- I posted this once, and I haven't receved any replies. I guess those that
- have some clues are just studying up so they can give an accurate answer :-)
- I was hoping that someone out there would have some knowledge in this area ...
- so here we go again....
-
-
- Recently, I had a bad vtoc bucket show up on my disk. It was unreadable,
- and I finally chose to repair it by writing 0's to it (pehaps mistake #1). I
- then ran salvol, and everything seemed to work OK - meaning no unusual messages.
- I ran salvol with the -a option. Next time expire_news ran, I saw that I had
- files that were in a directory, but attributes weren't available. I began to
- question the quality of the salvage done by salvol. So, I set up a test case.
- The sequence belows shows what I think might be a bug. This work was done on a
- DN3500, with an 8621 controller and a Micropolis 170Mb drive.
-
- As an attempt to try and document my experiment, here is a summary:
- A) Initialize logical volume 1.
- B) Mount the volume, and use the DM to create a file called testfile.
- C) Get the uid of the file, and ensure that its there. Then dismount the
- volume.
- D) Run fixvol [here is where things get fun :-) ].
- E) Track down all pertinent structures related to the file (vtoce, bucket
- entry, BAT, and even look at the data block).
- F) Use the edit to clear the bucket entry (simulating the 'fix' I did when
- the block wasn't readable due to a header error).
- G) Mount the volume to see if the file has lost its attributes. It hasn't,
- which I think is strange, but probably due to a smart kernel thinking
- that nothing has changed, so use cached information).
- H) Dismount the volume
- I) Repeat G & H, because I didn't think things would work that way.
- J) Run fixvol again, to see if that convices the kernel that the cached
- information is bogus.
- K) Mount/ld/dismount - still thinks everything is OK.
- L) Salvol - I know its broken, lets see what salvol thinks. Use the -v,
- just to see if anything is found that I don't want fixed.
- M) Try salvol with -v again, to check that nothing was changed (nope).
- N) Mount/ld/dismount - check for file stats. Cache still intact.
- O) Salvol, default options - lets fix this :-(
- P) Mount - gee the file is broken (because it can't find the vtoce because
- the bucket was zapped. Why wasn't the file that was dropped found and
- catalogued with lost+found ?
- Q) Try find_orphans to see if that will find it. Nope - still broken.
- R) Dismount
- S) Fixvol - lets see what happened.
- T) The bucket is still empty (not fixed).
- U) What used to be a file_$file_type for uid 5D93314D.10022D27 is now a
- file_$dir_type for uid 5D9339E3.90022D27. Why? This seems to be a new
- (and bogus) directory block.
- V) Look at daddr 10c51 (I don't know why, but I don't think its relevant).
- W) Look at daddr 10c52 again - yep, its still a dir type. Looking at it
- shows that stuff is in it.
- X) Try looking at the block. After much trouble, it looks to be empty.
- Y) The BAT command shows that the block is in use (makes sense).
- Z) Try to check out this new directory uid. Its a directory that contains
- itself in its filemap (is this normal?).
-
- I'm confused, but here are my points/questions:
-
- Why did salvol create this bogus directory block?
- Why didn't it find my lost file?
- Why did it corrupt my lost file?
- Is there a better way to try and recover from this?
- Would it have been better to try a val vtoc in fixvol and do more manual repair
- before running salvol?
-
-
- Any help would be appreciated.

- Options are:
- 0 - EXIT.
- 1 [-fnb5uom] - initialize virgin physical volume.
- 2 [-fnb5u] - add a logical volume.
- 3 [-fnb5] - re-initialize an existing logical volume.

- f: don't re-format disk u: don't prompt user - use defaults
- o: make sr9 format disk n: make non-bootable volume
- b: apply bsd unix acls 5: apply sys5 unix acls
- m: build a multi-disk (e.g., striped) group
- 4 - delete a logical volume.
- 5 - list logical volumes.
- 6 [-e] - list badspots on disk or volume ... -e: list in decimal.
- 7 [-f] - initialize physical badspot list.
- 8 - create or modify an os paging file.
