At my lab, with NFS accounts, some machines have been upgraded to
Debian 8, and I get regular hangs on these machines, while they
never occurred before on the same machine and still never occur
on a machine that is still under Debian 7.
This happens with one of my scripts, which does a lot of "mv",
and more often when the target has just been modified from another
machine.
A strace showed that it is the "rename" system call that hangs:
52026 0.000208 execve("/bin/mv", ["mv", "-v", "ssh/ssh-reconfigure", "/home/vlefevre/bin/ssh-reconfigu"...], [/* 112 vars */]) = 0
[...]
52026 0.000097 rename("ssh/ssh-reconfigure", "/home/vlefevre/bin/ssh-reconfigure") = 0
52026 15.057725 lseek(0, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek)
52026 0.000189 close(0) = 0
52026 0.000175 close(1) = 0
52026 0.000093 munmap(0x7fd5a610b000, 4096) = 0
52026 0.000079 close(2) = 0
52026 0.000106 exit_group(0) = ?
52026 0.000307 +++ exited with 0 +++
The NFS server isn't particularly loaded.
Has anyone seen a problem like that?
Where does it come from?
And why does it affect only Debian 8 machines? A new bug?
