Upgrade Proxmox 8 to 9: Migrate RRD metrics / Error: Can not open source RRD

[Angus.MacGyver]

Dear all,

I just upgraded my Proxmox VE 8 to 9; right after the upgrade pve8to9 --full tells me to manually run /usr/libexec/proxmox/proxmox-rrd-migration-tool --migrate .

Unfortunately I get this error:

root@pve202:~# /usr/libexec/proxmox/proxmox-rrd-migration-tool --migrate
Migrating RRD metrics data for nodes…
Node: 'pve202'
RRD create-migrated error: Cannot open source RRD /var/lib/rrdcached/db/pve2-node/pve202
Tried to migrated metrics of all nodes to new format - see output above for details.

What should / could I do next?

Best regards,

Hi!

Could you post the outputs of ls -l /var/lib/rrdcached/db and ls -l /var/lib/rrdcached/db/pve2-node?
