Ungayishintsha kanjani i-UUID yokwahlukanisa ku-Linux

La I-UUID (Isazisi Esiyingqayizivele Somhlaba Wonke) isihlonzi esiyingqayizivele semvelo esikhomba ngokuhlukile ukwahlukaniswa kohlelo lwefayela noma i-FS. Yikhodi ejwayelekile esetshenziswe ku-Linux ongayibona ku / etc / fstab, ngokwesibonelo, futhi yakhiwe ngamabhayithi ayi-16, okungukuthi, ama-bits angama-128. Ngakho-ke, inezinhlamvu ezingama-36 zezinombolo ezihlukaniswe ngamaqembu amahlanu ngefomethi: 8-4-4-4-12. Lokho kunikeza amakhodi amaningi futhi ithuba lamakhodi amabili afanayo liphansi impela.

Isibonelo, i-UUID ejwayelekile ingaba yi-6700b9562-d30b-5d52-82bc-655787665500. Yebo, uma uzithola uphatha uhlelo lwe-GNU / Linux futhi ufuna ukuliguqula nganoma yisiphi isizathu, manje uzobona ukuthi kanjani ungayiguqula kalula. Kepha ngaphambi kwalokho, ngizokukhombisa ukuthi ungawabona kanjani ama-UUID ezingxenye zakho akhona ku-distro yakho ngokwenza noma imuphi umyalo olandelayo:

cat /etc/fstab
sudo blkid|grep UUID

Kepha uma ufuna buka i-UUID yokwahlukanisa okuthile noma idivayisi, ungakwenza kanjena:

sudo blkid | grep sdd4

Lapho usuwazi ama-UUID, ungayishintsha ngendlela elula ngomyalo olandelayo, ucabanga ukuthi lesi yisigaba ofuna ukusishintsha i-UUID:

umount /dev/sdd4
tune2fs /dev/sdd4 -U random

Njengoba ubona, kufanele qala wehlise ukwahlukanisa ufuna ukuguqula, bese usebenzisa umyalo olandelayo ukuze ikhiqize ngokungahleliwe i-UUID entsha bese ubheka i-UUID yalolo hlukaniso futhi ukuze uqinisekise ukuthi isishintshile.

Ungakhohlwa ukuguqula i-UUID enkambini ehambisanayo ye / etc / fstab noma. uma lokho kuhlukaniswa kukuleli fayela ukuze lifakwe ngokuzenzekelayo nge-boot system. Ngaphandle kwalokho kuzoba nezinkinga zokungaboni i-UUID. Ungakopisha i-UUID ekhonjisiwe bese uyinamathisela kunkambu efanele ye-fstab ukumiselela endala usebenzisa umhleli wombhalo wakho owuthandayo ...
