[gentoo-user] file system corrupted
Denis
for around 240 days without a reboot, and finally I went ahead and
rebooted yesterday, and during the boot-up, after performing the file
system checks, it says that my /usr partition (/dev/sda4) is corrupted
and needs to be repaired by running fsck *manually*. (my /, /usr, and
/home partitions all use ext3 file system). As a result of this, X
won't start because it complains about some libraries being
inaccessible. So I get a text prompt, I log into root, I try running
fsck, but it says that the partition is still mounted and running it
on a mounted partition could cause severe file system damage. I try
to unmount it, using "umount /usr", but it responds to this request by
"failed: device is busy".
How do I handle this? I'm sort of a newbie when it comes to this sort
of administration, so I would really appreciate any help. Could I put
some sort of a boot flag into Grub, so that the system doesn't mount
/usr when it boots up? I don't remember how to do this either.
Many thanks
Denis

I think `rc single` should do it.

Woah. My experience has been the opposite. Ext3 has never given me problems
since I started using it with RedHat 9/Fedora Core 1 almost two years ago. On
the other hand, trying to install a ReiserFS-based Gentoo system continually
gave me problems (failed attempts to mount it initially, sometimes would
hardlock during disk-intensive things like `emerge --sync` or compiling
something, etc).
*shrug* Oh well...

Yeah, I agree. I've lost data on unix-like machines five times. Once with ext2 (although I was running GNU/Hurd, so, there was probably something else going on), once with FFS due to hardware failure, and *three* times on linux boxes that were running ReiserFS. YMMV, but I haven't had any problems with ext3 (other than speed issues), JFS, or XFS.

system. :-)
I've had problems with both but I like ReiserFS a little better and
here's why...
Image that you have a database server with 1-2 terabytes of disk. When I
use ext3 when I fsck this I'm hosed, last time it took about 2 hours to
fix a relatively minor problem. With ReiserFS as my database FS, it's
much, much faster, minutes and not hours. Reiser gets my systems back to
runlevel 3 faster to me. I'll use ext3 for compatibility but reiser for
speed and faster disk repairs.
Bottom line is both are good but try to pick one that best meets the
needs of your environment.
Cheers,

This is going-off topic, but speed issues? Are you sure you're using directory
indexing? (This feature keeps the filesystem structure in a hashed binary tree
rather than series of linked-lists, which improves access time considerably on
most Ext2/Ext3 filesystems)
Try running `tune2fs -O dir_index /dev/<partition>` on your Ext2/Ext3
partition(s) to enable this. You'll need to unmount the partition before doing
this (booting from a LiveCD if needed). To re-optimize a Ext2/Ext3 filesystem's
directory structure, you'll then need to run `e2fsck -D /dev/<partition>` (as
previously mentioned, this should be done while the filesystem is not mounted).
That prcoes may take a long time depending on the partition size...
If you're further interested, I've posted a thread[1] in Gentoo's DT&T forum
that has more information.

Agreed about the alternate partition; I have a 5.5G partition for this,
but it can probably be reduced to maybe 2G; this NEEDS to be a primary
part, so it can have it own full boot sequence -- do NOT rely on
sharing a /boot partition with the main install, not even the grub in
the MBR for the whole disk; this has to be markable as bootable, which
is also a reason to keep the m$do$-style MBR. Alternate drive is
better, if your bios can boot from more than one drive; again, NOT using
a grub-mbr from the main drive to find the alternate drive (but can
allow one-or-both drives to use grub/lilo MBR's). LiveCD is a very good
alternate, and cheap.

Yes. I think that should allow you to run fsck ok, but I haven't done
this often.
Surely some brighter minds than mine can comment if we interrupt their
knome vs gde^w^w^w ext3 vs ReiserFS flamewar frequently enough.

Yes, I'm aware of indexing, and I use it on a couple of machines where it's appropriate. It does seem to speed reads quite a bit, although, for overall useage, I've still found it to be slower than JFS on the same hardware (though not as slow as say, FFS on BSD or Solaris). As you posted in that thread, it does help when you're dealing with deep directories. IIRC, it does incur a slight write hit, which on a system that's got rather balanced I/O, might not be worth the tradeoff (e.g. a mail server, or a box running say, Squid). For something where reads are important, however, it speeds things considerably.
I haven't found, however, a benchmark that tests things to my satisfaction. For example, I'd like to see a benchmark where they look at directories filled with lots of small files (think Maildir), and also mounted -o sync, testing read and write performance, as well as storage efficiency.
I've kind of gotten in the habit of choosing the best tool for the job. On my MythTV machine, I run XFS, because I'm dealing with large files (2.2gb/hr of video). On my desktop it's ext3. On my notebook, I'm still using ext2 for power management reasons (turning off hd with hdparm when running on battery I still haven't gotten to play nicely with any journalling FS). I mostly run BSD on my servers, so I don't have a choice other than slow, reliable FFS.

