Subject: 12 TB btrfs file system on virtual machine broke again
Date: Sat, 4 Jan 2020 14:07:08 -0300	[thread overview]
Message-ID: <256D0504-6AEE-4A0E-9C62-CDF975FDE32D@icloud.com> (raw)

Hi guys, 

I run again in a problem with my btrfs files system.
I start wondering if this filesystem type is right for my needs.
Could you please help me in recovering my 12TB partition?

What happened? 
-> This time I was just rebooting normally my virtual machine. I discovered during the past days that the system hangs for some seconds so I thought it would be a good idea to reboot my SUSE Linux after 14 days of working. The machine powered off normally but when starting it run into messages like the pasted ones.

I immediately powered off again and started my Arch Linux where I have btrfs-progs version 5.4 installed.
I tried one of the commands that you gave me in the past (restore) and I got following messages:


btrfs-progs-5.4]# ./btrfs restore -l /dev/sdb1
