排除IOS XE SD-WAN升级故障：空间不足

简介

本文档介绍在Cisco IOS® XE SD-WAN升级因存储容量不足而失败时诊断和解决问题的流程。

先决条件

广域网边缘路由器

要求

Cisco 建议您了解以下主题：

• 思科软件定义广域网(SD-WAN)
• Cisco IOS® XE命令行界面(CLI)

对于Cisco IOS XE SD-WAN升级信息使用CLI或vManage升级Cisco IOS XE SD-WAN路由器

使用的组件

本文档基于以下软件和硬件版本：

• 路由器c1111-8P
• 软件版本17.3.2
• 软件版本17.3.4
• 处于控制器模式的路由器

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。

条件

1. 无法将路由器型号c1111-8p升级到17.3以及17.5之前的其它版本。

2. 请考虑以下错误：

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. 升级失败，如下图所示：

4. 只安装了一个版本。使用命令 show sdwan software 进行验证。

示例

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

故障排除

1.使用以下命令删除不必要的文件：

delete /force /recursive bootflash:/<directory>/<file ext>

您可以删除下一个文件列表。它们是内部日志，用于进行故障排除。

注意：如果确定没有其他调查正在进行，请删除这些调查。

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

示例

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

警告：请勿删除这些文件。它们是路由器功能的基本文件。

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

2. 重新启动有助于释放bootflash内存，如示例所示。

警告：重新启动期间控制层面和数据层面会发生摆动。 

*** Before Reboot *** 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 >>> Here edge# *** Rebooting edge edge#reload Proceed with reload?

解决方法

如果之前的操作不起作用，请应用以下步骤升级路由器c1111-8p。 

问题 1

如果升级问题与此错误Not enough space under bootflash有关，请参阅下一说明。

步骤1: 启用IOx。

Config-transaction
iox
commit
end

第二步：运行下一个命令，将IOx日志从bootflash移到闪存。

app-hosting move system techsupport to flash:

第三步： 禁用IOx。

Config-transaction
no iox
commit
end

示例

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#

第四步： 继续升级。

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 <IOS version>

提示：对于通过vManage升级SD-WAN cEdge路由器，请使用CLI或vManage

问题 2

如果升级问题与此错误“SD-WAN安装程序文件系统中空间不足”有关，请参阅以下说明。

步骤1: 登录到shell。 

有关详细信息，请参阅。

第二步： 转到.sdwaninstaller/images目录。使用Linux命令查找和删除旧文件。

cd /bootflash/.sdwaninstaller/images
ls -l
rm -rf <old file>

第三步： 使用Linux命令退出外壳。

exit

第 4 步： 继续升级。

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 <IOS version>

提示：对于通过vManage升级SD-WAN cEdge路由器，请使用CLI或vManage

警告


通过vManage GUI升级期间可能存在的问题：

• 空间不足

修复：验证bootflash并删除所有未使用的映像。您可以使用命令通过CLI文件删除所有软件包 # delete bootflash:*17.03.01*.

此命令将删除名为17.03.01的所有文件。

Edge#delete bootflash:*17.03.01* Delete filename [*17.03.01*]? Delete bootflash:/isr4300-firmware_dreamliner.17.03.01a.SPA.pkg?

您也可以从USB驱动器启动，从Bootflash删除所有映像，将bin文件复制到Bootflash，然后重新启动。

• 路由器中已存在映像

您可以通过vManage GUI或CLI使用命令show sdwan software验证版本是否已存在。

修复：通过vManage GUI或使用request platform software sdwan software remove <Name>命令删除未使用的映像。

• 路由器中有三个以上的映像

您可以通过vManage GUI或CLI使用命令show sdwan software验证版本是否已存在。

修复：通过vManage GUI或使用 request platform software sdwan software remove <Name>命令删除未使用的映像。
