- 檢查其中一個受影響的資料分割區的 cpbackup 記錄檔,發現一則訊息,指出 data06 和 data07 的 cpbackup 記錄中的 diskfull 導致伺服器為唯讀

- 執行 fs-perc 會顯示 data01 與其他磁碟分割有很大的差異:
avmaint nodelist |grep -i "fs-perc" fs-percent-full="37.0" fs-percent-full="8.8" fs-percent-full="8.7" fs-percent-full="8.7" fs-percent-full="8.8" fs-percent-full="8.7" fs-percent-full="8.7" - 執行 df -h 顯示 data01 的大小比其他分割區小,但已滿 37%,而其他則為 9%
df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 16G 5.0G 10G 34% / udev 18G 184K 18G 1% /dev tmpfs 18G 0 18G 0% /dev/shm /dev/sda1 1011M 91M 869M 10% /boot /dev/sda6 7.6G 287M 6.9G 4% /var /dev/sda8 62G 14G 45G 25% /space /dev/sdb1 250G 93G 158G 37% /data01 /dev/sdc1 1.0T 90G 934G 9% /data02 /dev/sdd1 1.0T 89G 935G 9% /data03 /dev/sde1 1.0T 90G 935G 9% /data04 /dev/sdf1 1.0T 91G 934G 9% /data05 /dev/sdg1 1.0T 90G 935G 9% /data06 /dev/sdh1 1.0T 90G 935G 9% /data07
Cause
磁碟分割 /data01 為 250G,而其他為 1 TB,因此其使用率高於其他磁碟分割。我們不支援在同一 AVE 中具有不同的數據分區大小。
由於這是 4TB AVE,因此應有六個數據分區(每個 1 TB);資料來源: https://www.delltechnologies.com/asset/en-us/products/data-protection/technical-support/docu91853.pdf (「AVE 虛擬磁碟需求」,第 17 頁)
同一頁面中有一個註釋:「
由於 AVE .ova 安裝會將三個 250 GB 的儲存分區與操作系統磁碟一起創建,因此安裝時需要大約 900 GB 的可用磁碟空間。但是,AVE .ovf 安裝不會在安裝期間創建存儲分區。因此,安裝時只需要足夠的磁碟空間供操作系統磁碟使用,並且可以在其他數據存儲上創建後續存儲分區”
由於此 AVE 有七個分割區 (其中一個為 250 GB,其餘為 1 TB),而非 1 TB 中的 6 個),因此 AVE 部署將會錯誤。
Resolution
在此情況下,客戶必須部署新的 4 TB AVE (含 6x1TB 資料分割區,無 250GB 分割區)。然後將所有資料複寫到新系統
Additional Information
新的部署將由當地團隊和專業服務部門負責。
