I have converted a large ext4 filesystem to btrfs and by accident deleted an important users home directory. Reading btrfs doc seems to imply that the directory can be recovered without reverting the filesystem to ext4.
First, you should never try converting important data without a backup...
What I've read seems to be telling me to mount the subvolume ext2_saved and then mount the image file residing in that directory. I am VERY new to btrfs and am seeing some troubling output (see below). Here's what I've done and what I'm seeing. Could someone help me with this please? ls -al /ext2_saved total 1699142444 drwxr-xr-x 1 root root 10 Feb 16 06:07 . dr-xr-xr-x. 81 root root 12288 Feb 21 12:51 .. -r-------- 1 root root 1777055391744 Feb 16 06:07 image fc35-bash 5.1 ~# fc35-bash 5.1 ~# fc35-bash 5.1 ~# mount -t ext4 -o loop,ro /ext2_saved/image /ext4 mount: /ext4: can't read superblock on /dev/loop0.
I don't know much about btrfs, but what does "file /ext2_saved/image" say? _______________________________________________ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
