Arabera : β Akatsekiko tolerantzia duten objektuen biltegiratzea , Amazon S3 API eta REST-API erabiltzen dituzten bezeroekin bateragarria, eta NFS zerbitzari modua ere onartzen du. Objektu txikiak eta oso handiak gordetzeko optimizazioak daude, cache-mekanismoa barneratuta dago eta datu-zentroen artean biltegiratzea posible da. Proiektuaren helburuen artean, % 99.9999999ko fidagarritasuna lortzea bikoiztuen erreprodukzio erredundantearen bidez eta hutsegite puntu bakarra ezabatzea da. Proiektuaren kodea Erlang-en idatzita dago.
LeoFS hiru osagai ditu:
- β Objektuak eta metadatuak gehitzeko, berreskuratzeko eta ezabatzeko eragiketak egiten ditu, bezeroen eskaerak erreplikatzeaz, berreskuratzeaz eta ilaran jartzeaz arduratzen da.
- β HTTP eskaerak zerbitzatzen ditu eta bezeroei erantzunak birbideratzen ditu REST-API edo S3-API erabiliz, gehien behar diren datuen memorian eta diskoan gordetzea bermatzen du.
- β LeoFS Gateway eta LeoFS Storage nodoen funtzionamendua kontrolatzen du, nodoen egoera kontrolatzen du eta checksumak egiaztatzen ditu. Datuen osotasuna eta biltegiratze erabilgarritasun handia bermatzen du.
Post honetan Leofs instalatuko dugu ansible-playbook erabiliz eta S3, NFS probatu.
Jokalari ofizialak erabiliz LeoFS instalatzen saiatzen bazara, hainbat errore aurkituko dituzu: ,. Post honetan akats hauek saihesteko zer egin behar den idatziko dut.
Ansible-playbook exekutatzen duzun tokian, netcat instalatu behar duzu.

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

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.
