Hi All, I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting,

...ely I wasn''t able to port it to FreeBSD, it was just too much work. I''m afraid it is too Solaris-specific. My tests are quite different on the other hand, so we will just end up with more tests for ZFS, which is a good thing.) For now I''ve around 2000 tests covering only zpool create/add/remove/offline commands. I discovered some issues already, so I''ll share them while I''m working on the rest. 1. Inconsistent behaviour for ''zpool create'' and ''zpool add'' when handling mirror vdevs and log mirror vdevs. Differe...

Hi, LUN is connected to solaris 10u9 from NETAP FAS2020a with ISCSI. I''m changing LUN size on netapp and solaris format see new value but zpool still have old value.

I''ve got a zpool that has 4 raidz2 vdevs each with 4 disks (750GB), plus 4 spares. At one point 2 disks failed (in different vdevs). The message in /var/adm/messages for the disks were ''device busy too long''. Then SMF printed this message: Nov 23 04:23:51 x.x.com EVENT-TIME: Fri Nov 23 04:23:51 E...

Hi, once I created a zpool of single vdevs not using mirroring of any kind. Now I wonder if it''s possible to add vdevs and mirror the currently existing ones. Thanks, budy -- This message posted from opensolaris.org

...el, another one (though minor, I suppose) bug report: while playing with my poor pool, I tried to interact with it on -current, thus importing it with -f (without upgrading, of course). After reverting to RELENG_7, I found I no more can access history: root@moose:~# /usr/obj/usr/src/cddl/sbin/zpool/zpool history History for 'm': 2008-10-14.23:04:28 zpool create m raidz ad4h ad6h ad8h ad10h ad12h 2008-10-14.23:04:57 zfs set mountpoint=/mnt m 2008-10-14.23:05:27 zfs create m/usr 2008-10-14.23:05:29 zfs create m/usr/local 2008-10-14.23:05:32 zfs create m/usr/ports 2008-10-14.23:05:34 zf...

Folks, How can I find out zpool id without using zpool import? zpool list and zpool status does not have option as of Solaris 10U5.. Any back door to grab this property will be helpful. Thank you Ajay

I''m having following issue .. i import the zpool and it shows pool imported correctly but after few seconds when i issue command zpool list .. it does not show any pool and when again i try to import it says device is missing in pool .. what could be the reason for this .. and yes this all started after i upgraded the powerpath abcxxxx # zpoo...

Hi, one quick&dirty way of backing up a pool that is a mirror of two devices is to zpool attach a third one, wait for the resilvering to finish, then zpool detach it again. The third device then can be used as a poor man''s simple backup. Has anybody tried it yet with a striped mirror? What if the pool is composed out of two mirrors? Can I attach devices to both mirrors, let...

Hi, I wanted to add a disk to the tank pool to create a mirror. I accidentally used zpool add ? instead of zpool attach ? and now the disk is added. Is there a way to remove the disk without loosing data? Or maybe change it to mirror? Thanks, Martijn -- This message posted from opensolaris.org

Hi everyone, Just wanted to tell you a little story. We''ve been enthusiastic puppet users since about a year ago here at the Geographic Institute of the University of Zürich. But we won''t use the zpool type ever again. Its just not worth it. Here''s what happened: . one of our servers lost knowledge about one of its zfs pools . puppet didn''t find the pool and .. went on to zpool create it . we did indeed have a backup, but would have lost all data if not Creating zpools is a m...

Hi experts, I have few issues about ZFS and virtualization: [b]Virtualization and performance[/b] When filesystem traffic occurs on a zpool containing only spindles dedicated to this zpool i/o can be distributed evenly. When the zpool is located on a lun sliced from a raid group shared by multiple systems the capability of doing i/o from this zpool will be limited. Avoiding or limiting i/o to this lun until the load from the other syst...

Hi, yesterday evening I tried to upgrade my Ultra 60 to 2009.06 from SXCE snv_98. I can''t use AI Installer because OpenPROM is version 3.27. So I built IPS from source, then created a zpool on a spare drive and installed OS 2006.06 on it To make the disk bootable I used: installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0 using the executable from my new rpool. But when I boot my new disk, I get the error "no pool_props" and the booting proc...

Zpool split is a wonderful feature and it seems to work well, and the choice of which disk got which name was perfect! But there seems to be an odd anomaly (at least with b132) . Started with c0t1d0s0 running b132 (root pool is called rpool) Attached c0t0d0s0 and waited for it to resilver Rebooted from...

Hi, I’m new here so apologies if this has been answered before. I have a box that uses ZFS for everything (ubuntu 17.04) and I want to create a libvirt pool on that. My ZFS pool is named „big" So i do: > zfs create big/zpool > virsh pool-define-as --name zpool --source-name big/zpool --type zfs > virsh pool-start zpool > virsh pool-autostart zpool > virsh pool-list > virsh vol-create-as --pool zpool --name test1 --capacity 1G > virsh vol-list zpool Everything seems to work (no error message, vol-list...

Hi, I was wondering if anyone would know if this is just an accounting-type error with the recorded "version=" stored on disk, or if there are/could-be any deeper issues with an "upgraded" zpool? I created a pool under a Sol10_x86_u3 install (11/06?), and zdb correctly reported the pool as a "version=3" pool. I reinstalled the OS with a u4 (08/07), ran zpool grade, was told I successfully upgraded from version 3 to version 4, but zdb reported "version=3". I unmoun...

I have a raidz2 pool with one disk that seems to be going bad, several errors are noted in iostat. I have an RMA for the drive, however - no I am wondering how I proceed. I need to send the drive in and then they will send me one back. If I had the drive on hand, I could do a zpool replace. Do I do a zpool offline? zpool detach? Once I get the drive back and put it in the same drive bay.. Is it just a zpool replace <device>? -- This message posted from opensolaris.org
