Hi

I have an issue on my infrastructure

I have a proxmox server cluster (with 3 nodes and CEPH)
I have a physical server with PBS installed

When I try from Proxmox Server UI to download simple file from a backup no problem
But if I try to download a folder with many files (~50Gb), the file downlaod and finishe correctly but zip seems corrupted (and same with .tar.zst extension)


Informations:

All nodes of Proxmox sevrer are in
Virtual Environment 8.4.14

PBS is on Backup Server 3.4.8

Thank all for helping me
 
corrupted how? is it truncated, does it contain bogus data, ..?
 
When I try to open on Arc (Zip fil manager on Debian) I have this error:


"Possibly truncated or corrupted zip archive"

And nothing appear on the archive
 
does the file have a reasonable size or is it actually empty?
 
could you do "stat /path/to/file" and post the output here? thanks
 
Code: 
stat 2023.tar.zst                                                                                                                                                                                                                                                                                              [14:19:35]

okay, so it's not a 32G file size limit ;) is this a VM or a container backup? are you using the PVE or the PBS UI to download?
 
It's from a VM backup (Nextcloud) and trying to download entire folder from Nextcloud user

I'm using PVE UI to download
 
thanks!

if you retry (please ensure there are no other file restore tasks running in parallel), could you post the /var/log/proxmox-backup/file-restore/qemu.log file corresponding to your file restore?
 
Hum... very strange during backup procedure and ZIP download, no log in the path you have put

Las modification of this file is
Code: 
-rw-r--r-- 1 root root 6.6K Dec 14 21:03 /var/log/proxmox-backup/file-restore/qemu.log
With:

Code: 
watchdog expired, shutting down

you need to look on the right node, in case this is a cluster.
 
you need to look on the node that your PVE UI talks to/is connected to
