Hi All, I am looking at trying to understand the conceptual model of how data is grouped and partitioned within a storge pool. In looking at the on disk document that Tabriz sent out a few weeks ago I see that object sets are the grouping which ZFS uses to group objects that are related. Specifially to aid in format and layout of like objects in to a set. So, for example 1 potential object

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

In my testing, I''ve found the following error: zpool status -v pool: local state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: none requested

Hi. I''ve almost all file system functions working. I started to run some heavy file system regression tests. They work. fsx wasn''t able to break my port, but the test you can find here: http://people.freebsd.org/~kan/fsstress.tar.gz broke it. My kernel panics on this assertion (zfs_dir.c): 749: mutex_exit(&dzp->z_lock); 750: 751: error =

The example scene: I have a database with stats about each goal made by my soccer team. This database (a data frame in R) is organized in lines (goals) with a set of columns containing data about these goals (player name, tactic position, etc). For now, this database will be called "data.frame1". What I need is to feed this "data.frame1" with new information about my team

hi, i have raid1 on zfs with 2 device on pool first device died and boot from second not working... i try to get http://mfsbsd.vx.sk/ flash and load from it with zpool import http://puu.sh/2402E when i load zfs.ko and opensolaris.ko i see this message: Solaris: WARNING: Can''t open objset for zroot/var/crash Solaris: WARNING: Can''t open objset for zroot/var/crash zpool status:

Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

The time has come to review the current Contributor and Core contributor grants for ZFS. Since all of the ZFS core contributors grants are set to expire on 02-24-2009 we need to renew the members that are still contributing at core contributor levels. We should also add some new members to both Contributor and Core contributor levels. First the current list of Core contributors: Bill

Summary: If you use ZFS, do not downgrade from build 35 or later to build 34 or earlier. This putback (into Solaris Nevada build 35) introduced a backwards- compatable change to the ZFS on-disk format. Old pools will be seamlessly accessed by the new code; you do not need to do anything special. However, do *not* downgrade from build 35 or later to build 34 or earlier. If you do so, some of

Dear r-helpers, we have installation problems: Successful installation of R-0.63 base package on Solaris 2.5.1 with the SunSoft compilers f77, c version 4.2. We habe problems with the installation of further packages e.g. integrate from CRAN. R code works but the shared objects built from fortran code do not find the appropriate libs with functions like __pow_ii or __epx at runtime. We tried

Hi, I couldn't find anything about this subject from archive - are there known problems with compiling libshout2 under FreeBSD 5.1 or 4.8 (both are up to date). I downloaded libshout2 latest nightly snapshot and tried to compile it on 5.0 and then later on 4.8. Both failed (problems were mostly around sock.c, sock.h, resolver.c - redeclaring and syntax errors). Thinking that it might be a

I build two zfs filesystems using b29 (from brandz). I then re-installed solaris express b28, preserving the zfs filesystems. When I tried to "zpool import" my zfs filesystems I got a kernel panic: > debugging crash dump vmcore.0 (32-bit) from blackbird > operating system: 5.11 snv_28 (i86pc) > panic message: > ZFS: bad checksum (read on /dev/dsk/c1d0p0 off 24d5e000: zio

I''m playing around with snv_128 on one of my systems, and trying to see what kinda of benefits enabling dedup will give me. The standard practice for reprocessing data that''s already stored to add compression and now dedup seems to be a send / receive pipe similar to: zfs send -R <old fs>@snap | zfs recv -d <new fs> However, according to the man page,

I have been playing around with osol-nv-b114 version, and the ZFS user and group quotas. First of all, it is fantastic. Thank you all! (Sun, Ahrens and anyone else involved). I''m currently copying over one of the smaller user areas, and setting up their quotas, so I have yet to start large scale testing. But the initial work is very promising. (Just 90G data, 341694 accounts) Using

Hi, I want to migrate from vmware to KVM. Therefore I have installed debian stable (lenny) and create two virtual machines (KVM). Both (XP as well as Vista) running fine. After upgrading to debian testing (sqeeze) both XP-guest as well as Vista-guest didn't start anymore. Both are failing during preparation, probably because of a network-problem. I will give XP as an example: cat
