@TheiLLeniumStudios Better explanations, to reintroduce a LINSTOR SR, you can use these commands with you own parameters:
Generate a new SR UUID.

Now it doesn't show up and when I tried your suggestion of running xe sr-introduce, it just creates an "Unknown" SR and doesn't link it to the previous one. Running xe sr-create also doesn't help since that errors out with LINSTOR SR creation error [opterr=LINSTOR SR must be unique in a pool]
If you have this error, the LINSTOR PBDs still exist. Are you sure you forgot the previous SR?
So, with XOSTOR created and making the Pool HA with that SR, whenever I created a new VM in that SR and not choose any affinity host, it takes atleast 10-15 minutes to run a migrate task which shouldn't be necessary because XOSTOR is shared right?
Regarding the migration, it's correct if the SR is created with shared=true, and if you migrate the VM between two hosts with the same SR used, the migration should be short.
After repairing your SR, you can do a VM migration and send me the logs of the machines if you want, I can take a look.
-
@AudleyElwine If you forgot your SR, you can follow the instructions I gave in the previous message. Otherwise, check if the PBDs are correctly plugged to the SR, it's probably not the case.
-
@ronan-a I did not forget the SR so yeah it is the PBDs.
I tried to plug them back withxe pbd-plug uuid=...taking the uuid from the
xe pbd-list sr-uuid=xostor-uuidI was able to plug three hosts, however the last forth host says the following.
Error code: SR_BACKEND_FAILURE_1200 Error parameters: , Cannot update volume uuid 36a23780-2025-4f3f-bade-03c410e63368 to 45537c14-0125-4f6c-a1ad-476552888087: this last one is not empty,What do you think I should do to make the forth host pbd connect to delete the SR correctly?
-
@ronan-a I just tried to reintroduce the SR and I got no errors while running xe pdb-create but it still shows up as a -1 Size SR. I think I might have corrupted the metadata as checking lvs, vgs and pvs throw errors:

@AudleyElwine said in XOSTOR hyperconvergence preview:
Ho! Sounds like a bug fixed in the latest beta... In this case, ensure there is no VM running, and download this script:
wget https://gist.githubusercontent.com/Wescoeur/3b5c399b15c4d700b4906f12b51e2591/raw/452acd9ebcd52c62020e796302c681590b37cd3f/gistfile1.txt -O linstor-kv-tool && chmod +x linstor-kv-toolFind where is the running linstor-controller, so execute this command on each host:
[11:13 r620-s1 ~]# mountpoint /var/lib/linstor /var/lib/linstor is a mountpointIf it's a mounpoint, you found it. Now, you must execute the script using the local IP of this host, for example:
./linstor-kv-tool --dump-volumes -u 172.16.210.16 -g xcp-sr-linstor_group_thin_deviceThe group to use is equal to:
<VG_name>_<LV_thin_name>. Or just<VG_name>if you don't use thin provisioning.
Note: there was a bug in the previous beta, you must double thexcp-sr-prefix. (Example:xcp-sr-xcp-sr-linstor_group_thin_device)So if you have an output using this script with many entries, you can run
--remove-all-volumesinstead of--dump-volumes. This command should remove the properties in the LINSTOR KV-store. After that you can dump a new time to verify.Now, you can execute a scan on the SR. After that, it's necessary to remove all resource definitions using the
linstorbinary.Get the list using:
linstor --controllers=<CONTROLLER_IP> resource-definition list āāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāā® ā ResourceName ā Port ā ResourceGroup ā State ā āāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāā” ā xcp-persistent-database ā 7000 ā xcp-sr-linstor_group_thin_device ā ok ā ā xcp-volume-0db304a1-89a2-45df-a39d-7c5c39a87c5f ā 7006 ā xcp-sr-linstor_group_thin_device ā ok ā ā xcp-volume-6289f306-ab2b-4388-a5a2-a20ba18698f8 ā 7005 ā xcp-sr-linstor_group_thin_device ā ok ā ā xcp-volume-73b9a396-c67f-48b3-8774-f60f1c2af598 ā 7001 ā xcp-sr-linstor_group_thin_device ā ok ā ā xcp-volume-a46393ef-428d-4af8-9c0e-30b0108bd21a ā 7003 ā xcp-sr-linstor_group_thin_device ā ok ā ā xcp-volume-b83db8cf-ea3b-47aa-ad77-89b5cd9a1853 ā 7002 ā xcp-sr-linstor_group_thin_device ā ok ā ā°āāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāāÆThen execute
linstor resource-definition delete <VOLUME>on each volume. But don't do that on thexcp-persistent-database, only onxcp-volume-XXX!Normally after all these steps, you can destroy the SR properly! I think I will write an automated version for later, like
linstor-emergency-destroy. -
@TheiLLeniumStudios Can you plug the PBDs? If there is no issue here, you can follow the same steps as AudleyElwine.

