The command output reports status as follows:
Condition Health Status
All monitored SMB services are up and running Up
The lwio service is running but one or more of the other services are down Degraded
The lwio service is down and one or more of the other services are down Down
Monitoring is disabled Not Monitored
The active Fusion Manager could not communicate with other file serving nodes in the cluster N/A
Disable monitoring and stop the SMB monitoring daemon:
ibrix_cifsmonitor -u [-h HOSTLIST]
Restart SMB service monitoring:
ibrix_cifsmonitor -c [-h HOSTLIST]
SMB shares
Windows clients access file systems through SMB shares. You can use the StoreAll GUI or CLI to
manage shares, or you can use the Microsoft Management Console interface. The SMB service
must be running when you add shares.
When working with SMB shares, you should be aware of the following:
•
The permissions on the directory exporting an SMB share govern the access rights that are
given to the Everyone user as well as to the owner and group of the share. Consequently, the
Everyone user may have more access rights than necessary. The administrator should set ACLs
on the SMB share to ensure that users have only the appropriate access rights. Alternatively,
permissions can be set more restrictively on the directory exporting the SMB share.
•
When the cluster and Windows clients are not joined in a domain, local users are not visible
when you attempt to add ACLs on files and folders in an SMB share.
•
A directory tree on an SMB share cannot be copied if there are more than 50 ACLs on the
share. Also, because of technical constraints in the SMB service, you cannot create subfolders
in a directory on an SMB share having more than 50 ACLs.
•
When configuring an SMB share, you can specify IP addresses or ranges that should be
allowed or denied access to the share. However, if your network includes packet filters, a
NAT gateway, or routers, this feature cannot be used because the client IP addresses are
modified while in transit.
•
You can use an SMB share as a DFS target. However, the SMB share does not support DFS
load balancing or DFS replication.
•
With the release of version 6.2, SMB shares support Large MTU, which provides a 1 MB
buffer for reads and writes. On the client, you must enable Large MTU in the registry to enable
support for Large MTU on the SMB server.
•
SMB shares support alternate data streams. SMB clients with files containing the Alternate
Data Streams type '$DATA' can be written to SMB shares. The files are stored on the StoreAll
file system in a special format and should only be handled by SMB clients.
