Dobr\u00fd de\u0148, v\u00e1\u017een\u00ed
\nStalo sa to vo \u0161tvrtok ve\u010der a jeden z na\u0161ich adminov mal zmeni\u0165 ve\u013ekos\u0165 disku na jednom z virtu\u00e1lnych KVM serverov. Mohlo by sa zda\u0165, \u017ee ide o \u00faplne trivi\u00e1lnu \u00falohu, ale m\u00f4\u017ee to vies\u0165 k strate d\u00e1t... A tak\u2026 cel\u00e1 hist\u00f3ria je u\u017e pod katom.
\n<\/a><\/noindex>
\nAko som u\u017e spomenul \u2014 vo \u0161tvrtok ve\u010der (ako vyzeralo, \u017ee d\u00e1\u017e\u010f nebol) jeden z na\u0161ich adminov sa rozhodol dokon\u010di\u0165 dlhodobo napl\u00e1novan\u00fa \u00falohu a zv\u00e4\u010d\u0161i\u0165 ve\u013ekos\u0165 FS vo vn\u00fatri virtu\u00e1lky. KVM<\/a>.<\/p>\n

Predbe\u017ene som u\u017e zv\u00fd\u0161il ve\u013ekos\u0165 samotn\u00e9ho disku z 14 GB na 60 GB a admin potreboval iba zv\u00fd\u0161i\u0165 ve\u013ekos\u0165 FS vo virtu\u00e1lnej ma\u0161ine.<\/p>\n

Pribli\u017ene o polnoci admin posiela spr\u00e1vu \u2014 kde sa p\u00fdta, \u010di m\u00e1 by\u0165 oddiel roz\u0161\u00edren\u00fd alebo prim\u00e1rny... V odpovedi som mu nap\u00edsal, \u017ee to treba urobi\u0165 tak, ako to bolo predt\u00fdm na samotnej virtu\u00e1lke. <\/p>\n

\u010cas plynul\u2026 a admin hl\u00e1si, \u017ee sa mu objavili chyby, \u017ee roz\u0161\u00edri\u0165 oddiel sa nepodarilo\u2026 a prestal sa montova\u0165\u2026 na hodin\u00e1ch u\u017e bolo 2 r\u00e1no\u2026<\/p>\n

Nap\u00edsal som mu, aby u\u017e ni\u010d nerobil a nechal virtu\u00e1lku na pokoji a s\u00e1m som sa pustil do vytv\u00e1rania k\u00f3pie obrazu disku VM \u2014 nazval som ho vmname_bad.<\/p>\n

V\u0161etko sa e\u0161te komplikovalo t\u00fdm, \u017ee admin nevytvoril snapshot a nekop\u00edroval rozlo\u017eenie pred svojimi akciami... S touto inform\u00e1ciou by sa dalo vr\u00e1ti\u0165 sp\u00e4\u0165 a sk\u00fasi\u0165 to znova.<\/p>\n

R\u00e1no, s \u010dist\u00fdmi my\u0161lienkami, zdvihnem virtu\u00e1lku s rovnak\u00fdm OS (Debian 9) a pripoj\u00edm disk. cez fdisk vid\u00edm tento disk u\u017e roz\u0161\u00edren\u00fd na 60 GB a oddiel... ktor\u00fd je vlastne trochu po\u0161koden\u00fd. <\/p>\n

Sna\u017e\u00edm sa na z\u00e1klade screenshotov, ktor\u00e9 admin poskytol \u2014 n\u00e1js\u0165 predch\u00e1dzaj\u00face rozlo\u017eenie, ale bohu\u017eia\u013e m\u00e1rne. Sna\u017e\u00edm sa cez fdisk naladi\u0165 hodnoty, ale v\u0161etky pokusy sa uk\u00e1zali ako ne\u00faspe\u0161n\u00e9.<\/p>\n

Ke\u010f mi fdisk nem\u00f4\u017ee pom\u00f4c\u0165... vol\u00e1m na pomoc parted. Na\u010d\u00edtame parted \u2014 odstr\u00e1nim star\u00fd oddiel rm 2 a poznaj\u00fac pribli\u017en\u00e9 hodnoty rozdelenia rob\u00edm rescue \u2014 uv\u00e1dzam po\u010diato\u010dn\u00fa a kone\u010dn\u00fa hodnotu, kde m\u00f4\u017ee by\u0165 priate\u013e. Min\u00fatov\u00e9 \u010dakanie a parted n\u00e1jde oddiel a pon\u00faka zavies\u0165 o \u0148om inform\u00e1cie do syst\u00e9mu \u2014 s\u00fahlasil som a vy\u0161iel som z parted.<\/p>\n

Montujem oddiel \u2014 v\u0161etko OK. S\u00fabory s\u00fa na mieste, v\u0161etko je v poriadku, ale ve\u013ekos\u0165 e\u0161te star\u00e1 14 GB. Odmontoval som \/dev\/sdd1 a rob\u00edm resize2fs \/dev\/sdd1, potom e2fsck \/dev\/sdd1 a montujem znova a vid\u00edm u\u017e roz\u0161\u00edren\u00fd oddiel so v\u0161etk\u00fdmi s\u00fabormi a celkom \u017eiv\u00fd. <\/p>\n

V\u0161etko sa skon\u010dilo dobre pre m\u0148a aj pre admina.