I've noticed that too, but if gaining reliability means losing a few gigs
of available filesystem space I have no problems with it ;-)

Use hashed b-trees to speed up lookups in large directories.

I'm not an expert or guru, but I'll sure try. From what I understand, the
filesystem normally stores the block and inode information in a very linear
fashion. When you enable this feature, this information is then stored in a
hashed B-tree [1] so that the information can be accessed and manipulated
faster. However, as far as I know this does incur a small storage penalty for
storing the extra node structure information.
Hope that helps. :-/

Don't disregard the Pentium M so quickly. The Pentium4 is a _horrible_
architecture: Intel wanted a CPU that could be clocked _very_ fast (I think the
current top speed is ~3.4 GHz). However, the P4 can't really do a lot per cycle.
The Pentium M[1] though..wow. That's actually a really great chip. They (Intel)
took the awesomeness of the Pentium3 family, added the cool SSE stuff from the
P4, gave it a lot of on-die cache (the Dothan core has 2 MB L2 cache), increased
the instruction pipline, and also made it consume a _lot_ less power. In fact,
when the P4 came out originally I honestly thought that it would be the end of
Intel; then they started producing their "Centrino"[2] laptop chipset (Pentium M
with Intel mobile chipset and integrated Intel PRO/Wireless). It consumes very
little power but it can perform really well. In fact, My brother gave me a good
rule-of-thumb about this when he was explaining it to me a while back: Add 1 GHz
or so and that's the equivalently rated P4. For example, a 1.5 GHz Pentium M
will likely perform just as well, if not better, then a ~2.5 GHz Pentium 4.

Intel is moving towards incorporating a lot of Pentium M features in
their desktop processors. Unfortunately the results for Linux are
somewhat mixed...extra cache is good, but gcc treats it as a regular P4,
and misses out on a bunch of features. Check out:

Ok, since nobody is actually bothering to _read_ article that I linked
to, let me quote a small piece:
"Pentium M's Micro Ops Fusion, local branch prediction and general
optimizations across integer division and register access are completely
ignored by the compiler, even when setting - march=pentium-m, since most
compilers (particularly anything before GCC 3.4.2) tend to just
categorize Pentium M as a P6 processor with a higher clock." -Anandtech.com
From what I can tell from the change logs for GCC 3.4.2 and 3.4.3,
nothing has changed in this regard.
Anandtech.com might be completely wrong about GCC, but I would be _very_
surprised. The article has many benchmarks for different types of
applications, if anyone is actually interested.

No pentium m processors have integrated wireless. the pentium m is a
cpu.
However centrino machines have built in wireless, its part of the
centrino spec. centrino also uses pentium m. but just because your
machine has a pentium-m cpu, doesn't make it centrino.
lspci should tell you if you have a wireless chipset in your machine. If it has a centrino sticker, then it should have wireless.
Hope that clears up the confusion.

I have a feeling that if you installed Winders & pressed this button,
you might get a "wireless networks" icon next to the clock. On some
machines (eg IBM StinkPads) the icon for the wireless on/off is in blue
on one of the fucntion keys, and to active the wireless card you have
to press a blue function button on the bottom left of the keyboard to
active it. If it's a button all on its own that's not responding, it
might also be worth checking the BIOS.
What make & model is your laptop?

I went off-topic from the original post and then went even further off-topic
from the topic which I deviated to. Sorry about that all. I did that on the
Developer Shed forums too a lot recently. :-/
Maybe I just need more caffeine. Again, sorry for the disruption all. :-)

FYI here is an lspci output from a Dell Centrino machine. The Broadcom
entry at the bottom is the builtin wireless card, which incidentally
only works with NDISWrapper.

AFAIK the Centrino branding requires Intel/PRO wireless stuff, not
broadcom. How does your machine get a centrino sticker? or is broadcom a rebadged intel wireless set? or has the standard been relaxed?

I don't know that I have a good answer to that, a quick Google search
did not reveal much. I believe that in the early days of Centrino Intel
was forced to partner with other WIFI chip makers to meet their release
date. Which may have set the standard lower than was expected from the
very beginning. It may also be as simple as the chassis being
pre-stickered Centrino and assembled with a Broadcom chip due to a back
order on the Intel chips.

Yes, *WHY* does it cost more without WindoZZZe? (Answer: Because
MonopolSoft threatens vendors into doing this.)
I suggest NOT buying from vendors that do this.
If Linux ever reeally becomes *important* in the $$market, they'll pay
for that behavior.
Hopefully, that will feed back to MS & hurt them even more.
