【在 ttaudi 的大作中提到: 】
: 不是zfs root，debian安装后会装一些zfs服务，会在开机的时候自动把zfs import。我就是卡在这个步骤了
: U盘试过了，也会卡死在import命令上，然后后台不停的打印
: :你这是用zfs root？先用u盘起来看看能不能import吧。

根本就没有看到有关zfs pool的信息呀。

现在基本可以确定是import的时候卡住了。

我按你说的，用另外一个系统起来，手动运行import命令，接着就卡死在这里。

root@bookworm: ~ # zpool import -f ocean

kernel panic了，未见得是zfs本身的问题，有可能是kernel版本或者
zfs软件的问题，换个新点的试试呗

所以你现在已经读写数据了？

只能看到一部分数据，就是有的dataset可以读到数据，有的不能，偏偏是存数据最多的dataset看不到数据。

最新进展：

用zpool import -o readonly=on ocean 可以正常打开 zfs ，并能看到全部数据。
但是如果直接import，就会提示panic，然后就命令就死在import了，用kill -9都杀不掉，zfs的数据也只能看到一部分，不能看到全部。
```
root@srv18: / # zpool import ocean

趁能看到数据先备份数据？说不定是硬盘坏了

多谢提醒，在备份数据了，备份完成再继续搞。
