Longhorn in my Harvester has been working perfectly for a while. This morning I noticed that one of my VMs has stopped. I looked in the Longhorn UI and I see that the root disk volume is not happy. Whenever that volume is mounted it goes into an "Attaching" -> "Detaching" loop. How can I work out what happened? And how I can get that that partition back into a healthy mode?

Can you check the longhorn-manager log to see any related error?

The logs don't go back far enough to see what caused the issue to start. But there's loads of this going on - hundreds of lines per second.

Is the volume still at attach-detach loop? If yes, you can provide us the support bundle? Then, we can try to figure out the root cause.

Yes, still in an attach-detach loop. To recap: the volume was the root disk of a Harvester VM. The VM was running. Overnight, I'm assuming, something happened to the volume and the VM went into a stopping-starting loop. Two days prior I had rebuilt two of the nodes in the 3 node cluster - one after the other. Each time I waited for all of the volumes to be completely replicated to the newly rebuilt node before moving onto the next. I was happy that all volumes were working as expected - and the VM this volume was attach to was functioning correctly. Attached...

Thank you. Checking
From the support bundle, the volume 
pvc-3b137621-8434-456b-8f08-410ade838d8b
should have 3 replicas, but somehow there is only one replica 
pvc-3b137621-8434-456b-8f08-410ade838d8b-r-3e66e8d4
for this volume. However, the snapshot disk file’s metadata is missing, so the volume can’t be started and traps into the attach-detach loop.

Yeah, the snapshot disk `volume-snap-0b1e6133-4c31-4b2d-a15d-3742e757fa76.img`’s metadata is missing. Some questions need your help. I’m thinking how to fix it manually. 1. Did you take the snapshot of the volume manually? 2. Can you show the content of 
volume-head-006.img.meta
, 
volume-snap-b5d617df-075c-4850-a495-7818238ae609.img.meta

The 
volume.meta
shows this replica is at 
rebuilding
state, so I’m not quite sure if the replica is corrupted or not. However, we can try the following steps and see if the volume can be rescued. Before doing the steps, highly suggest backing up the replica directory (including all files). Steps: 1. Scale down the workload using the volume, then the volume should be detached. 2. Update 
volume.meta
manually ◦ Set 
Rebuilding
to 
false
3. Update 
volume-head-006.img.meta
manually ◦ Set 
Name
to 
volume-head-006.img
4. Scale up the workload --- As for the root cause of the issue, we need to further investigate, because the log messages are missing and not enough for analysis.

1. Scale down the workload using the volume, then the volume should be detached.
I believe the workload is scaled down. The Harvester VM is stopped. I did attempt to use Longhorn UI's "Attach" option to attach the volume to the node - but I see no way to detach the volume in the Longhorn UI. Is there a Longhorn kubernetes object I can manipulate to detach?
As for the root cause of the issue, we need to further investigate, because the log messages are missing and not enough for analysis.
To be honest, I'm quite worried that a Harvester VM could lose at least two replicas (from the nodes harvester001 and harvester003) and leave this replica in this "inconsistent" state. My fastest remediation would have been to toss this VM (it's "only" a kubernetes node, so it wouldn't take long to rebuild it). I hope that investigating the issue would help to fix an issue.

Oh, wait. Let me update the steps. The steps forgot to update 
volume-snap-b5d617df-075c-4850-a495-7818238ae609.img.meta
. Just to make sure if the workaround is feasible in your case 1. Scale down the workload using the volume, then the volume should be detached. (can skip if the workload is down) 2. Update 
volume.meta
manually ◦ Set 
Rebuilding
to 
false
3. Update 
volume-head-006.img.meta
manually ◦ Set 
Name
to 
volume-head-006.img
◦ Set 
Parent
to 
volume-snap-b5d617df-075c-4850-a495-7818238ae609.img
4. Update 
volume-snap-b5d617df-075c-4850-a495-7818238ae609.img.meta
manually ◦ Set 
Name
to 
volume-snap-b5d617df-075c-4850-a495-7818238ae609.img
 ◦ Set 
Parent
to 
""
5. Scale up the workload (can skip if the workload is down) The 2-4 steps are to fix the disk chain 
volume-head-006.img
-> 
volume-snap-b5d617df-075c-4850-a495-7818238ae609.img
.
To be honest, I’m quite worried that a Harvester VM could lose at least two replicas (from the nodes harvester001 and harvester003) and leave this replica in this “inconsistent” state.
You are right. Typically, Once the three replicas encounter errors, LH should auto salvage one of the replicas and rebuild the remaining two replicas. But somehow, the disk files/metadata files of the replica in your volume are messy. I guess there is a race condition when LH was doing replica rebuilding and snapshotting simultaneously. Do you mind opening a ticket in longhorn/longhorn with the support bundle? Then, we can continue investigating the issue and see if others have any idea. Many thanks.

I also noticed that there are a lot of orphan volumes on two of the nodes in the cluster too - I think I need to see if there is any correlation on the times for the orphans to the approximate time of the failure of the this specific volume.

The copy I made as a backup before thinking about following your procedure is:

mdsh-copy_2022-12-02_pvc-3b137621-8434-456b-8f08-410ade838d8b-0ade9458
I believe I made all of those alterations and the volume is still in the attach-detach loop.

I have tried to start the VM in Harvester which uses this volume, and the VM just hangs in the "starting" phase. All three nodes in this cluster have been restarted, before I made the changes above, because of the Harvester update to v1.1.1 - which left Longhorn at v1.3.2.
Curiously, over night the attach-detach loop has stopped - although the contents of the files has not changed.

There is still only one replica.
I tried starting the VM in Harvester and the volume went into the attach-detach loop until I stopped the VM. This is the first few seconds of logs from the Instance manager - Slack won't allow me to paste more...

From the latest support bundle, the volume was attached and then detached repeatedly. Not sure if the volume is corrupted and the application (I mean harvester) found the error and detach it. You may need to rebuild the node .
For the root cause of the messy disk metadata files, I will continue the investigation.

Thank you. I only kept the volume (and it's VM) around in case you needed to study it further.
