I/O error in filesystem ("sdb1") meta-data dev sdb1 block 0x54f839cff

English Install/Boot/Login
#1

After a reboot of the system, Suse cannot mount “sdb1”.

This messages comes from dmesg:
attempt to access beyond end of device
sdb1: rw=0, want=22808861952, limit=1334025547
I/O error in filesystem (“sdb1”) meta-data dev sdb1 block 0x54f839cff (“xfs_read_buf”) error 5 buf count 512
XFS: size check 2 failed

what can be wrong ?

When you id not do any special actions (partitioning?) before the shutdown before this boot, I guess that the disk is gone.

I would suggest to make backups of all the other partitions on the same disk asap.

It was just a normal reboot. Nothing was done. It is just one partition on sdb. and it is11 TB.

When i type : parted /dev/sdb print
Disk geometry for /dev/sdb: 0kB - 12TB
Disk label type: msdos
Number Start End Size Type File system Flags
1 32kB 683GB 683GB primary xfs type=83

I think that is wise advice. I guess another possibility is an XFS bug
or some other minor corruption, so it might be worth asking about the
symptoms on the XFS list and running the repair tool. I’m not expert
enough to know the correct invocation, sorry. Details of the list is at

When you want to show how the disk is partitioned, please use

fdisk -l /dev/sdb

And when you want to show this (or any other) computer text, please use CODE tags aound it: Posting in Code Tags - A Guide

You also could try to check/repair the file system with

fsck /dev/sdb1

But I doubt that this works when the partition itself is not correct.

EDIT:
I did not see dhj-novell’s advise, but trying to find out about XFS problems seems like a good advice to me.
