    Has anyone compared FreeBSD ZFS vs ZFS on Linux?

    ZFS on Linux also. My home server zpool was created July 2011. Has been great. I have even moved to ZFS root pools (rpools). All the ZFS benefits, especially the snapshotting, work on my boot device now. My work computer is also a ZOL rpool mirror. Only problem with either is that you...

    SuperMicro JBOD Question

    Bought the E26 model. I was suprised to find no internal sff-8087 included to connect the front and back backblanes. This in effect made it two enclosures sharing a chassis. Since we are building an HA setup and will need to cascade, I had to order additional cables. I connected each of the...

    ZFS based storage

    I want to highlight this comment. Napp-it is not a distro. It is a frontend. It can only do what the system it is installed on can do. As dave99 suggested, OmniOS is pretty solid. Give it (and Napp-it) a try.

    ACL inheritance and ABE broke when using nested ZFS filesystems on OmniOS

    I sent this to the OmniOS discussion list, but thought I'd run it by you guys as well. I'm setting up a ZFS OmniOS storage server with SMB shares for AD authenticated group shares. I got Active Directory integration, and Access Based Enumeration to working, then focused on quotas. I...

    Will a SSD help my web browsing performance?

    No one can actually give a complete answer with the info you provided. Is your machine utilizing its swap file now? How much RAM do you have? How many background programs/services are running? The best answer to so far is, NO, will not effect your web browsing experience... after the...

    ZFS mirror across two enclosures?

    Will do. Been evaluating various ways of doing this for a while, but things are really taking shape. @all -- Thanks for the feedback. I'm glad we are thinking alike.

    Gigabyte 990fxa-ud3 what slot to put ibm 1015 in?

    I have the M1015 and the Asus P8B WS. Did a bios update and the machine failed to boot until I pulled the card. After relocated from the farthest from the CPU to the closest and it worked. Also back in the day when I crossflashed my M1015, I needed to do it in another PC because of detection...

    ZFS mirror across two enclosures?

    I'm looking at bring up an OmniOS ZFS SMB server at work for large datasets. Originally I was thinking 11x4Tb Raidz3, Mirrored ZIL, L2arc, and hotspares in an external enclosure. However, because of the IOPS boost, I am thinking that 16x4TB mirrored pairs are looking like the way to go. Then...

    ZFS N00b: raidz3 and larger qty of disks?

    Another reason raidz2/z3 is not equal to raid5/6 is that you do not resilver the entire drive, bit for bit, but you resilver just the data. Therefore, resilver times will greatly be affected by the utilized space. I know this doesn't exactly speak exactly to your question, but seems...

    M1015 to 9211-IT ...no disks detected - please help

    I think you are on the right path... either the flash or the cables. http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10254&cs_id=1025406 are the cables that work with my m1015 - IT mode.

    Storage legal question

    ZFS processor question / scenario?

    1) I'd also recommend the 1155 setup. 2) The RAM you selected is registered. Make sure you get "unbuffered" with the C20X chipset. 3) 2X8GB is a good starting point. 4) You can start with the onboard controllers, but likely you will want an add-in controller. 5) A megaraid controller is NOT...

    ZFS processor question / scenario?

    I have a feeling you are designing a lopsided box. Could you give us more of your proposed specs? Stated your processors and that you intend to use 32gb ram and 3x 2Tb Red drives. How about controllers, MB, other storage? You mentioned a C206 chipset. One of the reasons to go with that...

    Virtual Drives and ZFS

    I run Linux with ZFSonLinux as a host OS and virtualbox for my various guest OSes. I don't create giant VDI or VDMK files, but modest sized ones for booting and use the Virtualbox share folders to map to my directories on my ZFS mount. If you don't like Linux/ZOL, you could do the same with...

    Speaking of the Supermicro chasis... If I chose the CSE-847E26-RJBOD1 with dual controllers, could I use mux boards to use SATA drives instead of SAS?

    Please review DAS part list

    pjkenned, I'd love to just make a zfs server and open up a share to the existing server. If it were solely up to me, there would be doubt. I run zfs at home and just love it and I'm pretty sure it would work beautifully. I'm kinda stuck for now looking for a DAS setup. I like the Supermicro...

    WHS + 5TB + ESXi

    1) If you have raidz(1, 2, or 3) your storage continues to work, even before a replacement. However you might notice a speed reduction and you are less protected from other events. 2) Assume 5x1TB raidz , replace 1 drive with 2Tb, no new capacity will be detected... replace all 5 drives, one at...

    Recommendations for 20TB RAID 6 system

    I prefer to give people a fair explanation of advantages and the disadvantages and allowing them to make choices based on their situation. I do not scare them toward the decisions I made with inflammatory language. It will be the end-user's choice, and I will be happy if they are content with...

    Recommendations for 20TB RAID 6 system

    I think "terrible" is a bit strong.... With the current release of can't add a disk to a 5 x raidz2 and make it a 6 x raidz2, but you can add a disk at a time (5 x raidz2 + 1(no raid)) or 2 at a time (5 x raidz2 + 2 (mirror)) or even more (5 x raidz2 + 3 x raidz)... you get the idea. When you...

    My main array is ZFS on Linux (5x 2TB raidz). I have an external enclosure with 2x 3TB (raid 0) for backup. Serously consider a ZFS for your main array and backup array. If you don't want solaris or BSD, feel free to use ZFS on Linux (in development, but very stable). Get your ZFS array...

    Lots of problems =\

    That was almost a helpful response....... In order to save your data, you should create a linux live CD and boot off that. You can then transfer your data to another drive. Be sure not to move any EXE files since you stated they were infected. There MIGHT be a way to recover your existing...
