similar to: [storage-discuss] Preventing zpool imports on boot

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.

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.

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/

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

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

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 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.

Deduplication was committed last night by Mr. Bonwick: > Log message: > PSARC 2009/571 ZFS Deduplication Properties > 6677093 zfs should have dedup capability http://mail.opensolaris.org/pipermail/onnv-notify/2009-November/010683.html Via c0t0d0s0.org.

Does anybody know if native block level replication or block level ?de-duplication? as NetApp calls it will be added? This message posted from opensolaris.org

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.

I''m unable to boot a zone after I did a sys-unconfig, how do I recover?

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.

Hi, I''ve a b81 server running for a while. I''ve done all sorts of Python related stuff on it (nothing amazing, mostly compiled python2.5 and iPython in /usr/local), and now am trying to use it with xVM to install Windows on a virtual machine in it. I''m having trouble creating the new machine, and I get a blank error response like so when I try to do it:

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),
