Ka hoʻouka ʻana o ka waiho ʻana o ka LeoFS mea hoʻopaʻa hewa i hāʻawi ʻia, kūpono me nā mea kūʻai aku e hoʻohana ana iā S3, NFS

Wahi a Opennet: LeoFS - puʻunaue ʻia ka mālama ʻana i nā mea hewa LeoFS, kūpono me nā mea kūʻai aku e hoʻohana ana i ka Amazon S3 API a me REST-API, a kākoʻo pū i ke ʻano kikowaena NFS. Aia nā optimizations no ka mālama ʻana i nā mea liʻiliʻi a me nā mea nui loa, aia kahi mīkini caching i kūkulu ʻia, a hiki ke hana hou i ka waiho ʻana ma waena o nā kikowaena data. ʻO nā pahuhopu o ka papahana ka loaʻa ʻana o 99.9999999% hilinaʻi ma o ka hoʻopiʻi hou ʻana o nā kope a me ka hoʻopau ʻana i hoʻokahi wahi o ka hāʻule. Ua kākau ʻia ke code papahana ma Erlang.

Aia ʻo LeoFS i ʻekolu mau ʻāpana:

  • Waihona LeoFS - lawelawe i nā hana o ka hoʻohui, hoʻihoʻi a holoi ʻana i nā mea a me nā metadata, ke kuleana no ka hana hou ʻana, hoʻihoʻi hou a me ka hoʻopaʻa ʻana i nā noi o nā mea kūʻai aku.
  • LeoFS Gateway - lawelawe i nā noi HTTP a hoʻihoʻi hou i nā pane i nā mea kūʻai aku me ka hoʻohana ʻana iā REST-API a i ʻole S3-API, e hōʻoia i ka hoʻopaʻa ʻana i ka ʻikepili i makemake nui ʻia i ka hoʻomanaʻo a ma ka disk.
  • Luna LeoFS - nānā i ka hana o LeoFS Gateway a me LeoFS Storage nodes, nānā i ke kūlana o nā nodes a nānā i nā checksums. Hōʻoiaʻiʻo i ka paʻa o ka ʻikepili a me ka loaʻa ʻana o kahi mālama nui.

Ma kēia pou e hoʻokomo mākou i nā Leofs me ka hoʻohana ʻana i ka ansible-playbook a hoʻāʻo iā S3, NFS.

Inā ʻoe e hoʻāʻo e hoʻokomo iā LeoFS me ka hoʻohana ʻana i nā puke pāʻani mana, e hālāwai ʻoe i nā hewa like ʻole: 1,2. Ma kēia pou e kākau wau i nā mea e pono ai ke hana e pale aku i kēia mau hewa.

Ma kahi e holo ai ʻoe i ka ansible-playbook, pono ʻoe e hoʻokomo i ka netcat.

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 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
