Hi list, First off: # cat /etc/release Solaris 10 6/06 s10x_u2wos_09a X86 Copyright 2006 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Assembled 09 June 2006 Here''s an (almost) disaster scenario that came to life over the past week. We have a very large zpool

I''m testing an Iscsi multipath configuration on a T2000 with two disk devices provided by a Netapp filer. Both the T2000 and the Netapp have two ethernet interfaces for Iscsi, going to separate switches on separate private networks. The scsi_vhci devices look like this in `format'': 1. c4t60A98000433469764E4A413571444B63d0 <NETAPP-LUN-0.2-50.00GB>

Is it true that Solaris 10 u4 does not have any of the nice ZIL controls that exist in the various recent Open Solaris flavors? I would like to move my ZIL to solid state storage, but I fear I can''t do it until I have another update. Heck, I would be happy to just be able to turn the ZIL off to see how my NFS on ZFS performance is effected before spending the $''s. Anyone

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have a corrupt pool, which lives on a .vdi file of a VirtualBox. IIRC the corruption (i.e. pool being not importable) was caused when I killed virtual box, because it was hung. This pool consists of a single vdev and I would really like to get some files out of that thing. So I tried running zdb, but this fails with an assertion failure:

Hi List, As a ZFS newbie, I foolishly copied my data set to the root zpool file system (a large iSCSI SAN array). Thus: # zpool create -f iscsi c4t19d0 c4t20d0 c4t21d0 c4t22d0 c4t23d0 c4t24d0 # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT iscsi 9.53T 64.5K 5.34T 0% ONLINE - # zfs set mountpoint=/mydisks/iscsi iscsi Then copied

I have a bunch of sol10U8 boxes with ZFS pools, most all raidz2 8-disk stripe. They''re all supermicro-based with retail LSI cards. I''ve noticed a tendency for things to go a little bonkers during the weekly scrub (they all scrub over the weekend), and that''s when I''ll lose a disk here and there. OK, fine, that''s sort of the point, and they''re

I have a 100gb SAN lun in a pool, been running ok for about 6 months. panicked the system this morning. system was running S10U2. In the course of troubleshooting I''ve installed the latest recommended bundle including kjp 118833-36 and zfs patch 124204-03 created as: zpool create zfspool01 /dev/dsk/emcpower0c zfs create zfspool01/nb60openv zfs set mountpoint=legacy zfspool01/nb60openv

Hi all, I''m putting together a OpenSolaris ZFS-based system and need help picking hardware.

Hello all, I have a question about what output "ZDB -dddddd" should produce in L0 DVA fields. I expected there to be one or more same-sized references to data blocks stored in top-level vdevs (one vdev #0 in my 6-disk raidz2 pool), as confirmed by the source: http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/zdb/zdb.c#sprintf_blkptr_compact And I do see that for some of my

Hello, all I''m "playing" with ZDB again on another test system, the rpool being uncompressed with 512-byte sectors.

We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs? This message posted from opensolaris.org

Not sure what the best list to send this to is right now, so I have selected a few, apologies in advance. A couple questions. First I have a physical host (call him bob) that was just installed with b134 a few days ago. I upgraded to b145 using the instructions on the Illumos wiki yesterday. The pool has been upgraded (27) and the zfs file systems have been upgraded (5). chris at bob:~# zpool

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

Hi, I''ve got an OpenSolaris 2009.06 box that will reliably panic whenever I try to import one of my pools. What''s the best practice for recovering (before I resort to nuking the pool and restoring from backup)? There are two pools on the system: rpool and tank. The rpool seems to be fine, since I can boot from a 2009.06 CD and ''zpool import -f rpool''; I can