@AudleyElwine said in XOSTOR hyperconvergence preview:
Really strange... Maybe there is a lock or another issue with LINSTOR. In the worst case you can retry after a reboot of all hosts. If it's always stuck I can take a look using a support tunnel, I'm not sure to understand why you have this error. -
@ronan-a I started updating xcp-ng so it can both restart and update on my four nodes (eva, phoebe, mike, ozly).
The nodes were updated with the rolling method, and all three node updated fine, except the forth (mike) (different that the ones that refuses to connect the PBD(eva)) since it is task was stuck at 0.000 progress for 3 hours, so i restarted the toolstack for it(mike) but it didnt do anything, so i restarted the master(eva) node stack. Then when I went to manually update it from XOA, it gives me this error.-1(global name 'commmand' is not defined, , Traceback (most recent call last): File "/etc/xapi.d/plugins/xcpngutils/__init__.py", line 101, in wrapper return func(*args, **kwds) File "/etc/xapi.d/plugins/updater.py", line 96, in decorator return func(*args, **kwargs) File "/etc/xapi.d/plugins/updater.py", line 157, in update raise error NameError: global name 'commmand' is not defined )The good news is, the linstor controller have moved to a different node(phoebe) from the old one(mike) and I was able to delete all volumes in the
linstor --controllers=... resource-definition listexcept for the database, yet the PBD(eva) could not be connected. And the XOA still shows me a lot of disk, and when I scan it I get this errorSR_HAS_NO_PBDS.So now mike server cant update, and eva server cant connect its PBDs while all the other servers are connected. Note eva was the server that I started my linstor installation on.
Do you have any thoughts on what I can do to fix this without reinstalling xcp-ng on mike?

Figured out the issue, when I tried to update it from the cli instead. the
/var/logpartition was full due to/var/log/linstor-controllerhaving something like 3.5G+ data (90% of the/var/logvolume). maybe it is due to the past errors it accumulated. I deleted these logs and mike updated normally.Now regarding plugging the PBD to eva (the one host that is not connecting to it). it says the following error.
Error code: SR_BACKEND_FAILURE_202 Error parameters: , General backend error [opterr=Base copy 36a23780-2025-4f3f-bade-03c410e63368 not present, but no original 45537c14-0125-4f6c-a1ad-476552888087 found],this is what linstor resource-definition is showing

So yeah happy ending. Will try the next beta version. Thank you @ronan-a for your work.

@ronan-a I tried following the guide that you posted to remove the linstor volumes manually but the resource-definition list command already showed a bunch of resources in a "DELETING" state.

@TheiLLeniumStudios In this case, if DRBD is completely stuck, you can reboot your hosts. There is probably a lock or processes that have a lock on them.
-
@AudleyElwine Thank you for your feedbacks, I will update the script to handle the journal cases.
-
@ronan-a 2 of the nodes broke after restarting. I just kept getting the blinking cursor at the top left of the screen for hours. I'm going to have to reprovision all the nodes again sadly
-
Hey @ronan-a ,
What should I do to lower the chance of something in the past installation of xostor to affect my new installation?
lsblkis still showing the linstor volumes,vgsis also showinglinstor_group.
Will awipefs -afbe enough? Or is the "Destroying SR" button in XOA is enough? -
@AudleyElwine The PVs/VGs are kept after a
SR.destroycall but it's totally safe to reuse them for a new installation. The content of/var/lib/linstoris not removed after a destroy call, but it's normally not used because the linstor database is shared between hosts using a DRBD volume and mounted in this directory by the running controller. So you don't have manual steps to execute here.Of course if you want to reuse your disks for another thing,
wipefsis nice for that. -
@TheiLLeniumStudios There are always a solution to repair nodes, what's the output of
linstor --controllers=<HOST_IPS> node list?(Use a comma separated values for HOST_IPS.)
