So, what is the story about 4KB disk sectors? Should such disks be avoided with ZFS? Or, no problem? Or, need to modify some config file before usage? -- This message posted from opensolaris.org

Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

I sent a zvol from host a, to host b, twice. Host b has two pools, one ashift=9, one ashift=12. I sent the zvol to each of the pools on b. The original source pool is ashift=9, and an old revision (2009_06 because it''s still running xen). I sent it twice, because something strange happened on the first send, to the ashift=12 pool. "zfs list -o space" showed figures at

zdb -C shows an shift value on each vdev in my pool, I was just wondering if it is vdev specific, or pool wide. Google didn''t seem to know. I''m considering a mixed pool with some "advanced format" (4KB sector) drives, and some normal 512B sector drives, and was wondering if the ashift can be set per vdev, or only per pool. Theoretically, this would save me some size on

Hello all, I have an oi_148a PC with a single root disk, and since recently it fails to boot - hangs after the copyright message whenever I use any of my GRUB menu options. Booting with an oi_148a LiveUSB I had around since installation, I ran some zdb traversals over the rpool and zpool import attempts. The imports fail by running the kernel out of RAM (as recently discussed in the list with

.. evidently doesn''t work. GRUB reboots the machine moments after loading stage2, and doesn''t recognise the fstype when examining the disk loaded from an alernate source. This is with SX-151. Here''s hoping a future version (with grub2?) resolves this, as well as lets us boot from raidz. Just a note for the archives in case it helps someone else get back the afternoon

I have some questions about the choice of SSDs to use for ZIL and L2ARC. I''m trying to build an OpenSolaris iSCSI SAN out of a whitebox system, which is intended to be used as a backup SAN during storage migration, so it''s built on a tight budget. The system currently has 4GB RAM, 3GHz Core2-Quad and 8x 500GB WD REII SATA HDDs attached to an Areca 8port ARC-1220 controller

Hello all, I found this dialog on the zfs-devel at zfsonlinux.org list, and I''d like someone to confirm-or-reject the discussed statement. Paraphrasing in my words and understanding: "Labels, including Uberblock rings, are fixed 256KB in size each, of which 128KB is the UB ring. Normally there is 1KB of data in one UB, which gives 128 TXGs to rollback to. When ashift=12 is

Well this is a new one.... Illumos/Openindiana let me add a device as a hot spare that evidently has a different sector alignment than all of the other drives in the array. So now I''m at the point that I /need/ a hot spare and it doesn''t look like I have it. And, worse, the other spares I have are all the same model as said hot spare. Is there anything I can do with this or

Hello, Daniel, Apparently your data is represented by rather small files (thus many small data blocks), so proportion of metadata is relatively high, and your<4k blocks are now using at least 4k disk space. For data with small blocks (a 4k volume on an ashift=12 pool) I saw metadata use up most of my drive - becoming equal to data size. Just for the sake of completeness, I brought up a

Hi. Is the problem with ZFS supporting 4k sectors or is the problem mixing 512 byte and 4k sector disks in one pool, or something else? I have seen alot of discussion on the 4k issue but I haven''t understood what the actual problem ZFS has with 4k sectors is. It''s getting harder and harder to find large disks with 512 byte sectors so what should we do? TIA...

If I want to use a batch of new Seagate 3TB Barracudas with Solaris 11, will zpool let me create a new pool with ashift=12 out of the box or will I need to play around with a patched zpool binary (or the iSCSI loopback)? -- Dave Pooser Manager of Information Services Alford Media http://www.alfordmedia.com

Hi Team, I need to develop Visual VoiceMail solution. In this solution I need a IMAP4 server, from which I can get a hit for each mail retrieval.

Hi, my oi151 based home NAS is approaching a frightening "drive space" level. Right now the data volume is a 4*1TB Raid-Z1, 3 1/2" local disks individually connected to an 8 port LSI 6Gbit controller. So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks and be happy. This was my original approach. However I am totally unclear about the 512b vs 4Kb issue.

Hello all, I am thinking about a new laptop. I see that there are a number of higher-performance models (incidenatlly, they are also marketed as "gamer" ones) which offer two SATA 2.5" bays and an SD flash card slot. Vendors usually position the two-HDD bay part as either "get lots of capacity with RAID0 over two HDDs, or get some capacity and some performance by mixing one

Are there any drawbacks to partition a SSD in two parts and use L2ARC on one partition, and ZIL on the other? Any thoughts? -- This message posted from opensolaris.org
