<p class=MsoNormal>Let’s suppose you rename a file or directory.<o:p></o:p></p>
<p class=MsoNormal>/tank/widgets/a/rel2049_773.13-4/somefile.txt<o:p></o:p></p>
<p class=MsoNormal>Becomes<o:p></o:p></p>
<p class=MsoNormal>/tank/widgets/b/foogoo_release_1.9/README<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Let’s suppose you are now working on widget B, and you
want to look at the past zfs snapshot of README, but you don’t remember
where it came from. That is, you don’t know the previous name or
location where that file used to be. One way you could do it would be:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Look up the inode number of README. (for example, ls
-i README)<o:p></o:p></p>
<p class=MsoNormal>
(suppose it’s inode 12345)<o:p></o:p></p>
<p class=MsoNormal>find /tank/.zfs/snapshot -inum 12345<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Problem is, the find command will run for a long time.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there any faster way to find the file name(s) when all
you know is the inode number? (Actually, all you know is all the info
that’s in the present directory, which is not limited to inode number;
but, inode number is the only information that I personally know could be
useful.)<o:p></o:p></p>
