[Dump-users] Can't read next inode ...

[<phu...@wi...>]

I am attempting to dump a filesystem which has developed a bad
block, and the bad block happens to contain some of the inodes.
Even though I specified a large -I number, dump is terminating
upon reaching the unreadable inode block.

How do I get it to just skip over unreadable blocks, including
unreadable inode blocks, and dump whatever can be read?

(Aologies if the answer is in the archives; when I attempted to
search them I got "Unable to connect to Search Server".)

This is on Red Hat 9 (yes, kind of old), and the filesystem is
not mounted.  The dump version appears to be 0.4b28:

$ rpm -qf /sbin/dump
