similar to: Will "de-duplication" be added?

Suppose I have a storage server that runs ZFS, presumably providing file (NFS) and/or block (iSCSI, FC) services to other machines that are running Solaris. Some of the use will be for LDoms and zones[1], which would create zpools on top of zfs (fs or zvol). I have concerns about variable block sizes and the implications for performance. 1.

Hi gurus, I like zpool iostat and I like system monitoring, so I setup a script within sma to let me get the zpool iostat figures through snmp. The problem is that as zpool iostat is only run once for each snmp query, it always reports a static set of figures, like so: root at exodus:snmp # zpool iostat -v capacity operations bandwidth pool used avail read

I believe that I have incorporated all of the feedback given (thanks!). Changes since the 2008-11-16 version include: - ksh style & coding standards compliance in test script (Roland) - "dof_init_debug == B_FALSE" vs. "!dof_init_debug" (Adam) The updated webrev is at: http://cr.opensolaris.org/~mgerdts/6750659-2008-12-03/ -- Mike Gerdts http://mgerdts.blogspot.com/

People might find this entertaining and/or useful: http://www.gnu.org/manual/autoconf-2.52/html_chapter/autoconf_10.html With the help of Jos Backus I just discovered the answer to http://lists.samba.org/pipermail/rsync-cvs/2002-January/001271.html is that Sun's test(1) is breathtakingly broken when passed a dangling symlink: $ ln -s /nowhere bad $ ls -l bad lrwxrwxrwx 1 josb

I am pretty new to Dtrace but use the Dtrace Toolkit when trying to troubleshoot I/O issues On Oracle. I am looking for help on how to do the following: I am trying to answer whether adding more HBA Cards/ports would be effective. To do this, I need to know the i/o''s per second As well as total bandwidth per second. Has anyone done this before? Does anyone have any other ideas on how

Short question: I''m curious as to how ZFS manages space (free and used) and how its usage interacts with thin provisioning provided by HDS arrays. Is there any effort to minimize the number of provisioned disk blocks that get writes so as to not negate any space benefits that thin provisioning may give? Background & more detailed questions: In Jeff Bonwick''s blog[1], he

Is there any update/work-around/patch/etc as of the S10u4 WOS for the bugs that existed with respect to LU, Zones, and ZFS? More specifically, the following: 6359924 live upgrade needs to include support for zfs I can''t even find that bug ID on bugs.opensolaris.org (or via sunsolve when I''m logged in for that matter) anymore. Basically, one couldn''t put zoneroot on

Today, I ran a scrub on my rootFS pool.

My system (a laptop with ZFS root and boot, SNV 64A) on which I was trying Opensolaris now has the zpool-related kernel panic reboot loop. Booting into failsafe mode or another solaris installation and attempting: ''zpool import -F rootpool'' results in a kernel panic and reboot. A search shows this type of kernel panic has been discussed on this forum over the last year.

I just received a special offer from Sun (marketing...) promising that I will learn "How to use ZFS snapshots for backup and restore purposes." The relevant doc is at... https://www.sun.com/offers/docs/zfs_snapshots.pdf It says: === Begin quote === Archiving and Restoring Snapshots Another use of snapshots is to create archives for long-term storage elsewhere. In the following

I wanted to send out status on the effort to make a version of Solaris install available that supports zfs as a root file system. I''ve got a version of it ready for distribution, but I''d like to test it on the Build 62 community release before I make it available. Without the build 62 community release, I have to test it on a build 61 image, updated with some build 62 packages.

Before I open a new case with Sun, I am wondering if anyone has seen this kernel panic before? It happened on an X4500 running Sol10U3 while it was receiving incremental snapshot updates. Thanks.

Hi Folks.. I have/had a zpool containing one filesystem. I had to change my hostid and needed to import my pool, (I''ve done his OK in the past). After the import the mount of my filesystem failed. # zpool import homespool cannot mount ''homespool/homes'': mountpoint or dataset is busy The data seems it might still exist, (correct amount of used space is reported),

Hi! My name is Markus and I living in germany. I''m new to this list and I have a simple question related to zfs. My favorite operating system is FreeBSD and I''m very happy to use zfs on them. It''s possible to enhance the properties in the current source tree with an entry like "protected"? I find it seems not to be difficult but I''m not an
