Re: [PVE-User] I try hard but...

[Gilberto Nunes]

Luck!!!

Not so far!

Last night, I let running imapsync command. The command ran ok, and
finished at 22hs22 ( I saw the log today at morning!).
I went to sleep and when I woke up this morning, the VM just was stopped!
Uptime from Proxmox show me 18:28 hours.
My storage show me an uptime of 3 days.
Looking for a clue, I found in rrd graphic, that there is a lack of 2
hours, between 4 o'clock AM and 6 o'clock AM, just the period when VM stop
and don't go online again.

6 o'clock was the hour when I bring back vm online

There no HA enabled to this VM. There is just one VM. No cluster.
I was installed HA and Cluster previously in this server, but I turn it
down!

At least, there is no IO error at this time. This issue seem that was
solved.
But, really! I'm tired!!!

I do not know what to do, now!

What I must looking for???

I drop out nfs server and install GlusterFS.

My servers is not any regular machines! It is Dell R430... All those
machines are very good machines...

For God sake!!!

That's precisely my scenario...
I have DRBD + OCFS and a gigaethernet cable link the two server.
The server with DRBD + OCFS has NFS with ubuntu 14.

Disk is virtio, alright!
Because I need live migration and HA.
With IDE/SATA there is no way to do that, AFAIK!

 Well friends...

 I really try hard to work with PVE, but is a pain in the ass...
 Nothing seems to work..
 I deploy Ubuntu with NFS storage connected through direct cable ( 1 gb
 ) and beside follow all docs available in the wiki and internet, one single
 VM continue to crash over and over again...

 So I realise that is time to say good bye to Proxmox...

 Live long and prosper...

Re: [PVE-User] I try hard but...

[Gerald Brandt]

I use NFSv4, and I've never had any problems.  You have to hand modify 
the storage config file.  I've used Ubuntu NFS servers with DRBD, and 
more recently, Synology boxes (again with DRBD).  I also bond my network 
links for 2GB bandwidth.


I'm not sure why Proxmox doesn't support NFSv4 out of the box.

Rectify is wise. Do not blame Proxmox for every bad
thing that happens to you with it. You must have
patience with things that come from the world of Open
Source.

Re: [PVE-User] I try hard but...

I didn't use OCFS, eithet XFS or EXT4.  No need for OCFS unless you're 
dual primary.


Maybe OCFS is doing something weird for you?

It could be, but it could be also that with IDE or SATA the performance is
not the same as well with Virtio, or am I wrong???

Even with local storage? I thought that was one of the limitations of a node

At least as of ~v3.4, you can live migrate IDE but not SATA.  I've run 
into this a few times myself when I configured SATA CD-ROMs for some reason.

Wow! I thought that was MB/s at first, but 1.3GB/s is pretty impressive.
Are you using writback caching with the VM?

Have you tried with conv=fdatasync and oflag=dsync?

 Rectify is wise. Do not blame Proxmox for every bad thing that happens
 to you with it. You must have patience with things that come from the world
 of Open Source.

Is that something that you can easily reproduce  ? ( dd with conv=fsync
or other tool)

I do have heard about transient problems from NFS Servers at some
hosters, when running vzdump on a NFS target, the backup would hang at
some point because the NFS connection was lost.

Up to know I though this was caused by some kind of network throttling
done by the hoster, which was causing the traffic to be blocked longer
that the NFS timeout.

Hi

Should I do such command in NFS server, mounted NFS share on Proxmox or
inside the guest?

Yeah! I have some problem like this in the pass, but solved with soft
options in storage.cf

Network path is 1 gb cable. There's nothing more between storage and
proxmox.
In NFS server, no log indicate any time out, even in proxmox server. Just
isnside the VM and this happen when I open multiple impasync comand (3 at
least) in other mail host, in order to sync mailbox over the network.

Re: [PVE-User] I try hard but...

[Gilberto Nunes]

Admin or whatever is your name... I have more than 10 years deal with Unix
Linux and Windows.
I know what I done.
To the others: Yes! Should be straightforward any way...
Proxmox server is a PowerEdge R430 with 32 GB of memory.
Storage is the same server.
Both with SAS hard driver.
Between this servers there's a cable in order to provide a gigaethernet
link.
In second server, I have ubuntu 15.04 installed with DRBD and OCFS mounted
in /data FS.
In the same server, I have NFS installed and server FS to Proxmox machine.
In proxmox machine I have nothing, except a VM with Ubuntu 14.04 installed,
where Zimbra Mail Server was deploy...
Inside bothe physical servers, everything is ok... NO error in disc and
everything is running smoothly.
But, INSIDE THE VM HOSTED WITH PROXMOX, many IO errors!...
This make FS corrputed in some point that make Zimbra crash!

BTW, I will return Zimbra to a physical machine right now and deploy lab
env for test purpose

Best regards

Re: [PVE-User] I try hard but...

