Hi Mark,

Take a look here:

I really wanted to use apache guacamole for that.

Assunto: [PVE-User] Loadbalancing SPICE

Hi,

We deliver customers their own Proxmox cluster and decided to do that
IPv6-only, behind an IPv4-enabled HAProxy setup. This all works well,
the webinterface functions as expected, NoVNC nicely switches along with
migrations, not an issue. Until a customer wanted to use SPICE.

I've been looking into SPICE and what I can configure for it, and it
seems that it is like HTTP, but nog suitable for vhosting. But I'm no
expert on SPICE, and I expect that there are people on this list that
know much more about it.

Has anyone succeeded in loadbalancing SPICE, or does anybody know what I
should change in Proxmox settings to make this possible?

Thanks!

Re: [PVE-User] can´t login in PVE with Linux realm in 5.3

[Jean R. Franco]

Hi Miguel,

This is something that happens even if you reboot the host?
If you cannot reboot, make sure pveproxy is running:

/etc/init.d/pveproxy status

   Loaded: loaded (/lib/systemd/system/pveproxy.service; enabled; vendor 
preset: enabled)

Hth,

Assunto: [PVE-User] can´t login in PVE with Linux realm in 5.3

Dear all,

   I have been playing with this new Proxmox 5.3 server for more than a
week before I migrate all VMs from a 5.1 server and I have been able to
log in the GUI at 8006 port with no issue. Suddenly this morning after
being able to log in with no issue I keep on getting Connection error
401: permission denied - invalid PVE ticket.

  If I check the logs I see the auth works:

Dec 22 11:53:52 node1 pvedaemon[10764]:  successful auth for
user 'root@pam'

 I made sure that system time is right too. I am not using ntp (as I am
not doing with the legacy server)

 google search is not helping either.

 I have tried to recreate the certs with pvecm updatecerts -f

 Any suggestions?

Re: [PVE-User] Local XFS storage pool - Fragmentation issues

[Jean R. Franco]

Hi Markos,

Take a look /proc/slabinfo to see if xfs_inode is using all your memory.

Please post your pve version with:
pveversion -v

Thanks,

Assunto: [PVE-User] Local XFS storage pool - Fragmentation issues

Hello List,

My use case, is to provide a large hardware-RAID backed volume (hence no
ZFS) to PVE for continuous decent performance writes by a running container
(cctv dvr).

I  have 6 x 6TB SATA drives on a hardware RAID 10 configuration.

It 's formated as a ~10TB XFS device:

/dev/sdb on /10TB type xfs (rw,relatime,attr2,inode64,noquota)

I created a local directory storage pool on my PVE host and assigned a
9.8TB mount point  to a running container (DVR)

pve:/10TB/images/101# ls -lah /10TB/images/101/
total 6.3T
drwxr- 2 root root   30 Feb 15  2017 .
drwxr-xr-x 4 root root   38 Feb 15  2017 ..
-rw-r- 1 root root 9.8T Oct 18 14:03 vm-101-disk-1.raw

After a couple of months, I started receiving the following XFS errors on
the host:

Oct 17 06:26:09 pve kernel: [5629844.259800] XFS: loop0(28500) possible
memory allocation deadlock size 72832 in kmem_alloc (mode:0x2400240)

leaving me with an unusable filesystem from inside the container (no
writes),  unless I drop the host's page cache:

echo 1 > /proc/sys/vm/drop_caches

or even need to drop all pagecache, dentries and inodes:

echo 3 > /proc/sys/vm/drop_caches (remember to sync first!)

After research, I concluded that the deadlock is caused from heavy
fragmentation on the XFS image file which has 1.2 million extends (!)
according to xfs_bmap.

Of course, there is no way to defrag this filesystem with xfs_fsr, as the
volume file occupies almost 100% of its space (yes, I won't use more than
80%). Also it wouldn't be practical to do so, as the volume is busy 24/7
(cctv recording) and the available capacity matters.

Please correct me if I am wrong, but the above seemed to be a reasonably
decent layout to employ a local XFS filesystem (which is supposed to have
better handling of large files than EXT4) under PVE. But in practice it's
not! Am I missing something?

Is LVM a more suitable solution?

Any ideas or suggestions would be greatly appreciated.

Thanks,

Markos

To rule out first a possible  GUI problem:

the whole list ?

pvesh get cluster/config/nodes

I've done via windows full backup and restore in the past.


Use bog std hardware in the VM - IDE Drive, Intel network adaptor etc.

This is because you have a different fs with this new version. 
You´ll have to modify the VM´s hard disk cache parameter, and change it to

changeing the cache parameter did not work out. Most of the stopped VMs does

Do you have any other hints on this ?
