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 runningWith 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
