64 32G volumes consumes 10G memory
|
||||
Each volume has 25M index, so each cost 160MB memory
|
||||
|
||||
|
||||
|
||||
Things happened when I use lots of threads ( almost 120 ) keeping read file from SeaweedFS.
|
||||
But I'm not so familiar with linux so I can't tell you exactly what happened.
|
||||
Next I'll show you things I know , if you need more info , contact me
|
||||
|
||||
My SeaweedFS version is about 0.12

1. each file can choose the replication factor
|
||||
2. replication granularity is in volume level
|
||||
3. if not enough spaces, we can automatically decrease some volume's the replication factor, especially for cold data
|
||||
4. plan to support migrating data to cheaper storage
|
||||
5. plan to manual volume placement, access-based volume placement, auction based volume placement
|
||||
|
||||
When a new volume server is started, it reports
|
||||
1. how many volumes it can hold
|
||||
2. current list of existing volumes and each volume's replication type
|
||||
Each volume server remembers:
|
||||
1. current volume ids
|
||||
2. replica locations are read from the master
|
||||
|
||||
The master assign volume ids based on
|
||||
1. replication factor
|
||||
data center, rack
|
||||
2. concurrent write support
|
||||
On master, stores the replication configuration
|
||||
{
|
||||
replication:{
|
||||
{type:"00", min_volume_count:3, weight:10},
|
||||
{type:"01", min_volume_count:2, weight:20},
|
||||
{type:"10", min_volume_count:2, weight:20},
|
||||
{type:"11", min_volume_count:3, weight:30},
|
||||
{type:"20", min_volume_count:2, weight:20}
|
||||
},
|
||||
port:9333,
|
||||
}
|
||||
Or manually via command line
|
||||
1. add volume with specified replication factor
|
||||
2. add volume with specified volume id
|
||||
|
||||
|
||||
If duplicated volume ids are reported from different volume servers,
|
||||
the master determines the replication factor of the volume,
|
||||
if less than the replication factor, the volume is in readonly mode
|
||||
if more than the replication factor, the volume will purge the smallest/oldest volume
|
||||
if equal, the volume will function as usual
|
||||
|
||||
|
||||
Use cases:
|
||||
on volume server
|
||||
1. weed volume -mserver="xx.xx.xx.xx:9333" -publicUrl="good.com:8080" -dir="/tmp" -volumes=50
|
||||
on weed master
|
||||
1. weed master -port=9333
|
||||
generate a default json configuration file if doesn't exist
|
||||
|
||||
Bootstrap
|
||||
1. at the very beginning, the system has no volumes at all.
|
||||
When data node starts:
|
||||
1. each data node send to master its existing volumes and max volume blocks
|
||||
2. master remembers the topology/data_center/rack/data_node/volumes
|
||||
for each replication level, stores
|
||||
volume id ~ data node
|
||||
writable volume ids
|
||||
If any "assign" request comes in
|
||||
1. find a writable volume with the right replicationLevel
|
||||
2. if not found, grow the volumes with the right replication level
|
||||
3. return a writable volume to the user
|
||||
|
||||
|
||||
for data node:
|
||||
0. detect existing volumes DONE
|
||||
1. onStartUp, and periodically, send existing volumes and maxVolumeCount store.Join(), DONE
|
||||
2. accept command to grow a volume( id + replication level) DONE
|
||||
/admin/assign_volume?volume=some_id&replicationType=01
|
||||
3. accept setting volumeLocationList DONE
|
||||
/admin/set_volume_locations_list?volumeLocationsList=[{Vid:xxx,Locations:[loc1,loc2,loc3]}]
|
||||
4. for each write, pass the write to the next location, (Step 2)
|
||||
POST method should accept an index, like ttl, get decremented every hop
|
||||
for master:
|
||||
1. accept data node's report of existing volumes and maxVolumeCount ALREADY EXISTS /dir/join
|
||||
2. periodically refresh for active data nodes, and adjust writable volumes
|
||||
3. send command to grow a volume(id + replication level) DONE
|
||||
5. accept lookup for volume locations ALREADY EXISTS /dir/lookup
|
||||
6. read topology/datacenter/rack layout
|
||||
|
||||
An algorithm to allocate volumes evenly, but may be inefficient if free volumes are plenty:
|
||||
input: replication=xyz
|
||||
algorithm:
|
||||
ret_dcs = []
|
||||
foreach dc that has y+z+1 volumes{
|
||||
ret_racks = []
|
||||
foreach rack with z+1 volumes{
|
||||
ret = select z+1 servers with 1 volume
|
||||
if ret.size()==z+1 {
|
||||
ret_racks.append(ret)
|
||||
}
|
||||
}
|
||||
randomly pick one rack from ret_racks
|
||||
ret += select y racks with 1 volume each
|
||||
if ret.size()==y+z+1{
|
||||
ret_dcs.append(ret)
|
||||
}
|
||||
}
|
||||
randomly pick one dc from ret_dcs
|
||||
ret += select x data centers with 1 volume each
|
||||
|
||||
A simple replica placement algorithm, but may fail when free volume slots are not plenty:
|
||||
ret := []volumes
|
||||
dc = randomly pick 1 data center with y+z+1 volumes
|
||||
rack = randomly pick 1 rack with z+1 volumes
|
||||
ret = ret.append(randomly pick z+1 volumes)
|
||||
ret = ret.append(randomly pick y racks with 1 volume)
|
||||
ret = ret.append(randomly pick x data centers with 1 volume)

Design for SeaweedFS security
|
||||
|
||||
Design Objectives
|
||||
Security can mean many different things. The original vision is that: if you have one machine lying around
|
||||
somewhere with some disk space, it should be able to join your file system to contribute some disk space and
|
||||
network bandwidth, securely!
|
||||
|
||||
To achieve this purpose, the security should be able to:
|
||||
1. Secure the inter-server communication. Only real cluster servers can join and communicate.
|
||||
2. allow clients to securely write to volume servers
|
||||
|
||||
Non Objective
|
||||
Multi-tenant support. Avoid filers or clients cross-updating files.
|
||||
User specific access control.
|
||||
|
||||
Design Architect
|
||||
master, and volume servers all talk securely via 2-way SSL for admin operations.
|
||||
upon joining, master gives its secret key to volume servers.
|
||||
filer or clients talk to master to get secret key, and use the key to generate JWT to write on volume server.
|
||||
A side benefit:
|
||||
a time limited read feature?
|
||||
4. volume server needs to expose https ports
|
||||
|
||||
HTTP Connections
|
||||
clear http
|
||||
filer~>master, need to get a JWT from master
|
||||
filer~>volume
|
||||
2-way https
|
||||
master~ssl~>volume
|
||||
volume~ssl~>master
|
||||
|
||||
file uploading:
|
||||
when volume server starts, it asks master for the secret key to decode JWT
|
||||
when filer/clients wants to upload, master generate a JWT
|
||||
filer~>volume(public port)
|
||||
master~>volume(public port)
|
||||
|
||||
Currently, volume server has 2 ip addresses: ip and publicUrl.
|
||||
The ip is for admin purpose, and master talk to volume server this way.
|
||||
The publicUrl is for clients to access the server, via http GET/POST/DELETE etc.
|
||||
The write operations are secured by JWT.
|
||||
clients talk to master also via https? possible. Decide on this later.
|
||||
|
||||
Dev plan:
|
||||
1. volume server separate admin from public GET/POST/DELETE handlers
|
||||
The step 1 may be good enough for most use cases.
|
||||
|
||||
If 2-way ssl are still needed
|
||||
2. volume server add ssl support
|
||||
3. https connections to operate on volume servers
