내 루트 LV를 새 SSD의 새 VG로 옮기려고 하는데 정말 미칠 것 같습니다. 나는 rsync를 사용하여 이를 달성했다고 생각했지만 이제 grub은 /dev/vg_ssd/lv_root에서 새 부팅 옵션 등록을 거부합니다. Linux에는 AIX처럼 cplv 또는 lvmove가 없는 이유는 무엇입니까?
vg_dopey/lv00 대신 vg_ssd/root를 사용하여 /에 마운트하고 싶습니다. /boot는 독립적입니다. 그럽2/FC17. Linux dopey 3.6.2-4.fc17.x86_64 #1 SMP Wed Oct 17 02:43:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

답변1
pvmoveVG 내의 LV를 기존 PV에서 다른 PV로 이동합니다.
이렇게 하면 문제가 해결될 수도 있습니다...
답변2
fstab이 손상된 것 같습니다. 수정하고 /etc/fstab설치 루트에 대한 줄을 새 줄(아마도 UUID=XXX)로 변경하세요.
모든 uuid를 찾으려면 blkid루트로 실행하십시오.
grub.cfg가 오래된 경우 grub-mkconfig -o /boot/grub/grub.cfggrub.cfg 재생성을 사용하세요.
편집하다
grub이 루트 장치를 검색할 때 현재 설치된 장치를 루트 장치로 간주합니다. grub.cfg를 수동으로 수정하고 SSD에서 부팅한 후 grub-mkconfig다시 실행 해야 합니다.
