L\u00fc\u00fcriline sissejuhatus<\/h3>\n

\nFailide pr\u00fcgisort meie organisatsioonis t\u00f6\u00f6tab virtuaalmasinas VMware ESXi 6 Windows Server 2016'i all. Ja see ei ole lihtsalt pr\u00fcgisort. See on failivahetussev\u00f5ime struktuuri\u00fcksuste vahel: siin on nii koost\u00f6\u00f6, projektidokumendid kui ka kaustad v\u00f5rgu skanneritelt. \u00dches\u00f5naga, siin on kogu tootmiselu.<\/p>\n

Ja see kogu tootmiselu hoidmine hakkas k\u00fclmuma. K\u00fclastaja v\u00f5is rahulikult ise kinni j\u00e4\u00e4da, puudutamata teisi. Ta v\u00f5is k\u00fclmutada terve hosti ja seega k\u00f5ik teised k\u00fclalismasinad. Ta v\u00f5is ise kinni j\u00e4\u00e4da ja k\u00fclmutada vSphere kliendi teenuseid: st teiste k\u00fclaliste protsessid t\u00f6\u00f6tavad, masinad vastavad ja t\u00f6\u00f6tavad, kuid failide pr\u00fcgisort ei toimi ja vSphere Client ei saa hostiga \u00fchendust. \u00dches\u00f5naga, mingit s\u00fcsteemi tuvastada ei \u00f5nnestunud. Kinnij\u00e4\u00e4mised v\u00f5isid juhtuda p\u00e4eval n\u00f5rga koormuse ajal. Need v\u00f5isid juhtuda \u00f6\u00f6sel nullkoormuse ajal. Need v\u00f5isid juhtuda \u00f6\u00f6sel diferentsiaalse varundamise ja keskmise koormuse ajal. Need v\u00f5isid juhtuda n\u00e4dalavahetustel t\u00e4ieliku varundamise ja k\u00f5rge koormuse ajal. Ja olukord halvenes selgelt. Alguses juhtus see kord aastas, siis kord kuue kuu jooksul. Minu kannatuse l\u00f5puks - kaks korda n\u00e4dalas.
\nMa tunnistasin m\u00e4lu s\u00fc\u00fcdlaseks. Kuid plaan oli isegi n\u00e4dalavahetusel pr\u00fcgisordist sulgeda ja l\u00e4bi viia Memtest. Ootasin mai p\u00fchasid. Mai p\u00fcha ajal jooksin Memtest'i ja\u2026 vigu ei leitud.
\n<\/a><\/noindex>
\nOlin \u00fcllatunud ja otsustasin minna puhkusele. Kui olin puhkusel, ei olnud pr\u00fcgisordil \u00fchtegi kinnij\u00e4\u00e4mist. Ja kui esmasp\u00e4eval t\u00f6\u00f6le naasin, oli pr\u00fcgisort kinni. Ta talus t\u00e4ielikku varundamist ja just selle l\u00f5pul kinnij\u00e4\u00e4mine juhtus. Selline soe kohtumine puhkuselt ajendas mind otsustama f\u00fc\u00fcsiliselt viia k\u00fclalismasinate kettad teise hosti.<\/p>\n

Ja kuigi juba ammu on teada, et esimesel p\u00e4eval p\u00e4rast puhkust ei tohiks midagi t\u00f5sist teha, kuigi ma kogu tee t\u00f6\u00f6le seadsin end \u00fcles mitte t\u00f6\u00f6tama, ajas minu rahulolematus j\u00e4rgmise kinnij\u00e4\u00e4mise h\u00e4irima mu m\u00f5tted ja seadistused.<\/p>\n

F\u00fc\u00fcsilised kettad viidi teise hosti. \u00dchendamine kuumalt. Salvestusseadiste seadetes vahekaart Kettad<\/i> ilmuvad kettad. Vahekaardil Andmete salvestusruumid<\/i> need kettad ei kuvata. Uuenda<\/i> \u2014 ei ilmu. Noh, esmane reaktsioon \u2014 Lisa salvestusruumi<\/i>. Lisamise viisard \u00fctleb, et see toetab. Muidugi toetab ka VMFS. Ma ei kahtlenudki. Kiire \u00fclevaade viisaardi s\u00f5numitest igal sammul: J\u00e4rgmine, J\u00e4rgmine, J\u00e4rgmine, L\u00f5pp. Vaade isegi ei seostunud v\u00e4ikese kollase ringiga, mille sees on h\u00fc\u00fcum\u00e4rk \u00fchel viisaardi sammul.<\/p>\n

Viisardi l\u00f5petamisel ilmus v\u00e4rske andmete salvestusruum nimekirja... ning koos sellega ka Andmete salvestusruumid teistelt f\u00fc\u00fcsilistelt kettadelt.<\/p>\n

Liigun \u00e4sja lisatud andmete salvestusruumi navigeerimise juurde, kuid see on... t\u00fchi. Loomulikult tabas mind j\u00e4rjekordne \u00fcllatus. Kell on 8 hommikul, t\u00f6\u00f6p\u00e4eva esimesed 15 minutit p\u00e4rast puhkust, isegi suhkur kohvis pole veel segatud. Ja siis selline asi. Esimene m\u00f5te oli \u2014 vale ketas t\u00f5mmatud \u00abema\u00bb hostist. Kontrollisin, kas otsitav andmete salvestusruum on \u00abema\u00bb hostis: ei, pole olemas. Teine m\u00f5te oli: \u00abm**t!\u00bb. Ei ole kindel, aga mulle tundub, et kolmas, neljas ja v\u00e4hemalt viies m\u00f5te olid samad.<\/p>\n

Kahtluste hajutamiseks paigaldasin kiiresti proovimiseks uue ESXi, v\u00f5tsin sihitava ketta ja, juba s\u00fcvenedes, l\u00e4ksin viisaardi samme l\u00e4bi. Jah. Andmete salvestusruumi lisamisel viisaardi abil kaovad k\u00f5ik andmed kettalt, ilma v\u00f5imaluseta operatsiooni tagasi p\u00f6\u00f6rata v\u00f5i andmeid taastada. Hiljem lugesin \u00fchel foorumil hinnangut sellise viisaardi kujunduse kohta: shitsome crap. Ja n\u00f5ustusin selle arvamusega v\u00e4ga.<\/p>\n

Alates kuuendast \u2014 m\u00f5tted voolasid konstruktiivsematesse suundadesse. Okei. Algatus v\u00f5tab vaid m\u00f5ned sekundid isegi 3Tb kettale. T\u00e4hendab, see on k\u00f5rgema taseme vormindamine. Seega oli lihtsalt jaotustabel kirjutatud \u00fcle. Seega on andmed endiselt seal. Seega, n\u00fc\u00fcd otsime mingisugust unformat ja voila.<\/p>\n

Laadin masina Strelec'i k\u00e4ivituspildist... Ja selgitan, et taastamisprogrammid tunnevad k\u00f5ike, v\u00e4lja arvatud VMFS. N\u00e4iteks tunnevad nad Synology jaotust, aga VMFS'i mitte.<\/p>\n

Programmide valimine ei ole lohutav: parimal juhul leiavad GetDataBack ja R.Saver NTFS jaotuseid elava katalooge struktuuri ja elavate failide nimedega. Kuid mind see ei rahulda. Mul on vaja kahte vmdk-faili: \u00fche s\u00fcsteemi ketta ja \u00fche pr\u00fcgifailide kettaga.<\/p>\n

Ja saan aru, et paistab, et pean n\u00fc\u00fcd installima Windowsi ja taastama failibackup'ist. Samal ajal meenub, et mul oli seal DFS juur. Ja t\u00e4iesti ulatuslik ja keeruline kaustade \u00f5iguste s\u00fcsteem. See ei sobi. Ainus ajaliselt vastuv\u00f5etav variant on s\u00fcsteemi ja andmete oleku ning k\u00f5igi \u00f5iguste taastamine.<\/p>\n

J\u00e4lle Google'i otsing, foorumid, KB-artiklid ja taas Jarosslavna nutmine: VMware ESXi ei paku andmete taastamise mehhanismi. K\u00f5ik aruteluteemad l\u00f5ppevad kahe v\u00f5imalusega: keegi on taastunud kallima DiskInternals VMFS Recovery abil v\u00f5i on kellelegi abiks olnud aktiivselt oma teenuseid reklaamiv spetsialist. vmfs-tools<\/i> ja dd<\/i>. DiskInternals VMFS Recovery litsentsi ostmise variant 700 dollari eest ei sobi. Kolmanda isiku juurdep\u00e4\u00e4s \u201epotentsiaalsest vaenlasest territooriumilt\u201c ettev\u00f5tte andmetele \u2014 samuti ei sobi. Kuid leiti, et VMFS jaotisi oskab lugeda ka UFS Explorer.<\/p>\n
