#10673 - 06/22/10 12:44 AM Anomalous "Restore" results?
artie505 Online


Registered: 08/04/09
I just restored my SL volume to an empty volume (with the "Erase...." box checked), and the sizes of the source and restored volumes are wildly different. (I got almost identical results from a second try.)

Source volume:
Code:
Artie-s-Computer-4:~ artie$ sudo du -xhd1 /
Password:
 40K	/.fseventsd
 31M	/.Spotlight-V100
  0B	/.Trashes
  0B	/.vol
882M	/Applications
3.9M	/bin
  0B	/cores
4.5K	/dev
1.0K	/home
1.5G	/Library
1.0K	/net
  0B	/Network
729M	/private
2.6M	/sbin
1.7G	/System
184M	/Users
379M	/usr
4.0K	/Volumes
5.3G	/
Artie-s-Computer-4:~ artie$

Restored volume:
Code:
Artie-s-Computer-4:~ artie$ sudo du -xhd1 /
Password:
336K	/.fseventsd
 37M	/.Spotlight-V100
  0B	/.Trashes

3.3G	/System
184M	/Users
935M	/usr
4.0K	/Volumes
7.2G	/
Artie-s-Computer-4:~ artie$

Does that Terminal output make any sense to anybody, or do I just not particularly understand what I did?

Thanks.

Is there a significant capacity difference between the source and destination volumes? I'm wondering if the source is using smaller allocation blocks, and therefore wasting less space.

almost certainly an allocation block size difference.

Make a small file. As in, open text edit and make a one word text file. Save it on one volume and copy to the other. compare file sizes.

I know that a "restore" (assuming that means Disk Utility) does intentionally skip some stuff... but those results look bizarre. A few years ago i'd be inclined to go with allocation block size as well... but i'm not so sure now (i've never seen an OSX volume that wasn't 4KB).

Artie should tell us about these two disks (format, etc.), perhaps with

diskutil info /Volumes/*

...or something. [i.e., replace the asterisk with the real name]

I looked briefly for some command that shows allocation block size, but i don't find anything handy. [it might need to be scripted.]

--

I'd almost be inclined to think either one disk is not HFS+ journaled, or it needs repair.



Late EDIT:

Quote:
>> $ sudo du -xhd1 /
:
>> 4.0K /Volumes
:

The identical 4k size for both /Volumes folders seems to rule out the allocation block theory. [that 4k is probably the symlink to / which usually takes a single byte ("/"), therefore consuming a single allocation block.]

If both volumes pass muster with Disk Utility (or preferably DiskWarrior), then some method of determining the file differences is the way to go. A GUI folder sync with a preview feature (such as ChronoSync) could display what items differ (in just the two /sbin folders for example). Or a command line attempt might look like:

sudo diff -qr /Volumes/source/sbin/ /Volumes/restore/sbin/ |grep '^Only in'

The grep is just to skip over files which do exist on both sides, but have different contents. [other tools such as rsync -nrxv --delete could also be used, if done with care (i.e., do not remove the -n). But again, rsync will also display any files which exist on both sides, but have different contents (unless there's an option i'm not familiar with... in fact i bet there is one, so i'll look for it). Meanwhile, go with diff or a GUI folder sync utility.]

Kind of interesting that /Users weighs in at the same 184 MB on each volume.

Sure is. It would appear that Artie has found another SL bug of some sort.

Perhaps the "Erase" option malfunctioned... in a weird way.

Hmm, but then what about the 1.0K for /home and /net? (FWIW, when I run the command, I get both of those, plus 512B for /dev.)

If a single-byte file consumes a full allocation block, wouldn't a 512-byte or 1024-byte file likewise consume a full allocation block? Or am I not understanding what you're saying?

/home and /net are some strange (synthetic) filesystems unto themselves. They represent some sort of networked "autofs" stuff which isn't part of the normal (physical) HFS+.

[i don't know enough to explain it any better.]



/dev is also an oddball. If i attack it directly, it gives me:

sudo du -xhd1 /dev
du: Can't follow symlink cycle from /dev/fd/3 to /dev/fd/3

Identical!

(I've never heard of different sized allocation blocks in different volumes; I thought 4k was default...standard...carved in stone...unless willfully changed by a user, of course.)

Nope... I'm restoring a 25Gb volume with about 6.5Gb used to a 15Gb volume.

This is 100% reproducible, and with comparable, if not identical, results. (There are, invariably, huge, almost identical, differences in /System and /usr and smaller differences elsewhere.)

As a benchmark, I booted into 10.5.7 and ran a restore (Has restoring always changed the name of the destination volume to that of the source volume? ...extremely confusing!!!) with these results:

Code:

Artie-s-Computer-4:~ artie$ 

I then looked deeper into /System and /usr in the source and destination volumes of my initial post (I've got the entire volumes' output if anybody cares to see it.) with these results:

(It would be neat if there was a way to line up the two results side-by-side.)

I suppose the next logical step is for me to file a bug report with Apple, but I'll wait for additional feedback before doing so.

Artie-s-Computer-4:~ artie$ -

I think you were meant to enter the actual names of the two volumes in place of source and restore. wink ("No such file or directory" is, in my limited experience, almost invariably a clue that a command has been entered incorrectly.)

