Ukukhishwa kwephrojekthi ye-Stratis 3.3 kushicilelwe, kwathuthukiswa i-Red Hat kanye nomphakathi we-Fedora ukuze kuhlanganiswe futhi kube lula izindlela zokumisa nokuphatha iqoqo ledrayivu yasendaweni eyodwa noma ngaphezulu. I-Stratis inikeza izici ezifana nokwabiwa kwesitoreji esiguqukayo, izifinyezo, ubuqotho kanye nezendlalelo ze-caching. Ukusekelwa kwe-Stratis kuhlanganiswe ekusatshalalisweni kwe-Fedora ne-RHEL kusukela ekukhishweni kwe-Fedora 28 ne-RHEL 8.2. Ikhodi yephrojekthi isatshalaliswa ngaphansi kwelayisensi ye-MPL 2.0.
Uhlelo luphindaphinda kakhulu amakhono amathuluzi okuphatha ukwahlukanisa e-ZFS kanye ne-Btrfs athuthukisiwe, kodwa lusetshenziswa njengesendlalelo (i-stratisd daemon) esisebenza phezu kwesistimu encane ye-kernel ye-device-mapper. Linux (kusetshenziswa amamojula e-dm-thin, dm-cache, dm-thinpool, dm-raid, kanye ne-dm-integrity) kanye nohlelo lwefayela lwe-XFS. Ngokungafani ne-ZFS kanye ne-Btrfs, izingxenye ze-Stratis zisebenza kuphela endaweni yomsebenzisi futhi azidingi ukulayisha amamojula athile e-kernel. Ekuqaleni iphrojekthi yethulwa njengengadingi amakhono ochwepheshe bohlelo lokugcina ukuze iqondiswe.
I-D-Bus API kanye nensizakalo ye-cli kunikezwa ukuphathwa. I-Stratis ihlolwe ngamadivayisi we-block asekelwe ku-LUKS (izingxenye ezibethelwe), i-mdraid, i-dm-multipath, i-iSCSI, ivolumu enengqondo ye-LVM, kanye nama-HDD ahlukahlukene, ama-SSD kanye namadrayivu e-NVMe. Uma kunediski eyodwa echibini, i-Stratis ikuvumela ukuthi usebenzise izahluko ezinengqondo ngokusekelwa kwesithombe esifinyeziweyo ukuze ubuyisele emuva izinguquko. Uma ungeza amadrayivu amaningi endaweni yokubhukuda, ungakwazi ukuhlanganisa ngokunengqondo amadrayivu endaweni ehlangene. Izici ezifana ne-RAID, ukuminyanisa idatha, ukuphindaphinda kanye nokubekezelela amaphutha azikasekelwa, kodwa zihlelelwe ikusasa.
Enguqulweni entsha:
- Kungezwe ukwesekwa kokwandisa usayizi wamadivayisi angokoqobo, okukuvumela ukuthi ungeze isikhala sediski esengeziwe echibini le-Stratis elitholakala kudivayisi yokugcina (isibonelo, lapho kwandiswe i-RAID array).
- Umyalo othi "stratis pool extend-data" ungeziwe ukuze kungezwe isikhala sediski esengeziwe echibini lokugcina elithile elitholakale kwenye yamadivayisi. Ukuze kulandelwe izinguquko zosayizi wedivayisi, kufakwe isexwayiso esikhethekile emkhiqizweni womyalo othi "stratis pool list", futhi ulwazi mayelana nomehluko wosayizi wechibi kanye nedivayisi lungeziwe emyalweni othi "stratis blockdev list".
- Ukwabiwa kwesikhala okuthuthukisiwe kwemethadatha ehlobene namadivayisi okugcina kanye nokunikezwa okuncane. Lolu shintsho lunciphisa ukuqhekeka lapho kugcinwa imethadatha.
- Ukuhlolwa kwamafayela asebenzisekayo ohlaka lwe-Clevis, olusetshenziselwa ukubethela ngokuzenzakalelayo kanye nokususa ukubethela kwedatha kuma-disk partitions, sekuphinde kwasebenza. Ukuhlolwa manje kwenziwa njalo uma umyalo womsebenzisi udinga ukufinyelela ku-Clevis (ngaphambilini, ukuhlolwa kwenziwa kanye kuphela, lapho i-Stratis yethulwa). Lokhu kuxazulula izinkinga ngokufakwa kwe-Clevis ngemva kokuqaliswa kwe-stratisd.
