Is there an easy way to script interaction with fsdb? I'm trying to
rebuild a disk that failed recently and I'm searching for the inode
contains a directory that I need. However the entry in the root inode
lists the inode for the directory I'm after as 0. I know it is there
somewhere on the disk (or at least I hope it is) and I really don't
want to have to type every number between 1 and 14,292,725 to find it.
I thought if I could script fsdb I could do it much faster. In that
vein I tossed together this silly little script but I'm missing something
obvious because it doesn't work. Any suggestions besides don't do
this? :)
root@max(~)# cat foo.pl
#!/usr/bin/perl -w
open(FOO, "| fsdb /dev/vinum/mirror") or die "failed to start fsdb: $!";
print FOO "help\n";
close(FOO);
root@max(~)# ./foo.pl