Thanks.

My initial reaction was "Duuuh!" (I'm truly brain-burned from this issue which, in one manner or another, has been going on for well over a month, now.)

But...

Code:
Artie-s-Computer-4:~ artie$ sudo diff -qr /Volumes/HD/sbin/ /Volumes/HDx/sbin/ |grep '^Only in'
Password:
Artie-s-Computer-4:~ artie$ 

I dunno? confused

That's a surprising "difference". [i.e., none.]

Okay Artie-pants wink ... let's try this then:

ls -ago /Volumes/*/sbin


(also, the first command without the
grep filter should have output: diff -qr /Volumes/HD/sbin/ /Volumes/HDx/sbin/ —but, ls -ago /Volumes/*/sbin should be equally informative).


While we're at it, let's look at /bin as well (since it has less files and a bigger size discrepancy):

ls -ago /Volumes/*/bin


--

BTW, i'm wondering now if this all isn't simply due to SL's new "compressed storage" feature in HFS+. The boot volume maintains a compressed version... but a restore operation will expand the data onto the backup volume.

That would also explain why Finder's Get Info measurement is off as well:
$ du -hxd1 /sbin
2.6M /sbin

If i look at /sbin with a Finder Get Info window, it reports 7.5 megs.


Also... between /bin /sbin and /usr there are a fair amount of multi-linked files. I wonder to what extent that linkage gets preserved, or what may be copied over as multiple file instances. [we can check that if you like.]

Scratch multi-linked files... I think it's the compression mainly.

Edit: As I mentioned in my keychain thread, I'm going to do an erase and install; maybe it will clear up this issue (too, hopefully).

I won't do it, though, until you're done investigating...soon, I hope.

Well, it's a comparison of the number and size of items in /sbin and /bin on the source with the number and size of items in /sbin and /bin on the clone. As far as I can tell, they're identical.

Yet the number of 512-byte blocks used by those files is wildly different between the source and the clone:

Quote:
/Volumes/HD/sbin:
total 5640

/Volumes/HDx/sbin:
total 14728

/Volumes/HD/bin:
total 8640

/Volumes/HDx/bin:
total 20144


So somehow, identically-sized files are occupying a larger number of blocks on the clone.

This stuff is largely over my head, but a perusal of the Installation page from Mac OS X 10.6 Snow Leopard: the Ars Technica review provides some interesting details about Snowy's compression techniques, including this tidbit:

The answer to that lies in how HFS+ allocates disk space. When storing information in a data or resource fork, HFS+ allocates space in multiples of the file system's allocation block size (4 KB, by default). So those eight bytes will take up a minimum of 4,096 bytes if stored in the traditional way. When allocating disk space for extended attributes, however, the allocation block size is not a factor; the data is packed in much more tightly. In the end, the actual space saved by storing those 25 bytes of data in an extended attribute is over 4,000 bytes.

I wonder if the expansion of the compressed data is occurring because the restore operation is making a file-level copy of the source rather than a block-level copy? (Since your target was smaller than your source, a block-level copy wouldn't have been possible; also, you'd've needed to be booted from a third volume, since both source and target need to be unmountable for a block-level copy using ASR.) (Which leads to the following question: were you booted from a third volume? If so, was it a Leopard volume?)

Pretty sneaky too how the extended attributes are all hidden when viewed in Snow Leopard.
[not a single item above listed with ls shows any "@" at the end of the permissions string.]

Artie, if I remember right, when you ran that tool I gave you earlier to check if files were compressed or not, it turned up "not compressed" for all the files you ran it on for the volume cloned using Restore, right?

If my memory's right, then that's all this is. The original files were compressed, the cloned ones aren't. The restore tool simply didn't preserve the compression, which isn't surprising, since it's probably just copying the files, and the way the HFS+ driver works in SL, if you copy a compressed file, it doesn't compress the result.

It's non-ideal, but it's still better than the custom Bombich rsync that backuplist+ uses, which tries to preserve the HFS compression, but apparently is prone to messing it up and corrupting the whole file.

The best way to avoid all these sorts of problems is always to click the "Erase Destination" check box when cloning. When using the Restore tab, this will often result in a block copy, which is pretty much guaranteed to be exactly the same as the original.

For those who may be curious (as i was), more on Bombich's patch here: rsync and hfs+ compressed files damaged

1. I didn't know that about block-level copies (not to say that I've even fully digested the difference between file and block-level copies yet).

2.Yes, I booted into my Leopard volume to restore the SL volume.

Does that hold true even if the destination volume has been erased beforehand?

hfs_comp_tool?   confused  Google comes up totally dry.

Easy enough. File-level copies individual files one-by-one... so they will not end up in the same "physical" locations on the target disk. Logically identical pathnames, yes... but not in terms of "byte addresses" on disk. That's why/how a (normal) restore can "defragment" a disk.

Block-copy literally duplicates data by disk sectors (has no notion of "files" at all). Some call this the only true clone. [if the source disk has directory damage however, it will be faithfully reproduced on the target.]

Apparently 10.5 and 10.6 will treat the new xattrs differently. (10.5 is unaware that they are "special" xattrs).

Definitely. Disk Utility doesn't care if the disk is already erased or not. It *only* does a block-level copy when we tell it to do the erasing.
