Help with new installation. Accounts and LAGG

[smic717394]

Hi guys, I'm new to Truenas and I need a bit of help, maybe some of the questions were already asked, if so I apologies. My new nas is a Mini ITX A1SRI-2558 motherboard with 16GB ram and 4x 4GB WD hdd. I got most of the stuff working, but I have few questions.

1. When creating an account under home directory, if I select the pool, then a new folder will be created with the name of the user, this folder will not appear under pools or datasets and can only be deleted by deleting the username. Is it recommended to create folders for users this way or leave on nonexistent and create a dataset?

2. The motherboard have 1x 1G LAN and 1 for IPMI, I tried LAG, but I cant get LACP to work, I created a LAGG on the switch (TL-SG1016DE) but there is no option for LACP, I guess is just passive LAG, so this is a no go. I got to work the LAG as loadbalance and the failover.

I see there are 2 more opcions, roundrobin and none. The loadbalance works ok, but on failover I get access locally, but I tried to ping google.com and it fails. What option if any of LAG you recommend.

Thank you.

The motherboard have 1x 1G LAN and 1 for IPMI,

Usually, you can't use the IPMI interface as a NIC for system traffic, so LAGG or LACP is off the table. (and sounds like you don't have the right switch for it anyway... even if there was a reason to do it, which there probably isn't).

Hi, sorry, my mistake, the motherboard has 4 1GB lan ports and 1 por IPMI

OK, so you have 4 NICs (1GB each).

What are you expecting from LAGG?

 

[smic717394]

to increase the bandwidth from 1gb to 4gb

to increase the bandwidth from 1gb to 4gb

LAGG won't do that. It will increase your bandwidth up to 4x1Gbps (which is NOT the same thing as 4Gbps). A single connection will never be able to get more than 1Gbps, which is a finer point often missed by people who aren't networking nerds.

Resource - LACP ... friend or foe?

Too many LACP discussions lately. Here's what you need to know. 1) Link aggregation groups are an interesting way to boost network throughput. They're typically managed by a protocol called Link Aggregation Control Protocol (LACP). Link...

On a dumb switch, you CANNOT configure the TrueNAS side for LACP, which is a protocol that expects to be able to chat with the switch in order to manage the connection, and a dumb switch will be LACP-mute. You WILL be able to do failover, and loadbalance may work as well, and while you CAN do roundrobin, this will violate packet ordering and usually kills performance in weird and hard-to-debug ways unless you happen to love deciphering Wireshark or tcpdump packet captures. People think that roundrobin is the magic way to get that 4Gbps single link that they really want.

In reality, it all kinda sucks, and I typically recommend that if you want faster-than-1G, the place to look is at 10G, which is nice and pleasant if you follow the 10 Gig Networking Primer guidance.

Ok, thank you. I´ll have a look. My switch can do static LAG just not LACP, I´m now using loadbalance, I don't know if its any better than just one 1G connection.
Thank you all for replying. If any can clarify the account folder as well I will appreciate it.

I´m now using loadbalance, I don't know if its any better than just one 1G connection.

Only if you have two separate clients and they happen to have the good fortune to be mapped to different LAG members. See the linked article.

You really shouldn't select the pool root for any kind of share... create and share a dataset.

Home directories don't need to be their own datasets (which would only make sense if you needed a different recordsize or a different snapshot frequency per user... or a few other things, but I'm too lazy to list them all).

You don't need to delete a user to delete a directory.
