Do you mean the number 3001? I am sorry for my ignorance, but it is not clear to me from fsdb manpage what "blocks" means FS block and what disk block. And how can I use (calculate with) this numbers? How can I get the right number to pass to findlbk command (in the example above) to give me back the inode 3? If FS block is 16384 bytes, then it means 16384/512 = 32 disk blocks per FS block. If 3001 is FS block, then it means 3001*32 = 96032 disk block number. Am I right? fsdb (inum: 3)> findblk 96032 fsdb (inum: 3)> Again - findblk did not returned inode 3. So what is the exact formula to get the right findblk number and then right inode number as result of findblk command? I am still lost in terms (words) and numbers :( Miroslav Lachman