[Eneko Lacunza]

Gilberto,

If you want help you have to provide more clear details, starting with 
PVE version used as reported by "pve-version -v". Also, I'm not able to 
fully understand you last description of your proxmox/NFS deployment.


There are many happy users of Proxmox, myself included. I won't say it 
is free of issues, but no software is either.


I have used NFS storage mostly for backups but also for demo/test 
purposes and it has worked right. I've had some issues, but all ended 
showing an error on my part.


I see you don't have a trivial setup on your NFS server, with DRBD and 
OCFS. Are you really sure that setup is working OK? Do you have other 
VMs living there?


Cheers
Eneko

Of coz. But serving virtual disks over
  gigabit ethernet is generally bad idea too.
  And stable 70 megabytes per second are much better than unstable
  100. Also I think that you don't need to limit iops, just
  throughput.

There's issue with NFS: if you try to send
  over it more than network can deal with
  (100-120 MBps for 1-gigabit), it imposes
  several-second pauses, which are being
  interpreted like hardware errors. These bursts
  may be just few seconds long to trigger issue.
  
  You can try to limit bandwidth in virtual HDD
  config to something like 60-70 MBps. This
  should be enough for 1-gigabit network.

  to iSCSI.

What's virtual HDD config? Which

  I suppose it's bad idea to run KVM machines via NFS: it may
  produce big enough delays under high loads, which may look like
  timeouts on client side.
  If you want some network storage, iSCSI can be better chiose.

  HDD config is standard... I do not

  I wonder why I have others VM, as I said
  before, with Ubuntu, CentOS, Windows 7 and
  2012, and work fine! 

Not of all have huge big files or a lot of
connections, but they stand solid!
  
  But when require a lot access and deal with
  big files, here's came the devil! The VM just
  get IO error and die before 2 or 3 days...

On both physical servers, not hight load. I
check with HTOP and TOP as well.
  
  iostat doesn't show nothing wrong.

In side the VM, a lot I/O error from time to time...
  
  IO goes high endeed, but is so expect because I am
  using imapsync to sync mails to old server to Zimbra
  Mail Server...

But I do not expect the VM die with IO errors!
  
  It's so frustrating... :(

What's virtual HDD config? Which

  I suppose it's bad idea to run KVM machines

  If you want some network storage, iSCSI can be

Greetings.


Well friends...

I really try hard to work with PVE, but is a pain in the ass...


I´m totaly not agreed with you.


Nothing seems to work..
I deploy Ubuntu with NFS storage connected through direct cable ( 1 gb )


NFS connected through 1 GbE? You asked that (bottleneck) a long time ago 
and you was obtained many responses.


and beside follow all docs available in the wiki and internet, one 
single VM continue to crash over and over again...


That crash must have a cause: HDDs, network connections, server 
hardware, etc.




So I realise that is time to say good bye to Proxmox...


Bad decision.



Live long and prosper...


For Proxmox VE? Sure. :-)

Re: [PVE-User] I try hard but...

[Gilberto Nunes]

Answer my own question: yes! There is a bug related NFS on kernel 3.13 that
is the default on Ubuntu 14.04...
I will try with kernel 3.19...
Sorry for sent this to the list...

 There's issue with NFS: if you try to send over it more than network
 can deal with (100-120 MBps for 1-gigabit), it imposes several-second
 pauses, which are being interpreted like hardware errors. These bursts may
 be just few seconds long to trigger issue.

 You can try to limit bandwidth in virtual HDD config to something like
 60-70 MBps. This should be enough for 1-gigabit network.

 But my opinion is that it's better to switch to iSCSI.

 Proxmox server is a PowerEdge R430 with 32 GB of memory.
 Storage is the same server.
 Both with SAS hard driver.
 Between this servers there's a cable in order to provide a gigaethernet
 link.
 In second server, I have ubuntu 15.04 installed with DRBD and OCFS

 In the same server, I have NFS installed and server FS to Proxmox
 machine.
 In proxmox machine I have nothing, except a VM with Ubuntu 14.04

 Inside bothe physical servers, everything is ok... NO error in disc and
 everything is running smoothly.
 But, INSIDE THE VM HOSTED WITH PROXMOX, many IO errors!...
 This make FS corrputed in some point that make Zimbra crash!

 BTW, I will return Zimbra to a physical machine right now and deploy
 lab env for test purpose

There is nothing magical about deploying Proxmox with NFS. It's supposed 
to be straightforward as it can be.


Either hire someone who can help you or go through the trouble of 
documenting your settings so that the community can help you.

Nothing seems to work..
I deploy Ubuntu with NFS storage connected through direct cable ( 1 gb ) and 
beside follow all docs available in the wiki and internet, one single VM 
continue to crash over and over again...

So I realise that is time to say good bye to Proxmox...

Live long and prosper...

Indeed, we have almost no detail to work on.

I've had no problems with NFS, but without knowing what server setup you
are using, impossible to say. If you want to rule NFS out I'd suggets
running the VM off local storage.

Actually, with random crashes my first thought would be possible RAM parity
errors. How much ram do you have? is it ECC?
