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

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

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

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

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,

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

Hi, I was playing around with NexentaCP and its zfs boot facility. I tried to figure out how what commands to run and I ran zpool history like this # zpool history 2007-06-20.10:19:46 zfs snapshot syspool/rootfs at mysnapshot 2007-06-20.10:20:03 zfs clone syspool/rootfs at mysnapshot syspool/myrootfs 2007-06-20.10:23:21 zfs set bootfs=syspool/myrootfs syspool As you can see it says I did a

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

Hi guys, I'm running a NT Domain hosted on two Debian GNU/Linux Sarge servers running Samba (respectively as PDC and as member server), with lots of horsepower (dual-cpu with 1GB RAM or more each). Samba itself is behaving blazingly fast, from both servers. I use winbind on the member server, of course. Still, on this machine I see each week a huge performance drop related authentication, to

I created a zfs pool with dedup with the following settings: zpool create data c8t1d0 zfs create data/shared zfs set dedup=on data/shared The thing I was wondering about was it seems like ZFS only dedup at the file level and not the block. When I make multiple copies of a file to the store I see an increase in the deup ratio, but when I copy similar files the ratio stays at 1.00x. -- This

I''m looking at the newly-orderable (via Sun) STEC Zeus SSDs, and they''re outrageously priced. http://www.stec-inc.com/product/zeusssd.php I just looked at the Intel X25-E series, and they look comparable in performance. At about 20% of the cost. http://www.intel.com/design/flash/nand/extreme/index.htm Can anyone enlighten me as to any possible difference between an STEC

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

Hi all, I currently have four drives in my OpenSolaris box. The drives are split into two mirrors, one mirror containing my rpool (disks 1 & 2) and one containing other data (disks 2 & 3). I''m running out of space on my data mirror and am thinking of upgrading it to two 2TB disks. I then considered replacing disk 2 with a 2TB disk and making a RAIDz from the three new drives.

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

Hello Everyone, My question is simply what are my best options for successfully installing virtual tools on an Open Solaris OS running on Sparc Architecture. My hardware is a Sun Blade 2500. From what I have read Virtualbox and Xen do not work on Sparc technologies. What options do I have? Thank you in advance for any advice, Dan -- This message posted from opensolaris.org

Hi, quoting from zfs docs "The SPA allocates blocks in a round-robin fashion from the top-level vdevs. A storage pool with multiple top-level vdevs allows the SPA to use dynamic striping to increase disk bandwidth. Since a new block may be allocated from any of the top-level vdevs, the SPA implements dynamic striping by spreading out writes across all available top-level vdevs" Now,

-----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 -
