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
