asds cannot be claimed after a node is removed and then added in #2214

Open yongshengma opened 5 years ago

yongshengma commented 5 years ago

Hi,

I got an issue after a node was removed from cluster. This ticket's title is not accurate enough at this moment.

Lets's say A, B and C are three nodes of the cluster. They were installed and setup in the order of A, B and C. I did the following:

  1. removed node A when it's offline
  2. re-installed OS on A
  3. configured network with the same IP as before removed
  4. installed ovs
  5. ovs setup
  6. assigned roles
  7. added this new ASD node into backend
  8. initialized ASDs
  9. claimed

Now claiming icon keeps on spinning and can't end.

This issue also happened when I added fourth node into cluster. So I would conclude that all ASDs' claiming will get stuck if more nodes join in. However there's no this issue if no remove node operation.

BTW, ovs setup on the fourth node has no problem. It is setup as an extra node without master role. All ovs services are running.

yongshengma commented 5 years ago

my all nodes are physical servers.

yongshengma commented 5 years ago

I find there's no alba maintenance running on this node.

Claiming ASDs still doesn't work after I paste alba maintenance cmd line according to JeffreyDevloo's suggestion in #1703 .

JeffreyDevloo commented 5 years ago

Do you have logging from the ovs-workers? I'd like to follow the trail on this one. The task name is alba.add_units.

Best regards

Jeffrey Devloo

yongshengma commented 5 years ago

Attached log from journalctl -u ovs-workers. I clicked claim again just now, so the newest 10 minutes should be your interest. i didn't see alba.add_units in it. workers.zip

I reinstalled and set up a cluster and replicated this issue. I removed an offline node and reinstalled OS+OVS.

I noticed the following on newly added node:

JeffreyDevloo commented 5 years ago

Hi yongshengma

Try to grep for add_units on all nodes within the cluster. The distributed nature of the ovs-workers might execute a task on a host different from where you sent the API call to.

The 'missing' services look to be volumedriver and abm/nsm service. Volumedriver related services are only added once you extend the vpool to the new host. The ovsdb arakoon is not deployed on the DB role. It resides under /opt/OpenvStorage/db instead. ABM and NSM arakoons will be added again after sometime (its scheduled to check every 30 minutes by default). You can manually ensure the checkup using:

from ovs.lib.alba import AlbaController
AlbaController.scheduled_alba_arakoon_checkup()

Best regards

Yes, I find related info on another node as what you said. grep add_units /var/log/syslog

I find it's not always true that asds cannot be claimed after a node is removed, reinstalled and added in. Most of time they can be claimed and then everything works. But sometimes it doesn't work and asds cannot be claimed even on a new node which means IP and hostname are totally new.

Hi JeffreyDevloo , I just noticed that the code I'm using has difference. The URL for claiming is the following on my node: /api/alba/backends/7dcb2c30-3cb5-4cd9-85c4-92f27e4468b8/add_osds/?timestamp=1548300223638 which is add_osds instead of add_units.

I think you were asking to search albabackends.add_units , but I'm sure I got the same issue In original F version.

toolslive commented 5 years ago

there are some things you can check: 1) are the ASDs you want to claim present in the output of the list-available-osds command ? $> alba list-available-osds --config <abm-url> 2) are the ASDS up and running ? (the connection refused error message hints that this is not the case) 3) can you claim the asds via the command line ?

yongshengma commented 5 years ago

Hi toolslive, Any clue about abm-url ? An example would be nice.

toolslive commented 5 years ago

it's an arakoon with the role of abm, so

$> pgrep -a arakoon | grep abm
...
5992 /usr/bin/arakoon  --node wZ4GAcmR2MZl5x7S -config arakoon://config/ovs/arakoon/ny1-hddbackend01-abm/config?ini=%2Fmnt%2Fssd1%2Farakoon%2Fexternal_arakoon_cacc.ini -autofix -start
....

so the abm's url for that alba is arakoon://config/ovs/arakoon/ny1-hddbackend01-abm/config?ini=%2Fmnt%2Fssd1%2Farakoon%2Fexternal_arakoon_cacc.ini it's needed when you want to do things with that backend (add namespaces, delete namespaces, add osds, claim osds, purge osds, ....)

