Kazdy, kdo pracuje s virtualnimi stroji, se urcite setkal s neprijemnou situaci, kdy pri tvorbe VM podcenil diskove pozadavky, pripadne pozdeji vyvstal problem s nedostatkem mista.<\/p>\n

<\/p>\n

Referencnim modelem mi bude image od Oraclu (Oracle Developer Days<\/a>), ktera je k dispozici zdarma ke stazeni a uzivani (samozrejme pro testovaci ucely). Za svuj zivot tato image byla nekolikrat updatovana, aktualni verze je rok stara a pokud si chcete jen tak „stouchnout“ do enterprise databaze, bude to predstavovat asi nejlepsi volbu pri minimalnim usili \ud83d\ude09<\/p>\n

Po importu appliance do Virtualboxu je mozno videt podstrelena cisla 2 partition:<\/p>\n

\"\"<\/p>\n

V nastaveni jeste takto:<\/p>\n

\"\"<\/p>\n

Aaaaaa posledni nudny screen, na disku vypadame takhle:<\/p>\n

\"\"<\/p>\n

Posledni poznamka k „rozlozeni sil“ – mensi disk(master) obsahuje operacni system, vetsi pak \/home (kde jsou asi z duvodu prehlednosti nasackovane vsechny datafily + samotna databaze). Tedy klasicky dochazi misto v datove casti = 2.disk bude v hledacku pro akce pristi:<\/p>\n

\u00a0KROK 1<\/strong><\/p>\n

Prevod vmdk na vdi (spousteno z adresare nainstalovaneho Virtualboxu) :<\/p>\n

VBoxManage clonehd „C:\\vmware\\odd2b.vmdk“ „C:\\vmware\\odd2b.vdi“ –format vdi<\/span><\/strong><\/p>\n

\"\"<\/p>\n

KROK 2<\/strong><\/p>\n

Zmena velikosti virtualniho disku (hdb1 pro linux):<\/p>\n

VBoxManage modifyhd „C:\\vmware\\odd2b.vdi“ –resize 512000<\/span><\/strong><\/p>\n

\"\"<\/p>\n

KROK 3<\/strong><\/p>\n

Smazte odd2b.vmdk z disku (moznosti se zde vetvi, tohle je „macho“, primocara = ne nejelegantnejsi).<\/p>\n

Naklonujte vmdk do vdi:<\/p>\n

VBoxManage clonehd „C:\\vmware\\odd2b.vdi“ „C:\\vmware\\odd2b.vmdk“ –format vmdk<\/span><\/strong><\/p>\n

Objevi se chyba (UUID)<\/p>\n

\"\"<\/p>\n

Ta se lehce opravi uvolnenim<\/strong> chyboveho disku ve spravci virtualnich medii ve VirtualBoxu (CTRL+D)<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Chudak sirotek bude nasledne i odstranen<\/strong>:<\/p>\n

\"\"<\/p>\n

KROK 4
\n<\/strong><\/p>\n

Ve virtualnim stroji, zalozce Uloziste je nutne pridat druhy harddisk:<\/p>\n

\"\"<\/p>\n

Nanavigujeme na cerstve vytvoreny vmdk soubor a hned zkontrolujeme, zda zmena probehla bez problemu:<\/p>\n

\"\"<\/p>\n

Virtualni velikost napovida, ze probehla akce byla uspesna.<\/p>\n

Konec? Urcite ne \ud83d\ude00<\/p>\n

Prestoze je vyhled optimisticky:<\/p>\n

\"\"<\/p>\n

 <\/p>\n

(DOBROVOLNY) KROK 5<\/strong><\/p>\n

Poprve nabootujeme virtualni stroj, ciste pro overeni, ze jsme vetsi disk spravne vlozili \ud83d\ude42 . S velkou nadeji mackame za prikazem Enter…. a…. :<\/p>\n

Overeni, ze disk hdb je opravdu „velky“ \ud83d\ude42<\/p>\n

KROK 6<\/strong><\/p>\n

Kazdy si muze rozhodnout, jakym zpusobem, nastrojem, LiveCD, cimkoliv roztahne partitionu na celych 500GB. Zde popisu primocarou a nejjednodussi variantu – LiveCD GParted<\/a>.<\/p>\n

Stazene iso pripojime do nove pridane virtualni CD\/DVD mechaniky:<\/p>\n

\"\"<\/p>\n

Virtualni stroj po spusteni avizuje, ze se bude nahravat tato uzitecna linuxova distribuce:<\/p>\n

\"\"<\/p>\n

Po odklikani vseho defaultniho, spusteni GUI = automatickem spusteni GParted, vybereme cilovy disk = sdab:<\/p>\n

\"\"<\/p>\n

Tohle jsme tak nejak cekali \ud83d\ude42<\/p>\n

\"\"<\/p>\n

Naklikneme jiz alokovanou ext3 partition (sdb1) a zvolime „Resize\/Move“:<\/p>\n

\"\"<\/p>\n

Oramovanou casti sdb1 partitiony lze v nove vybehlem okne intuitivne roztahnout:<\/p>\n

\"\"<\/p>\n

Resize\/Move – a v horni casti programu Apply.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

KROK 7<\/strong><\/p>\n

Zaverecna verifikace, ze roztazeni partitiony bylo uspesne – z nabootovaneho virtualniho stroje:<\/p>\n
