Dokumen ini menjelaskan masalah umum yang mungkin Anda alami saat mengimpor image ke Compute Engine dan saat mengekspor image ke Cloud Storage.
Mendiagnosis masalah impor dan ekspor image
Diagnosis penyebab masalah impor atau ekspor image dengan meninjau log Cloud Build dan output port serial dari VM sementara (atau worker VM).
Meninjau log Cloud Build
Alat impor image menggunakan Cloud Build API untuk mengimpor dan mengekspor image.
Tinjau log Cloud Build untuk mendapatkan status proses yang sedang berjalan.
Untuk melihat log Cloud Build, lakukan salah satu langkah berikut:
Jika Anda mengimpor atau mengekspor gambar menggunakan konsol Google Cloud , lihat log di halaman Images di konsol Google Cloud , di tab Image import history atau Image export history.
Klik ID Cloud Build untuk melihat log.
Jika mengimpor atau mengekspor image menggunakan Google Cloud CLI, Anda dapat melihat lokasi log Cloud Build di output standar setelah menjalankan prosesnya.
Meninjau output port serial
Meninjau output port serial pada worker VM yang dibuat selama proses impor atau ekspor image mungkin berguna untuk memecahkan masalah terkait entity tingkat sistem. Untuk informasi selengkapnya tentang log ini, lihat Melihat output port serial.
Error yang biasa terjadi
Berikut adalah contoh error umum yang mungkin Anda alami saat mengimpor atau mengekspor image.
Error ExportFailed saat mengekspor image yang lebih besar dari 2 TB
Ukuran maksimum untuk image dalam format vmdk, vpc, dan vhd dibatasi hingga 2 TB. Oleh karena itu, saat mengekspor image yang lebih besar dari 2 TB dalam format tersebut, Anda mungkin akan melihat pesan error yang mirip dengan pesan berikut ini dalam log:
Pesan error:
[image -export]: 2022 - 01 - 27T16: 08: 24Z Error running workflow: step
"image-export-export-disk" run error: step "wait-for-inst-image-export-export-disk"
run error: WaitForInstancesSignal FailureMatch found for
"WORKER_VM_NAME--SUFFIX":
"ExportFailed: Failed to export disk source to DESTINATION_URI"
Penyelesaian:
Untuk mengatasi masalah ini, tentukan format image sebagai vdi, vhdx, atau qcow2 dan tetapkan nilai --timeout sebagai 24h saat Anda menjalankan perintah gcloud compute images export.

For more information about these logs,\nsee [Viewing serial port output](/compute/docs/troubleshooting/viewing-serial-port-output).\n\nCommon errors\n-------------\n\nThe following are examples of common errors you might encounter when you import\nor export images.\n\n### ExportFailed error when exporting images larger than 2 TB\n\nThe maximum size for images in `vmdk`, `vpc`, and `vhd` formats is limited to\n2 TB. Therefore, when you export images larger than 2 TB in these formats, you\nmight see an error message similar to the following in the log:\n\n**Error message**: \n\n```\n[image -export]: 2022 - 01 - 27T16: 08: 24Z Error running workflow: step\n\"image-export-export-disk\" run error: step \"wait-for-inst-image-export-export-disk\"\nrun error: WaitForInstancesSignal FailureMatch found for\n\"WORKER_VM_NAME--SUFFIX\":\n\"ExportFailed: Failed to export disk source to DESTINATION_URI\"\n```\n\n**Resolution**:\n\nTo resolve this issue, specify the image format as `vdi`, `vhdx`, or `qcow2` and\nset the `--timeout` value as `24h` when you run the\n[`gcloud compute images export` command](/sdk/gcloud/reference/compute/images/export).\n\nIf the issue persists, contact [Google Cloud Support](/support) for\nassistance."]]
