Liricni uvod<\/h3>\n

\nDatote\u010dna smeti\u0161\u010de v na\u0161i organizaciji deluje na virtualnem stroju VMware ESXi 6 pod operacijskim sistemom Windows Server 2016. In to ni le smeti\u0161\u010de. To je stre\u017enik za izmenjavo datotek med strukturnimi enotami: tukaj poteka skupinsko delo, projektna dokumentacija in map\u0435 iz omre\u017enih skenerjev. Skratka, tukaj je vse delovno \u017eivljenje.<\/p>\n

In to skladi\u0161\u010de vsega delovnega \u017eivljenja je za\u010delo zastajati. Pri tem je gost lahko tiho obti\u010dal, ne da bi prizadel druge. Lahko je obti\u010dal skupaj s celotnim gosti\u0161\u010dem in, posledi\u010dno, vsemi drugimi gostovalnimi stroji. Lahko je obti\u010dal sam in obti\u010dal storitvi strank v vSphere: to pomeni, da so procesi drugih gostov ostali aktivni, stroji so delovali in odgovarjali, vendar pa smeti\u0161\u010de ni delovalo in vSphere Client se ni mogel povezati s h\u00f3stom. Skratka, nobene sistema nismo mogli ugotoviti. Zastoji so se lahko zgodili podnevi med \u0161ibko obremenitvijo. Lahko so se zgodili pono\u010di med ni\u010delno obremenitvijo. Lahko pono\u010di med diferencialnim varnostnim kopiranjem in srednjo obremenitvijo. Lahko med vikendi med popolnim varnostnim kopiranjem in visoko obremenitvijo. In opazila se je o\u010ditna degradacija situacije. Najprej se je to zgodilo enkrat na leto, nato enkrat na pol leta. Na koncu mojega potrpljenja - dvakrat na teden.
\nObto\u017eeval sem pomnilnik. Vendar mi niso dovolili ustaviti smeti\u0161\u010da niti med vikendi in izvesti Memtest. \u010cakali so na praznike. Med prazniki sem izvedel Memtest in... napak ni bilo najdenih.
\n<\/a><\/noindex>
\nZaznal sem presene\u010denje in se odlo\u010dil oditi na dopust. Med mojim dopustom ni bilo nobenega zastoja. In ko sem se v ponedeljek vrnil na delo - je smeti\u0161\u010de obti\u010dalo. Preneslo je popolno varnostno kopiranje in to\u010dno ob koncu obti\u010dalo. Tak\u0161no toplo pri\u010dakovanje po dopustu me je spodbudilo k odlo\u010ditvi, da fizi\u010dno prenesem diske z gostiteljske naprave na drugega h\u00f3st.<\/p>\n

In, \u010deprav je \u017ee dolgo znano, da prvega dne po dopustu ne smemo po\u010deti ni\u010d resnega, kljub temu, da sem se med potjo v slu\u017ebo vse poti sku\u0161al prepri\u010dati, da ne bom delal, me je moje ogor\u010denje ob novem zastoju izrinilo iz misli in moji nastavitvah ...<\/p>\n

Fizi\u010dni diski so bili preneseni na drugega h\u00f3st. Povezovanje je potekalo med delovanjem. V nastavitvah skladi\u0161\u010d na zavihku Drives<\/i> diskovi se pojavljuju. Na kartici Datastores<\/i> nema skladi\u0161ta na tim diskovima. Osve\u017ei<\/i> se ne pojavljuju. Naravno, prva reakcija je bila \u2014 Dodaj skladi\u0161te<\/i>. \u010carobnjak za dodavanje govori da to podr\u017eava. Naravno da podr\u017eava i VMFS. Nisam sumnjao u to. Brzi pregled poruka \u010darobnjaka na svakom koraku: Dalje, Dalje, Dalje, Zavr\u0161i. Pogled se nije ni bli\u017ee uhvatio za mali \u017euti krug sa uzvi\u010dnikom u donjem delu prozora jednog od koraka \u010darobnjaka.<\/p>\n

Na kraju \u010darobnjaka, novi Datastore pojavljuje se na listi\u2026 a zajedno s njim i Datastores s drugih fizi\u010dkih diskova.<\/p>\n

Prelazim na navigaciju kroz upravo dodati Datastore, a on\u2026 prazan. Naravno, ponovo sam bio zapanjen. 8 sati ujutro, prvih 15 minuta na poslu nakon odmora, \u010dak \u0161e\u0107er u kafi jo\u0161 nisam prome\u0161ao. I onda ovako ne\u0161to. Prva misao je bila \u2014 nisam izvadio pravi disk iz 'rodnog' hosta. Pogledao sam da li je tra\u017eeni Datastore prisutan u 'rodnom' hostu: ne, nije prisutan. Druga misao je bila: 'jebote!'. Nisam siguran, ali mislim da su tre\u0107a, \u010detvrta i bar peta misao bile iste.<\/p>\n

Da razjasnim sumnje, brzo sam instalirao sve\u017e ESXi, uzeo jedan obi\u010dan disk i, kako sam se ve\u0107 usredsredio, pro\u0161ao kroz korake \u010darobnjaka. Da. Prilikom dodavanja Datastore putem \u010darobnjaka dolazi do gubitka svih podataka na disku bez mogu\u0107nosti vra\u0107anja operacije i obnavljanja podataka. Kasnije sam pro\u010ditao na jednom forumu ocenu tog dizajna \u010darobnjaka: totalna glupost. I zaista sam se s tim veoma slo\u017eio.<\/p>\n

Od \u0161este \u2014 misli su pre\u0161le u konstruktivniji pravac. U redu. Inicijalizacija traje nekoliko sekundi \u010dak i za 3Tb disk. Zna\u010di, to je visoko nivo formatiranja. Zna\u010di, samo je prepisana tabela particija. Zna\u010di, podaci su i dalje tu. Zna\u010di, sada \u0107emo potra\u017eiti neki unformat i voala.<\/p>\n

Pokre\u0107em ma\u0161inu sa boot slike Strelec\u2026 I saznajem da programi za obnavljanje particija znaju sve osim VMFS. Na primer, poznaju particionu shemu Synology, ali VMFS \u2014 ne.<\/p>\n

Pretraga programa nije ohrabruju\u0107a: u najboljem slu\u010daju, GetDataBack i R.Saver nalaze NTFS particije sa \u017eivom strukturom direktorijuma i \u017eivim imenima fajlova. Ali to me ne zadovoljava. Potrebna su mi dva vmdk-fajla: sa sistemskim diskom i diskom za sme\u0107e.<\/p>\n

In this moment, I realize that I'm probably going to install Windows and recover from a file backup. At the same time, I remember that I had a DFS root there. And there was also an extremely complex and extensive access rights system for departmental folders. Not an option. The only time-acceptable option is to restore the system and data disk state with all the rights.<\/p>\n

Ponovno pretra\u017eivanje, forumi, KB-ovi i ponovo pla\u010d: VMware ESXi ne nudi mehanizam za oporavak podataka. Sve diskusijske teme imaju dva kraja: netko se oporavio uz pomo\u0107 skupi DiskInternals VMFS Recovery ili mu je pomogao stru\u010dnjak koji aktivno promovira svoje usluge. vmfs-tools<\/i> in dd<\/i>. The option to buy a DiskInternals VMFS Recovery license for $700 is not an option. Allowing an outsider from the 'territory of a potential enemy' access to corporate data is also not an option. However, it was discovered that VMFS partitions can also be read by UFS Explorer.<\/p>\n

DiskInternals VMFS Recovery<\/h3>\n

\nA trial version was downloaded and installed. The program successfully detected the empty VMFS partition:<\/p>\n

\"Obnavljanje
\n
\nU re\u017eimu Undelete (Fast Scan)<\/i> also found the worn Datastore with folders virtualnih naprav<\/a> containing disks:<\/p>\n

\"Obnavljanje
\n
\nThe preview showed that the files were alive:<\/p>\n

\"Obnavljanje
\n
\nMounting the partition in the system was successful, but for some unknown reason, all three folders contained the same virtual machine. Of course, by the law of meanness \u2014 not the one that was needed.<\/p>\n

Three lines of shame<\/b>The attempted disgraceful piracy of the software ended in failure. However, UFS Explorer was pirated.<\/p>\n

I have a very negative attitude towards software theft. Under no circumstances do I encourage the use of means to bypass protection against unauthorized use. \n<\/p><\/blockquote>\n

\nI was in a catastrophic situation and was not proud of the measures I resorted to.<\/p>\n

UFS Explorer<\/h3>\n

\nScanning the disk revealed the presence of 7 nodes. The number of nodes 'coincidentally' matched the number of *-flat.vmdk files found by VMFS Recovery:<\/p>\n

\"Obnavljanje
\n
\nComparing the sizes of the files and the sizes of the nodes also showed a match down to the byte. Additionally, the names of the *-flat.vmdk files were restored, and accordingly, their ownership to virtual machines.<\/p>\n

\"Obnavljanje
\n
\nVmdk datoteke v kontekstu ESXi sestojijo iz dveh datotek: to je datoteka z podatki (<ime naprave>-flat.vmdk) in datoteka 'fizi\u010dne' razporeditve diska (<ime naprave>.vmdk). \u010ce na lokalni napravi nalo\u017eite *-flat.vmdk datoteko v Datastore, jo ESXi ne bo prepoznal kot veljavno datoteko diska. V bazi znanja VMware je \u010dlanek o tem, kako ro\u010dno ustvariti opisno datoteko diska: kb.vmware.com\/s\/article\/1002511<\/a><\/noindex>, vendar mi tega ni bilo treba narediti, preprosto sem kopiral in prilepil vsebino ustreznih datotek iz obmo\u010dja predogleda vsebine datoteke v DiskInternals VMFS Recovery:<\/p>\n

\"Obnavljanje
\n
\nNakon 4 sata izvoza 2,5 TB \u010dvora iz UFS Explorer-a i 20 sati u\u010ditavanja u Datastore hipervizora, o\u0161te\u0107ene datoteke diskova su povezane s novo stvorenom virtualnom ma\u0161inom. Diskovi su se preuzeli. Gubici podataka nisu primje\u010deni.<\/p>\n
