I accidentally lost a file (and one of my cat lives in the process).
so i run :
reiserfsck --rebuild-tree -S -l /root/recovery.log /dev/md2
and all the deleted files found were placed under a lost+found dir.
I found my file and all is good, apart from 1 thing:
df returns double (almost) the used space on disk.
Is it safe now to delete the the folder lost+found? or only its contents?
