How to fix failed VMFS datastore

How to fix failed VMFS datastore

Connect to ESXi via SSH

List all datastores to see the UUID of the problematic Datastore

# esxcli storage filesystem list

List active files in the datastore (the first column shows the required PID)

# lsof | grep '/ vmfs / volumes / 58580b99-a196935b-fa23-fc15b41d8300'

Replace 58580b99-a196935b-fa23-fc15b41d8300 with the UUID of Your problematic datastore

Kill each of the active PIDs in the failed datastore (They prevent You from unmounting the problematic datastore)

# kill 33172

Replace 33172 with the PID of Your active PIDs

Execute the command to unmount the datastore

# esxcli storage filesystem unmount -u 58580b99-a196935b-fa23-fc15b41d8300

Replace 58580b99-a196935b-fa23-fc15b41d8300 with the UUID of Your previously problematic datastore

Connect to ESXi and check the datastore, if necessary, mount datastore

Done
