EMC clariion NAS increases Quta tree capacity operations

This time the operation is to increase the NAS space:

Do not add a new path, only increase the capacity of one tree, it is relatively simple, do not want to do on backup, if you add a new tree, you need to modify the DataList backup script.

The steps are as follows:

1) Increase the capacity of the file system

2) Increase the capacity of the Quta tree

Can be considered a branch of the file system, similar to Windows c,d disk, filesystem is the entire hard disk.

3) Increase the capacity of the checkpoint:

20% * File system capacity, only need to increase the CK1,CK2 will automatically increase.

4) About IP issues with access:

Operation only three steps, in the network can see the NAS has a lot of network segment IP, this is for different server communication, in [share] can see the configuration of CIFS and NFS, each tree will be configured "Access host" "Root host The IP in the "Read/write host" is the IP of the server and NAS communication, not the corresponding interface in the production Ip,nas and the IP traffic in the network interface above.

Add block and file-level transfer issues:

Sans are block-level:

Server and storage are connected via FC cable, the server is composed of Os+volume, volume has Flle system, both interact by I/O, block-level transmission.

NAS is file-level:

Server and NAS communicate via IP, file system is in Nas, both are file level communication.
