@Tackyone
You solution fixed it for me. Lost a few days of logs as well and i am on the latest commit of the XO community edition.

Theres some bug with syslog clear but your fix works great.

@olivierlambert

Nevermind. Second time the upgrade went smoothly.

HolySmokes.......XO Lites is niiiiiice.

Great job all around

@olivierlambert
Now that im back on 8.2 where i can look in the filesystem to review the logs?

@olivierlambert I can use the 8.3 ISO to reload 8.2 ?

System: Dell R620
XCP NG:8.2

Got in through idrac and attempted to upgrade to 8.3. After a few minutes i received the following error

I went ahead and rebooted the system as that was the only option but not i get to the grub menu.

Cany anyone provide any pointers as to how i can rescue this server?

@olivierlambert Im confident it will all come together in the future!

@Danp
You are correct. That was not intuitive or discoverable at all for me but I do stand corrected in my comments.

Thank you @Danp

@olivierlambert Not removed but made clear. A giant banner at the top of the page indicating that its a work in progress.
No where on the page do I see that its not available. If I missed it that's sort of my point then. There is nothing on the page to indicate that it isn't available but there are screen shots of how to configure. It doesn't make sense when reading.

If any feature is still being developed a helpful banner on the page would be helpful for the reader

As you can see nothing is really configurable here.

@Bastien-Nollet
I was just about to post an exact question until I decided to search.

Please update the documentation to make it clear its a work in progress. Between the screenshots showing where to look for the plans and the fact that its in the official documentation it's all very confusing.
Some indication to the reader OR just remove the section until its finished?

@florent Yes i have a support tunnel IP.
id: redacted but kept by our team

@Andrew
Thanks!
Watching that Issue now.

@olivierlambert Ive created a support tunnel and sent you a DM of the id if you want to check out.

@olivierlambert
Thanks for the temp trial.

The issue is still present on an updated XOA.
I add my Remote. Go to back up > file restore. I see my deltas there. I attempted to file restore and was greeted with the same message as the self-compiled version

@olivierlambert I did notice the difference initially but XOA back up jobs are not available under 'XOA' so that's why i brought up XO.

@manilx Thank you for the link. The fix in that thread worked.
tldr. Problem with the ronivay self compiled code. Reverting to old commits fixed issue. Will be watching for a fix.

@StormMaster
I dont see a PR or even an issue posted on the github. I can add one to the board for ronivay unless someones working on it.

Got a strange one here. I have a few back up jobs that all run successfully except one.
When its time to do the health check and restore it just hangs. I restart the toolstack as there is no way to stop a back up job and i get the below error
This is the only back up job that wont complete. The job is configured the same way as the others.

There has been no progress for over 5 minutes. It will stay in this stuck state until i restart the toolstack on the host.

@olivierlambert

Hi Oliver. I am on the latest XO as i shown in the photo above.

Greetings,
Ive searched the forums here but it seems there hasn't been conclusive evidence of XO and file restore from backup issues. Im wondering if anything has changed since 2021 which is the post I've found regarding this issue.

So I've noticed that if i build virtual machines using LVMs, file restore is not possible. Is this a known issue? Is there a work around?
These are delta backups.

I always receive the following error from any machine with LVM file system.

When i select a VM without a filesystem built using LVM file restores are possible.

I am on a built from source XO.

The output of the failure is below.
Background: attempting to run delta back ups results in failure. Full backups do work to the smb share. I get a cryptic error "NO_HOSTS_AVAILABLE() butthat doesnt make any sense and not very verbose.
