Hi All, I believe this has been asked before, but I wasn?t able to find too much information about the subject. Long story short, I was moving data around on a storage zpool of mine and a zfs destroy <filesystem> hung (or so I thought). This pool had dedup turned on at times while imported as well; it?s running on a Nexenta Core 3.0.1 box (snv_134f). The first time the machine was

Is there an easy way to find out what datasets have dedup''d data in them. Even better would be to discover which files in a particular dataset are dedup''d. I ran # zdb -DDDD which gave output like: index 1055c9f21af63 refcnt 2 single DVA[0]=<0:1e274ec3000:2ac00:STD:1> [L0 deduplicated block] sha256 uncompressed LE contiguous unique unencrypted 1-copy size=20000L/20000P

I need to move data from one zpool to another, lock stock and barrel, Being from linux background my instinct was to use rsync. But then I remembered seeing the `export/import options in man zpool.. And I''ve seen mention of them here too, but didn''t pay attention since I''d noticed no need yet. Now I''m wondering if the export/import sub commands might not be

I was wondering what the best method of moving a pool from FreeBSD 8.0 to OpenSolaris is. When i originally built my system, it was using hardware which wouldn''t work in opensolairs, but i''m about to do an upgrade so i should be able to use Opensolaris when i''m done. My current system uses a Highpoint RocketRaid 2340. It has 12 1TB hard drives an intel core2 quad

Like many others, I am looking to put together a SOHO NAS based on ZFS/CIFS. The plan is 6 x 1TB drives in RAIDZ2 configuration, driven via mobo with 6 SATA ports. I''ve read most, if not all, of the threads here, as well as sbredon''s excellent article on building a home NAS, yet I still have a number of unanswered questions. I was leaning heavily towards the M2N-E for a while,

We recently installed a 24 disk SATA array with an LSI controller attached to a box running Solaris X86 10 Release 4. The drives were set up in one big pool with raidz, and it worked great for about a month. On the 4th, we had the system kernel panic and crash, and it''s now behaving very badly. Here''s what diagnostic data I''ve been able to collect so far: In the

Hi guys, I have a quick question, I am playing around with ZFS and here''s what I did. I created a storage pool with several drives. I unplugged 3 out of 5 drives from the array, currently: NAME STATE READ WRITE CKSUM gpool UNAVAIL 0 0 0 insufficient replicas raidz1 UNAVAIL 0 0 0 insufficient replicas c8t2d0 UNAVAIL 0 0

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

This Asus board looks promising, assuming the parts (nForce 680a chipset) are Solaris friendly: http://www.asus.com.tw/products4.aspx?l1=3&l2=136&l3=486&model=1530&modelmenu=2 The board boasts 12 (!) SATA2 ports. The FX-7x series CPUs appear to be a very cost effective ($799) 4 core solution. Ian

One quick question: When will the next formal release be released? Does oracle have plan to support OpenSolaris community as Sun did before? What is the direction of ZFS in future? -- This message posted from opensolaris.org

Hi all, from much of the documentation I''ve seen, the advice is to set readonly=on on volumes on the receiving side during send/receive operations. Is this still a requirement? I''ve been trying the send/receive while NOT setting the receiver to readonly and haven''t seen any problems even though we''re traversing and ls''ing the dirs within the receiving

Good morning. I am in the process of planning a system which will have 2 ZFS servers, one on site, one off site. The on site server will be used by workstations and servers in house, and most of that will stay in house. There will, however, be data i want backed up somewhere else, which is where the offsite server comes in... This server will be sitting in a Data Center and will have some storage

Oracle have deleted the best ZFS platform I know, the X4540. Does anyone know of an equivalent system? None of the current Oracle/Sun offerings come close. -- Ian.

Setup: Osol.11 build 109 Athlon64 3400+ Aopen AK-86L mobo adeptec 1250sa Sata PCI controller card [re-posted from accidental post to osol `general'' group] I''m having trouble with an adaptec 1205sa (non-raid) SATA PCI card. It was all working fine when I plugged 2 used sata 200gb disks of a windows xp machine into it. Booted my osol server and added a zpool mirror using those

Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

Hi, everyone! I have a beginner''s question: I must configure a small file server. It only has two disk drives, and they are (forcibly) destined to be used in a mirrored, hot-spare configuration. The OS is installed and working, and rpool is mirrored on the two disks. The question is: I want to create some ZFS file systems for sharing them via CIFS. But given my limited configuration:
