We finally flipped the switch on one of our ZFS-based servers, with approximately 1TB of 2.8TB (3 stripes of 950MB or so, each of which is a RAID5 volume on the adaptec card). We have snapshots every 4 hours for the first few days. If you add up the snapshot references it appears somewhat high versus daily use (mostly mail boxes, spam, etc chang...

how does one free segment(offset=77984887808 size=66560) on a pool that won''t import? looks like I found http://bugs.opensolaris.org/view_bug.do?bug_id=6580715 http://mail.opensolaris.org/pipermail/zfs-discuss/2007-September/042541.html when I luupgrade a ufs partition with a dvd-b62 that was bfu to b68 with a dvd of b74 it booted fine and I was doing the same thing that I had done on another machine (/usr can live on raidz if boot is ufs) on a zfs destroy -r z/snv_68 with lzjb and {usr var op...

With the release of the Nevada build 90 binaries, it is now possible to install SXCE directly onto a ZFS root filesystem, and also put ZFS swap onto a ZFS filesystem without worrying about having it deadlock. ZFS now also supports crash dumps! To install SXCE to a ZFS root, simply use the text-based installer, after choosing "Solaris Express" from the boot menu on the DVD. DVD download lin...

Hello folks, I have a question and a small problem... I did try to replicate my zfs with all the snaps, so I did run few commands: time zfs send mypool/d at 2006_month_10 | zfs receive mypool2/d at 2006_month_10 real 6h35m12.34s user 0m0.00s sys 29m32.28s zfs send -i mypool/d at 2006_month_10 mypool/d at 2006_month_12 | zfs receive mypool/d at 2006_month_12 real 4h...

Looking for help regaining access to encrypted ZFS file systems that stopped accepting the encryption key. I have a file server with a setup as follows: Solaris 11 Express 1010.11/snv_151a 8 x 2-TB disks, each one divided into three equal size partitions, three raidz3 pools built from a "slice" across matching partitions: Disk 1 Di...

I have a raid-z zfs filesystem with 3 disks. The disk was starting have read and write errors. The disks was so bad that I started to have trans_err. The server lock up and the server was reset. Then now when trying to import the pool the system panic. I installed the last Recommend on my Solaris U3 and also install...

Hi All, I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see...

Hi and hello, I have a problem confusing me. I hope someone can help me with it. I followed a "best practise" - I think - using dedicated zfs filesystems for my virtual machines. Commands (for completion): [i]zfs create rpool/vms[/i] [i]zfs create rpool/vms/vm1[/i] [i] zfs create -V 10G rpool/vms/vm1/vm1-dsk[/i] This command creates the file system [i]/rpool/vms/vm1/vm1-dsk[/i] and the according [i]/dev/zvol/dsk/rpool/vms/vm1/vm1-dsk[/i...

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 tan...
