*** Zer0Byte__ has joined #openstack-cinder19:34
jgriffith_e0ne: I can crush the single disk performance with iSCSI and LVM19:35
e0nejgriffith_: cool, thanks!19:35
jgriffith_e0ne: one thing that we do that people may not now is we create everything as a linear LV19:35
*** dustins has joined #openstack-cinder19:35
jgriffith_e0ne: if you add in LVM striping you can boost that performance significantly.  I'm also going to compare md-raid and lvm-striped w/mirroring configs for reliability concious folks19:36
e0nejgriffith_: we've got one tool to test performance: https://github.com/Mirantis/disk_perf_test_tool19:37
e0nejgriffith_: maybe it will be helpful for you19:37
jgriffith_e0ne: oh cool, I'll check it out19:37
e0nejgriffith_: one of the slowest LVM part - is's a tgtd, IMO19:38
*** kaisers_ has joined #openstack-cinder19:38
e0nejgriffith_: it causes high CPU load on my envs19:38
eharneye0ne: why use tgtd at all instead of LIO at this point?19:39
e0neeharney: it's a good question19:39
e0neeharney: the answer is: because it's our default target19:39
e0nelet's change it to LIO19:39
eharneyfine by me19:39
jgriffith_eharney: yeah, noone is arguing with you on that I don't think19:40
jgriffith_e0ne: the trick is how to convert/migrate on upgrades19:41
*** alonmarx has quit IRC19:41
e0nejgriffith_: good point. I'll try to take a look on it and how to not a break grenade19:41
jgriffith_e0ne: I don't think the same way I did IET will work in this case, but certainly worth looking at19:42
e0nehopefully, I'll do it before the Summmit19:42
eharneyi suspect it's tricky because you will have to detach all volumes to do it19:42
jgriffith_e0ne: Nice!!!19:43
jgriffith_eharney: yeah, and there's also something funky that happens with tgt running if you try and add in LIO as I recall the last time I tried it19:43
eharneyjgriffith_: yeah, my first thought is that things will go awry because LIO can't spin up an iscsi target on port 3260 until tgtd no longer has one19:43
jgriffith_eharney: EXACTLY!!!19:44
jgriffith_eharney: that's bitten me a couple of times now and it's very annoying19:44
jgriffith_eharney: "Failed: port 3250 is in use"  DOHHHHH!19:44

* e0ne hates upgrades19:45
