November 30, 201015 yr Hi everyone, I hope someone can help. Joe L. - hope you see this. So a friend of mine deleted all the folders and files inside a usershare. It was an important folder and he really needs to try to get the data back. His system is setup as: Parity: 2TB Drive 1: 1.5 TB Drive 2: 1.5 TB Drive 3: 1.5 TB The share was spread across all 3 disks. I tried to run the reiserfsck --rebuild-tree command shown in another thread. I ran the command on Disk 3 since that drive had only about 30GB of data on it (which I copied to another drive not on the system just in case. Unraid was started as I did the following: 1. turned off samba. 2. unmounted md3 Refreshed the unraid web interface and Drive 3 showed as unformatted. 3. Ran: reiserfsck --check /dev/md3 no corruption found 4. Ran: reiserfsck --rebuild-tree -S /dev/md3 5. Tried to remount MD3 and got the error below. Unraid still shows the drive as unformatted. Can I just add md3 to the mtab file and then try to remount? I have that file below as well. Pass 3 showed the following: ####### Pass 3a (lost+found pass) ######### Looking for lost directories: relocate_dir: Moving [2 14 0x0 SD (0)] to [2 781 0x0 SD (0)] relocate_dir: Moving [2 14 0x1 DIR (3)] to [2 781 0x1 DIR (3)] /2_781get_next_directory_item: The entry ".." of the directory [2 781] pointes to [2 5], instead of [2 780] - corrected rebuild_semantic_pass: The entry [2 18] ("Info.plist") in directory [2 781] points to nowhere - is removed vpf-10650: The directory [2 781] has the wrong size in the StatData (112) - corrected to (80) Looking for lost files: rewrite_file: 11 items of file [166 168] moved to [166 782] Flushing..finished Objects without names 2 Dirs linked to /lost+found: 1 Files linked to /lost+found 1 Objects having used objectids: 2 files fixed 1 dirs fixed 1 Pass 4 - finished done 0, 0 /sec Deleted unreachable items 30 Flushing..finished Syncing..finished ########### reiserfsck finished at Tue Nov 30 04:17:10 2010 ########### root@data:~# root@data:~# mount /dev/md3 mount: can't find /dev/md3 in /etc/fstab or /etc/mtab root@data:~# MTAB FILE: fusectl /sys/fs/fuse/connections fusectl rw 0 0 usbfs /proc/bus/usb usbfs rw 0 0 /dev/sde1 /boot vfat rw,noatime,nodiratime,umask=0,shortname=mixed 0 0 /dev/md2 /mnt/disk2 reiserfs rw,noatime,nodiratime,noacl,nouser_xattr 0 0 /dev/md1 /mnt/disk1 reiserfs rw,noatime,nodiratime,noacl,nouser_xattr 0 0 shfs /mnt/user fuse.shfs rw,nosuid,nodev,noatime,allow_other,default_permissions 0 0 Please help. I'm looking to do this for the other 2 drives, but want to make sure that I don't mess anything up with those drives because they contain lots of data. I'm hoping to just remount that drive and have UNRAID see it as not formatted. I then want to browse disk 3 and go to the lost+found folder to see if it recovered anything. I don't think there was much to recover on this drive. I think most of the files in the share were on Disk 1 and Disk 2
November 30, 201015 yr The reason the "mount" failed is that you did not type the entire command needed. You would need to type mount /dev/md3 /mnt/disk3 Or, even more easy, you could stop the array, and then re-start it, and unRAID would mount it for you. It would also start SAMBA so you could see the lost+found folder it created via the LAN as a new share. Joe L.
November 30, 201015 yr Author Thanks, Joe. I was hoping it was something simple like that. I'll give that a try and see what happens!
