Has anyone else noticed a significant zfs performance deterioration when running recent opensolaris bits? My 32-bit / 768 MB Toshiba Tecra S1 notebook was able to do a full opensolaris release build in ~ 4 hours 45 minutes (gcc shadow compilation disabled; using an lzjb compressed zpool / zfs on a single notebook hdd p-ata drive). After upgrading to 2007-05-25 opensolaris release bits

Hello zfs-discuss, http://sunsolve.sun.com/search/document.do?assetkey=1-1-6604198-1 Is there a patch for S10? I thought it''s been fixed. -- Best regards, Robert mailto:rmilkowski at task.gda.pl http://milek.blogspot.com

A customer has a zpool where their spectral analysis applications create a ton (millions?) of very small files that are typically 1858 bytes in length. They''re using ZFS because UFS consistently runs out of inodes. I''m assuming that ZFS aggregates these little files into recordsize (128K?) blobs for writes. This seems to go reasonably well amazingly enough. Reads are a

Hi list, while preparing for the changed ACL/mode_t mapping semantics coming with onnv-147 [1], I discovered that in onnv-134 on my system ACLs are not inherited when aclmode is set to passthrough for the filesystem. This very much puzzles me. Example: $ uname -a SunOS os 5.11 snv_134 i86pc i386 i86pc $ pwd /Volumes/ACLs/dir1 $ zfs list | grep /Volumes rpool/Volumes 7,00G 39,7G 6,84G

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

(i use the term loosely because i know that zfs likes whole volumes better) when installing ubuntu, i got in the habit of using a separate partition for my home directory so that my data and gnome settings would all remain intact when i reinstalled or upgraded. i''m running osol 2008.11 on an ultra 20, which has only two drives. i''ve got all my data located in my home directory,

Hi. I thought I''d take a stab at the first steps of porting ZFS to Darwin. I realize there are rumors that Apple is already doing this, but my contact at Apple has yet to get back to me to verify this. In the meantime, I wanted to see how hard it would be. I started with libzfs, and promptly ran into issues with libnvpair. It wants sys/nvpair.h, but I can''t find that in the

Hello ZFS experts: I would like to study ZFS de-duplication feature. Can someone please let me know which directory/files I should be looking at? Thanks in advance. -- This message posted from opensolaris.org

Does opensolaris iSCSI target support SCSI-3 PGR reservation ? My goal is to use the iSCSI LUN created by [1] or [2] as a quorum device for a 3-node suncluster.

This is from a discussion on opensolaris-tools that is somewhat relevant for DTrace community. I wrote a simple D script (http://www.opensolaris.org/os/project/onnv/onnv_build/faster_builds/tools/dtrace/dirtrace.d) that collects data for each dmake process during the Solaris build. After that the data is post-processed by a Perl script

In another thread recursive snapshot creation was found atomic so that it is done quickly, and more important, all at once or nothing at all. Do you know if recursive destroying and renaming of snapshots are atomic too? Regards Henrik Heino

Hi all, Is there some documentation or some example on how to interpret the arg0 .. arg<n> for the aioread, aiowrite, aiowait syscalls? The system call name for all three seems to be "kaio".

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")
