You shouldn't have the testing repo enabled to start. The version of the snapraid plugin in the testing repo is a big change (multi arrays and split parity).
Did you clear your browser cache? Are you executing the scrub from the Array tab?
Tried clear browser cache, but the problem keeps occurring.
Yes , i have testing repo enabled. But the version of snapraid plugin seems still 6.2.1 after disabling testing repo.
If I uninstall and reinstall the plugin, do I lost the settings?
Thank you.
