Dear ZFS-Users, I want to switch to ZFS, but still want to encrypt my data. Native Encryption for ZFS was added in "ZFS Pool Version Number 30<http://en.wikipedia.org/wiki/ZFS#Release_history>", but I''m using ZFS on FreeBSD with Version 28. My question is how would encfs (fuse encryption) affect zfs specific features like data Integrity and deduplication? Regards

OK, general question for the community -- what''s the coolest startup using Rails? I don''t think "37 Signals" is a fair answer. I''m curious as to what kind of other developments are happening. Are there a lot of startups using Rails in the first place? Or do most of you who are lucky enough to do Rails for a living (I''m coding Java, bleah) work in large

Howdy All, I''ve a bit of a strange problem here. I have a filesystem with one snapshot that simply refuses to be destroyed. The snapshots just prior to it and just after it were destroyed without problem. While running the zfs destroy command on this particular snapshot, the server becomes more-or-less hung. It''s pingable but will not open a new shell (local or via ssh) however

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

Hi, We are considering using a ZFS based storage as a staging disk for Networker. We''re aiming at providing enough storage to be able to keep 3 months worth of backups on disk, before it''s moved to tape. To provide storage for 3 months of backups, we want to utilize the dedup functionality in ZFS. I''ve searched around for these topics and found no success stories,

Hi, I am facing issue with zfs destroy, this takes almost 3 Hours to delete the snapshot of size 150G. Could you please help me to resolve this issue, why zfs destroy takes this much time. While taking snapshot, it''s done within few seconds. I have tried with removing with old snapshot but still problem is same. =========================== I am using : Release : OpenSolaris

Hi, Created a zpool with 64k recordsize and enabled dedupe on it. zpool create -O recordsize=64k TestPool device1 zfs set dedup=on TestPool I copied files onto this pool over nfs from a windows client.

There's an old Ubisoft game called "Hype the Time Quest". For many Wine versions, Wine could not get past the Hype installer. It would go up to 117% and fail. Then a version came where if you unchecked the DirectX check, the install would work (or maybe that's all you had to do to begin with). But the game would fail to start with an error about MaiD3Dvr_bleu.exe. Then a Wine

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the

Hello, I was bored this weekend so I hacked up online dedup for Btrfs. It''s working quite well so I think it can be more widely tested. There are two ways to use it 1) Compatible mode - this is a bit slower but will handle being used by older kernels. We use the csum tree to find duplicate blocks. Since it is relatively easy to have crc32c collisions this also involves reading the

Asked a little while back about "coolest startups" using Rails, I think it''d have been better had I asked "coolest software." Besides the obvious (37Signals, Typo, Yakima Herald, Odeo, Measure Map, etc.), I''m just curious about other developments where people are using it to make nifty stuff. -- Giles Bowkett www.gilesgoatboy.org

Hi, I was suffering for weeks from the following problem: a zfs dataset contained an automatic snapshot (monthly) that used 2.8 TB of data. The dataset was deprecated, so I chose to destroy it after I had deleted some files; eventually it was completely blank besides the snapshot that still locked 2.8 TB on the pool. ''zfs destroy -r pool/dataset'' hung the machine within seconds

Hello, some questions regarding btrfs deduplication. - What is the state of it? Is it "safe" to use? https://btrfs.wiki.kernel.org/index.php/Deduplication does not yield much information. - https://pypi.python.org/pypi/bedup says: "bedup looks for new and changed files, making sure that multiple copies of identical files share space on disk. It integrates deeply with btrfs so

In reading this blog post: http://blogs.sun.com/bobn/entry/taking_zfs_deduplication_for_a a question came to mind..... To understand the context of the question, consider the opening paragraph from the above post; Here is my test case: I have 2 directories of photos, totaling about 90MB > each. And here''s the trick - they are almost complete duplicates of each > other. I downloaded

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

Dear All : Under Sun Storage 7000 system, can we see per share ratio after enable dedup function ? We would like deep to see each share dedup ratio. On Web GUI, only show dedup ratio entire storage pool. Thanks a lot, -- Rex -- This message posted from opensolaris.org

Hi all Has anyone done any testing with dedup with OI? On opensolaris there is a nifty "feature" that allows the system to hang for hours or days if attempting to delete a dataset on a deduped pool. This is said to be fixed, but I haven''t seen that myself, so I''m just wondering... I''ll get a 10TB test box released for testing OI in a few weeks, but before

I tried the deduplication feature but the performance of my fileserver dived from writing 50MB/s via CIFS to 4MB/s. what happens to the deduped blocks when you set dedup=off? are they written back to disk? is the deduptable deleted or is it still there? thanks -- This message posted from opensolaris.org
