Hello List!
I just wanted to start using aufs but mounting an nfs branch
failed with kernel 2.6.15.7 and aufs 20070212.
So I modified fs/aufs/branch.h with this patch:
--- branch.h.orig 2007-02-14 16:03:04.000000000 +0100
+++ branch.h 2007-02-14 10:15:34.000000000 +0100

#define _AufsNoNfsBranchMsg "NFS branch is not supported"
-#if LINUX_VERSION_CODE == KERNEL_VERSION(2,6,15)
+#if LINUX_VERSION_CODE == KERNEL_VERSION(2,6,14)
#define AufsNoNfsBranch
#define AufsNoNfsBranchMsg _AufsNoNfsBranchMsg
#elif LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,19) \
Then I did on a diskless client where /usr is mounted on /dev/rd/0:
mount -t aufs -o br:/usr=rw:/apps/master/usr=ro aufsroot /usr
where /apps/master is an nfs mounted copy of an installed server.
It looks like it works except:
# find /usr > /dev/null
find: WARNING: Hard link count is wrong for usr/lib: this may be a bug
in your filesystem driver. Automatically turning on find's -noleaf
option. Earlier results may have failed to include directories that
should have been searched.
But I'm not sure if this warning can cause serious problems.
Why is it that on 2.6.15 NFS branch is not supported, what
test should I run to see if this problems exists on 2.6.15.7?
Cheers,
Peter
