comment How to set up 2 separate VLANs on one switch (HP v1910-48G switch)
@NuMeMiie Hmm... strange... the route(s) had already been there as I can see on the last screenshot (192.168.1.0/24 -> 192.168.0.241).

Please provide some details: Do you use kickstart or manual OS installation? Do you use dhcp or manual interface setup?

I am afraid this is impossible unless supported directly in config web interface. It seems this this model is not supported by third-party firmware vendors like tomato or openwrt.

@NuMeMiie It is not good practice to have parallel questions. I saw that question is hold as "off-topic" in Network Engineering. I just asked the moderator to move It to this site. If moderators will agree and do It I will continue there. Otherwise I will continue here.

comment iSCSI drive running at 100% but SAN and Network are not
Usually only sequential read/writes can saturate a storage bandwidth capacity. If a random acces pattern is presented in your workload then IOPS and latency are deciding factors.

comment Indepedent pairs of RAID 1 is superior to RAID 10
@ewwhite This question is not about RAID levels. It is as about a "RAID" vs an "Application" using multiple drives itself. I did not find an answer in serverfault.com/questions/339128/… and wonder why this question is marked as "duplicate".

Then try to make alias eth:0 and custom IP setup for It.

comment Configuring DHCP IPv4 and static IPv6 on the same interface
I guess static address is ignored since BOOTPROTO=DHCP. Why do not you make reservation for IPv6 on the same DHCP server?

comment How can I route or bridge vlan properly with linux router?
Definitely you should not bridge eth3 and eth3.42 together - these are different VLANs. I did not configure multiple SSID WiFi NIC on Lunux and do not know how It should appeared - I presume as wlan0/1/2/... . What is wlan1 in your setup, second physical NIC or just logical NIC with different SSID?

comment NFS on Btrfs on multi-devices .vs. Glusterfs on distributed-volume?
... and even more, multi-drive local filesystem like brtfs usually implies stripping, in your case - stripping over iSCSI volumes wich is generaly bad idea. GlusterFS is desined to work in such enviroment but I am afraid you will be disappointed of its performance for your load pattern. As well as I can not see any oprational benefits of OpenStack tools in this case.

I understood your point but for performance reasons It is better to keep the storage stack as simple as possible. Ideally as SvW suggests. But you need shared storage You said. Then my answer is a next approach.

Well, I do not understand the purpose of wlan0 on the router. It is already connected to vlan1 and vlan42 using eth3 wired port.
