Greetings,
We tried testing with path_checker readsector0 end directio but we get
some strange behavior eg the checker used is always tur!!
So if we create a device entry special for IBM 2145 and define as
path_checker directio or readsector0 we still see in the message file
tur messages:
Jul 23 08:09:00 kl11071i multipathd: 65:0: tur checker reports path is
down
Jul 23 08:09:00 kl11071i multipathd: 65:16: tur checker reports path is
down
Jul 23 08:09:00 kl11071i multipathd: 65:32: tur checker reports path is
down
Jul 23 08:09:00 kl11071i multipathd: 65:48: tur checker reports path is
down
Jul 23 08:09:00 kl11071i multipathd: 65:80: tur checker reports path is
down
Jul 23 08:09:00 kl11071i multipathd: 65:96: tur checker reports path is
down
Jul 23 08:09:00 kl11071i multipathd: 65:112: tur checker reports path is
down
Oure multipath.conf file is:
defaults {
user_friendly_names yes
}
devices{
device {
vendor "IBM"
product "2145"
path_grouping_policy group_by_prio
getuid_callout "/sbin/scsi_id -g -u -s"
prio_callout "/sbin/mpath_prio_alua %d"
path_checker readsector0
failback immediate
}
}
Did someone see this behavior before? Or are we doing something wrong?
We are using device-mapper-multipath-0.4.5-27.el4_6.3 on a rhel4.6
system.
Kind regards,
Menno
