[OpenIndiana-discuss] Antwort: Transferring everything in one zpool to be a subtree in another larger zpool
Hi, I have this old machine running oi151a7 with a zpool containing a set of filesystems used for media files of various types, and I want to transfer them all, in one go, safely but not unnecessarily slowly, to a new zpool on a different machine. The old zpool is on a 2tb two-disk mirror on the oi151a7, while the new zpool is a freenas raidz2 of 12tb or so actual data space. I want your advice on what is the correct, safest and/or most practical way to do it. Both machines are on a GB network, and neither of them will be doing anything else while transferring the data. I'm guessing zfs send/recv over the network, using nc for buffering, but I've never done this before, so please advice me. Quite easy with zfs and a little time for the sending/receiving process: 1) Create a snapshot of the pool you intend to move: root@oldmachine:# zfs snapshot -r oldpool@snapshot_name 2) Send the pool to your new machine: root@oldmachine:# zfs send -R oldpool@snapshot_name | \ ssh root@new_machine '/usr/sbin/zfs receive newpool/new_name' -R creates a replication stream package that sends everything recursively up to the named snapshot, including properties, snapshots, descendent file systems and clones. If you're not interested in older snapshots, use -rp instead of -R whereas -r creates a recursive stream package and -p tells zfs send to include properties. 3) Have a coffee or two and wait :-) 4) Optionally move the received zfs filesystems, volumes, ... one level up in your new pool: root@newmachine:# zfs rename newpool/new_name/filesystem1 newpool/filesystem1 I have done this several times in the past without problems. You could optionally compress the stream with gzip and uncompress it when receiving: root@oldmachine:# zfs send -R oldpool@snapshot_name | gzip | \ ssh root@new_machine '/usr/bin/gunzip | /usr/sbin/zfs receive newpool/new_name' In my experience with some 100GB of data this took far longer in our LAN than the same without compressing although the sending and receiving machines should have been fast enough... If you don't want to send the whole pool, replace oldpool above with the file system / data set you're interested in; the commands stay the same.

[OpenIndiana-discuss] OI updates
I've just pushed a collection of illumos-gate CVE fixes for a9. This covers: - 5378 CVE-2014-3158 ppp: integer overflow in option parsing - 5480 CVE-2012-3165 mailx(1) buffer overflow vulnerability - 5481 CVE-2012-1750 mailx(1) tilde expansion vulnerability - 5853 pfexec_call() error handling could be improved 5854 pfexecd should initialize pfexec response buffers (Not sure what CVE this actually was assigned.) I've also pushed the NVIDIA driver update to 304.125 and the missing pieces of the Delphix vmxnet3s driver patchset. The new packages are: SUNWcs@0.5.11,5.11-0.151.1.9:20150504T114725Z system/network/ppp@0.5.11,5.11-0.151.1.9:20150504T120317Z consolidation/nvidia/nvidia-incorporation@0.5.11,5.11-0.151.1.9:20150504T113748Z driver/graphics/nvidia@0.304.125,5.11-0.151.1.9:20150504T113958Z driver/network/vmxnet3s@0.5.11,5.11-0.151.1.9:20150504T114139Z For those interested in an up to date OI branded illumos-gate, I've finished getting the OI patches done so anyone wishing to work with that can grab it here: https://github.com/OpenIndiana/illumos-gate That should build fine with GCC on hipster. If you build it with Studio on a9 you'll get a warning about clog (https://www.illumos.org/issues/5353) and warnings about pointers that can be fixed with https://paste.ec/paste/sDXMLQXR#DnPbnxkm9tFNmX0WxH1rWdV6CjIpGRmcKwfP2HOCgFE I've deliberately left out any broadcom patches that we had as there seems to be a mishmash of patches around from various sources and it's better for everyone if people look and work against upstream illumos-gate.

Re: [OpenIndiana-discuss] Antwort: Transferring everything in one zpool to be a subtree in another larger zpool
Thanks, that was exactly it. To add a few bits of info: You first must get a pair of private/public keys ssh-keyget -t rsa for the OI user to run the zfs send. Then copy the public key from ~/.ssh/id_rsa.pub on OI to the user root (or other user with admin privs) on freenas. In the web mgmt gui on freenas, click Account-view-users-root and click edit at the bottom. Put the contents of your .pub key into the public key field of the edit form. To test run ssh root@freenas_address ls When it works, run pfexec zfs send -R Tank/dataset@snapshot | ssh root@freenas_address '/sbin/zfs recv Tank/Media/name' on OI zfs on freenas is in /sbin, I suppose you could use password login for root on freenas, but freenas is set up to use rsa key controlled login for replication. So this way probably has been tested a lot more.

Re: [OpenIndiana-discuss] Java 8 plugin for Firefox
Check IcedTea, it works smoothly on my Linux at work.. After compiling OpenJDK 8 32-bit I compiled icedtea-web-1.6 and yes it works (please see the attached screen-shot). I guess OpenJKD and IcedTea should replace JDK in OpenIndiana etc. A.S. -- Apostolos Syropoulos Xanthi, Greece ___ openindiana-discuss mailing list openindiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
