Kutulutsidwa kwa pulojekiti ya Stratis 3.3 kwasindikizidwa, kopangidwa ndi Red Hat ndi gulu la Fedora kuti agwirizanitse ndi kuphweka njira zokonzekera ndi kuyang'anira dziwe la ma drive amodzi kapena angapo amderalo. Stratis imapereka zinthu monga kugawa kosungirako kosinthika, zithunzithunzi, kukhulupirika ndi magawo a caching. Thandizo la Stratis laphatikizidwa mu magawo a Fedora ndi RHEL kuyambira kutulutsidwa kwa Fedora 28 ndi RHEL 8.2. Khodi ya polojekitiyi imagawidwa pansi pa layisensi ya MPL 2.0.
Dongosololi limatengera luso lake zida zotsogola zowongolera magawo a ZFS ndi Btrfs, koma zimayikidwa mu mawonekedwe a wosanjikiza (stratisd daemon) womwe ukuyenda pamwamba pa kachipangizo kakang'ono ka makina a Linux kernel (ma module dm-thin, dm). -cache, dm-thinpool, dm- raid ndi dm-integrity) ndi fayilo ya XFS. Mosiyana ndi ZFS ndi Btrfs, zigawo za Stratis zimangoyendetsa malo ogwiritsira ntchito ndipo sizifuna kukweza ma module a kernel. Pulojekitiyi idawonetsedwa poyamba ngati yosafunikira ziyeneretso za katswiri wamakina osungira kuti aziwongolera.
D-Bus API ndi cli utility amaperekedwa kwa kasamalidwe. Stratis yayesedwa ndi zida za block kutengera LUKS (encrypted partitions), mdraid, dm-multipath, iSCSI, LVM logical volumes, komanso ma HDD osiyanasiyana, SSD ndi NVMe drive. Ngati pali disk imodzi mu dziwe, Stratis imakulolani kuti mugwiritse ntchito magawo omveka bwino ndi chithandizo chazithunzi kuti musinthe kusintha. Mukawonjezera ma drive angapo padziwe, mutha kuphatikiza ma drivewo pamalo olumikizana. Zinthu monga RAID, kuponderezana kwa data, kuchotsera ndi kulolerana zolakwa sizikuthandizidwabe, koma zakonzedwa mtsogolo.
Mu mtundu watsopano:
- Thandizo lowonjezera pakukulitsa kukula kwa zida zakuthupi, kukulolani kuti muwonjezere malo owonjezera a disk ku dziwe la Stratis lomwe limapezeka pa chipangizo chosungira (mwachitsanzo, pakukulitsa gulu la RAID).
- Anawonjezera lamulo la "stratis pool extend-data" kuti muwonjezere malo owonjezera a disk omwe amawoneka pa chipangizo chimodzi ku dziwe losungirako. Kuti muwone kusintha kwa kukula kwa chipangizocho, chenjezo lapadera lawonjezedwa pazotsatira za lamulo la "stratis pool list", ndipo zambiri zokhudzana ndi kusiyana kwa dziwe ndi kukula kwa chipangizo chawonjezedwa ku lamulo la "stratis blockdev list".
- Kugawidwa bwino kwa malo kwa metadata yokhudzana ndi zida zosungirako komanso kugawa kosungirako kosinthika ("kuchepa kwapang'onopang'ono"). Kusinthaku kunachepetsa kugawikana posunga metadata.
- Cheke cha mafayilo omwe angagwiritsidwe ntchito a Clevis framework, omwe amagwiritsidwa ntchito polemba ndi kubisa deta pamagawo a disk, adakonzedwanso. Cheke tsopano ikuchitika nthawi iliyonse pamene lamulo la wosuta likufuna kuyitanira kwa Clevis (m'mbuyomu chekecho chinkachitika kamodzi kokha, pamene Stratis inayambika), yomwe imathetsa mavuto pogwiritsa ntchito Clevis atayikidwa stratisd itayamba.
