On MSP-enabled systems, the 'Partial ofsck' feature enables the filesystem checker on a specific storage group while allowing other storage groups to remain in read-write mode. The specified storage group undergoing ofsck will be set to read-only mode.
Partial filesystem checker (ofsck) can be run from maintenance CLI with the option --partial.
(Ex: maintenance --filesystem --start_scan --storage_group DefaultGroup --partial. This will run ofsck on DefaultGroup and other storage groups are in read-write mode).
See the Quest QoreStor Command Line Reference Guide for details.
Only one storage group is allowed to run for this ofsck at a time. Additionally, only local storage groups are supported; cloud storage groups are not supported.
While this ofsck is run on a specific storage group, all config updates that requires this storage group are disabled. (Ex: Adding containers to this storage group)
QoreStor supports the following file system protocols. The Rapid Data Access (RDA) protocols below provide a logical disk interface that can be used with network storage devices to store data and support data storage operation.
- Network File System (NFS)
- Common Internet File System (CIFS)
- Rapid Data Access (RDA)
- Rapid NFS
- Rapid CIFS
- RDA with OpenStorage Technology (OST)
- RDA with NetVault
- RDA with vRanger
- The virtual tape library (VTL) tape access protocols:
- Network Data Management Protocol (NDMP)
- Internet Small Computer System Interface (iSCSI)
- Other supported access protocols
The Common Internet File System (CIFS) remote file access protocol is supported by QoreStor, and is also known as a Server Message Block (SMB). SMB occurs more commonly than the Network File System (NFS) protocol on systems that run the Microsoft Windows operating system. CIFS allows programs to request files or services on remote computers.
CIFS also uses the client-server programming model, whereby the client requests access to a file or passes a message to a program running on the server. Servers review all requested actions and return a response. CIFS is a public (or open) variation of the SMB that was originally developed and used by Microsoft.

NOTE: QoreStor currently supports version 2.0 and 3.0 of the Server Message Block (SMB). |
QoreStor supports the use of access control lists (ACLs) for CIFS and share-level permissions. By definition, an ACL is simply a list of permissions that can be associated with any network resource.
Each ACL can contain access control entries (ACEs) that define or describe the permissions for an individual user or a group of users. An ACL can consist of zero (meaning that all users have access) or a number of ACEs that define specific permissions on a per-user or per-group basis.
|
|
NOTE:If an ACE list is empty (meaning that it contains zero entries), this means that all access requests will be granted. |
An ACL describes the entities that are allowed to access a specific resource. ACLs are a built-in access control mechanism in the Windows operating systems.

NOTE: QoreStor supports setting up share-level permissions for a CIFS share using a Microsoft Windows administrative tool. Share-level permissions let you control access to shares. For more information, see Configuring share-level security for CIFS shares. |
