Challenge
The patching of the Veeam Recovery Media fails with the error:
ISO: FATAL ERROR:write_file: failed to create file /tmp/veeam/livecd-..., because Too many open files
Cause
Veeam Agent reaches the limit of concurrently opened files during the ISO image unpacking that is performed by means of the unsquashfs utility.
Solution
Increase the limit of concurrently opened files for the Veeam Agent service. To do this, perform the following operations:
- Open the service file for editing:
sudo systemctl edit --full veeamservice.service- Set the following values:
[Service]
LimitNOFILE=524288
LimitNOFILESoft=524288- Save changes:
sudo systemctl daemon-reload && sudo systemctl restart veeamservice.serviceIf this KB article did not resolve your issue or you need further assistance with Veeam software, please create a Veeam Support Case.
