Dear All,
I have been using ovirt for many years. I've got six servers , two
HPE MSA storage and a fiber channel network with two Brocade 8/20q.
oVirt has got two domain storage, one volume for each MSA. Now I
have only one MSA online. As you know multipath was configured
throught vdsm.
This is the output of the multipath command from one of the servers:
[root@infm-vm04 etc]# multipath -ll
3600c0ff0003c465b6510f85b01000000 dm-2 HPE ,MSA 2050 SAN
size=14T features='1 queue_if_no_path' hwhandler='0' wp=rw
|-+- policy='service-time 0' prio=1 status=active
| `- 2:0:0:0 sdc 8:32 active ready running
|-+- policy='service-time 0' prio=1 status=enabled
| `- 1:0:0:0 sdb 8:16 active ready running
|-+- policy='service-time 0' prio=1 status=enabled
| `- 2:0:1:0 sdd 8:48 active ready running
`-+- policy='service-time 0' prio=1 status=enabled
`- 1:0:1:0 sde 8:64 active ready running
With this setup I think there is an active path and the other is in
standby state.
So, Id like to know if ovrt support active-active mode and how can
I make
this settings ?
This is the current multipath.conf
defaults {
polling_interval 5
no_path_retry 4
user_friendly_names no
flush_on_last_del yes
fast_io_fail_tmo 5
dev_loss_tmo 30
max_fds 4096
}
blacklist {
protocol "(scsi:adt|scsi:sbp)"
}
devices {
device {
all_devs yes
no_path_retry 4
}
}
Thanks a lot.
Bye
Enrico
