排除IOS XE SD-WAN升級故障：空間不足

簡介

本文檔介紹當因儲存容量不足而導致Cisco IOS® XE SD-WAN升級失敗時診斷和解決該問題的過程。

必要條件

WAN邊緣路由器

需求

思科建議您瞭解以下主題：

• 思科軟體定義廣域網路(SD-WAN)
• Cisco IOS® XE命令列介面(CLI)

針對Cisco IOS XE SD-WAN升級資訊使用CLI或vManage升級Cisco IOS XE SD-WAN路由器

採用元件

本檔案是根據以下軟體和硬體版本所編制：

• 路由器c1111-8P
• 軟體版本17.3.2
• 軟體版本17.3.4
• 處於控制器模式的路由器

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

狀況

1.無法將路由器型號c111-8p升級到17.3和17.5之前的其它版本。

2.請考慮以下錯誤：

Not enough space under bootflash for image download and package expansion on image installation. Required space: 1207202432 Available space: 659275776. Image installation failed.
Not enough space in SD-WAN installer filesystem. Please remove one of the installed images and try again. SD-WAN installer filesystem size - 396672 Kilobytes, Available space - 196986 Kilobytes, Required space - 243602 Kilobytes.

3.升級失敗，如下圖所示：

影象1

影象2

4.只安裝了一個版本。使用命令 show sdwan software 進行驗證。

範例

edge#show sdwan software 
VERSION           ACTIVE  DEFAULT  PREVIOUS  CONFIRMED  TIMESTAMP                  
-----------------------------------------------------------------------------------
17.03.04a.0.5574  true    true     false     user       2021-10-22T23:00:30-00:00  

Total Space:387M Used Space:191M Available Space:192M

疑難排解

1.使用以下命令刪除不必要的檔案：

delete /force /recursive bootflash://

您可以刪除下一個檔案清單。這些是出於故障排除目的而建立的內部日誌。

注意：如果確定沒有其他調查正在進行中，請刪除這些調查。

bootflash:/vmanage-admin/*.tar.gz
bootflash:/core/*.core.gz
bootflash:/core/*.tar.gz
bootflash:/syslog/*
bootflash:/tracelogs/*
bootflash:/crashinfo_*

範例

delete /force /recursive bootflash:/tracelog/*
delete /force /recursive bootflash:/ vmanage-admin/*.tar.gz

警告：請勿刪除這些檔案。它們是路由器功能的基本檔案。

bootflash:/.sdwaninstaller
bootflash:/.sdwaninstallerfs
bootflash:/.cdb_backup folder
bootflash:/sdwan folder
bootflash:/*pkg
bootflash:/*.conf.

2. Reboot幫助釋放bootflash記憶體，如示例所示。

注意：控制平面和資料平面在重新引導時擺動。

解決方法

如果之前的操作無法升級路由器c1111-8p，請應用後續步驟。 

問題1

如果升級問題與以下錯誤相關：bootflash下的空間不足，請參考下一個說明。

步驟1. 啟用IOx。

Config-transaction
iox
commit
end

步驟2.運行下一個命令，將IOx日誌從bootflash移動到快閃記憶體。

app-hosting move system techsupport to flash:

步驟3.禁用IOx。

Config-transaction
no iox
commit
end

範例

Before IOx enabling
edge#dir
Directory of bootflash:/
<snipped>
2908606464 bytes total (646643712 bytes free)
edge#                

After IOx disabling
edge#dir
Directory of bootflash:/
<snipped>
2908606464 bytes total (1671614464 bytes free)
edge#

步驟4.繼續升級。

request platform software sdwan software install bootflash:<version.bin>
request platform software sdwan software activate <IOS version>
request platform software sdwan software upgrade-confirm
request platform software sdwan software set-default 

提示：用於通過vManage升級SD-WAN cEdge路由器（使用CLI或vManage）進行升級

問題2

如果升級問題與以下錯誤「SD-WAN安裝程式檔案系統中空間不足」有關，請參閱以下說明。

步驟1.登入shell。 

有關詳細資訊，請參閱。

步驟2.轉到.sdwaninstaller/images目錄。使用Linux命令查詢並刪除舊檔案。

cd /bootflash/.sdwaninstaller/images
ls -l
rm -rf 

步驟3.使用Linux命令從外殼中退出。

exit

步驟4.繼續升級。

request platform software sdwan software install bootflash:
request platform software sdwan software activate 
request platform software sdwan software upgrade-confirm
request platform software sdwan software set-default 

提示：用於通過vManage升級SD-WAN cEdge路由器（使用CLI或vManage）進行升級

警告

通過vManage GUI升級期間可能存在的問題：

• 空間不足

修正:驗證bootflash並刪除所有未使用的映像。您可以使用命令通過CLI檔案刪除所有軟體包 # delete bootflash:*17.03.01*.

此命令將刪除名為17.03.01的所有檔案。

Edge#delete bootflash:*17.03.01*

Delete bootflash:/isr4300-firmware_sm_10g.17.03.01a.SPA.pkg? [confirm]

您還可以從USB驅動器啟動、從bootflash刪除所有映像、將bin檔案複製到bootflash並重新啟動。

附註：如果路由器處於控制器模式，則所有來自與資料包相關的IOS-XE命令均無法正常工作。

附註：通過CLI更改引導變數在控制器模式下也被禁用。您可以將裝置移至自主模式、升級，然後將其移回控制器模式。

• 路由器中已存在該映像

您可以使用命令show sdwan software通過vManage GUI或CLI驗證版本是否已存在。

修正:通過vManage GUI或使用命令request platform software sdwan software remove 刪除未使用的映像。

• 路由器中有三個以上的映像

您可以使用show sdwan software 指令，透過vManage GUI或CLI驗證版本是否已存在。

修正:通過vManage GUI或使用命令刪除未使用的映像 request platform software sdwan software remove 。
