For iscsi we do not support what you want to do. You would normally give each NIC port a IP, then create a iscsi target portal for each NIC port. Then you would have the initiator side do round robin over those iscsi portals. We do not support that with the upstream kernel and this project right now. SUSE ships a product that they support this type of config on. If you want to do that, you would have to contact them for details on how to get the kernel or do some googling, because I am not sure. I think it might just be in the free distro though.
For the ceph side, in this doc:
https://docs.ceph.com/docs/master/rados/configuration/network-config-ref/
it says:
For this reason, we generally recommend that dual-NIC systems either be configured with two IPs on the same network, or bonded.
Posting to the ceph users list is probably the best option for this type of questions, because I do not have any experience with this type of config in a real world setup.

This error means the iscsi target is sending commands to the ceph cluster, but it is taking over 30 seconds.
That bonding interface seems to have a lot of drops. Are you using that for ceph? If so then it is probably related to why we are getting timeouts when trying to access the ceph image.
The ext4 errors are a little odd though. Are you using ext4 for the root partition?
from ceph-iscsi.
hi
thanks for response
sorry that I'm late
i was sick and was resting
The ext4 errors are a little odd though. Are you using ext4 for the root partition?
yes but I think something in kernel is causing this problem and i suspect driver issue for dl380 G7
I just removed all bondings in my cluster and will report its behavior today
from ceph-iscsi.
hi again
sorry for the delay
I have been tweaking network section of my cluster
I have a question about network and it may not be related to iscsi but
how can I ditch bounding and use all my network adapters for higher throughput?
I have 2 nexus 3k switches and the funny thing is when I bound my adapters lcap won't go up except when I chose src-dst-ip-gre for my hashing policy and when it goes up I don't have a good experience
I have used teaming and bound and disabled NetworkManager but the same problem occurs
this is my network card https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c03572669
in general, how can I use multiple interfaces to maximize throughput?
should I forget about the age of my hardware and driver compatibility issues?
also, I can't thank you enough for your great work
from ceph-iscsi.
thank you so much for your time and help
sorry for the trouble but im trying to add new target to the second ip address
can i set HA to not show Failed: Clients can not be defined until a HA configuration has been defined(>2 gateways) ?
i don't want to add second gateway
have a great time till eternity
from ceph-iscsi.
hi
i did add new target to iscsi gateways
ill appreciate if you could comment on this

and i get this error in adding same disks

hi
i decided to add the second gateway to the ISCSI and second interface, the above log is resolved
and without creating iscsi portal VMWare has discovered second interface and now has active io on it
but the strange thing is the tcmu_rbd_handle_timedout_cmd still occurs

are you saying i can't use 2 interfaces and get my throughput up for 1 lun?
as I googled ceph-iscsi cant add 2 ip addresses to the same hostname
bound is not good for iscsi and is not recommended
from ceph-iscsi.
can i set HA to not show Failed: Clients can not be defined until a HA configuration has been defined(>2 gateways) ?
In /etc/ceph/iscsi-gateway.cfg
add:
[config]
minimum_gateways = 1
from ceph-iscsi.
but the strange thing is the tcmu_rbd_handle_timedout_cmd still occurs
If you are seeing those errors, it's normally because commands are taking too long on the OSD/network. You should check the ceph OSD and MON logs for errors, timeouts etc, and check the network.
from ceph-iscsi.
Could you tell me a little more about what you are trying to do?
Exporting a image through 2 different targets is not a common case, so I am not sure if it works. Are you just waning to export an image to 2 different ESXi hosts/initiators? If so, then you would want to use a hostgroup.
Could you tell me what type of workload you are doing when you see the command timeouts?
from ceph-iscsi.
what I'm trying is as follows
I have 2 bare-metal dl380g7 as iscsi gateway, each has 2x 10Gb FC/ethernet interface
I want to use both interfaces to get maximum throughput (20Gb)
uname -a
Linux ceph-client02 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
what I have done so far is
I have enabled jumbo frame 9000 cluster-wide
bounding (same result)
teaming (same result)
modes that I have tried are LACP Load balance and pretty much every possible scenario
I get timeouts every time
tested on Windows Linux and Vmware ESXI
tried on 3 different servers dl380g7 and g6 s
my network technician says I have no errors on switch interfaces and I should mention switches are brand new and part numbers are N3K-C3172-BA-L3
this is a trace happend on my iscsi server
it was using single ethernet with one ip address

Ah sorry, I just realized you were the same user as in
So basically the same thing where something is causing commands to timeout, then you hit a kernel bug which seems slightly different due to the different kernels (Bart's patch did not cause it, but just fired a warn in a different place due to adding the new warn call).
- For the root issue for what is causing the command timeouts, did you check the ceph OSD logs (normally in /var/log/ceph) like I mentioned in the previous comment? See the section "OLD REQUESTS OR SLOW REQUESTS":
https://docs.ceph.com/docs/master/rados/troubleshooting/troubleshooting-osd/
- Can you also confirm that on the current setup you are not seeing errors/overruns/drops in the ifconfig output for the interfaces you are using for ceph or vmware?
from ceph-iscsi.
I'm thinking that I have found the cause and wanted to wait till I'm sure
I think its due to low ram available on OSD hosts that causing this behavior
I have checked logs on OSD nodes and saw random slow-ops on disks furthermore checked the ram usage and saw when data is being written/read ram usage goes up and stops at a certain margin
so my monitoring station didn't warn me of it but I think bluestore do did not have enough ram to operate and disks show slow ops I don't have enough rams now so I'm thinking of adding new SSD for swap to check te behavior
