Ho kenngoa ha polokelo ea lintho ea LeoFS e ajoang, e tsamaellanang le bareki ba sebelisang S3, NFS
Ho ea ka Opennet: LeoFS - e ajoang polokelo ea lintho tse mamellang liphoso LeoFS, e lumellana le bareki ba sebelisang Amazon S3 API le REST-API, hape e tšehetsa mokhoa oa seva oa NFS. Ho na le lintlafatso tsa ho boloka lintho tse nyane le tse kholo haholo, ho na le mochini o hahelletsoeng ka har'a caching, 'me ho ka khoneha ho pheta-pheta polokelo lipakeng tsa litsi tsa data. Lipheo tsa morero li kenyelletsa ho fihlela ts'epo ea 99.9999999% ka ho pheta-pheta ho sa hlokahaleng le ho felisa ntlha e le 'ngoe ea ho hloleha. Khoutu ea projeke e ngotsoe ka Erlang.
LeoFS e na le likarolo tse tharo:
LeoFS Storage - e fana ka ts'ebetso ea ho eketsa, ho khutlisa le ho hlakola lintho le metadata, e ikarabella bakeng sa ho pheta-pheta, ho khutlisa le ho emisa likopo tsa bareki.
LeoFS Gateway - e sebeletsa likopo tsa HTTP mme e khutlisetsa likarabo ho bareki ba sebelisang REST-API kapa S3-API, e netefatsa caching ea data e hlokahalang haholo mohopolong le disk.
Motsamaisi oa LeoFS - e lekola ts'ebetso ea LeoFS Gateway le LeoFS Storage node, e lekola boemo ba li-node le ho hlahloba li-checksums. E netefatsa botšepehi ba data le ho fumaneha ha polokelo e phahameng.
Ka poso ena re tla kenya Leofs re sebelisa ansible-playbook le teko ea S3, NFS.
Haeba u leka ho kenya LeoFS u sebelisa libuka tsa lipapali tsa molao, u tla kopana le liphoso tse fapaneng: 1,2. Ka poso ena ke tla ngola se lokelang ho etsoa ho qoba liphoso tsena.
Moo o tla tsamaisa ansible-playbook, o hloka ho kenya netcat.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key [9c2615f32e81e6a1caf5]:
Secret Key [8aaaa35c1ad78a2cbfa1a6cd49ba8aaeb3ba39eb]:
Default Region [US]:
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]:
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: leofs
Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:
When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [No]:
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name [172.26.9.180]:
HTTP Proxy server port [8080]:
