Pozdravljeni! Nedavno sem se spopadel z nalogo, ki se na prvi pogled zdi preprosta \u2014 povi\u0161anje velikosti diska na stre\u017eniku Linux brez prekinitve delovanja.<\/p>\n

Opis naloge<\/h4>\n

\nImam stre\u017enik v oblaku. V mojem primeru je to Google Cloud \u2014 Compute Engine. Operacijski sistem je Ubuntu. Trenutno je povezan disk velikosti 30 GB. Moja baza raste, datoteke se \u0161irijo, zato moram pove\u010dati velikost diska, recimo, na 50 GB. Pri tem ne izklapljamo ni\u010desar, ni\u010desar ne ponastavljamo.
\n<\/a><\/noindex>
\nPozor! Preden za\u010dnemo, naredimo varnostno kopijo vseh va\u017enih informacij!<\/b><\/p>\n

1. Najprej preverimo, koliko imamo skupnega prostega prostora. V Linux konzoli vnesemo:<\/p>\n

df -h<\/code><\/pre>\n
\n\"Kako
\nEnostavno povedano, imam skupaj 30 GB in zdaj prostih 7,9 GB. Potrebno je pove\u010dati.<\/i><\/p>\n
2. Nato grem v konzolo svojega ponudnika in pove\u017eem \u0161e nekaj GB. V Google Cloud je to enostavno, brez ponastavitve. Vstopim v Compute Engine -> Diski -> Izberem disk svojega stre\u017enika \u2014 temu bomo spremenili velikost:<\/p>\n
\"Kako
\nVstopim, kliknem 'Uredi' in pove\u010dam velikost diska na \u017eelene dimenzije (v mojem primeru na 50 GB).<\/i><\/p>\n
3. Zdaj imamo 50 GB. Preverimo to z stre\u017enikom<\/a> komandom:<\/p>\n
sudo fdisk -l<\/code><\/pre>\n
\n\"Kako
\nVidimo svoj novih 50 GB, vendar lahko trenutno uporabimo le 30 GB.<\/i><\/p>\n
4. Zdaj bomo odstranili trenutni 30 GB razdelek in ustvarili novega na 50 GB. Imate lahko ve\u010d razdelkov. Morda boste morali ustvariti tudi ve\u010d novih razdelkov. Za to operacijo bomo uporabili program fdisk<\/b>, ki omogo\u010da upravljanje z razdelki trdih diskov. Prav tako je pomembno razumeti, kaj so razdelki diska in zakaj jih potrebujemo \u2014 berite tukaj<\/a><\/noindex>. Za zagon programa fdisk<\/b> uporabimo ukaz:<\/p>\n
sudo fdisk \/dev\/sda<\/code><\/pre>\n
\n5. V interaktivnem na\u010dinu programa fdisk<\/b> izvedemo ve\u010d operacij. <\/p>\n
Najprej vnesemo:<\/p>\n
p<\/code><\/pre>\n
\n\"Kako
\nUkaz prika\u017ee seznam na\u0161ih trenutnih razdelkov. V mojem primeru je en razdelek na 30 GB in \u0161e 20 GB prostega prostora, \u010de to lahko tako re\u010demo.<\/i><\/p>\n
6. Nato vnesemo:<\/p>\n
d<\/code><\/pre>\n
\n\"Kako
\nOdstranimo trenutni razdelek, da ustvarimo novega na vseh 50 GB. Pred operacijo \u0161e enkrat preverimo, ali smo naredili varnostno kopijo pomembnih informacij!<\/b><\/i><\/p>\n
7. Nato programu dolo\u010dimo:<\/p>\n
n<\/code><\/pre>\n
\n\"Kako
\nUkaz ustvari nov razdelek. Vse parametre je najbolje nastaviti privzeto \u2014 lahko preprosto pritisnete Enter. \u010ce imate kak\u0161en poseben primer, navedite svoje parametre. Kot je razvidno iz posnetka zaslona, sem ustvaril razdelek na 50 GB \u2014 to, kar potrebujem.<\/i><\/p>\n
8. Na koncu programu dolo\u010dim:<\/p>\n
w<\/code><\/pre>\n
\n\"Kako
\nTa ekipa bele\u017ei spremembe in izide iz fdisk<\/b>. Ne prestra\u0161imo se, da branje tabelskih delov ni uspelo. Naslednja ukaz bo pomagala to popraviti. Ostalo je \u0161e malo.<\/i><\/p>\n
9. Iz\u0161li smo iz fdisk<\/b> in se vrnili na glavno linijo Linux. Nadaljujemo z vnosom, kot smo predhodno svetovali:<\/p>\n
sudo partprobe \/dev\/sda<\/code><\/pre>\n
\n\u010ce je vse potekalo uspe\u0161no, ne boste videli nobenega sporo\u010dila. \u010ce program partprobe<\/b>, ga namestite. Prav on partprobe<\/b> bo posodobil tabele delov, kar nam bo omogo\u010dilo \u0161iritev dela na 50 GB v \u017eivo. Nadaljujmo.<\/i><\/p>\n
Namig! Namestite partprobe<\/b> lahko takole:<\/p>\n
 apt-get install partprobe<\/code><\/pre>\n
<\/i>
\n10. Zdaj je treba ponovno dolo\u010diti velikost dela z uporabo programa resize2fs<\/b>. To bo izvedel v \u017eivo - pri meni so v tem trenutku celo skripte delale in zapisovale na disk. <\/p>\n
Program resize2fs<\/b> bodo prepisali metapodatke datote\u010dnega sistema. Za to uporabimo naslednji ukaz:<\/p>\n
sudo resize2fs \/dev\/sda1<\/code><\/pre>\n
\n\"Kako
\nTukaj je sda1 ime va\u0161ega dela. V ve\u010dini primerov je to sda1, vendar so mo\u017ene tudi izjeme. Bodite previdni. Na koncu je program spremenil velikost na\u0161ega dela. Mislim, da je to uspeh.<\/i><\/p>\n
11. Zdaj se prepri\u010dajmo, da se je velikost dela spremenila in zdaj imamo 50 GB. Za to ponovimo prvi ukaz:<\/p>\n
df -h<\/code><\/pre>\n
\n\"Kako
