NFS case study. - obsd server mounts LAN resource via NFS - the NFS server is a NAS running Alt-F firmware version 1.0 with working ssh but without sudo; - the NFS link does not respond - all obsd related processes hang into D state, including command like ls, df, and reboot. - kill -9 does not work: the kernel locked them - umount -f does not work - reboot kills the server: tried locally, it hangs, forever - obsd hard reset not possible: it sits overseas, without manpower
I need fresh ideas to unlock the kernel ... locked processes and kill the nfs link. Sent from ProtonMail Mobile
