Workaround found here https://xcp-ng.org/forum/post/94626

Seems like turning "Use NDB to transfer disk if available" switch ON and save backup job,
then turn the switch OFF and save backup job again, will fix the issue.

Thanks to @RobWhalley and have a nice day everyone.

@RobWhalley Thank you... Works for me as well, good job!

Have a great day everyone.

My XO VM Backups were working just fine till last update that I did last night.

From today the XO VM Delta Backup says "Started" but never "Successful" (it is never completed).

• I'm on XO (built from source) and trying to do Delta Backup of my XO VM to NFS share.
• I don't see any recently unfinished Tasks.
• Other VM backups are "Successful".
• XO config and Pool Metadata are "Successful".
• NFS Remote on latest version of TrueNAS scale Test Passed OK.
• Local Storage (where XO VM resides), XCP-ng host and NFS share all have plenty of free storage space available.
• I did already restart of everything, TrueNAS, XCP-ng host and XO VM it self.

Nothing helped so far.

I'm on latest XO version from 30/06/2025 - commit no. 48bf9c9

Any idea where to start troubleshooting steps? Should I try to rollback previous snapshot that is still available?

Thank you in advance for your kind help, any information appreciated.

Have a great day, regards,

Vladislav

@gduperrey said in XCP-ng Tools Storage contains VDIs I’m unable to Destroy:

It seems that it is possible to clean old isos manually, via the command line, as explained in this forum post: https://xcp-ng.org/forum/post/15703

Wau!!! That actually works like charm!

Thank you sooooo much!

@gduperrey Hi and thanks for reply.

No I don't have really a space problem, and I understand that they do not take any place (if it seems like they are pointers to nowhere), because I cant find them on the disk and probably thats why I'm also getting an error when trying to delete them, because I'm probably trying to delete something that doesn't reference any real file.

It just only bothers my OSD... I don't like to see something on my system which doesn't make sense to be there.

@olivierlambert Thanx for quick reply, and...

yes, that's what I've tried, couple times already.

I even tried to disconnect the XCP-ng Tools storage from the host and reconnect again... unfortunately these mysterious files are still displayed, but seems they are not actually present on filesystem.

Hello guys,

on my XCP-ng Storage I have apart of ‘guest-tools.iso’ (that is normal)
also couple of ‘Old version of guest-tools.iso’ (viz. screenshot)

If try to destroy these extra “old versions” it fails with an error:

SR_OPERATION_NOT_SUPPORTED(OpaqueRef:51da4fff-c220-478f-843a-0e80ea9514d0)

Log related to this operation attached here:
2024-10-15T08_01_06.363Z - XO.txt

Storage seems to be connected to local path /opt/xensource/packages/iso

But ls shows only one file with latest guest tools iso:

[20:23 xcp-ng ~]# ls -lha /opt/xensource/packages/iso/
total 17M
drwxr-xr-x 2 root root 4.0K Oct 10 22:36 .
drwxr-xr-x 4 root root 4.0K Oct 10 22:36 ..
-rw-r--r-- 1 root root  17M Sep 20 15:06 guest-tools-8.3-12.xcpng8.3.iso

The other files that are shown on the picture above, surprisingly, are not there.

Any idea how to get a rid of these? Can anyone give an advice?

Thank you and have nice day everyone.
