the problem could be related to running nfsd inside an LXC container? Regards Harri
