[ovirt-users] LocalOnHost Multipath Blacklist Fails

[Duckworth, Douglas C]

Putting "blacklist" above "devices" seems to work:

defaults {
    polling_interval        5
    getuid_callout          "/sbin/scsi_id --whitelisted
--replace-whitespace --device=/dev/%n"
    no_path_retry           fail
    user_friendly_names     no
    flush_on_last_del       yes
    fast_io_fail_tmo        5
    dev_loss_tmo            30
    max_fds                 4096
}
blacklist {
    wwid "*"
    devnode "^sd(a|b)[0-9]"
}
devices {
device {
    vendor                  "COMPELNT"
    product                 "Compellent Vol"
    no_path_retry           fail
}
}


multipathd restart:

Dec 10 16:32:19 tulhv2p01 multipathd: --------shut down-------
Dec 10 16:32:19 tulhv2p01 multipathd: path checkers start up

No more syslog pollution!

Best
