To improve the performance of scripts that manipulate zfs snapshots and the zfs snapshot service in perticular there needs to be a way to list all the snapshots for a given object and only the snapshots for that object. There are two RFEs filed that cover this: http://bugs.opensolaris.org/view_bug.do?bug_id=6352014 : ''zfs list'' should have an option to only present direct

Hi, this says that opensolaris only requires 512MB ram: http://dlc.sun.com/osol/docs/content/IPS/sysreq.html This says 1GB ram and a 64bit processor are recommended: http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#Memory_and_Swap_Space Am I going to have problems if I run opensolaris and zfs at the minimum requirements? -- This message posted from opensolaris.org

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,

Hello All I read this thread Resilver/scrub times? for a few minutes and I have recognize that I dont know the different between Resilvering and Scrubing. Shame on me. :-( I dont find some declarations in the man-pages and I know the command to start scrubing "zpool scrub tank" but what is the command to start resilver and what is the different? -- Best Regards Alexander Dezember, 20

Hello all. We''re a pretty traditional old school sun shop w/a few dozen sun boxes from 1999-2004. We''re doing a try and buy on a sun blade 6000 with a couple of 6250 intel blades and a 6320 blade, looking to use multiple chassis to do a consolidation, using ldoms and xvm server with xvm ops center to manage it all. At least that''s our forward looking plan.... to move

Hi, as Richard Elling wrote earlier: "For more background, low-cost SSDs intended for the boot market are perfect candidates. Take a X-25V @ 40GB and use 15-20 GB for root and the rest for an L2ARC. For small form factor machines or machines with max capacity of 8GB of RAM (a typical home system) this can make a pleasant improvement over a HDD-only implementation." For the upcoming

Hello, Experts. I''ve got a problem. I''m trying to expand my main zpool (rpool), but don''t know how to do that. (i''m 100% newbie in non-windows world) I use Osol under Vmware on Windows. I had a pretty small vhdd -> only 12gb. Yesterday i decided to expand my virtual drive to 20gb. (After several tries to upgrade the OS to a newest dev-releases and

I am running OpenSolaris build 134 on a T1000 (Sparc). It has been an uphill battle getting this far. Many of the commands I find in the various documentation won''t work for me. ------------------------------------------------------------ steve@t1000:~# pfexec pkg install xvm-gui Creating Plan pkg: ''xvm-gui'' matches multiple packages

I''d like to replace/upgrade two 500GB disks in RaidZ2 vdev with 1TB disks, but I have some preliminary questions/concerns before trying ''zfs replace dpool ?'' Will ZFS permit this replacement? Will ZFS use the extra space in a heterogeneous RaidZ2 vdev, or is the size limited by the smallest disk in the vdev? Thanks in advance, Vizzini The system is currently running

We have Sun STK RAID cards in our x4170 servers. These are battery backed with 256mb cache. What is the recommended ZFS configuration for these cards? Right now, I have created a one-to-one logical volume to disk mapping on the RAID card (one disk == one volume on RAID card). Then, I mirror them using ZFS. No hardware mirror. What I am a little confused with is if it is better to not do any

We are looking at adding to our storage. We would like ~20TB-30 TB. we have ~ 200 nodes (1100 cores) to feed data to using nfs, and we are looking for high reliability, good performance (up to at least 350 MBytes /second over 10 GigE connection) and large capacity. For the X45xx (aka thumper) capacity and performanance seem to be there (we have 3 now) However, for system upgrades , maintenance

Dear all, given a DVD drive and DAT Tape Drive, and using Solaris 10 U7 (5/09), how can we plan for a total backup of ZFS root disk and procedure to recover that? Previously using UFS, we just need to use boot from Solaris OS DVD media, also using ufsdump, ufsrestore and installboot. Anybody can point me on how to achieve the same thing when the whole system disk are busted? Thanks in

Do we have enormous fragmentation here on our X4500 with Solaris 10, ZFS Version 10? What except zfs send/receive can be done to free the fragmented space? One ZFS was used for some month to store some large disk images (each 50GByte large) which are copied there with rsync. This ZFS then reports 6.39TByte usage with zfs list and only 2TByte usage with du. The other ZFS was used for similar

I have an Intel X25-M 80GB SSD. For optimum performance, I need to block align the SSD device, but I am not sure exactly how I should to it. If I run the format -> fdisk it allows me to partition based on a cylinder, but I don''t think that is sufficient enough. Can someone tell me how they block aligned an SSD device for use in l2arc. Thanks, Geoff

Since the j4500 doesn''t have a internal SAS controller, would it be safe to say that ZFS cache flushes would be handled by the host''s SAS hba? -- This message posted from opensolaris.org

I figure this group will know better than any other I have contact with, is 700-800 I/Ops reasonable for a 7200 RPM SATA drive (1 TB Sun badged Seagate ST31000N in a J4400) ? I have a resilver running and am seeing about 700-800 writes/sec. on the hot spare as it resilvers. There is no other I/O activity on this box, as this is a remote replication target for production data. I have a the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 zpool and zfs report different free space because zfs takes into account an internal reservation of 32MB or 1/64 of the capacity of the pool, what is bigger. So in a 2TB Harddisk, the reservation would be 32 gigabytes. Seems a bit excessive to me... - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea at jcea.es -

Hi, I''m looking to build a virtualized web hosting server environment accessing files on a hybrid storage SAN. I was looking at using the Sun X-Fire x4540 with the following configuration: - 6 RAID-Z vdevs with one hot spare each (all 500GB 7200RPM SATA drives) - 2 Intel X-25 32GB SSD''s as a mirrored ZIL - 4 Intel X-25 64GB SSD''s as the L2ARC. -

While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more
