An N8000 file system can be used when offline command to query file system flag: echo "8192B.p S" | fsdb -t vxfs / dev / vx / rdsk / sfsdg / sfsvol | grep flag Where sfsvol is the name of the file system and may appear as flsgs 0 mod 0 Clean 3c or flags 4000 mod clean 3c if flags last bit is 0, then the file system is set.

Info Replication supports copying the data at the same time using the home directory, extended attributes, ACL (access control list), WORM, and CIFS. NFS configuration information is also copied to the slave. When a disaster occurs, the master and slave stations can quickly take over after the switchover.

In backup design, the required capacity for backup data (without deduplication) on site A is 3000GB and the required capacity for backup data (without deduplication) on site B is 1500GB. It is required to replicate the backup date from site B to site A, the deduplication ratio for replication is 3. The back-end capacity on site A should be no less than (Ignore redundancy ratio):

Scale out is a scale-out architecture that upgrades storage systems typically by increasing the number of nodes by expanding more controllers to meet user data growth demand. Huawei OceanStor V3 storage system supports the use of smart IP card to achieve IP scale out.

Because the first three nodes of Huawei OceanStor 9000 form an ISM cluster, you need to connect NIC0 of the first three storage nodes to the management switch.

In Huawei OceanStor 9000, the client that processes the write request performs data fragmentation according to the protection level specified in the file, divides the data chip, writes the corresponding node on power-saving memory, and then calculates the parity of each node data pieces, and writes to each node's power-saving memory. After the node writes the power-save memory, the write operation is successful.
