'attempt to read or write outside of disk 'hd0' ’after the power cut

se flag

My machine is Dell PowerEdge730, Ubuntu 20.04.

The power is out. I try to reboot it after power return.

The grub interface appears first. In the past, I always reboot the computer with these commands and work well.

linux /boot/vmlinuz-5.11.0-41-generic ro root=/dev/sda3
initrd /boot/initrd.img-5.11.0-41-generic
boot

But now after the execution of the second line of command, attempt to read or write outside of disk 'hd0' appear.

I want to know how to reboot it correctly.

The commands I try to get the computer's information as the following images

5.11 is **not** a *supported* kernel of Ubuntu 20.04 LTS, so either you've a ~year behind no upgrades & security fixes, or something is very wrong. I'd suggest booting *live* media & perform checks firstly on your drive health, secondly on the file-system - if errors are detected & fixed with the *fs* I'd expect normal boot after that, but the 5.11 kernel shows a security concern if your machine is online. Check what you're using (5.4 is the GA kernel of 20.04, 5.15 is the HWE kernel for 20.04)

Can you be more specific? What should I do when I booting by live media?What's the fs?I'm sorry about I don't know ubuntu very well.And I really haven't updated it for a long time.

*fs* is the file-system I referred to; ie. you should be checking drive health (*out of good habit on any issue such as you're reporting; hopefully you have the system perform daily checks anyway - but given you're a year+ behind on security fixes I suspect you're not*), then file-system checks. If *fs* checks detect issues as I mentioned they'll be fixed & you'll be able to boot normally as I stated. That machine should be kept offline given how far behind on security fixes it is. (*other than commands I didn't mention; this is generic IT knowledge & not Ubuntu specific; NTFS is a fs*)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
