NFS export of LVM snapshot exports origin instead of snapshot
Subsystems (2)
hi,
[1.] One line summary of the problem:
NFS export of LVM snapshot exports origin instead of snapshot
[2.] Full description of the problem/report:
from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1071733
we're using LVM snapshots on our storage server to provide data for our live and staging instances.
there are two mountpoints on the server, one for the origin volume, and one for the snapshot that are exported using NFS to our live/staging instances (webserver)
today i noticed, that writes on our staging-webserver don't go to the snapshot as expected, but are hitting the origin volume, messing up all of our live data.
i checked the NFS-mounts and -exports and they look perfectly valid (staging mounts snapshot-mountpoint, live mounts origin-mountpoint) on the storage-server itself looking at the mountpoints, everything looks valid, too. i wrote some identifying test-files in each mountpoint in order to track them. no problem as long, as we look on the NFS-server itself.
but looking in the mountpoints of a NFS-client, it shows that the origin data was mounted.
i found no way to mount the snapshot again.
i'm not entirely sure, what component causes the problem. since the mountpoints look valid on the server itself, i would rule out LVM. i also would rule out the NFS-client, since it should not be able to see what the server hasn't exported. all clients can see the problem (lucid, maverick, precise).

[8.] Other notes, patches, fixes, workarounds:
whether the nfsorigin or nfssnapshot is exported seems to be dependent on the local mount order (first one wins)
similar symptoms: https://bugzilla.kernel.org/show_bug.cgi?id=13011
(fsid advice not working, reordering without effect) this one is mentioning a fix in kernel (2.6.29).
[8.1] output of my script provided at [6.] shows that snapshot is exported instead of origin
snapshot mountpoint itself is inaccessible

hi,
[1.] One line summary of the problem:
NFS export of LVM snapshot exports origin instead of snapshot
Quoted 8 lines
[2.] Full description of the problem/report:
from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1071733we're using LVM snapshots on our storage server to provide data for our live and staging instances.
there are two mountpoints on the server, one for the origin volume, and one for the snapshot that are exported using NFS to our live/staging instances (webserver)
The protocol references files on the filesystem using filehandles. The linux NFS server generates a filehandle that has a part which identifies the filesystem and a part which identifies the particular file (usually an inode and generation number).
The filesystem part in your case is probably a uuid which is part of what's copied when you snapshot (as are all the inode numbers). So you're left with filehandles that are the same for the two filesystems.
You can tell it to instead to use whatever integer you'd like using the "fsid=" export option (just don't used fsid=0, which has a special meaning).
Or, probably better--you should be able to be able to modify the uuid... Looking at the tune2fs man page, I think it should be:
tune2fs -U random /dev/vg0/nfssnapshot
--b.

today i noticed, that writes on our staging-webserver don't go to the snapshot as expected, but are hitting the origin volume, messing up all of our live data.
i checked the NFS-mounts and -exports and they look perfectly valid (staging mounts snapshot-mountpoint, live mounts origin-mountpoint) on the storage-server itself looking at the mountpoints, everything looks valid, too. i wrote some identifying test-files in each mountpoint in order to track them. no problem as long, as we look on the NFS-server itself.
but looking in the mountpoints of a NFS-client, it shows that the origin data was mounted.
i found no way to mount the snapshot again.i'm not entirely sure, what component causes the problem. since the mountpoints look valid on the server itself, i would rule out LVM. i also would rule out the NFS-client, since it should not be able to see what the server hasn't exported. all clients can see the problem (lucid, maverick, precise).

whether the nfsorigin or nfssnapshot is exported seems to be dependent on the local mount order (first one wins)

(fsid advice not working, reordering without effect) this one is mentioning a fix in kernel (2.6.29).[8.1] output of my script provided at [6.] shows that snapshot is exported instead of origin

The protocol references files on the filesystem using filehandles. The linux NFS server generates a filehandle that has a part which identifies the filesystem and a part which identifies the particular file (usually an inode and generation number).
sounds comprehensible.

The filesystem part in your case is probably a uuid which is part of what's copied when you snapshot (as are all the inode numbers). So you're left with filehandles that are the same for the two filesystems.
i can confirm that both filesystems by design have the same UUID.

You can tell it to instead to use whatever integer you'd like using the "fsid=" export option (just don't used fsid=0, which has a special meaning).
tried that already (using 2 and 6) and it did not work.

Or, probably better--you should be able to be able to modify the uuid... Looking at the tune2fs man page, I think it should be:
tune2fs -U random
/dev/vg0/nfssnapshot
we're using xfs in production, but it has some similar tool. i'll look into it tomorrow, because it doesn't works out that quick.
my problem with this issue is that we're running this setup for over two years now and the NFS server wasn't rebooted since half a year and the bug just showed recently. while we didn't had safety-checks in place to be sure what we mounted, we regularly simulated file-operations on a snapshot which never affected the origin volume.
