hammer streaming seems stop working for a while

[Sepherosa Ziehau]

Hi all,

I just noticed today, my hammer back mechanism seems stop working for a while.

The output of mount on the backup machine:
ROOT on / (hammer, local, noatime)
devfs on /dev (devfs, local)
/dev/serno/3PT023B3.s1a on /boot (ufs, local, noatime)
REPOS on /repos (hammer, local, noatime)
/repos/pfs/@@-1:00007 on /var (null, local)
/repos/pfs/@@-1:00003 on /tmp (null, local)
/repos/pfs/@@-1:00006 on /usr (null, local)
/repos/pfs/@@-1:00001 on /usr/obj (null, local)
/repos/pfs/@@-1:00005 on /var/crash (null, local)
/repos/pfs/@@-1:00004 on /var/tmp (null, local)
/repos/pfs/@@-1:00002 on /usr/src (null, local)
/repos/pfs/@@0x00000004f3766630:00009 on /backup/sephe/home (null,
local, read-only)
/repos/pfs/@@0x00000004f3766630:00008 on /backup/sephe/opt (null,
local, read-only)
/repos/pfs/@@-1:00010 on /backup/cold (null, local)
procfs on /proc (procfs, local)

/backup/sephe/home and /backup/sephe/opt is the slave.

On my laptop, I run:
hammer mirror-stream /opt root at enigma:/backup/sephe/opt
hammer mirror-stream /home root at enigma:/backup/sephe/home

And on the backup machine, I got many:
HAMMER(REPOS) Creating a PFS from non-root PFS is not allowed
in dmesg

It seems the above line is logged each time, the hammer mirror-stream
runs on my laptop.

I don't know when it started.

Thanks,
sephe
