    Red face mdadm email alerts - probably a really dumb question

    hi

    i've got mdadm 2.3.1 monitoring my RAID 1 array

    [root@localhost ~]# mdadm -Q --detail /dev/md1
    /dev/md1:
    Version : 00.90.03
    Creation Time : Mon May 15 23:41:35 2006
    Raid Level : raid1
    Array Size : 195101312 (186.06 GiB 199.78 GB)
    Device Size : 195101312 (186.06 GiB 199.78 GB)
    Raid Devices : 2
    Total Devices : 2
    Preferred Minor : 1
    Persistence : Superblock is persistent

    Update Time : Tue May 16 14:21:35 2006
    State : clean
    Active Devices : 2
    Working Devices : 2
    Failed Devices : 0
    Spare Devices : 0

    UUID : 06947d7f:be3d43d3:c7da6383:ed9a96c8
    Events : 0.7666

    Number Major Minor RaidDevice State
    0 8 2 0 active sync /dev/sda2
    1 8 18 1 active sync /dev/sdb2
    no problems as far as i can see

    i've got a single LVG with 3 LVs sitting on top of the RAID

    i can't get email alerts generated !

    i've got myemail@myISP.com in mdadm.conf - there is no internal email server on the network and this RAID sits in a PDC/fileserver which will run headless in due course, so alerts need to go out via my ISP

    by my reckoning:

    mdadm -monitor /dev/md1 --test

    should generate a test email - nothing doing

    terminal just hangs with

    mdadm: Monitor using email address "lmyemail@myISP.com" from config file

    and i lose the # prompt

    email works fine in evolution - send and receive no probs

    am i doing something REALLY dim ????

    help

    Just to test I ran:

    mdadm --monitor -1 -m myname@myisp.com /dev/md0 -t

    Which sends a test message to my mailbox.

    Without the -1 (which means run once) mdadm --monitor will keep running until it is killed (or sent an interupt signal), but it still sends an email periodically.

    I suggest you put the something like this in your crontab:

    0,20,40 * * * * mdadm --monitor -1 -m yourname@yourisp.com -scan

    To have a scan performed every 20 minutes.

    yes - when i added --daemonise to my command it spawns a child process and i get the # back

    all good learning

    i'm working with my ISP to try to get around the 'spam killing' they have set up that prevents them directing mail from localhost.localdomain

    thanks
