Description Kiyoshi Ueda 2006-05-23 14:22:32 EDT
Description of problem:
Logout doesn't complete because dmeventd doesn't release terminal
after activate a LV on the remote terminal.

Version-Release number of selected component:
device-mapper-1.02.07-2.0.RHEL4 (RHEL4 U4 pre-beta)

How reproducible:

Steps to Reproduce:
 1. ssh login to a host.
    And execute the following commands on the remote terminal.
 2. Prepare a VG which has more than 2 PVs.
 3. Create a mirror LV from the VG.
      # lvcreate -L 12m -n lv0 -m 1 vg0
 4. Logout from the host.

Actual results:
Shell prompt doesn't return.

Expected results:
Shell prompt should return.

Additional info:
In the dmeventd/dmeventd.c:daemonize(), related codes seems to be

static int daemonize(void)
        if (chdir("/"))
                return -EXIT_CHDIR_FAILURE;

/* FIXME: activate again after we're done with tracing.
        if ((close(STDIN_FILENO) < 0) ||
            (close(STDOUT_FILENO) < 0) ||
            (close(STDERR_FILENO) < 0))
                return -EXIT_DESC_CLOSE_FAILURE;

        return 0;
