我在我的一个系统上收到了许多这样的消息:
[ 348.515157] EXT4-fs (vda9): VFS: Can't find ext4 filesystem

磁盘如下所示:
Model: Virtio Block Device (virtblk)
Disk /dev/vda: 6001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 6001GB 6001GB zfs zfs-5514fd574fd36816
9 6001GB 6001GB 8389kB
它是 KVM/Qemu 系统 (Proxmox) 上带有 VirtIO 磁盘的 Ubuntu-VM。它工作正常,但我不明白这里发生了什么。
我怎样才能解决这个问题?谢谢!
这些消息通常是通过
mount
在挂载时尝试猜测文件系统类型来生成的。指定文件系统类型的-t
选项是可选的,如果未指定,mount
将尝试自动确定类型。在您的情况下,某些东西正在挂载或尝试挂载
vda9
而不指定文件系统类型。当您使用 ZFS 并查看分区的大小和位置时,我猜vda9
是 ZFS 在给定整个磁盘时自动创建的备用分区。我不确定为什么有些东西试图安装它,但是您在上面粘贴的消息纯粹是信息性的,可以安全地忽略 - 如果您每天收到数百条消息并且它们堵塞了,我只会担心你的日志文件。
