Hi,all

Just tried 2.4.17 and this was the first non-ac kernel that was able to 
boot on this machine :-)  anyways things seem to be running ok,but 
there's lots of these errors:  kernel: invalidate: busy buffer

I searched archives and the net,but didn't find any solution to what's 
causing it..Might be LVM ?? Something else ?? Anyone have the same 
problems ??

best regards

Christian

Dear LVM gurus

I've installed LVM on several computers over the years, generally without
problem, but now I've hit a box where I can't make it work:  This is a P4
with two 60GB IDE drives, hda and hdc.  The Kernel is a Redhat 2.4.17
(custom 0.6 fwiw) which I understand is an -ac flavor kernel.  It would
seem that because of compatibility issues with aquote - unrelated to LVM -
I need this -ac hack present.

I downloaded and installed the userland tools 1.0.3 and had a beautiful
patch created. Trying to apply the patch with --dry-run gives a couple of
errors though, so I didn't dare applying it.

Instead I just compiled the kernel with LVM support in the kernel
(whichever is present in the 2.4.17 kernel, not as not module) and
everything seems fine - at least no complaints. This i've done several
times before without getting into trouble.

Rebooted the kernel, everything still fine. ran vgscan (tookforever but
eventually came back)  followed by vgchange -a y, which also was ok.

pvcreate on both the partitions (one on each disk) goes fine, and so does
vgcreate (again, takes forever, but finally...)

Now the problem: lvcreate dumps core. Doesnt matter how much or little
space I create, what I call it, if I use just one pv or if I try to slice
it.

I notice in my /var/log/messages that I get MILLIONS (really) of errors:
kernel: invalidate: busy buffer
last message repeated 12233432 times
last message repeated 534252times
last message repeated 545234242 times

What am I doing wrong? Is this error related to the missing kernel
patching?

How can I patch a standard kernel for both -ac and LVM ? As I understand
it they both require a "clean" kernel to apply good?

Sorry for the perhaps stupid quiestions, but I am not a kernel guru - I
only know just enough to get myself into trouble :-)  I *did* read the FAQ
and I *did* search google (usenet) - didnt' find the answers tho...

TIA!
Rene

I received your message via the list so you're not the only one :)  However I cannot give any assistance with your issue.  My apologies.

Just letting you know you're not alone on the list,

Yes in some situations. Its fixed in 2.4.19pre5-ac2 and a bit before

Hope this helps,

The invalidate: busy buffer message comes from fs/buffer.c, inside
invalidate_bdev().  It's just a warning message indicating the buffer has a
positive b_count -- presumably, somebody is still using it.  In this case,
the code *doesn't* destroy the buffer, so it should be harmless.  Don't know
why you're getting millions of them, though.  I remember seeing them before
(during vgscan), but never in that quantity.

I also don't know why your lvcreate dumps core.  How recent are your LVM
tools?  Try using the -d option to lvcreate to see how far it gets, or run
lvcreate from within gdb.
