Hello to all
I'm trying to configure iscsi target with two proxmox hosts and want to
enhance link to storage as much as posible.
multipath command says:
root@pmx01:~# multipath -ll
root@pmx01:~# multipath
Aug 22 20:30:21 | sdc: alua not supported

So, my initiators obviously do not support alua and after some research
I've found that mpath_prio_alua file does not exist on the host .
I have multipath-tools installed (and reinstalled) but nothing changed.
Native location "should" be :
root@pmx01:~# ls /sbin/mpath_prio_alua -al
ls: cannot access /sbin/mpath_prio_alua: No such file or directory
my device part from multipath.conf :
device {
vendor "LIO-ORG"
product "*"
#path_grouping_policy group_by_prio
path_grouping_policy multibus
path_checker tur
# getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
getuid_callout "/lib/udev/scsi_id -g -u -d /dev/%n"
prio_callout "/sbin/mpath_prio_alua /dev/%n"
prio "alua"
path_selector "round-robin 0"
hardware_handler "1 alua"
rr_weight uniform
rr_min_io 2
failback immediate
}
}
Has anybody used multipath with iscsi ? ... and how could I switch it on ?
thank you very much in advance
