[linux-lvm] Does LVM compile on Sparc64?

[linux-lvm] Does LVM compile on Sparc64?

[Thomas Bader]

Hi Everybody

I got the source of Linux 2.2.20 and applied the patches of
LVM 1.0.1 (including Stephen Tweedie's rawio patch and
linux-2.2.18-sparc64.diff).

The patches do apply well, but it seems like there are some
missing definitions in include/linux/lvm.h:

duke:/usr/src/linux# make vmlinux
[snipped]
sparc64-linux-gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -m64 -pipe -mno-fpu -mcpu=ultrasparc -mcmodel=medlow -ffixed-g4 -fcall-used-g5 -fcall-used-g7 -Wno-sign-compare   -c -o ioctl32.o ioctl32.c
ioctl32.c: In function `do_lvm_ioctl':
ioctl32.c:2570: warning: assignment makes pointer from integer without a cast
ioctl32.c:2604: structure has no member named `inode'
ioctl32.c:2645: warning: assignment from incompatible pointer type
ioctl32.c:2646: structure has no member named `inode'
ioctl32.c:2653: structure has no member named `inode'
ioctl32.c:2666: structure has no member named `inode'
ioctl32.c:2545: warning: `v' might be used uninitialized in this function
make[1]: *** [ioctl32.o] Error 1
make[1]: Leaving directory `/usr/src/linux-2.2.20-RAID/arch/sparc64/kernel'
make: *** [_dir_arch/sparc64/kernel] Error 2
duke:/usr/src/linux#

ioctl32.c:2604 looks like:

v->pv[i]->pe = NULL; v->pv[i]->inode = NULL;

v makes use of vg_t and v->pv makes use of pv_t (both
defined in lvm.h)

lvm.h on sparc64 is completly different than on Intel.  I'm
just wondering now, if all the stuff gets fixed, if I apply
the struct member 'inode' to pv_t, like it is done on Intel.

Or are there any other patches, to run LVM 1.0.1 on sparc64?

Thanks & Cheers
Thomas

See http://lists.sistina.com/pipermail/linux-lvm/2001-December/009950.html

for a patch that should work.

I'll make a proper 2.2 one next week.

Oh nice.  I didn't found this patch yet (searched with
google).

I applied it and it compiled without error.  But now, my
machine does not boot anymore - it hangs directly after it
has detected my raid arrays:

-->-->-->--
md: updating md0 RAID superblock on device
sdb1 [events: 00000022](write) sdb1's sb offset: 3145664
md: serializing resync, md0 has overlapping physical units
with md2!
sda1 [events: 00000022](write) sda1's sb offset: 3145664
.
... autorun DONE.
--<--<--<--

After this, it won't continue booting up.  I booted a backup
copy of my kernel image.  I saw, that after the above step
("... autorun DONE.") the kernel tries to mount my root
partition read-only.

My / is on a RAID1 array (/dev/md0) with ext2.  Does the LVM
code touch anything of these two?

Any other hints?

Thanks & Cheers
Thomas

I honestly don't know what that should be, sorry. I know for sure that LVM has
worked for me on SPARC64 with those patches applied so all I can suggest is to
check the rest of your kernel config and maybe do a clean rebuild of the kernel.
