![CentOS 7:重新启动后,zfs 模块将无法加载,没有 /dev/zfs](https://linux22.com/image/200865/CentOS%207%EF%BC%9A%E9%87%8D%E6%96%B0%E5%90%AF%E5%8A%A8%E5%90%8E%EF%BC%8Czfs%20%E6%A8%A1%E5%9D%97%E5%B0%86%E6%97%A0%E6%B3%95%E5%8A%A0%E8%BD%BD%EF%BC%8C%E6%B2%A1%E6%9C%89%20%2Fdev%2Fzfs.png)
959 天后,CentOS 7 系统需要重新启动,该系统在过去几年中一直完美地使用 ZFS。yum update
那段时间我每个月跑步一次。
重启系统显然无法加载其 ZFS 模块,如下所示
# zpool list
/dev/zfs and /proc/self/mounts are required.
Try running 'udevadm trigger' and 'mount -t proc proc /proc' as root.
# modprobe zfs
modprobe: FATAL: Module zfs not found.
# uname -a
Linux foo 3.10.0-1160.49.1.el7.x86_64 #1 SMP Tue Nov 30 15:51:32 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
# yum install zfs zfs-kmod
Package zfs-0.7.13-1.el7_6.x86_64 already installed and latest version
Package kmod-zfs-0.7.13-1.el7_6.x86_64 already installed and latest version
Nothing to do
/proc
已安装并且udevadm trigger
没有任何效果。/dev/zfs
不存在。 Grepping dmesg for ZFS(不区分大小写)为空。手动加载模块说
# modprobe zfs
modprobe: FATAL: Module zfs not found.
我很困惑。我怎样才能让 ZFS 再次运行?
编辑
一个问题是我的仓库/etc/yum.repos.d/zfs.repo
仍然是 7.6,而是/etc/yum.repos.d/zfs.repo.rpmnew
7.9。我保存了旧的 zfs.repo 并将 7.9 的 zfs.repo 复制到zfs.repo
.然后再次按照 kABI 的说明进行操作。现在我得到了这个:
# yum install zfs

如何解决依赖问题?
答案1
959天没有重启?哇。我假设您没有使用kexec
,这意味着您已经第一次启动了新内核。问题是您安装的 ZFS 模块是为不同的内核构建的,因此您现在无法加载它。
您的选择:
- 尝试使用
weak-modules
skript(weak-modules --add-kernel --no-initramfs
如果 initramfs 中不需要 ZFS)。如果 kABI 没有更改,它会将模块符号链接到新/lib/module
目录,以使其可与新内核一起使用。 (如果这确实是您第一次使用新内核,则可能存在 kABI 更改。) - 如果上述方法不起作用,您可以尝试重新安装软件包。 OpenZFS提到这个作为在 CentOS 小版本之间升级时的必要步骤。
- 您需要先删除现有的
zfs
,spl
和包。kmod-zfs
yum remove zfs spl kmod-zfs
- 安装 7.9 的最新存储库OpenZFS。
yum install https://zfsonlinux.org/epel/zfs-release.el7_9.noarch.rpm rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux
- 从新添加的存储库
zfs
安装。kmod-zfs
- 您需要先删除现有的
- 您还可以尝试安装数据管理系统模块(将在内核更新后自动重建)而不是您现在使用的 kmod 软件包。
