[zfs-discuss] Migrating to ZFS

2010-06-01 Thread zfsnoob4
Hello, I currently have a raid1 array setup on Windows 7 with a pair of 1.5TB drives. I don't have enough space in any other drives to make a backup of all this data and I really don't want to copy my ~1.1 TB of files over the network anyways. What I want to do it get a third 1.5 TB drive and m

Wow thank you very much for the clear instructions. And Yes, I have another 120GB drive for the OS, separate from A, B and C. I will repartition the drive and install Solaris. Then maybe at some point I'll delete the entire drive and just install a single OS. I have a question about step 6, "S

Re: [zfs-discuss] ssd pool + ssd cache ?

2010-06-04 Thread zfsnoob4
I'm also considering adding a cheap SSD as a a cache drive. The only problem is that SSDs loose performance over time because when something is deleted, it is not actually deleted. So the next time something is written on the same blocks, it must first delete, then write. To fix this, SSDs allo

I was talking about a write cache (slog/zil I suppose). This is just a media server for home. The idea is when I copy an HD video from my camera to the network drive it is always several GBs. So if it could copy the file to the SSD first and then have it slowly copy to the normal HDs that would

I'm very excited. Throw some code up on github as soon as you are able. I'm sure there are plenty of people (me) that would like to help test it out. I've already been playing around with ZFS using zvol on Fedora 12. I would love to have a ZPL, no matter how experimental. -- This message posted

[zfs-discuss] Zpool import not working

2010-06-11 Thread zfsnoob4
Hey, I'm running some test right now before setting up my server. I'm running Nexenta Core 3.02 (RC2, based on opensolaris build 134 I believe) in Virtualbox. To do the test, I'm creating three empty files and then making a raidz mirror: mkfile -n 1g /foo mkfile -n 1g /foo1 mkfile -n 1g /foo2 T

Thanks, that works. But it only when I do a proper export first. If I export the pool then I can import with: zpool import -d / (test files are located in /) but if I destroy the pool, then I can no longer import it back, even though the files are still there. Is this normal? Thanks for your h

Thanks. As I discovered from that post, VB does not have cache flush enabled by default. Ignoreflush must be explicitly turned off. VBoxManage setextradata VMNAME "VBoxInternal/Devices/piix3ide/0/LUN#[x]/Config/IgnoreFlush" 0 where VMNAME is the name of your virtual machine. Although I tried

Thank you. The -D option works. And yes, now I feel a lot more confident about playing around with the FS. I'm planning on moving an existing raid1 NTFS setup to ZFS, but since I'm on a budget I only have three drive in total to work with. I want to make sure I know what I'm doing before I mess
