similar to: Why we wont use zpool ever again

Hello all, It was often asked and discussed on the list about "how to change rpool HDDs from AHCI to IDE mode" and back, with the modern routine involving reconfiguration of the BIOS, bootup from separate live media, simple import and export of the rpool, and bootup from the rpool. The documented way is to reinstall the OS upon HW changes. Both are inconvenient to say the least.

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

How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id:

I just got a call from another of our admins, as I am the resident ZFS expert, and they have opened a support case with Oracle, but I figured I''d ask here as well, as this forum often provides better, faster answers :-) We have a server (M4000) with 6 FC attached SE-3511 disk arrays (some behind a 6920 DSP engine). There are many LUNs, all about 500 GB and mirrored via ZFS. The LUNs

hello, all I am have constraint disk space (only 8GB) while running os inside vm. Now i want to add more. It is easy to add for vm but how can i update fs in os? I cannot use autoexpand because it doesn''t implemented in my system: $ uname -a SunOS sopen 5.11 snv_111b i86pc i386 i86pc If it was 171 it would be grate, right? Doing following: o added new virtual HDD (it becomes

Folks, I''m trying to figure out whether we should give ZFS / mpxio a shot on one of our research servers, or simply skip it (as we have previously). In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I''ve got an x2270 with the Sun EZ-SAS HBA and external SATA

Hello, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP.

Hello List, I have a production machine with very low ram (Xen Virtual Server) that runs mysql and lighty->pound->mongrel (2 instances). About once a day, one of the mongrels just locks up, leaving that in its log files: *** glibc detected *** /usr/bin/ruby: free(): invalid next size (fast): 0x0a744780 *** That process (mongrel) will stay locked, not answer any connections anymore and

Hi All, Its been a while since I touched zfs. Is the below still the case with zfs and hardware raid array? Do we still need to provide two luns from the hardware raid then zfs mirror those two luns? http://www.opensolaris.org/os/community/zfs/faq/#hardwareraid Thanks, Shawn -- This message posted from opensolaris.org

Hi Folks, I''m sure tons of people are gonna ruin a whole drawer of their best panties over this one. Rick Olson worked on the mongrel_upload_progress gem, documentation and examples and has almost everything you need to do progress tracked file uploads using just Mongrel to handle the upload. This means that Rails (or any other framework) isn''t blocked while the upload

We have some HDS storage that isn''t supported by mpxio, so we have to use veritas dmp to get multipathing. Whats the recommended way to use DMP storage with ZFS. I want to use DMP but get at the multipathed virtual luns at as low a level as possible to avoid using vxvm as much as possible. I figure theres no point in having overhead from 2 volume manages if we can avoid it. Has anyone

Hi list, I have tried to reach Bradley (author of mongrel_cluster) by mail, but have not gotten a response. So I''ll try trough this channel: I have ''developed''[1] a small extension to mongrel_cluster that allows selective restart of any one listener in a configuration that contains more than one listener by using a command like mongrel_rails

Hi, are there any good ways of scripting an inventory of managed resources on all nodes? I''ve found the inventory script by R.I.Pienaar ( http://www.devco.net/archives/2010/02/26/what_does_puppet_manage_on_a_node-2.php) which does what I want but only locally on each client. Is there any native way of syncing the client_yaml data centrally or any other way of doing this? I need a

It seems that a recent code cleanup broke --user and --group switch in the trunk. Mongrel essentially ignores these commands. This applies to everyone who has installed gem install mongrel --source=http://mongrel.rubyforge.org/releases/ recently. I have attached a patch to revert to some old working code. best regards, kaspar -------------- next part -------------- An embedded and
