Hello, Recently, when I execute 'nfsserver stop' to stop nfsd service, I find that nfsd threads cannot be killed.
> > # nfsserver stop > stopping statd: done > stopping mountd: done > stopping nfsd: ..........failed > using signal 9: > ..........failed > I noticed that nfsserver script uses 'start-stop-daemon --stop --quiet --signal 1 --name nfsd' to stop nfsd service, which works by sending a signal to nfsd threads. And I have identified that this issue was caused by the following linux patch: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=7229200f68662660bb4d55f19247eaf3c79a4217 This patch said "nfsd stops allowing signals and we don't check for their delivery any more" and it recommends using /proc/fs/nfsd/threads instead of sending signals, for example, "echo 0 > /proc/fs/nfsd/threads" will stop all nfsd threads. I would like to know if this issue a problem need to be fixed? Best regards. Liyuan
