Hi all, I remember at OSCON 2005 there was talk of adding DTrace probes to PHP (in fact, I have a photo of Bryan and Wes working on it!). Did they ever get into the upstream branch, ''cause I don''t recall seeing a --enable-dtrace (or similar) configuration option when I recently built PHP 5.2.1. If not, is there an ETA? TIA, -- Rich Teer, SCSA, SCNA, SCSECA, OpenSolaris CAB

Hi all, I have a situation where I need to consolidate a few servers running Solaris 9 and 8. If the application doesn''t run natively on Solaris 10 or Nevada, I was thinking of using Solars 9 or 8 branded zones. My intent would be for the global zone to use ZFS boot/root; would I be correct in thinking that this will be OK for the branded zones? That is, they don''t care about

Hi all, I have a pool called tank/home/foo and I want to rename it to tank/home/bar. What''s the best way to do this (the zfs and zpool man pages don''t have a "rename" option)? One way I can think of is to create a clone of tank/home/foo called tank/home/bar, and then destroy the former. Is that the best (or even only) way? TIA, -- Rich Teer, SCSA, SCNA, SCSECA,

Hi all, What is the current preferred method for backing up ZFS data pools, preferably using free ($0.00) software, and assuming that access to individual files (a la ufsbackup/ufsrestore) is required?

So, does anyone know if I can run ZFS on my iPhone? ;-) -- richard

Hello, I believe that ZFS and it''s concepts is truly revolutionary to the point that I no longer see any OS as modern if it does not have comparable storage functionality. Therefore I think that file system/disk manager with similar qualities should be written for Linux. Does Sun have plans to dual license ZFS as GPL so it can be ported to native Linux? If not, is it legal to write

Hello. I''m a nobody. I use Linux. I have a hard-drive. I want the best / sexiest / what ever fs for my hard-drive, as it isn''t one of those flashy flash drives, which I presume don''t need an fs (???). I was THRILLED that the ZFS for Linux thread started. And, I was equally horrified (and sufficiently annoyed that I am starting this new thread) when it degraded in to

We''re planning to build a ZFS-based Solaris NFS fileserver environment with the backend storage being iSCSI-based, in part because of the possibilities for failover. In exploring things in our test environment, I have noticed that ''zpool import'' takes a fairly long time; about 35 to 45 seconds per pool. A pool import time this slow obviously has implications for how fast

Hi, I have Solaris Express snv_27 installed on an x86 pc with 4 SATA drives. I have 1 zpool called data with 16 ZFS filesystems. From times to times, it looks like ZFS falls asleep, i.e. when I do a df -k, it takes about a second to list each ZFS filesystem. If I re-issue the command straight away or a couple of minutes later, it takes a second to list all the filesystems. I checked in the

I assume that a zvol has a vtoc. What tags are supported? Thanks, Brian -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.opensolaris.org/pipermail/zfs-discuss/attachments/20070427/57e1a64f/attachment.html>

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. I''m happy to inform that the ZFS file system is now part of the FreeBSD operating system. ZFS is available in the HEAD branch and will be available in FreeBSD 7.0-RELEASE as an experimental feature. Commit log: Please welcome ZFS - The last word in file systems. ZFS file system was ported from OpenSolaris operating system. The code in under CDDL license. I''d

Hi. I''d like to request a feature be added to zfs. Currently, on SAN attached disk, zpool shows up with a big WWN for the disk. If ZFS (or the zpool command, in particular) had a text field for arbitrary information, it would be possible to add something that would indicate what LUN on what array the disk in question might be. This would make troubleshooting and general

Hi, I just installed 2009.06 and found that compression isn''t enabled by default when filesystems are created. Does is make sense to have an RFE open for this? (I''ll open one tonight if need be.) We keep telling people to turn on compression. Are there any situations where turning on compression doesn''t make sense, like rpool/swap? what about rpool/dump? Thanks, ~~sa

ZFS fans, I''m preparing some analyses on RAS for large JBOD systems such as the Sun Fire X4500 (aka Thumper). Since there are zillions of possible permutations, I need to limit the analyses to some common or desirable scenarios. Naturally, I''d like your opinions. I''ve already got a few scenarios in analysis, and I don''t want to spoil the brain storming, so

Hi. If I create a zpool with the following command: zpool create tank raidz2 da0 da1 da2 da3 da4 da5 da6 da7 and after a reboot the device names for some reason are changed so da2 and da5 are swapped, either by altering the LUN setting on the storage or by switching cables/swapping disks etc.? How will zfs handle that? Will it simply acknowledge that all devices are present and the pool is

Hey Guys, Have any of y''all seen a condition where the ILOM considers a disk faulted (status is 3 instead of 1), but ZFS keeps writing to the disk and doesn''t report any errors? I''m going to do a scrub tomorrow and see what comes back. I''m curious what caused the ILOM to fault the disk. Any advice is greatly appreciated. Best Regards, Jason P.S. The system is

With the release of the Nevada build 90 binaries, it is now possible to install SXCE directly onto a ZFS root filesystem, and also put ZFS swap onto a ZFS filesystem without worrying about having it deadlock. ZFS now also supports crash dumps! To install SXCE to a ZFS root, simply use the text-based installer, after choosing "Solaris Express" from the boot menu on the DVD. DVD download

Hi all, Space is starting to get a bit tight here, so I''m looking at adding a couple of TB to my home server. I''m considering external USB or FireWire attached drive enclosures. Cost is a real issue, but I also want the data to be managed by ZFS--so enclosures without a JBOD option have been disgarded (i.e., I don''t want to use any internal HW RAID controllers). One
