similar to: How can I copy a ZFS filesystem back and forth

Hi, I have just observed the following issue and I would like to ask if it is already known: I''m using zones on ZFS filesystems which were cloned from a common template (which is itself an original filesystem). A couple of weeks ago, I did a pkg image-update, so all zone roots got cloned again and the new zone roots got promoted. I then decided to undo the update and promoted the

Hi, I want to move all the ZFS fs from one pool to another, but I don''t want to "gain" an extra level in the folder structure on the target pool. On the source zpool I used zfs snapshot -r tank at moveTank on the root fs and I got a new snapshot in all sub fs, as expected. Now, I want to use zfs send -R tank at moveTank | zfs recv targetTank/... which would place all zfs fs

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

Hi, I want to send peices of a zfs filesystem to another system. Can zfs send peices of a snapshot? Say I only want to send over /app at today and not include /app/conf data while /app/conf is still apart of the /app at today snapshot? I say app/conf as an example, it could be webserver/http-webservername/config or a piece of a repository. I know once the receive -F option is added

I managed to create a link in a ZFS directory that I can''t remove. Session as follows: # ls bayes.lock.router.3981 bayes_journal user_prefs # ls -li bayes.lock.router.3981 bayes.lock.router.3981: No such file or directory # ls bayes.lock.router.3981 bayes_journal user_prefs # /usr/sbin/unlink bayes.lock.router.3981 unlink: No such file or directory # find . -print

Hello, Is there a way to upgrade my current ZFS version. I show the version could be as high as 22. I tried the command below. It seems that you can only upgrade by upgrade the OS release. [ilmcoso0vs056:root] / # zpool upgrade -V 16 tank invalid version ''16'' usage: upgrade upgrade -v upgrade [-V version] <-a | pool ...> [ilmcoso0vs056:root] /

Is there a mechanism by which you can perform a zfs send | zfs receive and not have the data uncompressed and recompressed at the other end? I have a gzip-9 compressed filesystem that I want to backup to a remote system and would prefer not to have to recompress everything again at such great computation expense. If this doesn''t exist, how would one go about creating an RFE for

I have the following configuation. My storage: 12 luns from a Clariion 3x80. Each LUN is a whole 6 disk raid-6. My host: Sun t5240 with 32 hardware threads and 16gig of ram. My zpool: all 12 luns from the clariion in a simple pool My test data: A 1 gig backup file of a ufsdump from /opt on a machine with lots of mixed binary/text data. A 15gig file that is already tightly compressed. I wrote

I had some trouble installing a zone on ZFS with S10u4 (bug in the postgres packages) that went away when I used a ZVOL-backed UFS filesystem for the zonepath. I thought I''d push on with the experiment (in the hope Live Upgrade would be able to upgrade such a zone). It''s a bit unwieldy, but everything worked reasonably well - performance isn''t much worse than straight

Hi. Using ZFS-FUSE. $SUBJECT happened 3 out of 5 times while testing, just wanna know if someone has seen such scenario before. Steps: ------------------------------------------------------------ root at localhost:/# uname -a Linux localhost 2.6.24-24-generic #1 SMP Wed Apr 15 15:54:25 UTC 2009 i686 GNU/Linux root at localhost:/# zpool upgrade -v This system is currently running ZFS pool

Hi, I just installed 2009.06 and found that compression isn''t enabled by default when filesystems are created. Does is make sense to have an RFE open for this? (I''ll open one tonight if need be.) We keep telling people to turn on compression. Are there any situations where turning on compression doesn''t make sense, like rpool/swap? what about rpool/dump? Thanks, ~~sa

Hello everyone, I am trying to take ZFS snapshots (ie. zfs send) and burn them to DVD''s for offsite storage. In many cases, the snapshots greatly exceed the 8GB I can stuff onto a single DVD-DL. In order to make this work, I have used the "split" utility to break the images into smaller, fixed-size chunks that will fit onto a DVD. For example: #split -b8100m

Hi, We are using multiple opensolaris 06/09 and solaris 10 servers. Currently we are ''dumping'' (incremental)backups to a backup server. I wonder if anybody knows what happens when I send/recv a zfs volume from version 15 to a (backup) system with version 14. I''ve the feeling it''s not very wise to do, but is it doable and what kind of caveats can be

Looking for a little help, please. A contact from Oracle (Sun) suggested I pose the question to this email. We''re using ZFS on Solaris 10 in an application where there are so many directory-subdirectory layers, and a lot of small files (~1-2Kb) that we ran out of inodes (over 30 million!). So, the zfs question is, how can we see how many files & directories have been created in

I have some questions about modify filesystem block. When we want to modify existing block ZFS makes new one and destroy old. OK - it is copy-on-write mechanism. But if we want to modify only a part of the block what does it work? What does ZFS do with rest of the block? Whether size of it is reduce or maybe write to new place?

Folks, While going through a quick tutorial on zfs, I came across a way to create zfs filesystem within a filesystem. For example: # zfs create mytest/peter where mytest is a zpool filesystem. When does this way, the new filesystem has the mount point as /mytest/peter. When does it make sense to create such a filesystem versus just creating a directory? # mkdir mytest/peter Thank you in

I have to backup many filesystems, which are changing and machines are heavy loaded. The idea is to backup online - this should avoid I/O read operations from disks, data should go from cache. Now I''m using script that does snapshot and zfs send. I want to automate this operation and add new option to zfs send zfs send [-w sec ] [-i <snapshot>] <snapshot> for example

This may be a dumb question, but is there a way to find out if an arbitrary filesystem is actually a zfs filesystem? Like if I were to write a script that needs to do different steps based on the underlying filesystem. Any pointers welcome. -- Jan Hendrik Mangold Sun Microsystems 650-585-5484 (x81371) "idle hands are the developers workshop" -------------- next part

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,
