A SCSI disk attached to a Sun 3/60 recently began having problems. I was able to do a full dump of the data from the partition after taking it offline. The problem is that a number of the blocks were "bad" and could not be read during the dump. Among these blocks was the file that contained a directory just above the root directory. The problem arises because although the top of the directory tree is missing, the data beneath is still there. I have verified this by actually looking through the data on the tape (Uggh!). Figuring that I could extract the information using the -m option of restore I went ahead with the operation. The m option (supposedly) lets you restore information by inode. No go. Restore does not admit to the data, even though I can see the inodes, filenames, and data associated with the inodes on the dump tape. This is causing a large hunk of important data to be unavailable. (yeah, I know, if it was so important why weren't they backing it up often?) So... the question is, does anyone have a program (or patch for restore) that will permit me to access the data on the tape? I would even be willing for the filenames to be the inode numbers (although matching the inodes to filenames where they exist would be nice). Does Sun (or anyone else) even sell such a beast? Does anyone one have better documentation on how the data is stored on the tape than the dump(5) man page. Aydin Edguer edguer@ces.cwru.edu
