Przegl\u0105daj\u0105c sobie maszyny w Zabbixie zauwa\u017cy\u0142em, ze jedna z maszyn wyrzuci\u0142a alert o ko\u0144cz\u0105cym si\u0119 miejscu na dysku. Maszyna jest wirtualizowana wi\u0119c nie jest wielkim problemem rozszerzanie dysku wirtualnej maszynie na hyperwizorze ale trzrezba tez poinformowa\u0107 o tym sam system operacyjny. S\u0105 dwie metody: jedna poprzez wy\u0142\u0105czenie wirtualnej maszyny, uruchomienie z ISO jakiego\u015b Linuxa Live i zmodyfikowanie partycji przy u\u017cyciu np. GParda. Druga metoda jest operacj\u0105 na dzia\u0142aj\u0105cym systemie. I t\u0119 metod\u0119 wybra\u0142em.<\/p>\n\n\n\n

Maszyna wirtualna pierwotnie mia\u0142a ustawiony dysk na 50G i mia\u0142em nadziej\u0119, ze na troch\u0119 starczy. Jak si\u0119 okaza\u0142o po roku miejsca zbrak\u0142o. No to do dzie\u0142a… Najpierw zmieni\u0142em rozmiar dysku edytuj\u0105c w\u0142a\u015bciwo\u015bci dysku maszyny wirtualnej, nast\u0119pnie zalogowa\u0142em si\u0119 do systemu. Gdzie wykona\u0142em nast\u0119puj\u0105ce polecenia: <\/p>\n\n\n\n

Najpierw sprawdzi\u0142em czy faktycznie miejsce na dysku jest ograniczone
rogmar@domoticz:~$ sudo df -h
[sudo] password for rogmar:

Nast\u0119pnie sprawdzi\u0142em czy faktycznie w VM rozszerzy\u0142em dysk. <\/p>\n\n\n\n

Kolejn\u0105 rzecza jest ustalenie numeru partycji w programie parted.
rogmar@domoticz:~$ sudo parted

No to do dzie\u0142a! (w sumie nie musia\u0142em wychodzi\u0107 z parted ale s\u0142abo by to wygl\u0105da\u0142o w tek\u015bcie wi\u0119c wyszed\u0142em \ud83d\ude09

System ma skonfigurowany LVM wi\u0119c jemu te\u017c trzeba „powiedzie\u0107” o zmianach.
rogmar@domoticz:~$ sudo pvresize \/dev\/sda3
Physical volume „\/dev\/sda3” changed
1 physical volume(s) resized \/ 0 physical volume(s) not resized<\/p>\n\n\n\n

Kolej na rozszerzenie partycji LVM
rogmar@domoticz:~$ sudo lvextend -l +100%FREE \/dev\/mapper\/ubuntu–vg-ubuntu–lv
Size of logical volume ubuntu-vg\/ubuntu-lv changed from 4.00 GiB (1024 extents) to <99.00 GiB (25343 extents).

Ughhhh jak zwykle zapominam, \u017ce w Ubuntu trzeba dzia\u0142ac z sudo…<\/p>\n\n\n\n


rogmar@domoticz:~$ resize2fs \/dev\/mapper\/ubuntu–vg-ubuntu–lv

Poprawiam polecenie

Jeszcze tylko sprawdzi\u0107 czy faktycznie dzia\u0142ania sko\u0144czy\u0142y si\u0119 sukcesem.<\/p>\n\n\n\n

rogmar@domoticz:~$ sudo df -h

Teraz zobaczmy czy pacjent dalej \u017cyje \ud83d\ude09<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Uwierz\u0119 jak wstanie po reboocie \ud83d\ude09 <\/p>\n\n\n\n
