My zfs filesystem hangs when transferring large filesystems (>500GB) with a couple dozen snapshots between servers using zfs send/receive with netcat. The transfer hangs about halfway through and is unkillable, freezing all IO to the filesystem, requiring a hard reboot. I have attempted this three times and failed every time. On the destination server I use: nc -l -p 8023 | zfs receive -vd sas

Hi, There''s something really bizarre in ZFS snaphot specs : "Uses no separate backing store." . Hum...if I want to mutualize one physical volume somewhere in my SAN as THE snaphots backing-store...it becomes impossible to do ! Really bad. Is there any chance to have a "backing-store-file" option in a future release ? In the same idea, it would be great to

Hello Folks, I am wondering what could be the problem now. I have succeeded in having an ssh login without password request. Reaching the last stage of creating the rbackup.sh, that's where I got the problem. I made this file executable by running this command chmod +x rbackup.sh Now, when I run this command (./backup.sh) to execute it, I get errors .....complaining of the source on line 53.

Hi everyone! Is there any way to create snaphot for a single disk of a virtual machine. As I konw, "virsh snapshot-create-as domain_name snapshot_name --disk-only" traverses all block devices to create snapshot. However I don't want to create snapshot except for root partition. The version of qemu and libvirt I used is as follows: qemu-1.4.2 and libvrit-0.10.2

Peter, One other thing. The first two times it crashed I erased the file tree created by rsync so that the snaphot started from scratch again. Each of these two times it got to exactly the same file: usr/lib/locale/es_CO/LC_COLLATE when it crashed. That was when I stopped rebuidling and re-cabling my hardware, because I saw a determinate pattern in the crashes... (sheepish) should have said

Hello, I have a Centos 6.2 clsuter with a CLVM partition on which I have a GFS2 file system. The problem rises when I make a snapshot from my FC NetAPP FAS2020. After I make the snapshot (it is a rw snapshot) of my LUN, I am not able to mount it from any of my cluster nodes, because the Physical Volume is seen two times one time on the standard LVM partition and the other time on the snapshot

Thanks for you reply! Firstly, I'm very sorry I forgot introduce the scenarios in my experiments. Supposing a case, I have a virtual machine with two disks. One is mounted as a root partition and the other is data partition and the second disk is an iscsi lun, that is to say, not a local disk or image. Now the result wanted is that creating a snapshot for the root disk but not for the data

I believe what I am going to write is a bug report. When I finaly did # btrfs send -v /mnt/adama-docs/backups/20130101-192722 | btrfs receive /mnt/tmp/backups to migrate btrfs from one partition layout to another. After a while system keeps saying that "Too many open files in system" and denies access to almost every command line tool. When I had access to iostat I confirmed the

Hi all, I am trying to test DirectShow PushSource example from the SDK with Theora encoder and Ogg muxer (DirectShow filters of course) by using GraphEdit tool. My goal is capturing the screen as video by taking snaphot bitmaps continuosly (what PushSource eaxmple does) and giving them to the Theora encoder through the DS pipeline (next goal is transmitting this video **). My DirectShow graph is

Hi, I''ve got a little problem with the comboboxes. I want to provide a search where the user enters a word into the combobox and the program runs a mysqlsearch and returns the result in the comboboxlist. While the user enters a searchword or moves up or down within the list, it is necessary that the list opens itself without a manual click on the button. That''s

Hi list, I have a Windows server backing up to a Linux server that continuously gets 'IO error encountered -- skipping file deletion' in the receiver log file. Could someone enlighten me where and what this error is referring to. I have tried various options, like using --delete or --delete-during. Still the same problem. Is it on the sender or receiver side, or a timeout encountered

Dear All, CentOs 6 is great, but I would like to get back 2 things from 5.6 : how can I always see the text lines during startup? (so no graphical screen ) how can I *not *see all the users on the system when loging on? (so that users also have to remember their username) thanks for any advise.

Hello All, the update to Centos6.6 got interrupted on a laptop. I then did this: package-cleanup --cleandupes yum-complete-transaction and remove and reinstall the latest kernel. I now get an error message when booting: /dev/mapper/vg_jvermeulen-lv_home does not exist. I can boot into single user mode and run all commands. in fdisk -l .....lv_home is not listed. How can I re-add this? I do

Hello All, slightly unrelated because lightdm = epel, I know. Still, maybe someone had the same issue.

Hello All, I'm trying to use vi commands instead of using the mouse. I open Gnome-Terminal I open a file : vi /home/jvermeulen/.ssh/id_dsa.pub I select the key with " V " ( visual line ) I type " y " to yank the selected line. I can now use :e otherfile.txt and paste the text in otherfile.txt This is the only way I succeed in copying text to another file in

Dear All, I'm replacing an older OpenSuse server with a new Centos6.4 server. So far that goes ok, except that the OpenSuse server is also a samba server with ldap connection. Since I replaced all but 2 machines in the building from Windows to Linux, I was hoping not to install Samba on the new server. ( And also because I can't get it to work on Centos. ) I saw a post on the
