FC - ultimately no it won't. You gotta beat up on the disk a couple 3 times. Everytime I add a new disk to my array I give myself enough time to pre-clear it at least 3 times.

I need a cache drive for my backups - all 30+ tb of them a day. I will be building a server that consists of a 4c8t 64gb intel CPU - 9 8TB drives, 5 1TB cache drives and 6 1gb nics. So I'll put all the cache drives in a jbod config. 8 of the 9 data drives as data (1 cold spare) 4 of the NICS as multihoming. 1 NIC as admin 1 nic just for looking at. With a good multihoming - I'm thinking I should be able to do 24gb in a 12 hour time span. Is my math wrong? Can I multihome this thing?

Solutions are Solutions. I myself use a Sophos UTM as my router, firewall, DNS server, etc. However many people out there aren't able to do that. Quick, down & dirty solution is to use static ips.

Brother. You don't even have a parity drive listed here. It's the one drive that saves you from two.

You even look at that report?

But I'd personally be nuking any sub 3tb disks. Your parity disks are lower in rating than a data disk. Without getting a >3tb parity disk it looks like your entire array is unprotected - please correct me if I'm wrong.

It's dependent on disk space used and disk speed avail. Myself? I wouldn't worry about.

Yea you can. It'll give us a read on CPU, Drive, RAM & Network activity. Not perfect but a spot to look at.

Glad to have helped.

With file servers we're not talking about integrated chipsets. We're talking about drive controllers. Addon cards that do nothing but control the drives. Since you're using unraid can you give us a screenshot of usage while you're rebuilding parity? (system stats, cpu, network, drives and memory?) It'd help give us an approximation of what's the holdup/slowdown. Maybe wait 15/20 minutes before you take the screen shot. ***edit I mean a screenshot of systemstats plugin

I think either your NIC is dead, or we're on a dead port on the router - or the cable is shot. Swap ports on the router, see if it comes up. If it doesn't, are you able to swap the cable? If you test with a different cable and still no go. I'd be 20 bucks the NIC died. Flashing lights aren't software based - that's 100% hardware based. I get them on machines that aren't even powered on - it's a network connection saying 'hi!' *** edit Heck, boot into the bios. Your nic will flash if your in the bios, no nothing. If it's not flashing we're down to physical issues.

the eth0 broadcast in that screenshot is 0.0.0.0 on unraid can you ping itself by ip address? *** edit No lights on the back of the card?

What's your CPU usage while doing a rebuild? My initial guess is it's your SATA controller - gigabytes website doesn't even say what it is on that motherboard. I run two https://www.amazon.com/IBM-Serveraid-M1015-Controller-46M0831/dp/B0034DMSO6 on my system. Each one capable of handling 8 drives with limited CPU overhead. I did have to reflash them however.

if you could, give me the ifconfig from the terminal on the unraid server.

remove the static mappings on the router. Let the server itself say "I am THIS!" ***EDIT As long as the server proclaims it's IP is outside of the routers DHCP scope - it'll be fine. The server says I'm .100 router realizes it can only go to .75, allows the self assigned static IP to stick around

I get 105 MBs on my 3tb drives. But I'm connected to a couple of SAS cards. *** edit What mobo? Which SATA/SAS controllers?

my full network config # Generated settings: USE_DHCP="no" IPADDR="192.168.0.100" NETMASK="255.255.255.0" GATEWAY="192.168.0.250" DHCP_KEEPRESOLV="no" DNS_SERVER1="192.168.0.250" DNS_SERVER2="" DNS_SERVER3="" BONDING="no" BONDING_MODE="1"

You're correct 6.6.8.8 is because I'm stupid. I'm using one google and a verizon (huh, really? Verizon? I thought I had a level3 DNS. crap. ) Now I'm confused. Your network config is good, it's using your router as a DNS, and your network is correct... I've got USE_DHCP="no" You have USE_DHCP=no Do the quotes count do you think? Every setting/ip address on my config are in quotes. I also have BONDING="no" BONDING_MODE="1"

and try these for dns servers 6.6.8.8 and 8.8.8.8 (both google dns servers)

You are telling unraid that it's IP is 192.168.0.194 and it should use a gateway of 192.168.0.1 As I'm looking through the logs your system is grabbing a DHCP Ip address of 192.168.122.1 Do you have 2 seperate networks in your LAN? Did you keep a copy of the old config from the flash drive? Might be easier to go back and look at it that way. Do me a favor, open up a command/powershell window on your main pc and do a ipconfig >> %userprofile%\desktop\ipconfig.txt and upload that file (which will be on your desktop

The majority of failures in a SMB network are related to name resolution errors. The solution is to set your Unraid server to a static ip (such as 192.168.1.100) and when you map the drives in a windows explorer window type in \\192.168.1.100 - it should as you for authentication. Type in your username & password, click 'remember'. Once it opens you can right click on the share and 'map network drive' assign it to a local drive letter and it's mapped. Now if you're on a domain, or are using a WinS server you can avoid having to it statically, but seriously how many home users are going to have a domain/wins server? Sometimes windows gets stupid and forgets the mapping - you will then have to right click on the drive in 'my computer' and 'remove drive' ... and remap it after a reboot. SMB is pretty good - it's just it's craptastic nameresolution that sucks. Go static IP no more problems. *** edit Now if you want to be smooth, just edit the c:\windows\system32\drivers\etc\hosts .... add in your server and name, it blammo name resolution works for every windows/linux pc you fix the hosts on .... little more of a pita on a firestick tho.

Your NIC starts. Goes Promiscious Uses a 1536 MTU Gets a IP of 192.168.122.1 Sets itself to 192.168.122.1 Netmask of 192.168.122.1-.254 Gets a 1 hour lease time. Reads /etc/resolv.conf Uses DNS of 129.168.0.1 (which is out of the network) looks in default.addnhosts - which is like a static DNS server looks in default.hostsfile Finds nothing, can't reach network - shuts itself down. So post your flash\config\network.cfg

Now after removing CacheDirs.

I just got this on 6.5 stable, and ultimately I found out it was cachedirs causing it. I'd spike to 50% cpu usage every 2 seconds (on a 2 cpu system). As soon as I removed CacheDirs it went away.

I want to be ahead of critical SMART issue - if a disk is critical, it's already dead in my eyes. I was just looking for smarthistory. Thanks for the input guys.
