Test failover

Mount the share on Windows:

PS C:\Users\tux> net use z: \\SMBCLUSTER\SH1 /USER:[email protected] <password>

Create a test file with the following syntax:

fsutil file createnew "FilePath\FileName.FileType" FileSize

FileSize is designated in bytes:

1 MB = 1048576 bytes
100 MB = 104857600 bytes
1 GB = 1073741824 bytes
10 GB = 10737418240 bytes
100 GB =107374182400 bytes
1 TB = 1099511627776 bytes
10 TB =10995116277760 bytes Copy the test file from local client volume to SMB share. While copy is ongoing, place cluster services on one node in standby:

$ tux@dhcp-142:~$ sudo pcs node standby

Copy should continue without interruption. Confirm successful failover of resources: Before failover:
