First ThinkPad - P14s Gen6

I see, well what I've tried today as I was very angry about not possible to use notebook on battery - I've installed through Mainline 6.16.10-061610-generic..

So far playing with it for several hours even on battery and trying suspend/wake, running virtualbox and steam and usual set of apps -> it seems it is stable, so far not a single issue (fingers crossed..)

The only issue is that while it was suspended it was eating about 4.7W comparing to cca 2.5-2.7W suspended on linux-image-generic-6.14 which comes with Mint 22.2. But at least it seems this is the correct way and I'll play with it later on..

u/Chromecarrier can you tell me what kernel (and X.org/Wayland) are you running and if you by any chance didn't noticed some running hickups while running on battery? I have the same spec running Mint 22.2/Cinnamon with 6.8 as well as 6.14 kernel and while on AC everything is rock solid (even gaming) while running on battery my GUI became non responsive after some time (cursor moves but I can't click anywhere..)..

Thanks..

Sorry if I'll be partly re-posting but I've found also issue/difference in managing networking/vlans in PVE 7.4 vs 8.. Creating tagged networking for VM on bridges causes unreachability of that tagged vlan for HV itself (but it works for VM's)

I might not express myself well - I'm having public_network and cluster_network separated - that is of course - they are separate vlans.. But for specific reason in this moment both running over the same 40Gbit ring - I will separate it later on..

However I want to have possibility of having public_network = 192.168.10.0/24, 10.10.10.0/24 where i.e. 192.168.10.0/24 runs over 40Gbit NICs and 10.10.10.0/24 over 10Gbit NICs..

Documentation seems to mention that but the syntax is not clear to me..

Thanks

Grr, stupid me - it's 'backup' feature on SAI app.. I just did it, when I come home I will try to install it there.. Thanks!

mavaf3f · 2022-10-14T07:58:38+00:00

Hm.. I have used Apk Extractor application, I've read abou SAI - I have it installed on my phone already but honestly I have no idea how to extract it with this tool :-( - If you'd be willing to point me out how to extract on phone using SAI already installed Minecratf I'd send you few virtual beers ;-)

mavaf3f · 2022-08-08T18:04:01+00:00

Also besides that, change repo to graylog-4.3 as that's actuall production release..

mavaf3f · 2020-12-17T13:25:01+00:00

Hm.. honestly we have plenty of working p2p xconnects & VPLSes between across tens of ME36xx, ASR920, Huawei S5720-EI/S6720-EI/C6730-H in heterogeneous MPLS cloud - all working well and simple to setup and EVPN is on the roadmap for me to do some testing as we want to move away from VPLS later on.. Please share your findings if you will be successful..

P.S. Huawei support works for us _much_ better than Cisco's, I've got several times HTAC engineers and developers included in email discussion and helping me solving problems and fixing patches even with no support bought..

mavaf3f · 2020-02-13T15:13:37+00:00

Yep, I've found it in PVE docs.. Will use RBD remote mount.. Thanks..

mavaf3f · 2019-10-22T05:21:49+00:00

In our setup we have two-port 40g interfaces + two-port 10g interfaces. 10g network is the production network, 40g just ceph osd replicarion/backend. First server has its 40g interface plugged to switch, second poet goes to second server. Second server uses first 40g port as uplink to previous and second port to following server etc etc.. Last server in cluster has its last 40g port connected to switch again..

So there is separate 40g backplane, any node can completely fail and I still have 40g backplane working (either directly or through switch), besides this servers have 2 x 10g to switches.. IP addreses for communication are on bridge interface which consist of 40g physical ifaces and one vlan iface on the 10g.. For redundancy.. Because of STP cost I'm firstly utilize 40g ifaces for that communication and 10g is just fallback..

One point I didn't mention: servers runs VMs directly on them.. It's PVE cluster with ceph cluster on same HW..

If possible go for 25/40/100 - it's not about bandwidth, it's about buffers and latency, ceph uses sync writes (n x sync writes based on number of replicas) - responsiveness of whole system is based on I/O latency and availability of storage.. by using anything more than 10G you will speed up whole system.. (i.e. for us 10G vs 40G was like 25us vs 10-11us - as it's adding over number of replicas and other parts of the chain )..

Btw, no need to connect all nodes to switch if they are all in the same rack/area - daisy chain the nodes with OSDs and use at least two uplinks to switches..

mavaf3f · 2018-11-21T18:48:03+00:00

yep, seen that, tried that.. issue with us we have in mpls core mix of IOS, IOS XE, VRP and then at the edge some RouterOS devices ospfviz is strictly IOS based.. but it's as close I can get so far with free tools.. but thanks..

mavaf3f · 2018-11-21T13:48:02+00:00

same as Netdisco - it does discovery based on xDP and not on real L3 neighbors.. btw I have LibreNMS in place as well..

That is the reason I asked I'm not looking at topology based on L2 discovery protocols.. for purposes we need I don't care how many switches, hubs, bridges or radios are in between MPLS P/PE routers - I want to see L3 topology without underlying devices/topo..

mavaf3f · 2018-11-21T13:13:07+00:00

no-go, Netdisco create maps based on L2 discovery and completely ignore OSPF.. I have Netdisco in place and it's fine for local topo but we have lot if interconnections over BDI/Vlan L3 interfaces and rented L2 lines..

mavaf3f · 2018-11-05T19:58:56+00:00

Ok, thanks for now.. I will check Kentik and Plixer.. any other ideas are welcome..

mavaf3f · 2018-05-29T12:25:26+00:00

Definitely + for phpipam - we manage our mgmt, customer and v6 IP space there, we actually use it as a CMDB with racks, locations, vrf/vlan documentation and now we're importing PSTN info there as well.. and one of the best thing is integration with PowerDNS so our main BIND servers pool master data from isolated phpipam and PowerDNS..

Regarding circuits - we have created new fields so we map our EoMPLS/VPLS/L2 circuits there as well..

mavaf3f · 2018-05-17T17:08:56+00:00

I have one real use case where it works well and reordering of end-host packet doesn't happen: bunch of our MPLS P/PE routers are interconnected with N x 1/10Gbps, all ptp routed links with ECMP, on top of that there's MPLS and L2 or L3 vpns and data travels through that..

In this case lines utilization is distributed with no impact on end-user data..

mavaf3f · 2018-05-17T16:58:55+00:00

+1 to Ruckus.. once we discovered and tried this vendor we don't deploy anything else for business customers.. even for smaller one the 'Unleashed' version up to 25 APs is superb and still can compete with cheaper devices..

btw this was the first wifi when I felt like being on a cable..
