after downgrading xcp host from trail 90% of my vms are not booting..
-
pretty much the same issue noted here
Re: FAILED_TO_START_EMULATOR restarted Xen stack tools and rebooted the hosthowever my systems where always in bios mode.
the VMs that use local storage boots fine any vm on the other 2 locak SR's do notall linux vms, all had tools installed...
error is
xencenter

It would likely help if you provided some additional details, such as --
- You mentioned a trial. Did you mean the 8.3 beta?
- What are the exact steps you performed to downgrade your host?
- Are you now running v8.2.1? Fully patched?
- Is this the pool master?
- You mentioned "other 2 local SRs". Can you tell us more about them?
Does restarting the toolstack fix the issue, even temporarily?

@anp
i did not know there was more than 1 trial .
yall have " please try for free listed" everywhere in XOA
it only last 15 days then downgrades everything.. it all worked till i rebooted the vms -
no , restart toolstack or the server does not work.
there is only 1 host
2 Sr's are local.. 1 is SAS drives raid 0 , and the other is SSD SAS raid 0the only one that works is raid 1 local drive. i also see it has a cache read options the others do not have
steps i took to downgrade was what it asked me in the xoa updaters page after the trial ended -

@yford The thread title mentioned XCP host and trial, so I thought that maybe you were referring to the XCP-ng v8.3 beta that is currently available for testing. That's why I asked for more information so that we can be sure how to best assist you.
Downgrading your XOA from a Premium trial to XOA Free wouldn't cause the issues that you are describing, so something else must be happening here. I can see the error message in your screenshot, but otherwise it's not really helpful.
I haven't used the Windows client in forever, so I can't tell if the toolstack restart was successful or failed. Can you try restarting the toolstack using XOA? Also, can you show us a screenshot of the host's Storage tab in XOA?

ok yeah i would of said upgrade.. but yes i try to keep it simple so i dont break anything and loose months of work lol
i did the trial to see if i can gain performace, as my last topid was performance issues..
with kubernetes running in vms..then i also opened it up with longhorn pvc provider , in which i learned there seems to be a lack of I/o in these vms
https://github.com/longhorn/longhorn/issues/8303
i xoa locked me aout an wouldnt do anything till i downgrad so i did as it asked.. i do not know what i douwngrated to or what it did behind the scenes..
systems was working for a while but i seen vms started acting up .. so natuarally rebooting them has always fixed it.. not this time.. only vms on /dev/sda are working now

Your trial expired, so it forced you to revert to XOA Free and no longer you had access to features such as backups but you are still able to manage your VMs.

It sounds like you have storage that isn't mounting, which wouldn't have anything to do with XOA and wouldn't have been caused by downgrading from the Premium trial.

Thanks Danp , it is curtainly a huge coincidence then .. my i/o issues had me rebooting constantly for weeks.. soon as i downgrade i can not reboot anymore.. Anyways how can i force it being mounted
i do see a error about the vdi failed when scaning the repo..
please do not tell me i need to delete all an recreate them

@yford
also when the trial expires the whole panel is useless till you downgrade.. everylink you click takes you to the downgrade.. u can not use xoa till the downgrade is complete -
@yford How about https://forums.lawrencesystems.com/t/how-to-build-xen-orchestra-from-sources-2024/19913
Takes you 15min

Yes, that is clearly by design.
my i/o issues had me rebooting constantly for weeks.. soon as i downgrade i can not reboot anymore..
Sounds like you were having storage problems before the XOA downgrade.
i do see a error about the vdi failed when scaning the repo..
please do not tell me i need to delete all an recreate themYou could check
/var/log/SMlogto see if it provides further details related to this VDI. -
thats not correct . only in these vm's there is issues, test proves fine in the host or any other os performance issues and errors is only in the vm's themselves
also in the host it shows as there mounted and all drives test fine and have great speed an performance in the host

here is the complete logs for smlog

I haven't checked your pastebin yet, but those definitely appear to be storage issues to me based on the logs shown in your screen shots. You should post the output of
pvdisplay,lvdisplay, andvgdisplayfor the affected storage. -
reboote the server and it did not come up lol dude these drives are good, hardware is good.. something to do with this hypervisor.. think i may need to reinstall the os tommorow..
if there is a repair option in this iso i will try it..
most is kubernetes so deploying is easy .. but my git was not updated in weeks so im scared i will loose data from one of the vms. i wish i could mount it somehow externally is that possible?
ill run your commands tommorow though

@yford said in after downgrading xcp host from trail 90% of my vms are not booting..:
2 Sr's are local.. 1 is SAS drives raid 0 , and the other is SSD SAS raid 0
the only one that works is raid 1 local drive
I'm confused by the above. Are there 2 local SRs or 3? How were these created?
Which SRs are working correctly and which SRs are giving you problems?

I said that you appear to have a storage problem, which doesn't necessarily imply a hardware problem.
i wish i could mount it somehow externally is that possible?
I imagine so, but it depends on many factors that are unknown at this time.

just want to say after reinstalling all and recreating the all repositories i do have any disk errors or IO issues
