Hello,
I have an f18 setup with all-in-one ovirt nightly.
The system has two disks /dev/sda and /dev/sdb

I notice that in ovirt seup a multipath.conf file has been written:


# RHEV REVISION 0.9

defaults {
    polling_interval        5
    getuid_callout          "/lib/udev/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
}

devices {
device {
    vendor                  "HITACHI"
    product                 "DF.*"
    getuid_callout          "/lib/udev/scsi_id --whitelisted
--replace-whitespace --device=/dev/%n"
}
device {
    vendor                  "COMPELNT"
    product                 "Compellent Vol"
    no_path_retry           fail
}
}

I get many of these errors in messages

Could the be related?

$ sudo multipath -l
Jan 10 23:49:27 | multipath.conf +5, invalid keyword: getuid_callout
Jan 10 23:49:27 | multipath.conf +18, invalid keyword: getuid_callout

Is this necessary for my internal disks or not?
Otherwise from

[g.cecchi at tekkaman ~]$ sudo /lib/udev/scsi_id --whitelisted
--replace-whitespace --device=/dev/sda
35002538043584d30

[g.cecchi at tekkaman ~]$ sudo /lib/udev/scsi_id --whitelisted
--replace-whitespace --device=/dev/sdb
35000cca313d8b629

I would put this in my multipath.conf:

blacklist {
       wwid 35002538043584
       wwid 35000cca313d8b629
}


Thanks,
Gianluca
