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>

Hi List, First of all: S10u4 120011-14 So I have the weird situation. Earlier this week, I finally mirrored up two iSCSI based pools. I had been wanting to do this for some time, because the availability of the data in these pools is important. One pool mirrored just fine, but the other pool is another story. First lesson (I think) is you should scrub your pools, at least those backed by

Hi, I read some articles on solarisinternals.com like "ZFS_Evil_Tuning_Guide" on http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide . They clearly suggest to disable cache flush http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#FLUSH . It seems to be the only serious article on the net about this subject. Could someone here state on this

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

My server runs S10u5. All slices are UFS. I run a couple of sparse zones on a seperate slice mounted on /zones. When S10u6 comes out booting of ZFS will become possible. That is great news. However, will it be possible to have those zones I run now too? I always understood ZFS and root zones are difficult. I hope to be able to change all FS to ZFS, including the space for the sparse zones. Does

Hi, I''m running SunOS Release 5.10 Version Generic_118855-36 64-bit and in [b]/etc/system[/b] I put: [b]set zfs:zfs_nocacheflush = 1[/b] And after rebooting, I get the message: [b]sorry, variable ''zfs_nocacheflush'' is not defined in the ''zfs'' module[/b] So is this variable not available in the Solaris kernel? I''m getting really poor

This may not be a ZFS issue, so please bear with me! I have 4 internal drives that I have striped/mirrored with ZFS and have an application server which is reading/writing to hundreds of thousands of files on it, thousands of files @ a time. If 1 client uses the app server, the transaction (reading/writing to ~80 files) takes about 200 ms. If I have about 80 clients attempting it @ once, it can

Greetings, Last April, in this discussion... http://www.opensolaris.org/jive/thread.jspa?messageID=143517 ...we never found out how (or if) the Sun 6120 (T4) array can be configured to ignore cache flush (sync-cache) requests from hosts. We''re about to reconfigure a 6120 here for use with ZFS (S10U4), and the evil tuneable zfs_nocacheflush is not going to serve us well (there is a ZFS

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

I''ve got a server that freezes when I run a zpool scrub from cron. Zpool scrub runs fine from the command line, no errors. The freeze happens within 30 seconds of the zpool scrub happening. The one core dump I succeeded in taking showed an arccache eating up all the ram. The server''s running Solaris 10 u3, kernel patch 127727-11 but it''s been patched and seems to have

Hello, We have a S10U5 server sharing with zfs sharing up NFS shares. While using the nfs mount for a log destination for syslog for 20 or so busy mail servers we have noticed that the throughput becomes severly degraded shortly. I have tried disabling the zil, turning off cache flushing and I have not seen any changes in performance. The servers are only pushing about 1MB/s of constant

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

If it''s of interest, I''ve written up some articles on my experiences of building a ZFS NAS box which you can read here: http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/ I used CIFS to share the filesystems, but it will be a simple matter to use NFS instead: issue the command ''zfs set sharenfs=on pool/filesystem'' instead of ''zfs set

We are looking for a replacement enterprise file system to handle storage needs for our campus. For the past 10 years, we have been happily using DFS (the distributed file system component of DCE), but unfortunately IBM killed off that product and we have been running without support for over a year now. We have looked at a variety of possible options, none of which have proven fruitful. We are

I need some clarification on the FOID handed to zil_commit. I wrote a dscript to watch entry and return of zil_commit_writer. Here is an example output: <pre> 2009 Jan 23 23:34:36: ZIL Commit : Seq 183211310 : FOID 129644 Completed in 0 ms 2009 Jan 23 23:34:36: ZIL Commit : Seq 183211324 : FOID 129644 Completed in 0 ms 2009 Jan 23 23:34:36: ZIL Commit : Seq 183211386

Are there any drawbacks to partition a SSD in two parts and use L2ARC on one partition, and ZIL on the other? Any thoughts? -- This message posted from opensolaris.org
