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

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 know i''m probably doing something REALLY stupid.....but for some reason i can''t get send/recv to work over ssh. I just built a new media server and i''d like to move a few filesystem from my old server to my new server but for some reason i keep getting strange errors... At first i''d see something like this: pfexec: can''t get real path of

I noticed an oddity on my 2008.05 box today. Created a new zfs file system that I was planning to nfs share out to an old FreeBSD box, after I put sharenfs=on for it, I noticed there was a bunch of others shared too: -bash-3.2# dfshares -F nfs RESOURCE SERVER ACCESS TRANSPORT reaver:/store/movies reaver - - reaver:/export

OK I have a very large zfs snapshot I want to destroy. When I do this, the system nearly freezes during the zfs destroy. This is a Sun Fire X4600 with 128GB of memory. Now this may be more of a function of the IO device, but let''s say I don''t care that this zfs destroy finishes quickly. I actually don''t care, as long as it finishes before I run out of disk space. So a

Hi, I have two servers running: freebsd with a zpool v28 and a nexenta (opensolaris b134) running zpool v26. Replication (with zfs send/receive) from the nexenta box to the freebsd works fine, but I have a problem accessing my replicated volume. When I''m typing and autocomplete with tab key the command cd /remotepool/us (for /remotepool/users) I get a panic. check the panic @

Greetings, Quick question: I am about to acquire some disks for use with ZFS (currently using zfs-fuse v0.7.0). I''m aware of some 4k alignment issues with Western Digital advanced format disks. As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses 512B sectors and so I presume does not suffer from such issues (because it doesn''t lie about the physical layout

Hello, I''m debating an OS change and also thinking about my options for data migration to my next server, whether it is on new or the same hardware. Migrating to a new machine I understand is a simple matter of ZFS send/receive, but reformatting the existing drives to host my existing data is an area I''d like to learn a little more about. In the past I''ve asked about

root at nas:~# zpool export -f raid cannot export ''raid'': pool is busy I''ve disabled all the services I could think of. I don''t see anything accessing it. I also don''t see any of the filesystems mounted with mount or "zfs mount". What''s the deal? This is not the rpool, so I''m not booted off it or anything like that.

I have a fresh install of Solaris 11 Express on a new SSD. I have inserted the old hard disk, and tried to import it, with: # zpool import -f <long id number> Old_rpool but the computer reboots. Why is that? On my old hard disk, I have 10-20 BE, starting with OpenSolaris 2009.06 and upgraded to b134 up to snv_151a. I also have a WinXP entry in GRUB. This hard disk is partitioned, with a

I figured the following ZFS ''success story'' may interest some readers here. I was interested to see how much sequential read/write performance it would be possible to obtain from ZFS running on commodity hardware with modern features such as PCI-E busses, SATA disks, well-designed SATA controllers (AHCI, SiI3132/SiI3124). So I made this experiment of building a fileserver by

What ''verbose information'' is reported by the "zfs send -v <snapshot>" contain? Also on Solaris 10u6 I don''t get any output at all - is this a bug? Regards, Nick -- This message posted from opensolaris.org

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

My google-fu is coming up short on this one... I didn''t see that it had been discussed in a while ... What is the status of ZFS support for TRIM? For the pool in general... and... Specifically for the slog and/or cache??? -------------- next part -------------- An HTML attachment was scrubbed... URL:

zdb -C shows an shift value on each vdev in my pool, I was just wondering if it is vdev specific, or pool wide. Google didn''t seem to know. I''m considering a mixed pool with some "advanced format" (4KB sector) drives, and some normal 512B sector drives, and was wondering if the ashift can be set per vdev, or only per pool. Theoretically, this would save me some size on
