Seconded, provided it would allow to aggregate several links bandwidth for a single tcp connection... This would be very nice for links aggregation and Failover of drbd connections over 2+ GbEth paths Think I had already posted this, so thanks for debunking ;-) Envoyé de mon A0001 en...

It would have needed to be EthoIB to support VLANs ?! Could MPTCP offer an alternative http://www.multipath-tcp.org ? About it, Could it be used to aggregate several 1gbps links throughput for a single tcp connexion like for a drbd resource ? Thx for your insights

@jinger about switch failure... had 2 switch death only in the last 6 month (and at the same client !). Sh@#€%& happens man, deal with it or you'll be bitten hard. About improving network path load balancing and redundancy... couldn't Multipath TCP offer a good alternative to Ethernet LAGs ...

And when you have several sources configured, use `apt-cache policy <pkgname>` to see the available versions of a package. Then, once you begin cherrypicking from different repos, you may want to configure repos priority and package pinning to secure your upgrades

Thank you, Will investigate this further ...

New tech for me too... thank u very much for sharing this experience with us all ! My question is: is a switch needed or can crossover/back to back links be created between a pair of servers ?

That being said, can Ceph be setup and work reliably on one node ? Because in this case the config would a t least be ready for scaling and HA. Bests

Hi, Very interesting thread ! Point cleared, thanks ! So in any configuration with storage subsystems providing more than 300MB/s, 10GbEth link is _mandatory_ for DRBD if you don't want the network to be the bottleneck !? Now I'm thinking of distributing my DRBD links on several [2|3]xGb...

Hi snowman66, Thanks for your answer. Will try that but have to restart the VMs :( [EDIT] BTW, I don't see the point of linking the guest cache setting to the host one ? Bests

Hi, Could not agree more with e100, automation (techniques) and DevOps (culture) are such a thrill ! AFAIC, my toys would be called Ansible or Saltstack. My 2cts Bests

Hi, I'm also facing it on 3 W2008R2 VMs (using virtio 1.65) :-( Bests

Hi 'moxers, I have a pair of HP ML350 G6 servers with LSI MegaRAID 9266-4i+CacheVault driving Supermicro CSE836E16 enclosures via SAS bracket, filled with WD RE 3TB SATA drives. On these are configured a RAID10 array with one big virtual/logical drive with write caching and read-ahead...

I'd be ! Integration with automatic provisionning and configuration management solutions is surely on of the next areas of improvement in PVE ecosystem.

It is indeed ! Would you tell us how you configured your RAID ? Single Array on each node ? Which level ? Only made introductory readings about Ceph but as I understood it, one of it strength seems also to provide the redundancy feature instead of dedicated HW controlers (but doesn't replace...

Hi, Could you please give us example(s) of advanced routing and vlans troubles one could face ? Does this depends directly on the subnet mask (like initialization made from the start for 65k devices), or on the real effective number of devices on the network ? Thank you in advance for your...
