Is V2 the same size or a similar size as V1? Will either accommodate a Kimera Cerberus?

Hey Argentum, I saw your post where you mentioned upgrading a 10x2TB to a 10x8TB (Seagate SMR) vdev. I have 2 10x vdevs that I need to replace/upgrade and I had been looking at the Toshiba 5TB and even the 6TB drives. I was afraid of going with the 8TB drives because of the horrendous write...

Shit, I was going to say I think I might have one laying around lol. I replaced it with the 36p HP SAS Expander. Better choice.

In the same boat. 20 spinning drives in ZFS and looking to lower power consumption as well as increase flexibility. It's not easy adding 10 drives at a time on the wallet. Subbed.

Unfortunately I can't back up 20+TB of data. I have backups of about the most important 1.5TB of data. I turned the server off until I get the disks in from RMA to prevent any problems. I will report back with the answers though.

Hey all, I'm in a pickle and need some advice from the ZFS gurus. I've got 2 10 drive RAIDZ2's in my pool. 3 disks from one of the vdevs are throwing me read/write and checksum errors. I've swapped cables and ports on the HP SAS Expander to no avail. The only thing other than drives I...

Just replying because I have the same question. Spun down, my array is about 100w less of power. When I gave it a shot, clients fail to mount shares right away. Can't have this.

Thanks guys, Got everything up and running. Moved from my CM590 to a Norco 4220. Did an export on the pool, installed new hardware, then did an import once everything was up and running. I appreciate all the advice. System: Norco 4220 CPU: Athlon X4 840 RAM: 8GB DDR2-800 Mobo: Gigabyte 785GM...

Thanks for the replies guys. I will make sure to export the pool before I move it to the new machine, and then import it once I get the new machine up and running. @PigLover, What kind of problems were you having with a SAS2008 chip and older Chenbro expander on SE11? I'm running OpenIndiana...

Hello, I just picked up the Norco 4220 from Newegg for $299 + free 1.5TB HDD. I currently have 10x2TB RAIDZ2 in a couple 5bay hotswaps on a USAS2-L8i. I also have 10x1TB that I am going to put in a RAIDZ2 and add to that pool. (Eventually replacing with 3+TB) I'm gonna pick up a CK12803...

I understand that completely, and that's how I figured it worked. But Spazoid said that I don't need to replace every drive to get the added space in his previous post. That confused me a bit. Also, another question I had. If I have a 10 disk vdev of 2TB drives, and a 10 disk vdev of 1TB...

Can you explain this a little more?

Pretty insightful. Yes Pig, it suits my application just fine. As long as I won't see reduced performance due to the 1st vdev being full. I suppose if I pulled off ~2TB of data at a time to a network drive, then replace it I could get it to rebalance. Would it be of benefit to add another...

Hello, I currently have a 10 drive RAIDZ2 of 2TB drives. It is a total of 14.2TB useable, and has 1TB free. I know I shouldn't have went over the 20% free rule. Assuming I add another 10 drive RAIDZ2 to the pool, will I have performance issues considering it won't re-stripe across the whole...

tdg, I'm a little confused about your post here. Assuming a 6 drive RAIDZ, the data is still striped across 6 drives because parity is striped as well. Am I wrong? Please explain. I have a 10 drive RAIDZ2 of Hitachi 512b drives. I was told 10 drives for RAIDZ2 will provide optimal...

@DeadlyOne I'd like to know cost and source as well. :)

I've recovered partitions using TestDisk numerous times.

Better than PCI for sure. PCI-e 1.1 is limited to 250MB/s per lane. (1 lane for PCI-e x1) PCI-e 2.0 is double that at 500MB/s per lane. Unless you have a large array, that should be fine. You will see speeds over 1gbps required for network transfer.

I'm interested in this as well. @Gea Also, is there a way to create a pool through the GUI with ashift=12? With most of high density consumer hdd's being 4k sectored right now, it's only going to continue... and at a rapid pace. I'd like to create my initial pool aligned for 4k, so that I...

Yea that's what I'm doing, however, in order for that to run after a reboot I have to go to the machine, and log in manually. I'd like it to auto-login for me, then I can manage it via VNC headless.

Thanks Gea, I will reset everything and give it a shot. Also, do you know if there is a way in OI to auto-login? This will run mostly headless unless I need to attach peripherals for some reason. I would like the Gnome GUI to do a few things that I'm not comfortable with in the CLI, so I...

_Gea, I'm testing out OI and napp-it in a Virtualbox install before I migrate my 20TB WHS to ZFS. I'm loving it more than ZFSGuru right now. There is so much more to it, and it helps me learn quite a bit both about ZFS and Solaris. I don't run a domain at home, but I have 2 PC's with...

I'm not as much worried about removing any of the arrays from the zpool. I was more concerned with the data risk of 3 raidz vs. 1 raidz2 or raidz3. I was thinking 5x2TB raidz, 5x1TB raidz, 5x1TB raidz. That way I can buy a few 2TB drives at a time and resilver the smaller arrays into 5x2TB...

Hello, I'm new to the forum, as well as new to ZFS. I'm not 100% sure I'm going to settle with ZFS right now, but it's definitely an option. I have 5 2TB drives, and 10 1TB drives. I'd like to eventually replace the 1TB drives with 2TB drives, but I can't really afford to just buy 10...

I'm on a Q6600 and I'm skipping. Will definitely be doing a new build come LGA2011 though.
