The error message was introduced in Resilio Active Everywhere Platform v4.0.0
Resilio Agent relies on a file system notification about new or updated files in the job folder and start syncing the changes as soon as possible.
This error indicates that one or more notifications were lost and respective file changes will be detected only on a next periodic rescan.
When error message appears
The error message appears if the storage does support file system notifications, but for a reason the Agent stopped receiving them:
- some notification were skipped (not not sent to the Agent) on large dataset update, for example, over 10,000 entries at a time;
- the job folder is a mix of mounted file systems, not all of which support FS notifications.
- Agent ran out of notify watchers.
- FS notifications are know to stop working sometimes for SMB shared on an OSX device.
When error message does not appear
It does not appear for the storages where the system notifications are not even supposed to work. For example, cloud storages, NFS or SMB2 mounted shares, etc.
How to workaround the error
- Acknowledge that file updates won't be detected by the agent instantly and likely will be picked up within periodicy rescan interval (24 hours by default)
- The fastest way to fix it is to launch manual rescan of the job folder on this Agent
- If this is expected - you can ignore the error
- To ensure agent detects changes faster - you can decrease periodic rescan interval. Please also note that it will require more disk resources
How to address the root cause of the error
- If it is related to lack of inotify watchers - follow this guide
- If access to your data is provided by a storage system like Netapp, Avid Nexis, etc. - please review your appliance settings for possible reasons of non-sending or losing filesystem notifications
- If your data is stored on Azure Files connected over SMB - it is worth checking:
- for other errors and their reasons
- if Azure is throttling your operations and update our plan or figure out which component is overusing the storage
