Swift distributed storage adds storage nodes

Swift distributed storage add node requires new node information to be added to the ring record

1, add two nodes in the ring information

2. Balance Ring

[Email protected]:/etc/swift> sudo swift-ring-builder account.builder rebalance

Reassigned 262144 (100.00%) partitions. Balance is now 16.67.

-------------------------------------------------------------------------------

Note:balance of 16.67 indicates you should push this

Ring, wait at least 1 hours, and Rebalance/repush.

-------------------------------------------------------------------------------

[Email protected]:/etc/swift> sudo swift-ring-builder container.builder rebalance

Reassigned 262144 (100.00%) partitions. Balance is now 16.67.

-------------------------------------------------------------------------------

Note:balance of 16.67 indicates you should push this

Ring, wait at least 1 hours, and Rebalance/repush.

-------------------------------------------------------------------------------

[Email protected]:/etc/swift> sudo swift-ring-builder object.builder rebalance

Reassigned 262144 (100.00%) partitions. Balance is now 16.67.

-------------------------------------------------------------------------------

Note:balance of 16.67 indicates you should push this

Ring, wait at least 1 hours, and Rebalance/repush.

-------------------------------------------------------------------------------

[Email protected]:/etc/swift> sudo chown swift:swift *

Copy the ring file to all storage nodes

3. Configure the added storage node

Refer to previous articles configuring configuration 215 and 216, noting permissions for directories and files

Start Services 215 and 216

Then remember the other node restart service

Proxy node

[Email protected]:/etc/swift> sudo swift-init proxy restart

Signal Proxy-server pid:23568 signal:15

Proxy-server (23568) appears to has stopped

Starting proxy-server ... (/etc/swift/proxy-server.conf)

Storage node

# Swift-init All restart

Attention

server5:/# Chown-r SWIFT:SWIFT/SRV/NODE/SDB1

server6:/# Chown-r SWIFT:SWIFT/SRV/NODE/SDB1
