Kernel Panic 2.6.14.5 with xfs

Greetings,

With a vanilla kernel (2.6.14.5), I checked XFS
and rebuild the kernel; by following standard procedure;
Make menuconfig
Make bzImage
Make modules
Make modules_install
Make install.

All went on with out throwing any errors. 
Then I rebooted the system, but a kernel panic is occuring
The following are the message from the console;

==========================================================
Booting 'Red hat Enterprise Linux AS 92.6.14.5)'

Unexpected xfs_buf_item_init initialization and inflexible xfs_buf_item_zone

Hi,
	While changing the (current default) number of inode allocated  at 
once, I found two things a bit unexpected:

Section A:
----------
xfs_buf_item_init()

        /*
          * chunks is the number of XFS_BLI_CHUNK size pieces
          * the buffer can be divided into. Make sure not to
          * truncate any pieces.  map_size is the size of the
          * bitmap needed to describe the chunks of the buffer.
          */
         chunks = (int)((XFS_BUF_COUNT(bp) + (XFS_BLI_CHUNK - 1)) >> 
XFS_BLI_SHIFT);
         map_size = (int)((chunks + NBWORD) >> BIT_TO_WORD_SHIFT); ---> 2

	For 4096 block page (linux default), one map is required per page. 
Given this, line 2 appears odd. Instead, it should be

map_size = (int)((chunks + NBWORD -1) >> BIT_TO_WORD_SHIFT);

Also, chunks calculation may go well off the mark of the blocks are not 
page aligned. The code does not block alignment check. It only checks 
for sectoral alignment. For example, lets say I need  32768 
pb_buffer_length. However, the offset is not 4096 aligned. Lets say it 
starts at, 2048. Given this, _pagebuf_lookup_pages will prepare 8 + 1 pages.
page_count = page_buf_btoc(end) - page_buf_btoct(bp->pb_file_offset);

same here!  not much response from technical xfs related questions (actually
a goose egg), but spam-a-lot.

in the process of converting all systems to ext3, so will be rid of both
soon.

Problem with mixed Files

Hi,

We are using XFS on an Mailserver. We have a strange Problem which could
be tracked down to Filesystem or Hardware level.

The Problem:
Some of the stored mails get`s mixxed with various contents of the
Filesystem or other Mails. The Files "look" normal dumped with "od" - no
strange content. This Problem could be reproduced. If we send and
massive amount of Data slighly smaller than Blocksize some of the
generated Files gets mixxed. If i should guess, i would say that the
files get filled with content to fill the Inode.

One of this Files:

mail8:# cat 1136200241.M378338P21770V000000000000000FI2D87F6C0_0.*

RE: Kernel Panic 2.6.14.5 with xfs

Thankyou Shailendra for the response.
With further experiment, I went on to disable to ACPI in the kernel
config and rebuild and booted successfully with XFS (without ACPI).
Don't know how true it is, but many people are saying that DELL have an
error prone ACPI firware and not work well with Linux in many cases.

Any comments for discussion.

Thanks
Jose

Hi Jose,
	Your configuration doe not appear to be saved. You are saying
that you have selected XFS, however boot messages is clearly showing
that the file system type is 0x83.
	Did you rebuilt the initrd image ?

No need for hyperbole...

There were some problems with the machine hosting the list over last week, and 
people were off on vacation, so it didn't get immediate attention.  While we've 
resisted closing the list to non-subscribers in the past, we're talking about 
revisiting that decision.  It's just too hard to keep up with the spammers.

You may find that you've got a new set of problems ;-)  Nothing against ext3, 
but every filesystem will probably have it's own set of idiosyncracies to deal 
with.

help with using xfs filesystem

Dear Sir, or Lady,

	  I am sorry to disturb you. 
      My operating system is Red Hat Linux 9. And the Linux kernel is kernel-2.4.20-8smp. I am trying to use xfs
filesystem. I have downloaded the "kernel-smp-2.4.20-20.9.XFS1.3.1.i686.rpm" and
"xfsprogs-2.5.6.src.tar.gz" packages. Can you do me the favor to tell me what and how I shall do, since I am
pretty new user of linux operating system?
     Your kind help are appreciated!

　　Best wishes　　　　			

　　　　　　　yours sincerely
                           Clark
