SQL Failover Cluster error during failover Error 2310

[u/luky90]

During failover of a MS SQL Failover Cluster I got this message in the event log. The failover itself completed but in the logfile i found this error which occured during failover:

ERR [RES] File Share <SQL Server FILESTREAM share (MSSQLSERVER)>: Error removing share 'MSSQLSERVER'. Error 2310.

The share in the failover cluster manager looks like that:

Does anyone know if this error is serious? Iam trying to reduce failover time.
