Hi,
I would like to run my ideas by this list about multipathing and the results
as far as storage speed is concerned.
I'm using multipathing to two iSCSI targets pointing to the same storage. It
was my understanding that this provides for network path redundancy (and it
does, I tested this) but also for added speed.
I did some tests with Bonnie++ however while both paths were active and one
path was down and the results are basically the same.
Am I assuming wrong things? Or have I configured things wrong?
This is my config for now:
defaults {
udev_dir /dev
polling_interval 10
selector "round-robin 0"
path_grouping_policy multibus
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio const
path_checker directio
rr_min_io 100
max_fds 8192
rr_weight priorities
failback immediate
no_path_retry 5
user_friendly_names no
}
blacklist {
wwid 26353900f02796769
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z][[0-9]*]"
devnode "^cciss!c[0-9]d[0-9]*[p[0-9]*]"
device {
vendor DEC.*
product MSA[15]00
}
}
multipaths {
multipath {
wwid
1494554000000000000000000010000000000000002000000
alias lx03
}
multipath {
wwid
1494554000000000000000000010000000100000002000000
alias ws033
}
multipath {
wwid
1494554000000000000000000010000000200000002000000
alias ms01
}
}
Thank you!!
B.
