grub rescue

[TechLineX]

Hello,

since I rebooted the server a couple hours ago, I can't boot the server normally. I get every time in the grub rescue mode.

No such device.

Booting with an proxmox iso in rescue boot works without any problems.

For ZFS rpool problems:

Type: /sbin/zpool import -N rpool(enter) exit(enter)

I had to add rootdelay=20 in my /etc/default/zfs to the line that starts with 'linux'..., then run update-grub on a recent hardware change to a Dell T630 PERC H330.

See this thread.

But it seem to be not the same error, or not?
What means rootdelay?

I hadn't this problem in the past. What does the command /sbin/zpool import -N rpool(enter) exit(enter) effect?

Regards

I believe it gives the driver/SAS controller more time to initialize. All I know is with a little more pause my ZFS rpool mounts on boot now.

Booting ends in grub rescue
Booting with the iso > resuce boot is working without any problem

I would get something like that when other mount points in my /etc/fstab changed. Not sure if that will help in your situation.

/etc/fstab

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/zvol/rpool/swap none swap sw 0 0
proc /proc proc defaults 0 0

 

[mram]

Nope. That's a default looking fstab file.

 

[TechLineX]

Yep. Would it be a way to reinstall grub?

No more ideas? I Can only Reboot the Host using the Installation ISO > rescue boot

Do you do apt-get upgrade before reboot? If not then why you reboot (maybe replace some adapter) ?
