First.   Do not write any new files to the disks, not until you try to recover the ones you lost by formatting the disk.

 

Next,  send an e-mail to lime-technology pointing them to this thread.  Request this BUG get addressed and fixed.

 

Then look at this thread: http://lime-technology.com/forum/index.php?topic=5544.0

 

You can probably recover your files by following the procedure as shown in the wiki to rebuild the file-tree and scan the entire set of blocks in the partition to un-delete files.

 

Basically, you

Stop samba

/root/samba stop

Un-mount the data disk  (The file-system repair will not work on a mounted disk, so you must un-mount it)

umount /dev/md1

umount /dev/md2

md1=disk1, md2=disk3, etc.

 

Run reiserfsck with the --scan-whole-partition option

reiserfsck -–scan-whole-partition -–rebuild-tree /dev/md1

reiserfsck -–scan-whole-partition -–rebuild-tree /dev/md2

md1 = disk1, md2 = disk2, etc.

 

when prompted by reiserfsck program, answer "Yes" (capital "Y" lower case "es")

 

After the rebuild-tree is completed, you can re-mount the disk

mount /dev/md1 /mnt/disk1

mount /dev/md2 /mnt/disk2

etc... (make sure you mount md1 on disk1, md2 on disk2)

 

Then, you can re-start samba with

/root/samba start

to see the results.

thks a lot i try now

The rebuild-tree will create a lost+found directory on the disk.  The top-most folder names will be missing, replaced by substitute names given by the rebuild.  Sub-directories should in most cases have their names.

 

The scan-whole-partition will probably take 4 or more hours on a large disk.

thks a lot !!!!