Mind: Your environment might have multiple backends and not all nodes run an arakoon for a backend's abm.

yongshengma commented 5 years ago

Nice, very nice! I have only one backend so far.

192.168.0.49 is the target node I'm struggling on ASD claiming. There should be 4 hard drives and so asds.

toolslive commented 5 years ago

you can add it via the cli alba add-osd --help (to add an asd, you will need its host and port , the abm-url for the backend) After you've add it, you can list it with `list-available-osds', and you can claim it (via the cli).

toolslive commented 5 years ago

normally, ASDs are discovered by alba components (maintenance, proxies) via UDP multicast. But this multicast does not always work because of network (configuration) issues.

yongshengma commented 5 years ago

Just cannot play around add-osd.

I believe something missing. For example, how to assign OSD id ?

Cool ! Appreciate!

Hi Yongshengma

The underlying commands is what the Framework also invokes. I'm still interested why the claiming was unsuccessful in the first place. If you'd ever find yourself back in the situation, please provide me the worker logging and I'll look into it.

Best regards

yongshengma commented 5 years ago

Hi JeffreyDevloo

Sure. No problem.

The add-osd didn't provide an option to specify an osd id, did it? Does it look for only one available each time?

toolslive commented 5 years ago

there are 2 id's in this context. osd_id : this is the number the abm gives the osd when it's added (it just increases) long_id : this is the world wide unique identifier of the osd. The osd creates this when launched for the first time (and it will communicate this when you connect to it)

The previous claiming issue still exists even if I powered off network switch and powered it on. I just used cli to claim osds one by one.

However I got a new issue afterwards. When I extended the vpool to this node, the action failed and gave error:

Jan 25 11:29:17 NODE-3 celery: 2019-01-25 11:29:1707400 +0800 - NODE-3 - 42057/140345664415552 - celery/log.py - log - 109 - ERROR - Task ovs.storagerouter.add_vpool[dc313fcc-49cf-4281-9c1d-3e33d3df7993] raised unexpected: ConnectionError(MaxRetryError('None: Max retries exceeded with url: /api/oauth2/token/ (Caused by None)',),) stuck again. NODE-3 is the node I'm accessing webapi. NODE-9 is the target node for vpool to extend to.

Two more info before :

It tries to connect host='192.168.0.41', but this host has been removed and the NEW node is not this IP any more. It looks like the old endpoint is still hiding somewhere.

Hi @JeffreyDevloo

Attached logs are from F version. You will find 3 nodes' logs: 192.168.2.31, 192.168.2.32, 192.168.2.33. Cluster was set up in this order.

Steps I did:

Continue :

My workround

I accessed web page on 192.168.2.33 node, so the log of 192.168.2.33 contains the whole process that I did above.

So far this issue always occurs on the first installed node and it absolutely appears. Another place worth to say: 192.168.2.31 node has been removed, but vpool's detail page shows this vpool's connection is still 192.168.2.31:443. This info is wrong, isn't it ?

Hi @toolslive

What's the alba command for reverse operations? I mistakenly took away a hard drive running as an ASD and the data has been wiped out. This caused framework-alba-plugin UI hanging. I think I have to remove this ASD from backend. Should I use alba asd-delete first and then purge-osd? What does the key required by asd-delete look like?

Best regards, Yongsheng

toolslive commented 5 years ago

no. asd-delete allows you to delete a key value pair from an asd. This is NOT what you need. you just need to have maintenance running and call

alba purge-osd --long-id <long-id> --config <abm-config-url>

The <long-id> you need can be retrieved via alba list-osds ... After that call, the ASD will eventually be removed from the cluster.

It helps! Thanks!
