Hello Everybody 

I would like to achieve better performance by teaming NICs on the host. 

Are two 

PWLA8391GTLBLK INTEL Network Card PRO/1000 GT (10/100/1000Base-T, 1000Mbps, Bulk, Gigabit Ethernet, lowprofile PCI) NICs 
good enough to be bond in or der to get higher performance ? Switch and NAS will also be running trunked NICs 

What NICs are recomme nded for teaming in proxmox ? 

thank you very much in advance and 




srdačan pozdrav / best regards

Hello all !

I use LVM snapshot to backup, freeze and revert VM (each VM has its LVM on SAN).
But....

LVM snapshot freeze the VM at a specific time but into the VM the FS is not
consistent.
I know the modern FS use journal.. and a simple fsck solves the problem.
But... db or ms exchange do not like this treatment.
I can activate VSS into MS VM before create LVM snapshot ? Or can I set the VM
in stable state before activate it ?

The only (stable) solution I found is to shutdow the VM server, create the
snapshot LVM and immediately start it. OK, but it isn't the best solution.

Any idea ?

Very thanks

Any reasonable database use transactions, so that is not really  a problem.

We currently do not have a guest agent, so that is not possible. But this is a planned feature.
