similar to: zfs destroy snapshot: dataset already exists?

Can I send a zfs send stream (ZFS pool version 22 ; ZFS filesystem version 4) to a zfs receive stream on Solaris 10 (ZFS pool version 15 ; ZFS filesystem version 4)? -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + http://nagual.nl/ | SunOS 10u7 5/09 | OpenSolaris 2010.03 b131 + All that''s really worth doing is what we do for others (Lewis Carrol)

Hi all, I installed another OpenSolaris (snv_129) in VirtualBox 3.1.0 on Windows because snv_130 doesn''t boot anymore after installation of VirtualBox guest additions. Older builds before snv_129 were running fine too. I like some features of this OS, but now I end with something funny. I installed default snv_129, installed guest additions -> reboot, set

We have a pair of opensolaris systems running snv_124. Our main zpool ''z'' is running ZFS pool version 18. Problem: #zfs destroy -f z/Users/harrison at zfs-auto-snap:daily-2010-04-09-00:00 cannot destroy ''z/Users/harrison at zfs-auto-snap:daily-2010-04-09-00:00'': dataset is busy I have tried: Unable to destroy numerous datasets even with a -f option.

Hello, I have a ZFS filesystem (zpool version 26 on Nexenta CP 3.01) which I''d like to rollback but it''s having an existential crisis. Here''s what I see: root at bambi:/# zfs rollback bambi/faline/userdocs at AutoD-2010-09-28 cannot rollback to ''bambi/faline/userdocs at AutoD-2010-09-28'': more recent snapshots exist use ''-r'' to

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

Nothing too interesting here, I was just playing around with the idea of a deduplication allocator for nbdkit (“allocator=dedup”, see https://rwmj.wordpress.com/2020/06/15/compressed-ram-disks/). Before implementing such a thing I wanted to know if there's much duplicated structure in a disk image. It seems to depend very critically on the block size, but also there are no significant

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

This article raises the concern that SSD controllers (in particular SandForce) do internal dedup, and in particular that this could defeat ditto-block style replication of critical metadata as done by filesystems including ZFS. http://storagemojo.com/2011/06/27/de-dup-too-much-of-good-thing/ Along with discussion of risk evaluation, it also suggests that filesystems could vary each copy in some

Greetings Gentlemen, I''m currently testing a new setup for a ZFS based storage system with dedup enabled. The system is setup on OI 148, which seems quite stable w/ dedup enabled (compared to the OpenSolaris snv_136 build I used before). One issue I ran into, however, is quite baffling: With iozone set to 32 threads, ZFS''s ARC seems to consume all available memory, making

Hello; Dedup on ZFS is an absolutely wonderful feature! Is there a way to conduct dedup replication across boxes from one dedup ZFS data set to another? Warmest Regards Steven Sim

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

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'm new to spatial analysis and am exploring numerous packages, mostly enjoying sp, gstat, and spBayes. Is there a function that allows the user to dedup a data set with multiple values at the same coordinates and replace those duplicated values with the mean at those coordinates? I've written some cumbersome code that works, but would prefer an efficient R function if it exists.

I''m playing around with snv_128 on one of my systems, and trying to see what kinda of benefits enabling dedup will give me. The standard practice for reprocessing data that''s already stored to add compression and now dedup seems to be a send / receive pipe similar to: zfs send -R <old fs>@snap | zfs recv -d <new fs> However, according to the man page,

Hi! When I run test:units, rails complains about the tables already being present. They had to be present so I could run individual unit tests. So why doesn''t rails just drop the tables if they exist? Any ideas?? Jeroen debug oupt below: >rake test:units --trace (in ...) ** Invoke test:units (first_time) ** Invoke db:test:prepare (first_time) ** Invoke environment (first_time)

I''m working on a system that has a series od "bids" associated with "posts". Vurrently when a bid is placed I have it creating a new row each time in the "bids" table. The bids table has id, post_id, and user_id. The logic is to check to see if a bid already exists with a given post_id and user_id. If it does, then just update the "amount"
