However, recovery of the filesystem in place may not be possible, and as Chris indicated, you almost certainly want to avoid making any changes to the data on the disk (filesystems or files) until your data is recovered. That means copying data off of that disk to another disk. You probably want to look at photorec and testdisk. Run them from a bootable live USB installation to see if they can find your files. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org

Be careful when reduc‐ ing a logical volume's size, because data in the reduced part is lost!!! You should therefore ensure that any filesystem on the volume is shrunk first so that the extents that are to be removed are not in use. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org

If you really ran mke2fs, the fs probably not recoverable, if additionally you mounted it, I don't see how it's recoverable (mounting causes inode initialization which will write over large areas of the volume, due to the resize, it will be writing on top of both data and old metadata - the whole thing will be a mess). Anyway, I think this is a case for debugfs, but you're probably best off asking about serious ext4 related problems on the ext4 list. The more you keep making modifications without actually knowing what you're doing, the greater the chance of total data loss. > > > Now, I know data is there and I need to recover it. > > I found a recovery point from 2014 in /etc/ LVM/archive. However, my problem > is when I try to recover with > > Pvcreate --uuid --restorefile file /dev/sda8 Doesn't seem related at all. In your steps you've only done a resize of the fs volume. You hadn't yet resized the LV, and in any case that's not the problem if you can mount home successfully and it's just empty.

And it's also not mounted in your df report. Can you report the output from the command lvs? Did you want to preserve the existing /home on /dev/sda perhaps? Manual Partitioning does allow you to find a previous installation's /home, and you can choose to keep it by setting it as a mount point at /home. And then deleting everything else. But that would have gotten you what you wanted. Yet you're reporting you don't have the layout you want. So there definitely was a miscommunication between user and installer. It's actually quite a valid point, that the Guided path doesn't have a mechanism at all to preserve an existing /home. And yet a separate /home partition (or LV) is the default installation layout for Fedora. Considering all of the mind boggling esoteric things it can do, I think this is much more basic, to help users preserve /home. All it needs to do is merely add it to /etc/fstab, and if encrypted to crypttab also. Not rocket science, yet a big benefit. I think an admitted weakness of the new installer interface is that it doesn't take existing installations into account as much as assuming new installations. > > When I get around to "fixing" this mess I will eliminate LVM, it's an added > layer of complexity that buys me nothing. Ok when it works but ... Fixing > means a re-install. Or really esoteric knowledge. At a minimum you need to made sdb4 a PV, and then add the PV to the existing VG, and then either create a new LV or resize an existing /home LV if it exists. And then create or resize an ext4 volume, which itself is a multistep process. And then possibly modify fstab to account for the new LV /home if it doesn't exist, and further figure out how to copy any data from a rootfs /home to the new LV /home.
