Installing and Configuring FreeNAS (Network-attached Storage) – Part 1
From the command line, type these command to check if you have or 4k sectors configured: FreeNAS™ Guide Page of zpool set cachefile=/data/zfs/elvalladolid.com tank (change tank to your pool name) zdb -U /data/zfs/elvalladolid.com | grep ashift If the answer = 9, you have byte sectors. There are 2 ways: from the console (the screen you see when you boot), and using SSH. To use the console, you will need access to the keyboard connected to FreeNAS™. Select option "9) Shell" from the menu shown in Figure a in section Initial Setup. To .

Thanks Again. ProtoSD Dedicated Sage. Joined Jul 1, Messages 3, If you make a typo or choose a bad setting you may not be able to boot and need to reflash unless you have a FreeBSD system you can connect your USB flash drive to and remove the offending setting. There is a performance thread here with a common method for testing and people posting their results.
You would probably be better to use those tests so you have results to compare to. I was told it doesn't work with freeness 8 though? You just need to remember that the changes you make need to be backed up before you do an upgrade. I definitely recommend doing some reading about it first and start out with only a few parameters so you can test your results. Looking at your configuration again, it only looks like you are using 1 harddrive, so you probably aren't using ZFS, although you do have how much is towing per mile for aaa good amount of RAM if that's what you are planning to use later.
I'll look into what u said. So will you get better performance with multiple hdd in ZFS setup? It depends on how you set them up, how many, RAM, etc. I don't think there's any real advantage to using ZFS on a single disk.
Yeh I only have one ATM just test everything what is kiosk banking service get it working the way I want to then I'm puting more in like another 1 or 2 2tb.
Which i will add to later as well. Joined May 31, Messages A single disk still gives you snapshots, data integrity, datasets with quotas and compression settings. All valuable features.
A chain is only as strong as it's weakest link If you're planning to add disks later, you'll either need to create a mirror, or move all your data off before you can properly create a raidz array which is where you'll get the most benefit from ZFS. Joined Oct 21, Messages I was told in another thread that maximum performance on the disk side is achieved when the number of disks in a set follows "the power of 2" rule.

Feb 01, · One blank CD-R / CD-RW for writing the FreeNAS ISO in preparation for the installation. Oh yeah, the bit FreeNAS ISO image itself, which you can snag here. (Version Jun 26, · To begin setting up link aggregation from the console select option #2. Then select option 3 to configure LACP as the LAGG protocol to use. Select the first interface to join to the nas, hit enter, and repeat until you have finished adding interfaces to the LAGG group. Hit ‘q’, to . Jul 23, · Just started with FreeNAS so quite new to it all. Im trying to tune my setup for better performance. My set up is: 8GB RAM 1X2TB SATA 3 HDD Intel Core 2 Duo GHz ASRock G41C-VS Motherboard OS Version: FreeBSD RELEASE-p1 FreeNas Build: FreeNASRELEASE-amd64 Also any other ways of speeding up performance would greatly be appreciated.
When I finished building my homelab recently, I at first tested several distributions but finally sticked with FreeNAS which I think has the coolest user interface, and which can be up and running in less than 10 minutes. If you're have some individual disks or and RaidZ spindle. But you can't do it for ZFS pool. You have to create a file and then export the file.
A device extent allows a raw partition volume to be exported via iSCSI. The advantage of device extent is that they are faster than file extents. The disadvantage is that the entire volume is exported. If you only want to share a portion of a volume using iSCSI, you will need to create a file extent instead.
A file extent allows you to export a portion of a volume. When creating a file extent, you specify a file name that iSCSI clients will have access to similar in concept to a mount point and the maximum size of that file storage area.
The advantage of file extents is that you can create multiple exports per volume. The disadvantage is that they are slower than device extents.
Once the target created, you must create an extent. As I mentioned before, the device extent is apparently faster, so I go for it and create a device extent. The downside is that the whole disk is exported.
Does not really matter in my case, since the disks size is only Gigs. In the example below I'm creating a device extent for the whole SSD which has got a Gigs of total storage capacity. After the Extent created, the next step is the Target-Extent association. Once this done, one last step is to activate the iSCSI service. The next step are on the VMware vSphere console. Connect to your individual ESX i server or through vCenter.
This part is actually the same as described in the Openfiler's configuration. Once validated, you'll get a prompt to rescan your iSCSI adapters. You can do so. So I went and shared that volume as an NFS share…. You can also find some Free Whitepapers to download on my Free Resources page.
Connect on: Facebook. Feel free to network via Twitter vladan. Works pretty friggin good for me. Vladan, you are the man! At first you should be able to ping the NAS box by using the command vmkping. Check the connections, activate the iSCSI initiator not active by default. Then check ESXi Firewall as well. Oh, one question. Are you using ESXi 4. Hello, Vladan. I hope this helps, Scott. Good it worked for me. I would appreciate if you can answer! Hi, Thanks for this post!
Is someone can help me? Thanks a lot, Marc. Just wanted to say thanks as this was very easy to follow and worked excellent with Freenas8 and ESXi 4.
Took me literally 3 minutes to have this up and running. Hi Vladan Did you continue using Freenas for your lab set-up, or have you changed to something else. In fact, yes, I stick with the Freenas 8 upgraded to 8. For the most part, it works pretty well, but the NAS was super slow.
At first I tried running freenas 7. It was copying data at less than 10baseT half duplex speeds. Then the same thing using freenas 8. Next I tried a physical machine with freenas 8. I did and the performance was twice as fast as when using NFS. So I ended up disabling it…. All is working well. Time to build a second white box. Thank you mate, you made my day. Thank you for your effort and sharing your knowledge with us. What kind of performance numbers are you seeing with this configuration? My Raid1 setup was not in the list.
As soon as I deleted the Raid volume I could add device extent because I could see the two drives. All has ESXi 4. On testing scenario, everything going fine and after one week of test, I implement the solution on production and it never work.
Recovery attempt is in progress and outcome will be reported shortly. Mar 15 freenas istgt: Login from iqn. Certainly not in prod. Thanks Vladan. I will continue trying some changes. If I put it to function, I post here my experiences. My experence with fileextend and deviceextend on iscsi was different. The bigger file was a vmdk with mb and mb data on it. The other file was a iso file with mb. Excellent Article. Then retraced these steps for s successful deployment. I did it with ESX 5.

Great posts by the way. Thanks in advance. This is my situation: I got two scenarios, one of testing and one of production. The ESXi lost and reestablish the connection all the time, the speed sucks, and so on.
Thanks a lot. Mexico city? Wow… cool. I hope that you enjoying to read my blog. Best regards, Vladan. I will expand it to 8gb. Next Raid will be raidz instead of raidz2. Meant to say Virtual bubble, been working on this setup for to long…. Hello Vladan hope u see this post. Glad you liked it. Even old article can sometimes help
