Bol zverejnen\u00fd v\u00fdstup projektu Stratis 3.0, ktor\u00fd vyv\u00edja spolo\u010dnos\u0165 Red Hat a komunita Fedora za \u00fa\u010delom unifik\u00e1cie a zjednodu\u0161enia n\u00e1strojov na konfigur\u00e1ciu a spr\u00e1vu skupiny jedn\u00e9ho alebo viacer\u00fdch miestnych \u00falo\u017e\u00edsk. Stratis poskytuje mo\u017enosti ako dynamick\u00e9 prerozdelenie priestoru v \u00falo\u017eisku, sn\u00edmky, zabezpe\u010denie integrity a vytv\u00e1ranie vrstiev pre vyrovn\u00e1vaciu pam\u00e4\u0165. Podpora Stratis je integrovan\u00e1 v distrib\u00faci\u00e1ch Fedora a RHEL od vydania Fedora 28 a RHEL 8.2. K\u00f3d projektu je distribuovan\u00fd pod licenciou MPL 2.0. <\/p>\n

Syst\u00e9m sa v mnohom pren\u00e1\u0161a vo svojich mo\u017enostiach na roz\u0161\u00edren\u00e9 n\u00e1stroje na spr\u00e1vu oddielov ZFS a Btrfs, ale je realizovan\u00fd vo forme vrstvy (d\u00e9mon stratisd), ktor\u00e1 pracuje nad podsystemom device-mapper jadra Linux (pou\u017e\u00edvaj\u00fa sa moduly dm-thin, dm-cache, dm-thinpool, dm-raid a dm-integrity) a s\u00faborov\u00fdm syst\u00e9mom XFS. Na rozdiel od ZFS a Btrfs, komponenty Stratis funguj\u00fa iba v priestore pou\u017e\u00edvate\u013ea a nevy\u017eaduj\u00fa na\u010d\u00edtanie \u0161pecifick\u00fdch modulov jadra. Projekt sa p\u00f4vodne prezentuje ako nevy\u017eaduj\u00faci odborn\u00e9 znalosti na spr\u00e1vu syst\u00e9mov ukladania. <\/p>\n

Na spr\u00e1vu sa poskytuje D-Bus API a cli-n\u00e1stroj. Funk\u010dnos\u0165 Stratis bola testovan\u00e1 s blokov\u00fdmi zariadeniami zalo\u017een\u00fdmi na LUKS (\u0161ifrovan\u00e9 oddiely), mdraid, dm-multipath, iSCSI, logick\u00fdmi zv\u00e4zkami LVM, ako aj s r\u00f4znymi HDD, SSD a NVMe \u00falo\u017eiskami. Pri pr\u00edtomnosti jedn\u00e9ho disku v poole Stratis umo\u017e\u0148uje pou\u017e\u00edva\u0165 logick\u00e9 oddiely s podporou sn\u00edmok na n\u00e1vrat zmien. Pri prid\u00e1van\u00ed viacer\u00fdch \u00falo\u017e\u00edsk do poolu sa objavuje mo\u017enos\u0165 logick\u00e9ho zl\u00fa\u010denia \u00falo\u017e\u00edsk do s\u00favislej oblasti. Tak\u00e9to mo\u017enosti, ako RAID, kompresia \u00fadajov, deduplik\u00e1cia a organiz\u00e1cia odolnosti vo\u010di poruch\u00e1m zatia\u013e nie s\u00fa podporovan\u00e9, ale s\u00fa napl\u00e1novan\u00e9 do bud\u00facnosti. <\/p>\n
