Hi,
Solaris 10 x86 64bit, OpenAFS 1.4.12.1
bash-3.00# modload /kernel/fs/amd64/afs
can't load module: Operation not applicable
bash-3.00# tail -1 /var/adm/messages
Aug 1 20:08:16 unknown afs: [ID 718928 kern.notice] misc/nfssrv module
must be loaded before loading afs with nfs-xlator
I believe the responsible part of the code is:
openafs-1.4.12.1/src/afs/SOLARIS/osi_vfsops.c
[...]
530 #ifndef AFS_NONFSTRANS
531 #if defined(AFS_SUN55_ENV)
532 if ((!(mp = mod_find_by_filename("misc", "nfssrv"))
533 && !(mp = mod_find_by_filename(NULL, NFSSRV))
534 && !(mp = mod_find_by_filename(NULL, NFSSRV_V9))) || (mp
535 && !mp->
536
mod_installed))
537 {
538 printf
539 ("misc/nfssrv module must be loaded before loading
afs with nfs-xlator\n");
540 return (ENOSYS);
541 }
[...]
NFSSRV_V9 is definied as:
$ grep NFSSRV_ afs/SOLARIS/osi_machdep.h
#define NFSSRV_V9 "/kernel/misc/sparcv9/nfssrv"
This is of course fine only on SPARC systems and not on x86/64bit.
Before I run modload I also run in another terminal:
bash-3.00# dtrace -n fbt::mod_find_by_filename:entry'{;printf("%s\n",
stringof(arg1));}' \
-n
fbt::mod_find_by_filename:return'{printf("rc: %d\n", (uint)arg1);}' -q
ufs
rc: 2159728208
nfssrv
rc: 0
/kernel/misc/nfssrv
rc: 0
/kernel/misc/sparcv9/nfssrv
rc: 0
As expected mod_find_by_filename() can't match nfssrv in any provided
paths as it should be looking for misc/amd64/nfssrv.
I hacked the /kernel/fs/amd64/afs binary so it points to
/kernel/misc/amd64/nfssrv and now it loads fine:
bash-3.00# modload /kernel/fs/amd64/afs
bash-3.00#
bash-3.00# dtrace -n fbt::mod_find_by_filename:entry'{;printf("%s\n",
stringof(arg1));}' \
-n
fbt::mod_find_by_filename:return'{printf("rc: %d\n", (uint)arg1);}' -q
ufs
rc: 2159728208
nfssrv
rc: 0
/kernel/misc/nfssrv
rc: 0
/kernel/misc/amd64/nfssrv
rc: 2295909344
bash-3.00# modinfo | grep afs
243 fffffffff66f0000 c02f8 65 1 afs (afs syscall interface)
243 fffffffff66f0000 c02f8 65 1 afs (afs syscall interface(32 bit))
243 fffffffff66f0000 c02f8 24 1 afs (afs filesystem)
bash-3.00#
I checked the 1.5.75 release and it looks like there is the same issue
there.
