최근에 SSD를 더 큰 SSD로 교체했습니다. 나는 사용했다클론질라기존 디스크를 새 디스크로 복제합니다. 그 후 나는GParted 라이브기존 파티션의 크기를 조정하려면 스왑 파티션을 디스크 끝으로 밀어넣습니다. 또한 Ubuntu 16.04에서 18.04로 업데이트했습니다.

위의 단계를 성공적으로 마친 후부팅시간이 많이 길어졌습니다. 나는 몇 가지 유사한 스레드(아래 링크)를 발견하고 거기에 제안된 것을 시도했습니다. 그러나 부팅 시간은 디스크 변경 전 수준으로 줄어들지 않았습니다.

내 원본은 다음과 같습니다 /etc/fstab.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=e15b2ef7-c32d-46f5-a3a8-4bdc60285b4e /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=3a0c2581-52f2-4c92-9c4a-09d3f0258c05 none            swap    sw              0       0
/dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0 /mnt/usb-Generic_USB_Flash_Disk-0:0 auto nosuid,nodev,nofail,x-gvfs-show 0 0

이미 파티션을 살펴보며 파티션 UUID을 교체했습니다.swap블키드명령 출력:

/dev/sda1: UUID="e15b2ef7-c32d-46f5-a3a8-4bdc60285b4e" TYPE="ext4" PARTUUID="000d7e8b-01"

/dev/disk/by-id/usb-..나는 또한 이것이 내가 GParted Live를 부팅한 USB 스틱이라고 믿기 때문에 주석을 달았습니다 . 왜 아직도 거기에 정의되어 있는지 모르겠습니다.

'이력서' 파일이 있는 것 같아요

/etc/initramfs-tools/conf.d/resume

더 이상 찾을 수 없는 UUID를 가리킵니다. 스왑 파티션의 올바른 UUID를 가리키도록 해당 파일을 수정하고 다음을 실행할 수 있습니다.

sudo update-initramfs -u

버그 보고서에 대한 다음 링크의 의견 #16 및 #17을 참조하세요.

https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1763611


귀하의 사례와 버그 리포트의 사례에는 차이가 있습니다.

  • 귀하의 경우에는 스왑 파티션을 사용하고 있습니다
  • 버그 보고서의 경우 스왑 파일이 사용됩니다(따라서 가리켜야 하는 스왑 파티션이 없습니다).
