• Troubleshoot broken ZFS

  - by BBK

  I have one zpool called tank in RaidZ1 with 5x1TB SATA HDDs. I'm using Ubuntu Server 11.10 Oneric, kernel 3.0.0-15-server. Installed ZFS from ppa also I'm using zfs-auto-snapshot. The ZFS file system when zfs module loaded to the kernel hangs my computer. Before it I created few new file systems: zfs create -V 10G tank/iscsi1 zfs create -V 10G…

• Oracle Solaris 11 ZFS Lab for Openworld 2012

  - by user12626122

  Preface This is the content from the Oracle Openworld 2012 ZFS lab. It was well attended - the feedback was that it was a little short - thats probably because in writing it I bacame very time-concious after the ASM/ACFS on Solaris extravaganza I ran last year which was almost too long for mortal man to finish in the 1 hour session. Enjoy.…

• Unable to install ZFS (Ubuntu 13.10)

  - by user209707

Configuration : Ubuntu 13.10 (GNU/Linux 3.12.0-rc7+ x86_64) I attempted to install ZFS native using : sudo add-apt-repository ppa:zfs-native/stable sudo apt-get update sudo apt-get…

• ZFS replication between 2 ZFS file systems

  - by XO01

  I initially replicated tank/storage1 -- usb1/storage1-slave (depicted below), and then (deliberately) destroyed the snapshot I replicated from. By doing this, did I lose the ability to incrementally (zfs send -i) replicate between these 2 file systems? What's the best way to approach SYNC'ing these file systems after destroying this…

• Booting off a ZFS root in 14.04

  - by RJVB

  I've been running a Debian derivative (LMDE) on a ZFS root for half a year now. It was created by cloning a regular ext4-based install with all the necessary packages onto a ZFS pool, chrooting into that pool and recreating a grub menu and bootloader. The system uses an ext-3 dedicated /boot partition. I would like to do the same…

• mdadm+zfs vs mdadm+lvm

  - by Alex

  This may be a naive question since I'm new to this and I cannot find any results about mdadm+zfs, but after some testing it seems it might work: The use case is a server with RAID6 for some data that is backed-up somewhat infrequently. I think I'm well served by any of ZFS or RAID6. Platform is Linux. Performance is secondary. So…

• ZFS pool broken after upgrading to 14.04 LTS

  - by cruiserparts

  Well, I have been putting off upgrading to 14.04 for fear that I would break something. Actually for fear that it would break zfs (or I would break it). I am bascially slightly better than novice at linux. Spent the last couple of hours trying to get the pool back. Now I am at the stage where I don't think I have a complete…

However, once everything installed correctly, and I tried installing another application via apt-get, I get a weird issue with my sudoers file: max@host:~$ sudo apt-get install deluge deluge-web sudo: /etc/sudoers.d/zfs is mode 0644, should be 0440 >>>…

• Reading a ZFS USB drive with Mac OS X Mountain Lion

  - by Karim Berrah

  The problem: I'm using a MacBook, mainly with Solaris 11, but something with Mac OS X (ML). The only missing thing is that Mac OS X can't read my external ZFS based USB drive, where I store all my data. So, I decided to look for a solution. Possible solution: I decided to use VirtualBox with a…

  The Previous Versions tab on the Windows desktop provides a straightforward, intuitive way for users to view or recover files from ZFS snapshots.  ZFS snapshots are read-only, point-in-time instances of a ZFS dataset, based on the same copy-on-write transactional model used throughout…

• Copying files to zfs mountpoint doesn't work - the files aren't actually copied to the other filesystem,

  - by user113904

  I have 3 x 4 TB disks in a NAS that I want to group together and access as if they were one whole 'unit' of some kind. I also have a 250GB disk containing the OS - this is full of films and tv shows currently. I thought zfs sounded good so I created a raidz zpool, after installing the ppa …

• Strange ZFS hidden filesystem problem

  - by RandomInsano

  Half of my ZFS filesystems are hidden in ZFS-fuse. Here's my story: So, I love ZFS. I used it for about six months on FreeBSD, but due to it crashing the kernel during heavy inter-filesystem IO load, I tried switching to Solaris 5.10. That was good, but when I attempted to do an import of…

  Having become disillusioned with hacking Buffalo NAS devices, I've decided to roll my own Home server. After some research, I have settled on an HP Proliant Microserver with Ubuntu Server and ZFS (OS on 1 Ext4 disk, Data on 3 RAIDZ disks). As Joel Spolsky and Geoff Atwood say with…

• ZFS Basics

  Stage 1 basics: creating a pool # zpool create $NAME $REDUNDANCY $DISK1_0..N [$REDUNDANCY $DISK2_0..N]... $NAME = name of the pool you're creating. This will also be the name of the first filesystem and, by default, be placed at the mountpoint "/$NAME" $REDUNDANCY = either mirror…

• ZFS SAS/SATA controller recommendations

  - by ewwhite

  I've been working with OpenSolaris and ZFS for 6 months, primarily on a Sun Fire x4540 and standard Dell and HP hardware. One downside to standard Perc and HP Smart Array controllers is that they do not have a true "passthrough" JBOD mode to present individual disks to ZFS. One…

• Where is the central ZFS website now?

  - by Stefan Lasiewski

  Oracle dumped OpenSolaris in Fall 2010, and it is unclear if Oracle will continue to publicly release updates to ZFS, except maybe after they release their next major version of Solaris. FreeBSD now has ZFS v28 available for testing. But where did v28 come from? I notice that…
