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

find least busy volume's id
2.c
send URI /<physical volume id>/<key>_<cookie>_<altKey>.<ext>
How to submit a content
1. send bytes to SeaweedFS, got <volume id, key uint64, cookie code>
store <key uint64, volume id uint32, cookie code uint32, ext>, and other information
To read a content
2. use logic volume id to lookup a <machine id>
render url as /<machine id>/<volume id>/<key>/<cookie>.ext
The directory server
0.init
load and collect <logic volume id, machine ids> mapping
1.on submit content
find a free logic volume id, start sending content to 3 machines
if all of them finishes, return <logic volume id, key, cookie code>
2.on read content
based on logic volume id, pick a machine with less load,
return <machine id>
