Hej alla! Jag st\u00f6tte nyligen p\u00e5 en uppgift som vid f\u00f6rsta anblick verkade enkel \u2014 att \u00f6ka storleken p\u00e5 en disk p\u00e5 en Linux-server \"live\".<\/p>\n

Uppgiftsbeskrivning<\/h4>\n

\nDet finns en server i molnet. I mitt fall \u00e4r det Google Cloud \u2014 Compute Engine. Operativsystemet \u00e4r Ubuntu. Just nu har jag anslutit en disk p\u00e5 30 GB. Min databas v\u00e4xer, filerna blir st\u00f6rre, s\u00e5 jag beh\u00f6ver \u00f6ka diskstorleken, s\u00e4g till 50 GB. Under tiden st\u00e4nger vi inte av n\u00e5got och vi startar inte om n\u00e5got.
\n<\/a><\/noindex>
\nObservera! Innan vi b\u00f6rjar, ta en backup av all viktig information!<\/b><\/p>\n

1. F\u00f6rst ska vi kontrollera hur mycket ledigt utrymme vi har totalt. I Linux-konsolen skriver vi:<\/p>\n

df -h<\/code><\/pre>\n
\n\"Hur
\nEnkelt sagt, jag har totalt 30 GB och 7.9 GB \u00e4r nu ledigt. Det beh\u00f6ver \u00f6kas.<\/i><\/p>\n
2. N\u00e4sta steg \u00e4r att via min hostings konsol ansluta lite fler GB. I Google Cloud g\u00f6rs detta enkelt, utan omstart. Jag g\u00e5r till Compute Engine -> Disken -> V\u00e4ljer serverns disk \u2014 d\u00e4r \u00e4ndrar vi storleken:<\/p>\n
\"Hur
\nJag g\u00e5r in, klickar p\u00e5 \"Redigera\" och \u00f6kar diskens storlek till de n\u00f6dv\u00e4ndiga m\u00e5tten (i mitt fall, till 50 GB).<\/i><\/p>\n
3. S\u00e5 nu har vi 50 GB. L\u00e5t oss kontrollera detta p\u00e5 servern<\/a> med kommandot:<\/p>\n
sudo fdisk -l<\/code><\/pre>\n
\n\"Hur
\nVi ser v\u00e5ra nya 50 GB, men hittills kan vi endast anv\u00e4nda 30 GB.<\/i><\/p>\n
4. Nu tar vi bort den aktuella 30 GB partitionen och skapar en ny p\u00e5 50 GB. Du kan ha flera partitioner. Kanske beh\u00f6ver du ocks\u00e5 skapa flera nya partitioner. F\u00f6r denna operation kommer vi att anv\u00e4nda programmet fdisk<\/b>, som till\u00e5ter oss att hantera h\u00e5rddiskpartitioner. Det \u00e4r ocks\u00e5 viktigt att f\u00f6rst\u00e5 vad diskpartitioner \u00e4r och varf\u00f6r de beh\u00f6vs \u2014 l\u00e4s ). Ett typiskt exempel p\u00e5 anv\u00e4ndning:<\/a><\/noindex>. F\u00f6r att starta programmet fdisk<\/b> anv\u00e4nder vi kommandot:<\/p>\n
sudo fdisk \/dev\/sda<\/code><\/pre>\n
\n5. Inuti programmets interaktiva l\u00e4ge fdisk<\/b> utf\u00f6r vi n\u00e5gra operationer. <\/p>\n
F\u00f6rst skriver vi in:<\/p>\n
p<\/code><\/pre>\n
\n\"Hur
\nKommandot visar en lista \u00f6ver v\u00e5ra aktuella partitioner. I mitt fall en partition p\u00e5 30 GB och ytterligare 20 GB i fri tillg\u00e5ng, om man s\u00e5 vill s\u00e4ga.<\/i><\/p>\n
6. Sedan skriver vi in:<\/p>\n
d<\/code><\/pre>\n
\n\"Hur
\nVi tar bort den nuvarande partitionen f\u00f6r att skapa en ny p\u00e5 alla 50 GB. Innan operationen dubbelkollar vi att vi har gjort en backup av viktig information!<\/b><\/i><\/p>\n
7. Vidare ger vi programmet f\u00f6ljande anvisningar:<\/p>\n
n<\/code><\/pre>\n
\n\"Hur
\nKommandot skapar en ny partition. Alla inst\u00e4llningar b\u00f6r h\u00e5llas som standard \u2014 man kan helt enkelt trycka p\u00e5 Enter. Om du har n\u00e5gon speciell situation, anger du dina egna inst\u00e4llningar. Som syns p\u00e5 sk\u00e4rmdumpen har jag skapat en partition p\u00e5 50 GB \u2014 precis vad jag beh\u00f6ver.<\/i><\/p>\n
8. Slutligen anger jag f\u00f6ljande till programmet:<\/p>\n
\u2014 kolumnvektorer, och $inline$(.)^H$inline$ \u00e4r operationen<\/code><\/pre>\n
\n\"Hur
\nDetta kommando sparar \u00e4ndringarna och avslutar. fdisk<\/b>. Oroa dig inte f\u00f6r att l\u00e4sa partitionstabellen misslyckades. N\u00e4sta kommando kommer att hj\u00e4lpa till att \u00e5tg\u00e4rda detta. Det \u00e4r n\u00e4stan klart.<\/i><\/p>\n
9. Vi har l\u00e4mnat fdisk<\/b> och \u00e5terg\u00e5tt till den huvudsakliga Linux -raden. Skriv nu in, som vi blev rekommenderade tidigare:<\/p>\n
sudo partprobe \/dev\/sda<\/code><\/pre>\n
\nOm allt har g\u00e5tt bra, kommer du inte att se n\u00e5got meddelande. Om du inte har programmet partprobe<\/b>, installera det. Det \u00e4r det som partprobe<\/b> uppdaterar partitionstabellerna, vilket g\u00f6r att vi kan ut\u00f6ka partitionen till 50 GB online. L\u00e5t oss forts\u00e4tta.<\/i><\/p>\n
Tips! Du kan installera partprobe<\/b> s\u00e5 h\u00e4r:<\/p>\n
 apt-get install partprobe<\/code><\/pre>\n
<\/i>
\n10. Nu beh\u00f6ver vi \u00e4ndra storleken p\u00e5 partitionen med hj\u00e4lp av programmet resize2fs<\/b>. Det g\u00f6r det online \u2014 \u00e4ven d\u00e5 k\u00f6rde mina skript och skrev till disken. <\/p>\n
Programmet resize2fs<\/b> kommer att skriva om filsystemets metadata. F\u00f6r detta anv\u00e4nder vi f\u00f6ljande kommando:<\/p>\n
sudo resize2fs \/dev\/sda1<\/code><\/pre>\n
\n\"Hur
\nH\u00e4r \u00e4r sda1 namnet p\u00e5 din partition. I de flesta fall \u00e4r detta sda1, men det kan finnas undantag. Var f\u00f6rsiktig. Resultatet \u00e4r att programmet \u00e4ndrade storleken p\u00e5 v\u00e5r partition. Jag ser detta som en framg\u00e5ng.<\/i><\/p>\n
11. L\u00e5t oss nu f\u00f6rs\u00e4kra oss om att partitionens storlek har \u00e4ndrats och att vi nu har 50 GB. F\u00f6r detta upprepar vi det allra f\u00f6rsta kommandot:<\/p>\n
df -h<\/code><\/pre>\n
\n\"Hur
