Ubuntu + ZFS instalation on USB raid
location: ubuntuforums.com - date: December 2, 2012
i have a hp microserver with 5xSata port that i want to use in a zfs raid setup under ubuntu. of course using 5 ports for hdd ileaves me no room for the os installation. So it is safe and reliable to install the os on a usb stick ( or 2 usb sticks using raid1 if posible, i havemt't checked yet if raidi is possible with sticks). we'll this help, will this be enough for my next zfs setup or i shall go with anither zfs alternative like freenas?
thanks in advance
Ubuntu ZFS on Linux and ISCI oh my!
location: ubuntuforums.com - date: October 11, 2011
So I have a configuration question that might be based on a completely faulty assumption. So if you have an idea on how this setup could work better please give me a heads up. Otherwise, here is what I am trying to do:
I have a workstaiton running 10.04 LTE on a AMD Phenom II X6 1100T, 16GB of ram, 5 2TB hard drives 1 60GB ssd.
I need to use this workstation to run multiple VM's that I can later destroy. I need to have about 15TB of usable space(zfs compression) and it needs to be shared between all of the VM's. But they do not need to see each others data.
Right now I decided to use Vbox to host my VM's. I cannot use VMware because it does not support the particular hardware I have. I have 1 ssd used for actually running Ubuntu, and then I have the 5 2TB drives mounted via zfs-fuse in 1 pool with 5 different file systems. I am going to rebuild this whole zfs pool with zfs in the kernel instead of running it through fuse, but I have a few more questions.
Ubuntu ZFS Support

Can 9.10 read ZFS? I'm still using 9.04 and it can't read my Solaris hard drive which is formatted with ZFS. I'm wondering that if I upgraded maybe I could read that drive. What would be even better is if I could format the Ubuntu drive with ZFS before installing so when it was installed I could use the ZFS snapshot and pooling features like I can do on Solaris. So, I was just wondering what Ubuntu's position is on ZFS.
ubuntu zfs mount needs to be delayed?
location: linuxexchange.com - date: April 26, 2012
I have a ZFS pool that came out of a freenas box. I exported it from there and imported it into a Ubuntu 11.10 box. This has ZFS native installed (Darik Horn's ZFS PPA) which is working fine (i think). The Ubuntu system in installed on a mirrored pair of 320gb laptop drives.
When booting, I sometimes get a 'waiting for hdd warning' on boot (the volume is a copy of another active zfs volume so I dont mind if it gets trashed while I am playing).
Once I am logged in, a zpool status shows that I have corrupted data on random volumes and the recommendation to trash and rebuild. It once did a resilver when only one drive was showing errors.
If I export the volume and then import -f it, it is fine. No data corruptions and the volume is mounted ok.
Using gsmartcontrol shows that all drives in the volume have PASSED.
Are my zpool problems a sign of a hdd about to die? Or just the timing of when things are ready to be mounted. Can I delay mounting the zfs until the drives are ready?
Ubuntu + ZFS + iSCSI , does it work?
location: ubuntuforums.com - date: October 14, 2014
Hello everyone, first time posting been using Ubuntu desktop edition for a long time now though.... For starters i found out my original plans to make a file server with FreeNAS isn't going to work out due to lack of 10GB network support, so I'm considering ubuntu for this task now but would like to use the ZFS file system. I found some helpful posts that the ZFS file system works great on Ubuntu as long as it isnt for the actual install.
My plan is to install Ubuntu on a pair of raid1 SSD's for boot and then create my ZFS file system on my 28-32TB array for storage...
Heres the questions:
1. Is ZFS a good option in my situation?
2. is it in fact stable?
3. Is there a way to use RAIDZ2 if ZFS is stable and recommended
4. Does Ubuntu support iSCSI, and is it stable/recommended?
I ask a lot out of something so powerful yet free, so if anyone can make some recommendations i would greatly appreciate it
Mount ZFS (FreeNAS) volume in Ubuntu
location: ubuntuforums.com - date: June 18, 2012
I had a FreeNAS as a home server for a year. And I've collected ~450 GB of data in the last 6 months.
But I decided to move from FreeNAS to Ubuntu. The main reason of my decision is that FreeNAS doesn't support Plex media server.
I have one question - how to mount ZFS volume in Ubuntu to copy data from it and then to format it?
I've already installed zfs-fuse package and tried to mount my volume: 'zpool create OldData /dev/sdb'
It created mounting point "OldData", but 'zpool list' shows, that this mounting point has no used space. Also there are no files in /OldData.
So, how can I mount FreeNas volume in Ubuntu?

Reinstalling Ubuntu w/ZFS pool
location: ubuntuforums.com - date: February 21, 2013
Recently, I have been playing around a lot with my Ubuntu and now I would like to reinstall the OS.
I have a ZFS pool and I was wondering if I needed to take any steps in order to ensure that my pool is kept.
Do I simply recreate the mount point and perform a zpool import? Thanks in advance.
How stable is ZFS on Ubuntu?
location: ubuntuforums.com - date: January 28, 2013
I hear good things about ZFS and liked ZFS on one of my freebsd servers, but how stable is it on linux? Is it worth it or should I stick to btrfs? Which I have found to be VERY stable recently (3 months no issues on my main box, going back to ubuntu though as hardware optimization isn't really gaining anything in terms of speed and performance over ubuntu or any binary distro)
So in a nutshell, is zfs on linux or fuse stable for linux? Or should I just stick to btrfs?
