Unable to parse free thin sizes error on Satellite

[containerman17]

Hi guys! I am using Linstor with Piraeus. I have an error Unable to parse free thin sizes at /v1/nodes/xxx-eu1/storage-pools.

Here is log from node:

I am using imnage quay.io/piraeusdatastore/piraeus-server:v1.1.2
Some info from node startup:

LINSTOR, Module Satellite
Version:            1.1.2 (6fa27183eed583088e07b757cdef61ba13a14854)
Build time:         2019-09-16T07:13:07+00:00
Java Version:       11
Java VM:            Debian, Version 11.0.4+11-post-Debian-1deb10u1
Operating system:   Linux, Version 4.15.0-65-generic
Environment:        amd64, 1 processors, 15547 MiB memory reserved for allocations

So I found this error mentioned in satellite/src/main/java/com/linbit/linstor/storage/utils/LvmUtils.java:234

And I found a command here:
satellite/src/main/java/com/linbit/linstor/storage/utils/LvmCommands.java:324

One the compute node I executed:

root@xxx-eu1 ~ # vgs -o lv_name,lv_size,data_percent --units b --separator ";" --noheadings --nosuffix
  hdd-pool;10000667770880;
  root;536870912000;
  nvme-pool;1510280790016;

Looks like data_percent is empty for some reason. What can I do with it? How can I fix it?

Compute node is bare-metal Ubuntu 18.04.3 LTS server with physical nvme and hdd disks.

Please also post error report # 5D962D62-E3A0D-000000, which contains details about when and where in the code the problem occurred.

[containerman17]

Hi! I didn’t find a way how to look into this report. Is it stored on host machine somewhere?

It happened right after node reboot
P.S. Confirmed. The error occurs only after reboot.

[containerman17]

Ok. So LVM 2.02.176 on Ubunbtu shows empty field data_percent . Temporary solution - to create a thin volume in every pool. More permanent one - change method getThinFreeSize so it will handle hdd-pool;10000667770880; as hdd-pool;10000667770880;0.00.

Hello

Thanks for the report as well as the research of the actual cause. Unfortunately I am still unable to reproduce this on my test system, even with rebooting the machine.

I am sure we could implement your suggested permanent fix, although I would add an additional safety check, something like "if data_percent is missing AND lvs does not show any volumes in that pool". However, I still would like to know what I am missing that prevents me from reproducing this issue.

• How did you create your thin pool?
• What does lvdisplay say when your vgs is missing the data_percent? Especially interesting is the Allocated pool data (or its absence)
• (This is just a wild guess, might be nothing at all) - can you please create a smaller thin pool? Something like 100G? And see if that issue still persists?
  The wild guess here is, that in my case the 0.00 is actually something like 0.000001, but I only test with very small thin pools. Your thin pool is about 10TB large, which might result due to rounding issues actually to 0.0. That could be the mysterious difference when you imagine a check like if (data_percent){ ... } inside the vgs / lvs code

Hi,

I faced this same issue, seems that there was a problem related to a missing package dependency (thin-provisioning-tools) in the system that prevent the system from mounting the thinpool device on boot. After installing the missing package I was able to mount the device and it's still there after reboot.

Thanks for the info!

As this sounds reasonable enough for me I will close this issue for now. Feel free to reopen if there are still open questions.

END OF ERROR REPORT.

I use XCP-ng (Centos) here, the equivalent package of thin-provisioning-tools is already installed. It's the device-mapper-persistent-data RPM.
After deleting the devices, the problem has disappeared, quite strange. It's the first time that I see this problem. 🤔

[ghernadi]

All I see from the ErrorReport is that Linstor got this line:

thin_device;246960619520;

Howevr, Linstor is actually expecting a 3rd column indicating a percentage of how much of the device is already in use. This information is required by Linstor in order to properly report those numbers back to the controller, thus to the user and plugins..

[danoh]

Hello,

I'm encountering the same issue on a fresh Debian 12 installation. The "percent" column is missing for all newly created thin volumes that haven't had any logical volumes created yet. Rebooting doesn't resolve the problem. In fact, whenever I create a new thin pool without any logical volumes, the lvm2 utilities don't display the "percent" column at all.

This issue can be addressed using the --reportformat json flag. In this case, the column is populated with zeros.

Installing the thin-provisioning-tools package doesn't seem to help in this specific scenario.
