cannot import 'rpool': one or more devices is currently unavailable

[ericsantos]

I am absurdly beginner who just use proxmox to create 4 or 5 VMs to use in my ISP. Today, my system just stoped and now i'm just stuck at initramfs. I've tried all solutions i found in this forum and no one worked.
I dont have any idea how to proceed if this system just don't start anymore, pls, help me
OBS: to complete, i'm brazilian and not will understand abbreviations or things like this

Is there any more information on the display about the rpool?
How many disk drives did you use for the rpool? Was it one, or two (RAID1), or more (RAIDZ-1)?
Can you see the disk drives in the BIOS when the computer starts?

when i use the command zpool import -f he shows me this

action: The pool cannot be imported due to damage devices or data

i have 2 ssd's raid, i can see them both in the bios and also when i use this code shows me this description about one disk
FAULTED to many errors

Are the 2 ssd's in raid0 (striped, twice the size available) or in raid1 (mirror, everything duplicated, half the size available)?
Can you remove the disk with many errors from the computer? Or check if cables are connected properly?

 

[ericsantos]

they are in raid0. the disk that is giving errors is 2
when i remove the disk with errors, the system stop at grub rescue
about the connections, my computer have 4 slots. i tried to boot with the disk2 in all slots and the same happens

I am sorry, but if there are errors in a raid0, I think you need to reinstall and/or restore from your last backup.
Sometimes the errors are in only a few files, but if the rpool cannot be imported, I think there is nothing you can do to fix it.
Maybe someone else here on the forum is a ZFS-expert and knows if there is anything to be fixed?

omg, this is one of my biggest fears
unfortunately i dont have any backup of all VMs, only of some systems that ran on them

 

[leesteken]

If the VMs are on other disks, you might be able to manually recreate them after a reinstall of Proxmox.
Maybe it is not nice to say, but if you run everything on multiple disks without redundancy and without backups, you run in the most fragile and dangerous way!
Maybe wait a little bit before reinstalling and get a second opinion from someone else on this forum or an expert.
