A local backup task failed. How do I resolve this?
ZSvirt was open-sourced from the ZStack ZSphere commercial project and has since developed independently. Some code, configuration, and documentation still retain historical ZStack/ZSphere names (such as environment variables, configuration items, dependencies, paths, and commands). These names are for compatibility only and do not affect the normal use of ZSvirt.
Cause
The number of open files for the process exceeded the limit.
Solution
-
Log in to the local backup server and run the following command to check the connection count:
[root@localhost ~]# lsof -p `pgrep zstore`|wc -lThe max open files limit is 4096. If the returned connection count exceeds 4096, the process has exceeded its open file limit.
-
Run the following command to restart the zstore service and release connections:
[root@localhost ~]# systemctl restart zstack-imagestorebackupstorage.service
