Re: [ovirt-users] NFS and pass discards\unmap question

[Sergey Kulikov]

Thanks! I think now It's question to NetApp, when they'll make 4.2 available,
I've tried to manually mount v4.2 on host,
but unfortunately:
# mount -o vers=4.2 10.1.1.111:/test /tmp/123 
mount.nfs: Protocol not supported

so, my NetApp is vers=4.1 max (

Does not work for me - I tried all combinations of:

NFS Version: Auto Negotiate
NFS Version: V4
NFS Version: V4.1
NFS Version: V3 (default)

With:

Additional mount options: nfsvers=4,minorversion=2
Additional mount options: minorversion=2
Additional mount options: vers=4.2

It always fail with this error:

Error while executing action: Cannot edit Storage Connection.
Custom mount options contain the following duplicate managed options:
...

Engine does not let you specify minorversion, nfsvers, or vers.

Adding managed 4.2 item to the menu seems like the way to fix this.

Looks like ovirt engine does not allow nfs version 4.2.


But custom options can be used.
Y.


We have this RFE:
https://bugzilla.redhat.com/1406398

So practically, both sparsify and pass discard with NFS are useless
in the current version.

I think this should be fix for next 4.1 build.

Looks like ovirt engine does not allow nfs version 4.2.

We have this RFE:
https://bugzilla.redhat.com/1406398

So practically, both sparsify and pass discard with NFS are useless
in the current version.

I think this should be fix for next 4.1 build.

Unfortunately I can't browse this bug:

Can you email me details on ths bug?
I think that's the reason I can't find this fix for rhel\centos in google)

Re: [ovirt-users] NFS and pass discards\unmap question

[Sergey Kulikov]

Hm... maybe I need to set any options, is there any way to force ovirt to mount 
with this extension, or version 4.2
there is only 4.1 selection in "New Domain" menu.
Current mount options:
type nfs4 
(rw,relatime,vers=4.1,rsize=65536,wsize=65536,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,local_lock=none)

it should work only if forced option vers=4.2 ?
I thought it's implemented as feature to older version, not 4.2, there is few 
info about this.

[ovirt-users] NFS and pass discards\unmap question

[Sergey Kulikov]

I've upgraded to 4.1 release, it have great feature "Pass discards", that now 
can be used without vdsm hooks,
After upgrade I've tested it with NFS 4.1 storage, exported from netapp, but 
unfortunately found out, that
it's not working, after some investigation, I've found, that NFS 
implementation(even 4.1) in Centos 7
doesn't support sparse files and fallocate(FALLOC_FL_PUNCH_HOLE), that quemu 
uses for file storage, it was
added only in kernel 3.18, and sparse files is also announced feature of 
upcoming NFS4.2,
sparsify also not working on this data domains(runs, but nothing happens).

This test also shows, that FALLOC_FL_PUNCH_HOLE not working, it was executed on 
centos ovirt host with mounted nfs share:
# truncate -s 1024 test1
# fallocate -p -o 0 -l 1024 test1
fallocate: keep size mode (-n option) unsupported

Is there any plans to backport this feature to node-ng, or centos? or we should 
wait for RHEL 8?
NFS is more and more popular, so discards is VERY useful feature.
I'm also planning to test fallocate on latest fedora with 4.x kernel and 
mounted nfs.

Thanks for your work!
